I can't find the thermostat of my car?

I have a 1993 lexus ES300 I am trying to change the thermostat because it%26#039;s overheating but I can%26#039;t find it. Does anyone knows where it might be, I will really appriciate it. Thanks|||Dear Lexus-





Don%26#039;t be took quick to judge the thermostat for your vehicle overheating. There could be some other issues that youmight consider looking at.





Unless you have had the car diagnosed, and know for certain that its the thermostat that is sticking closed that is causing the problem you need to check a few other things first.





Finding out WHY the car is overheating is necessary to solving the problem.





Here are a few things you can check on your own.





Is the car getting hot while the A/C is on and you are driving in town?





If Yes, then it could be a faulty temprature control switch for the Engine Cooling Fans or their motors have burned out.





Does the engine temprature return to normal ranges when you are driving on the highway? Then again the above answer would apply.





Have you checked the Coolant Level to be sure that it is properly filled?





Low Coolant Levels can cause overheating.





Have you checked the Radiator Cap since you purchased the vehicle, and has it ever been replaced?





This can cause over heating of the system cannot build the proper amount of pressure.





Are there any leaks from hoses or a water pump?





This contributes to low coolant levels and overheating.





Have you had the cooling system pressure tested and serviced? The pressure testing can locate internal leaks such as blown head gaskets, corroded freeze plugs and other things of this nature.





These can lead to overheating.





A partially blocked or leaking radiator?





Leaking Heater Core?





The reason I say this is because the weather is getting warmer now that Summer is here. I have been seeing the questions on this board being more and more frequent about Cooling system problems.





Here is What I would recommend that you do.





First have the cooling system pressure checked for any leaks. Then drain and flush the system, then have it refilled. Re-check for any leaks.





Have a complete diagnostic done on the Cooling System so if there are and electronic problems, they can be addressed and repaired.





I hope this helped you out.|||Follow the hoses back from the radiator. it will be the hose that connects higher than the other. Take off the hose and remove the peice that is bolted to the block the thermostat is in there....Good Luck|||follow the top rad .hose it will lead u to it,,,,,it will be on left side over the tranny|||Follow the top radiator hose to the engine. It stops at the thermostat housing There should be 2 to 3 bolts holding the housing to the engine. When replacing it make sure you put the thermostat in correctly.


The side with the big spring faces the engine if you get confused or forgot to look.|||Hi, if you will follow your top radiator hose to the motor the thermostat should be at the end where you will see two bolts where your radiator hose ends. the thermostat is under there

Broke something while changing the thermostat?

While my husband was taking the thermostat housing off of our 3.3L 200bbl engine, he accidentally hit a sensor type part on the left and it looks like it broke. What is the part and can it be replaced? The problem we are having now is that the car stalls when it is idleing.|||need year make model|||Buy yourself a Chilton or Haynes manual. They%26#039;re about 20 bucks from any major auto supply store. The information contained in those books is tremendous.

Why dose my car keep over heating, i changed the radiator,AC condenser,and thermostat, but still getting hot ?

i have a 99 dodge neon that i have as an emergency car if my other car brakes down but it has been getting hot i changed the radiator because it was old and spraying out water also the AC condenser, cus it had a hole in it, then i changed the thermostat but it still gets hot when i turn on the AC the compressor is new but still don%26#039;t know what else is making the car get hot!|||it could have an air bubble in the system, the heater core could be pluged..||| Check your heater core, the thing is probly cloged.

Polo overheats despite change of thermostat

The coolant level is correct. The thermostat has been changed. the car boils over after being driven a few miles. What could be the reason.|||Most likely the waterpump impeller has came loose from the shaft. When it spins slow it grabs onto the shaft. When it turns fast the impeller slips on the shaft.





First thing to do is once is gets hot, after ripping around the block. Get out and pop your hood. Check to see if coolant is flowing back to the coolant bottle from the little hose connected to the side of it. It not then let it cool down and...





Under the intake on the passenger side is the thermostat housing. Two 10 mm bolts hold it onto the block. If your next to the alternator, your in the right spot. Take those out and pull out the thermostat. Stick your finger in the hole and to the left and feel the waterpump. You shouldn%26#039;t be able to move the waterpump impeller. If you can spin it with you finger, then it%26#039;s bad.|||Thermostat is not opening. BECAUSE the way you refilled the coolant was wrong. You have air on one side of the thermostat(and air never gets hot enough) to open the thermostat...so you overheat.


To correct. Let it cool. Pull off lower rad hose and drain block and rad of coolant(again) Now put on lower rad hose to rad and the thermostat housing to the block. Pull off top rad hose and pour coolant down the hose pipe into the motor and fill it up. When full, reconnect rad hose to top of rad. Now fill the rad and the overflow container. Now coolant is on %26quot;both%26quot; sides of the closed thermostat.(no air pocket). Car should work fine.//Note: this will also be the reason why the fan was not coming on either,,,because fluid was not flowing past the temperature sensor for the fan.


The Most Likely reason|||This could be bad news. It could be a blown head gasket. I had one on a Datsun pickup truck. The engine heated up very quickly. I repaired it myself. When I removed the head I had expected the head gasket blown to bits and pieces, but all I could find was a tear from one of the head bolts toward the cylinder. I guess because of the pressure in the system the water quickly ran into the cylinder.





So one test to make to prove that the head gasket is blown is to take out the spark plugs and then crank the engine to see of any water is coming out of any of the spark plug openings.





Please, don%26#039;t assume that I am correct with this, don%26#039;t take off the head until you have evidence that what I suggest is indeed true. LOL |||is the coolant system a pressurized system? if it is and you have opened it it will continue to overheat until you bleed the system

My car is building up pressure in the radiator, i changed the water pump, thermostat and radiator.?

I drove it today, had heat and everything, when I turned the car off and checked the radiator, it was like a fountain of antifreeze...what could cause this?|||The radiator cap should NEVER be removed while the engine is hot! The cap is designed to hold a certain pressure in the cooling system to keep boiling temp of the antifreeze down. The cap will release pressure when it exceeds about 15 psi so any extra pressure caused by any leaking gasket into the cooling system will be released.





If you are concerned about too much pressure in there have the cap tested it should release any pressure over about 15 psi. NEVER open a radiator cap when the engine is hot!! You could scald yourself or anyone near by.





j|||Blown head gasket. Find a good independent mechanic.|||Fountain of antifreeze, when you opened it?





Well, if so, it%26#039;s normal, hot coolant expands and will spray if radiator cap is removed.





However if it%26#039;s building up too much pressure and you hear bubling, your head gasket might be failed, thus letting the combustion gases to enter the cooling system. Not a good thing.





Good luck.|||NEVER open the radiator cap when the engine is hot.The cooling system is under pressure once the engine reaches operating temperature.Its suppose to build up pressure.|||Leaking head gasket get it done asp.As others have said never remove a radiator cap with the engine hot.|||It%26#039;s a good idea to get the whole system %26quot;flushed%26quot; every now, and then. Sludge builds up|||check your hoses it might have cracked form cold to hot weather and this will lose pressure in the hose and possibly build up pressurre in the radiator very uncommon though. u also might have somthing cloged in the hose itself. if u already did all that work to u might as well change the hoses. other than that i dont know what to tell you.|||cracked block did u over heat or freeze?|||Do a compression test,you may have a slight head gasket leak into the coolant system.Also while running at warmed up running temp , leave rad/cap off and inspect the coolant at the neck for bubbles .this is a sure sign of a internal coolant leak. also check your dip stick , Oil turns a light tan color when contaminated with water or anti freeze.|||I trust you saw the CAUTION DON%26#039;T OPEN HOT label.


It%26#039;s on the cap for a reason


If your still building pressure, time for a head gasket


Worse case, a head|||either you did not get all the air out of the system,,,or possibly have a blown head gasket|||Thats normal.If you remember high school chemistry, when the coolant gets hot, it expands in volume because the molecules are in a excited energy state. Its the same as a pressure cooker, when it gets hot, and you take the lid off, steam spews everywhere. Most coolant systems operate somewhere between 10 and 20 psi.





If you want to check the coolant level, let the car cool off to the air temperature, or at least until you can put your hand on the engine and its only slightly warm.





My truck has an overflow cap that opens when the coolant pressure reaches 16 psi so that the hoses don%26#039;t explode.

Why would my car's heater not make the air warm if i already changed the thermostat ?

Car is overheating since I changed the thermostat. ?

I changed the thermostat in my Dodge stratus because my heater wasn%26#039;t staying warm when I was at an idle. Since I changed it the heater stays warm but now sometimes it wants to overheat. Is there a chance that the thermostat is bad or in wrong. Whats the deal? |||Hi


The not staying warm when idling was most likely just that it was low on coolant. When you changed the thermostat did you put it in with the pointed end pointing away from the motor? If so then that%26#039;s right. Like already stated may be you had an air block.. let the motor cool off and recheck the fluid in the radiator. it should be full or at least no more that 1%26quot; from the top. I would use the premix antifreeze that way you won%26#039;t dilute you antifreeze mixture if you have to add some.


Good luck


tim|||You probably have an air pocket in the cooling system. When cool, open radiator cap and start engine. Idle until you see water flowing in the radiator.

My car is over heating i change the thermostat, but it is still over heating when i drive long distance.?

when i turn the car off i hear gurgling behind the dash board.|||What%26#039;s the year make and model of your car. If it%26#039;s over 10 years old your radiator owes you nothing. Scale, corrosion and rust builds up in an unmaintained cooling system. The cooling system should be drained flushed cleaned before spending money on a new radiator.





Are the electric fans running? Is the radiator cross-tubes and fins clean? Drain and flush the system. Try two 33 oz. plastic bottles of Prestone Super Radiator cleaner fill till full with plain water. Drive the car at least 200 miles before draining and flushing again.|||That%26#039;s some BS.

Either your radiator is not full or you%26#039;ve added too much antifreeze or you only have antifreeze in your radiator. It%26#039;s suppose to be 50/50 mixture. Antifreeze holds heat better than water, that%26#039;s why it%26#039;s great to have it in the summer. It doesn%26#039;t react to heat as fast. However, too much antifreeze holds too much heat and causes your car to over heat. Does your radiator/hoses have any leaks or did it and you were adding straight antifreeze.

My car heats up fast even though I changed thermostat. Instead of hot air, it's cold. What's going on?

Please Help! I have a Dodge 2002 and it%26#039;s been so much trouble recently. I drove from TN to CA and as soon as I got to LA, I had to LITERALLY stop every 2-3 miles to cool off my car. Before driving in a long distance, I changed thermostat. I had to stop because the heating arrow will go all the way up. I%26#039;d take off thermostat and let it cool off then put it back. Radiator guys told me there was an air when I was changing thermostat so they did smt. I was afraid my accumulator is starting to mess up and my car is useless, but they said it%26#039;s fine. My air conditioner was working perfectly for about 2 weeks until the arrow went back up again. Does anybody know what%26#039;s going on? That would suck if I have to replace my waterpump cause it%26#039;s so pricey|||CHECK THE FAN, IT MIGHT NOT BE WORKING PROPERLY|||did you drill a little hole in the thermostat before it was installed? This keeps the air from getting trapped where coolant SHOULD be.


http://www.mgfcar.de/thermostat/Dcp_5568鈥?/a>


also make sure your antifreeze is mixed 50/50 with water!





when the heater blows cold, that means there isnt enough water in the system.|||There is a thermostat which regulates the flow of coolant, and then there is a temperature sensor. See if you can find/replace that, it may be giving false readings.


If there%26#039;s air in your coolant system, leave that cap off that you%26#039;re not supposed to take off when the engine is hot and run it with that open till it stops bubbling. (if there is air in your system however, you would get %26quot;bubbles%26quot; where your engine temp would rise at a swift rate and then return to normal after a little while)


Has the level of coolant been going down? If it hasn%26#039;t then your water pump is likely fine, they tend to leak when they go.


Otherwise I%26#039;d say maybe it%26#039;s a head gasket?


And check to see that the fan is working first of course.

What is the average repair time of a thermostat on a car.?

I know the part is only about $25. I have a 2000 VW Golf Gti with the 1.8t Engine. My car takes forever to warm up so I suspect it%26#039;s about time to change the thermostat considering i%26#039;m at 180,000Kms.|||1.5 hours by an experienced mechanic. 3 hours for a shade tree mechanic. Days if you do it yourself and a bunch of $$$$$$.|||Not an easy one on the vw/audi 1.8 turbo. I%26#039;d say 3 hours if you%26#039;ve never donw it before. Most of the 1.8T%26#039;s need the intake manifold to be removed to perform this.





Another thing on the 1.8T%26#039;s: Make sure you replace the timing belt every 65K miles, regardless of what your manual tells you. I%26#039;ve replaced several 1.8T engines for customers due to timing belt, tensioner and water pump failure.|||On any car you%26#039;re going to be paying a lot more for the labor than for the part to replace a thermostat. I%26#039;ve never done it on a VW but I%26#039;d guess maybe 2 - 3 hours. This means over $100 for labor. Possibly well over $100. That is of course if you%26#039;re paying someone else to do it. If you%26#039;re up to it go for it. Also, replace the gaskets you break the seals on (180000km!)

When I idle my car overheats, I changed the thermostat and fans are working , what could it be?

Cooling fins in radiator are dirty. Spray through the radiator with a garden hose so you can see light between the cooling fins.

My car had that problem, They replaced that pipe with gasket and it became all right.|||Check your radiator fluids. It sounds to me like the water pump is going out or is already gone.





What kind of and year of vehicle?|||Check for a leak in the radiator. Also, could be the sensor that turns the fan on when the car is in idle. The fan new cars do not come on until the temperature reaches a certain point.





See if you have a water spot under the car after it has been turned off for a while. If you do, then the Water Pump is a very likely problem.|||It could be many things. You say the fans are working. Is the car overheating when the fan is running? Does the car stay at proper temp when you are driving it?





Some cars have to have the air released (bled) from the cooling system. It couls also be a clogged radiator. More infomation is needed to be of any more help.|||If you have the proper amount of coolant and the radiator cap is good, I would suspect the radiator core is partially clogged.





When you are moving the air passing through the radiator helps to dissipate the heat. The next time it occurs turn the heater and the fan on full. This basically adds about a gallon to your cooling capacity and also dissipates the heat. Did the temperature drop?





Any good radiator shop should be able to analyze this.

I just changed the thermostat in my 99 honda civic and now my car won't start. ?

Do you think the hot antifreeze caused something to go wrong? This car is pissing me off!|||My husband had this problem. Turns out he installed the thermostat wrong. Double check that. Also, you don%26#039;t indicate if the car will turn over but not catch, doesn%26#039;t turn over, what - that is very important. Did you disconnect something you didn%26#039;t reconnect?





|||Make sure you reinstalled the ground wire that connects to the thermostat.|||Changing your thermostat shouldn%26#039;t affect your car from starting, especially if your car started before your thermostat replacement had been performed. The only thing hot antifreeze could do is blow a crack through your radiator while the high heat on your engine could damage your sparkplugs and ruin gaskets that could cause leaks around your water pump.





Work your way through the general process of troubleshooting when your car doesn%26#039;t start.





Make sure your battery is fully charged; does it need a jumpstart?





If your car sounds like it is just making clicking or whizzing noises when you turn your ignition key, do you need to replace your starter?





When was the last time you changed the spark plugs and spark plug cables?





There are a lot of other things you can double check but try those first few before getting a little deeper into troubleshooting.





Good luck!

Is it safe to leave off a thermostat on a car?

My car temp. keeps rising and i have changed every hose and anti-freeze...did a radiator flush but temp. still rises....someone told me to change the intake gasket and thermostat...another friend told me leave the thermostat off and run it like dat?...is this safe?|||It won%26#039;t kill you ,so it%26#039;s safe. But it will make the motor run rich longer because of the longer time it will take to come up to operating temperature. This will carbon up the cylinders and probably throw codes. It may load up the cat converter and cause it to fail. Not the best idea.


You should get a master mechanic to diagnose the problem. It could be the electric radiator fan is not functioning as it should, or that the water pump is not working. It may be that you have a bad head gasket and that an air pocket keeps forming in the cooling system.


Changing the thermostat is the first thing I would have done.


Something is causing the problem and you had better get it fixed before you do major motor damage.|||no|||it is safe.|||yes, you can run without a thermostat, but your heater will never get hot...





I%26#039;d suggest a new thermostat rather than %26quot;no%26quot; thermostat, since they are rather inexpensive...


you may also want to check your fans, and make sure they are working properly...


finally you may need a new water pump...





as long as you don%26#039;t have any big bubbles in your coolant system, and your head gaskets arent blown... you should be right as rain|||Safe, yes.


Smart,no.


Your engine running hot could be a bad sensor, a plugged fuel filter, a vacuum leak, poor timing and several other things.


In short, you just need to get some things taken care of, not putting a thermostat in it may cure the symptoms but not the real problem (which can lead to an early death for the engine and car).|||Since temps keep rising, suspect a blown head gasket. Is the vehicle expelling coolant when it gets hot? If so, almost certain head gasket is blown.





Running without a t-stat will not allow the engine to get up to normal operating temps and keep the engine running rich, which will reduce fuel economy.|||It is not good. The piston can get hot and expand while the block stays cool and compact. That combo spells disaster.|||your car will not heat just change the thermostat|||It is safe, in that it isn%26#039;t going to blow up or anything. However, Your defrosters and heater will not get hot, so clearing the windshield may be a problem, which is not safe.





Also the engine running hot may be the result of something else being wrong with the engine. Your engine may also run rich if you pull the thermostat, the computer will think that the engine is still cold and will throw more fuel into the cylinders which isn%26#039;t good for the engine.





The best thing to do, is to have the problem corrected and to replace the thermostat with a new one. The car will perform better and you%26#039;ll save gas too.





Good luck with it.|||Put a new thermostat in correctly (i have seen them in up-side down)


Make sure the cooling fan works. If the car has air conditioning, it may have a fan clutch that is freewheeling. Get it replaced.


If no fan clutch make sure the cooling fans work, bad relay, bad senser will allow overheating.


Best I can do with no details to work with.|||You can run it if you want to but your vehicles computer (ECM) will make the car run worse since it is removed, just replace it with the correct one in degrees and not higher or lower.|||if your temp keeps rising you probably have a head gasket problem.do not run without thermostat because you will not know if you are overheating,you could do major damage with out knowing.|||If the temp rises only when the vehicle is stopped, such as at stoplights or when idling parked, and if the temp goes back down after you get the car moving, then your thermosensor (sticking out near the bottom of the radiator in my Honda) has probably gone bad and is no longer telling the fan to come on when you don%26#039;t have wind coming through the radiator (because you are stopped). It is a very cheap fix.





Also, a stuck thermostat will cause your problem. Also a very cheap fix.





At many auto parts stores you can buy a Haynes do-it-yourself manual for your model car, with step-by-step instructions, and basic explanations at the beginning of each chapter. If it is not in stock, you can order it online by searching on %26quot;auto repair manuals%26quot; on Yahoo search. In the front is a section on %26quot;Troubleshooting%26quot; that guides you step-by-step to find causes of most engine malfunctions based on the car%26#039;s symptoms. Whether you do the work yourself or not, it helps you make informed decisions, to understand your mechanic and not be taken advantage of, and to not feel so %26quot;in the dark.%26quot;





db667089 says: you can check http://www.alldatadiy.com. For about the same price as a Haynes or Chilton%26#039;s repair manual, you can have online access (for a whole year) to model specific info for your particular vehicle. This is the same info that repair shops use. They have great wiring schematics/diagrams.





Also, for about $15 for a one-month subscription, you can get the factory manual, downloadable (careful! Mine was about 500 pages!) or viewable, at http://eAutoRepair.com.|||no, put a new thermostat in it and have the waterpump checked and make sure the fan is working properly.

Is changing the thermostat on honda civic a pain or pretty easy?

My heater is crapping out on me and its winter and snowing, kind of need my windows defrosted before i drive to work in the morning, someone suggested might be the thermostat, I know what it is but havent changed it on this kind of car before, wondering if anyone thats doen it could tell me if its pretty quick and simple or does it take a little bit of time? thanks|||it is only a pain if you dont have an extension about one foot long, the bottom bolt is nested down between the head and the top of the tranny. just remove the air cleaner and air pipe then go to town on it should be two 12 or 13mm bolts make sure to get the rubber thermostat housing seal also %26quot;most rip when removing%26quot; and your good to go!!|||It could be a number of other problems, possibly the heater core, blower motor, or an electrical problem. What exactly is the problem? The thermostat controls the circulation of coolant through the radiator and engine. Have you noticed any fluctuations in engine temperature? If your car is running normally and your heater isn%26#039;t working, I would check the heater-related components first. Signs of a bad heater core include condensation on windows/windshield, %26quot;sweet%26quot; smell when the heater is turned on, wet spots on the floor, and coolant loss.|||Its 2 bolts and 5 minute%26#039;s of work and topping off the antifreeze once done oh yea and its a 10mm bolt and honda does not use a 13mm bolt underneath the hood

Which of the hose am I supposed to unplugged to replace the thermostat of my car which is a Mitsubishi Galant ?

I have a 2002 mitsubishi galant and wanna change the thermostat so my radiator will be well regulated. There are 2 hoses, 1 on top which is short and the other one at the bottom which is longer. I can locate both but do not wanna unplug the wrong one. If you can help me figure it out. Thanks|||I don%26#039;t know that particular car, but read on. I%26#039;ve had an awful lot of cars apart. The thermostat will be located where the upper hose connects to the engine block. Take the thermostat out and put it in a pot of water on the stove and boil the water. If the thermostat opens, it%26#039;s good. It%26#039;s a good idea to replace all your hoses and belts every few years. The soft parts of cars wear out first. If one hose goes, so will the other one, and also the hoses for the heater. Every time a hose springs a leak, all your antifreeze will leak out, so just replace them all and live happy.|||i%26#039;ve probably had more cars apart than the first guy and have never tested a thermostat. if you got the thing out.....PUT A NEW ONE IN!!!!





But yes, follow the top hose to the engine block. the thermostat should be there. if you have any doubt, seek professional help. or go semi-professional and go to autozone. surely they have someone halfway intelligent in there.

What causes a car to run cold all the time other than the thermostat?

The car will run normal temp after sitting at idle. But once you drive it around it drops back down. I have already changed the thermostat and it did nothing at all.|||Don%26#039;t complain, you have a cool running car, the only thing I can think of is the fan if electric is kicking on at the wrong temperature and keeping it too cool.

Soon as I start my car it gets hot i change the thermostat and still hot whats the problem?

without knowing year make and model i am going to go out on limb and say check your waterpump. start the car without the radiator cap on and wait for the temp to come up, if the water gets hot right away and doesnt seem to be circulating through the radiator the water pump is no longer working.





someone mentioned a head gasket but you can easily check this without tearing into it. with the engine cold (preferably in the morning) pull the dipstick and look to see it there is any coolant on the stick. remember not to wipe it as soon as you pull it otherwise you will get a false reading.|||head gasket needs to be changed|||have you checked water levels ?|||Does it REALLY get hot, or is it just indicating it is? Do you see steam, hear boiling water?





Chances are it isn%26#039;t really getting hot, and all you have is a bad sensor that needs to be changed out.|||By as soon as you start the car do you mean immediatly? If so then it could be your temp sensor has gone bad. If it takes a min then starts to verheat I would check the coolant level, If that is good try flushing the coolant.|||when it gets hot, do you get any heat in the car? like through the vents or defroster? You could have a bad waterpump or be as simple as low coolant. even if it seems up, some cars have a hell of a problem bleeding the air out of the system. if there is a bubble and won%26#039;t circulate the coolant. hope this helps you.|||check your radiator|||Before ANYONE can answer this properlly. What year make and model do you have. This little bit of info can help alot.|||Your car will overheat if:


-Thermostat is stuck open


-If the fan is not working


-If it%26#039;s got an electric fan there may be a problem with the relay or the thermo swtich or the fan itself. YOu can connect the fan directly to the battery to make sure it%26#039;s working


-If not an electric fan the problem may be the fan clutch


-The hoses could be soft and compressing blocking the flow of antifreeze


-You could have a leak somewhere.


Your head gasket may be blown, this can be verified by doing a compression test, inspecting the oil for the presence of coolant or inspecting the coolant for the presence of oil

I change water pump an thermostat and when on xprsswy car runs extremly cold what could be the problem ?

i change water pump an thermostat on a 97 sunfire 2.2 and when on xprsswy car runs extremly cold an i lose all heat what could be the problem ?|||was the thermostat the correct one for your engine?|||You probably have an air lock in the cooling system and it is not full of coolant. It could be that the thermostat is stuck a little open or not seated correctly or backwards, but I rather suspect you need more coolant in your system. Park the car with the nose a little uphill and after it cools, check the coolant level.

Is this a bad car thermostat?

I have a 1995 Chevy Monte Carlo, when I get the car going, after it warms up, the temp gauge will go to hot , but the heater will blow out cold air then all of a sudden the temp will go down again and I get some heat through the heater. This keeps going on with it going up and down. Does this sound like I need to change the thermostat??|||probably a bad stat and low coolant.|||I would change the thermostat first, but that%26#039;s not the problem, its just one part of the problem. Something is wrong with your heater. You might check it by feeling if the return hose is warm when you%26#039;re having all these problems. It also sounds like there is some relay that is not opening the heater doors.|||Yeah it does sound like the thermostat is dodgy. For a start it shouldnt go all the way to hot from what iv been told. That is a sign off the radiator over heating. It should stay in the middle between cold and hot. Take it to a mechanic or get a family member or friend who knows a lil something about cars to chck it out!


Good luck :)|||It does sound like your thermostat is sticking.|||Sounds to me like you have air in the cooling system and need to bleed it first|||it sounds like it i would start with that is the cheapest part|||yeah or u must have a major electrical problem|||sure

Car overheating, already changed thermostat?

1966 dodge dart keeps overheating. I replaced the thermostat because the car would get hot, then cool down, and vice versa. It does the same thing with the new thermostat. What is causing this problem, the temp guage goes all the way to hot and the car backfires.|||Check the timing on the car, It may be too advance. Also backfiring is an indication of anti freeze in your cylinders, You may have a leaking intake manifold or a blown head gasket. I hope its not a crack block. Do you charge your anti-freeze regularly. You may start by having the radiator cleaned. hi happened to me once when I changed the thermostat in my Olds., The thermostat did not seat properly|||You need a water pump or your radiator is all plugged up. With the radiator cap off and the engine idling,look to see if the water flows rapidly, of just sits still in the radiator. Watch your face so if the water boils and sprays out,you don%26#039;t get scalded.

Is It OK to drive a car without the thermostat? If yes, for how Long?

I%26#039;m assuming that my thermostat sensor or something is not functioning properly. When I drive my car, the top radiator hose is hot but the bottom isn%26#039;t. My car tends to overheat about an hour of driving it. I change the thermostat but the problem still exist. What could be the problem?|||I%26#039;ll just give you the simple answer good for %26quot;most%26quot; vehicles..... yes, it%26#039;s ok..... but in winter it will take much longer for your heat to work, as you aren%26#039;t letting the water to heat up long enough to produce heat. without the thermostat, the water/anti-freeze will free flow through your engine and radiator.|||this is a bad idea. you will definitely see some adverse effects in this situation. the coolant will take quite a while to warm up . this will cause a big change in your fuel economy. it sounds like you have a blockage in the radiator. if the upper hose gets hot (like it should) but the lower end stats cool you either have a blockage or a failed pump. on some of the newer cars you can find an electric water pump this could present a problem in your situation if nothing else is obvious, like stiff steering or a charge lamp that stays on. this would all signify a thrown belt. |||Are the radiator fans coming on? If so, you could measure the temp of the upper rad hose with a laser thermometer and see what the actual temp is. maybe your gauge is not reading right.|||Could be a huge airlock or blocked rad core.|||Again, I wish you%26#039;d have included the year make and model of your car. If it has electric fans are they switching on? If so do you have the original radiator? How old is the car? Do you have a silicone filled thermostatic mechanically driven fan hub? Do the blades speed up as the temperature rises? Have you ever used any products along with the antifreeze such as Barr%26#039;s Leak or ant brand of stop leak? Do you still have plenty of heat coming from the heater?





As a general rule of thumb drain the radiator and flush the system with a Prestone flushing T in the return hose from the heater core. Flush till the water is clear. Drain the radiator of the clear water. Dump two 33.5 oz. plastic bottles of **Prestone Super Radiator Cleaner in the radiator. If it will not all fit. Pull off your coolant recovery tank and clean it out with Wisk and a round bristle brush. Dump the remainder of the cleaner inside the coolant recovery tank. Auto Zone and Advance Auto has this product. Do not substitute with anything else!





This cleaner is unlike the other Prestone product: Prestone Radiator Flush. The instructions say to actually drive a minimum of 200 miles with the cleaner inside the cooling system. At the end of the bare minimum 200 miles flush and drain again till the water is clear.





At this time install a new Stant or AC-Delco thermostat (correct heat range) and a new closed system radiator pressure cap -minimum 13 lb. If this car were mine I%26#039;d drive it a week with nothing but pure water and a bottle of NAPA%26#039;S cooling system anti-rust so as not to waste expensive antifreeze if the radiator, radiator hoses are collapsed in the center or radiator core is seriously plugged with corrocion, rust or stop leak. If the motor runs within its normal heat zone for a week or two, drain and flush and do your antifreeze thing.





Please be sure you%26#039;re using the proper type of antifreeze. Buy a couple gallons of 100% antifreeze. When ever you re-fill any cooling system look in your handbook in the specifications page and find the cooling systems capacity. Pour exactly half the capacity first with 100% antifreeze. Make sure the coolant recovery bottle is clean. fill the coolant recovery bottle with any antifreeze you were unable to fill in the radiator. For the first week or two keep the coolant recovery bottle nearly full with water only after half the capacity of the cooling system has been met with 100% antifreeze. The coolant will drop noticeably during the first week or two of driving keep it a minimum of 3/4 filled at all times. The heat cycling of the coolant purges air from the cooling system causing the water leval to drop. This will stop at the end of 100 -200 miles of on and off driving.

Overheating 99' Chrysler Concorde and changing the thermostat?

My 99%26#039; Chrysler Concord with a 2.7 liter six cylinder is overheating in traffic. The electric fan does not turn on when the temp gauge is climbing. Would a themostat cause both of these problems. Is the thermostat right on top of the block under the line to the radiator like in older cars? The last car I changed a thermostat in was a %26#039;75 AMC Jeep CJ-5 so I am a little behind on the technology. Any help or advice is welcome?|||You have a thermal switch that senses temperature.It should have only one wire to it.When it closes on temp. rise,it sends a ground to the fan relay.If you jump out the wire on the thermal switch to ground,the fan should come on.(Make sure your ignition is on when you test this)If the fan comes on the thermal switch is bad.If the fan does not come on you need to find the relay and determine if it is bad or has a blown fuse to it.|||Yes the stat is still on the block. However those electric fan motors also have a sensor, which could be the problem. In which case you may want to have them replaced. Use a jumper line and direct feed the power, bypassing the sensor, and run continually. Hook the line to switchable power source, like ignition. If you are going to change the stat, back-flush the cooling system first. Use a product like Zerex or Prestone raditor flush.|||I don%26#039;t think a thermostat would cause both problems. It would cause over heating if it was stuck closed but it would not prevent your fan from coming on. You should follow your top radiator hose to the engine block. The thermostat should be inside the hose.





The fan may not be coming on because you might have a blown fuse or possibly a solenoid or relay is not functioning correctly by letting the voltage through to turn on the fan or the fan may not be grounded. I would say that there should be a device to let electricity through to the fan when the engine reaches a certain temperature to turn on the fan but I don%26#039;t know what it is. On my prizm it was caused by a relay in the fuse box.

I'm trying to change the thermostat in my car?

I have a 95 Monte Carlo Z34. Anybody know a site I can go to for instuctions? Or better yet anybody know how to do it?|||OK, its not a bad job at all. To locate the thermostat follow the top radiator hose to the engine. On most cars the thermostat will be located under where the hose connects to the engine. So first remove the hose on the engine side. By the way do this when the engine is cool. Now remove the thermostat hosing. Usually two bolts. Now you should see the thermostat. Clean both mating surfaces, replace thermostat with new gasket, gasket sealer is recommended re-attach the cover and then attach the hose. Top off coolant. Your all done!

Changing thermostat for Toyota Camry 2000?

I have Engine check light ON, the error message is P0128.


With reference to my post yesterday, i might have to change thermostat of my car. Now i have two questions





1. How do i find out that Thermostat is not working ?





2. Is it possible to replace thermostat on my own ?|||1. Boil a pot of water on your stove, now drop the thermostat into that water and you should be able to see the thermostat open up. If the thermostat doesn%26#039;t open than it is bad and needs to be replaced.





2. Yes you can replace the thermostat on your own, it%26#039;s really quite simple. Make sure when you buy a new thermostat that it comes with a seal because this eliminates the need to buy a separate gasket. Before installing a new thermostat, place the new thermostat in boiling water so it can open up for the first time. Sometimes if you don%26#039;t do that than your car will overheat before the thermostat opens up for the first time. To locate where the thermostat is on your vehicle, follow the upper radiator hose to where it meets the engine. That is where the thermostat is located. You didn%26#039;t mention what engine you have but you may need to remove something to gain better access. Now drain your coolant into a clean container because if your coolant is in good shape you can reuse it and you don%26#039;t want other contaminants in your coolant. Now just remove the thermostat housing which usually just requires removing a couple bolts and pull the housing away from the engine. Remove the thermostat and clean the surfaces of the housing and the engine so you get proper seal. Install new thermostat in the same way it came out, DON%26#039;T INSTALL IT BACKWARDS!!! Now put everything back together and refill your cooling system with either new coolant or reuse your drained coolant if it is still good. Run your car for fifteen minutes, make sure it doesn%26#039;t overheat, check for leaks and top off coolant as needed.





Good Luck!|||In reverse order, yes you can replace the thermostat yourself. Get yourself a repair manual for your vehicle and it%26#039;ll walk you through it. It%26#039;s not hard at all. As for testing the thermostat, there%26#039;s a couple of ways to see if it%26#039;s opening or not. First, take the cap off the radiator and start the car. Let it warm to operating temperature and then watch the coolant in the radiator. It it%26#039;s moving then more than likely the thermostat is opening and doesn%26#039;t need replacement. If you don%26#039;t notice any movement of the coolant, you can remove the thermostat and put it in hot water. The thermostat body should have a temperature stamped into it and if you place it in water that temperature, you should be able to see it open.|||A simple test to find out if the thermostat is opening or not is to heat up some water on the stove to about 180 degrees, and then place the thermostat into the water. If it is working properly, it will quickly open up.





you have to drain some of the coolant.


to locate your thermostat, look where the end of the top radiator hose leads to the engine,at the end of the hose is the thermostat housing, the thermostat is inside it....





take out the thermostat housing you will find the thermostat.





(your going to need new gasket when you put it back)

How do I change the thermostat on my car?

Is it something that I could do myself (I am pretty good with cars, as is my husband) or should I take it to the shop and have them do it?


It%26#039;s a 2000 Chrysler Cirrus if that matters|||It depends on the car, but mine takes me about 2 minutes to do.


Usually it%26#039;s a really simple procedure.


What size motor is it?|||If you can change your oil, you can change a thermostat. $10 and you%26#039;re done.|||take it in to a shop. chrysler thermosta housings are made plastic. and a tendacy to brake when removing it. if all goes ok parts and labor should around $150.00 at most.|||$150!!!!???? no way!


Its easy enough, its in a housing where the hose from the radiator meets the engine block,


Disconnect the hose from this housing. (coolant will piss out, never worry.)


Undo the bolts (usually about 3) on the housing that hose came out of.


It should come off/apart exposing the old thermostat, tap or twist it out.


Flush the engine and radiator with water, and drain out as much as possible by removing as many hose connections as u can see.


Replace new thermostat into housing, (pointy end toward engine) and re-assemble housing, making sure all mating faces are clean and smooth for a good seal!


Re-connect all hoses.


Replace new coolant mixture into the coolant tank, It will only let u put in about half, as the thermostat it cold/closed and it cant circulate.


Run the engine, once the thermostat opens/warms, it will suddenly drag the coolant through the engine, top it up again and switch off when it gets too hot!!! repeat till the coolant is fully circulated and the level stabalises.


Mine took about 6 litres, depends on the car tho...|||Varies from car to car, but most have the thermostat in the top radiator hose housing on the cylinder head.


To change it, you remove the housing, pull out the thermostat, clean out the inner housing, replace the thermostat using a new gasket or silicon sealer if you don%26#039;t have a gasket, and replace the housing and top radiator hose.


Not a big job. If you%26#039;re unsure get a copy of the auto manual from your local library just read and confirm.

How often do I have to change the thermostat on my car?

Also, how often do I have to flush my radiator?|||Thermostat only needs to be done if it fails or weak.

Over heating car changed thermostat,acting really weird?

one day my heat quit working in my (95 taurus 3.8)so i got on the free way and it started blowing luke warm then 10 min later it was blowing hot as soon as i got off the freeway it started blowing cold instantly,i took it to a shop and had the thermostat replaced,he even took the hoses off the heater core and blow it out,and still the same ,after leaving the shop it was getting really close to over heating so i made it home waited 2 hours and left my house againgot on the freeway(yes dumb)and it started over heating this time the gauge was reading that it was over heating but the car sounded normal and ran normel,but i pulled over anyway and turned the car off and i could hear bubbleing coming from the resivor,got back home safe the next day got in my car and drove it around all day and it was fine,but iam afraid that it will overheat again,what could be causeing it to act like this?|||there my be air still in the system|||Most of these cars have an electric fan that helps keep the engine cool, check to see if its functioning properly.|||It could be a bad thermostat, or one rated higher than what your car is made for. Usually 180 deg is safe. You could have air in the system, check this by starting the car cold and taking the radiator cap off and let it run for a few minutes. Keep an eye on your coolant level, if it goes down, add anti-freeze. After about 5-7 minutes and your coolant level looks good, replace the cap %26amp; check your resevoir %26amp; make sure it is up to the warm/hot line. After it is %26amp; the system is closed back up, shut the car off for 5 minutes. Then start the car %26amp; take it for a drive, this should%26#039;ve taken care of the problem. If it doesn%26#039;t, you might want to have you water pump checked out. Good luck.|||I had a similar issue in my F150 p/u. Turned out to be two things...a vacuum check valve and a %26quot;tired%26quot; diaphram on an airflow gate (door) under the dash. replaced them and now they work like new!|||If you want to be on the safe side, take it to a different mechanic (a competent, conscientious one) and have him replace the Thermostat again, with a high quality brand, and have him check the fan too. Make sure there is heat coming out of the heater, and the temperature is stable before you leave the parking lot.

What could cause a car to overheat even after changing the thermostat? Pressure steam and hiss at top of block?

There could be an air pocket in the cooling system if after refilling with coolant the system wasn%26#039;t properly purged%26gt;|||Radiator fan not working. Could be caused by a faulty fan itself or the relay that tells it to turn on when the car is hot. You should also pressure check your system and make sure your cap is sealing properly.|||Your cooling fan could be bad. Yoiu might have blockage in the %26#039;water jacket%26#039;.


Let the car idle after it is warm and look to see if the fan turns.


Check the fuse for the fan


Always check these first.


Open the radiator cap when the engine is cool. Run the engine until it hits operating temperature and see if the water moves in the radiator.


Try flushing the coolant for the engine. You can buy a kit to do this as most auto part stores.


Don%26#039;t forget to turn on the heat when yhou are flushing. That will help flush the heater core too.|||radiator clogged up, water pump is bad. try flushing out the whole cooling system then see if it,s circulating.

How hard is it to change the thermostat on your car?

All of my fluids are topped off, and the defrost works and the a/c works.. but the heat doesn%26#039;t work. Is that the thermostat?|||seems to me like you have an in-line valve to your heater core that is closed. look under the hood, find the lines that go to the heater core and see if there is a valve, the cable from inside may have come loose. there also might be a cable to the duct that has come loose under the dash area, good luck|||Depends what kind of car...generally they are very easy to replace.|||It%26#039;s easy in mine|||Could be, but could be a number of other things too. If your car is overheating then it is most likely the thermostat. It%26#039;s very easy to replace. Takes about 10 minutes depending on where it%26#039;s located.|||depends on the car if its easily acsesable a piece of cake. unless you do like i did once and used the wrong bolt and broke it part way down. then you need a drill and tap(ps where the world did spell check go?)|||It is very basic, and yes, even you can do it ! Wait until after the engine has cooled. Toward the front of the engine,right on top,( in most cases) there is a big hose. It goes from the radiator to a metal thing that looks like a small softball. There are 2 bolts that hold it down. Unbolt them and the thermostat is right there for you to pull out and replace. Make sure it goes in right-side-up. Take carefull notice as to how it looks before you remove it. Make sure, also, that the gasket is still complete. Good Luck !|||Probably not if the defrosters work. Sounds more like the cable that switches between heat,A/C,etc.Or possibly a vaccuum line is off,(change your radio lately?).|||your thermostat allows the engine to maintain it%26#039;s operating temperature.


If the thermostat is locked open (broken) the engine would have a hard time heating up. Your temperature gauge would stay in the %26quot;blue zone%26quot; and the heater/defroster would blow out cool to warm air.


If the thermostat is locked closed (broken) the engine would overheat. Your termperature gauge would be in the red zone soon after getting on the highway. Your Heater would be producing lots of hot air.


So if both your defrost and heater settings are producing just warm air and your temperature gauge stays in the cold/warm zone, it%26#039;s probably your thermostat.


If the defrost pours out hot air, but the heater does not (they use the same source for heat, the heater core) then you have a broken or damaged flap in the dash that is not allowing the hot air to go through the heater ducts.


To replace your thermostat, go to your local automotive store and pick up a repair manual. It will walk you thru the steps to replace the thermostat. It is usually located in the top front of the engine, held on with two bolts. You may have to drain your radiator to make this repair. The antifreeze is resuable, so don%26#039;t throw it away unless it%26#039;s really cloudy, then recyle it.|||your thermostat has nothing to do with heated ventalation it mearly controls the flow of coolent from the radiotor to the block the problem you are stating is a heater core and its most probably blocked or just jacked up so to fix this you will have to take it out and either flush a stream of water or get a new one which might be cheap or most likely cost you an arm and a leg|||It%26#039;s not hard, but the thermostat controls the temperature of the engine not the operation of the heater?

After I replaced my car's thermostat the engine started overheating?

It was operating at upper normal temp before it was changed, but the car had high mileage and the old thermostat was worn with disintegrating seals. Checked fan, works; checked coolant, full (recently flushed, no sludge); fresh oil change. Let me remind you that the temp was in the upper normal range before the thermostat was changed. Any remedies for the overheating after replacing the thermostat, with no overheating before?|||HI


not saying you did but a mistake some folks have done is


1) put the thermostat in upsidedown. it should point away from the motor (up or out or what ever).


2) not add enough coolant to the radiator (not the overflow tank).. fill the radiator its self when the motor is cold it should be full or no more than 1%26quot; below the top.


3) there may be an air block so run it to tempature turn it off let it cool and recheck the coolant level again.


good luck


tim|||you most likely got air pockets in the cooling system and will have to bleed the cooling system to remove air. air is not nearly as good a heat conductor as water/coolant so it will overheat.|||I would say that you got a air bubble in the coolant system,this happens a lot after the coolant system has been opened. You should have a bleeder valve on are near the thermostat that you can loosen up to bleed the air out,the bleeder looks like a grease fitting.The air bubble gets into the water pump ,causing it not to pump water ,so the engine over heats.|||Pedal to the metal has given a pretty through answer.One other thing,sometimes new thermostats are defective.You can check to see if it is working (opening and closing) by placing it on a hot stove eye,when it gets to it%26#039;s operating temp.,you will hear it click or %26quot;pop%26quot; when it opens.Also is the new one the same temp range as the one recommended for your auto?

How do you know when you need to change your car thermostat?

i just bought a 95 camaro and i want to really take care of it, it recently overheated and that was because the radiator was full of rusty water which wouldn%26#039;t let the water flow smoothly, i was also told that maybe the thermostat wasn%26#039;t working properly, i already flushed the whole radiator and now it runs fine but in case it is the thermostat how would i know when i need to change it??|||you need to change it anyway, the part is cheap and its easy to do , to answer your question if it runs hot again its the thermostat ps get rid of the water and use coolant but be careful if you have any pets it tastes good to them but is very deadly don%26#039;t spill any of it|||I would have changed it along with the coolant flush but that%26#039;s water under the bridge now.


Like many components on a vehicle, a thermostat really doesn%26#039;t have a specific maintenance schedule - it%26#039;s replaced when it fails - no or low heat in the winter or overheating in any season.|||Before it overheats again.|||Most people don%26#039;t replace it as a maintenance item unless they actually fail but they are so cheap that it really isn%26#039;t a bad idea to do it while your working on getting your cooling system in shape. You will know it has failed if your car either takes much longer than usual to get up to normal operating temperature (thermostat stuck open) or it starts overheating right away when you are doing city driving (thermostat stuck closed).|||If your thermostat was bad, then it would still be overheating. If it%26#039;s fine now and running at normal operating temperature, then you don%26#039;t need to replace it. However, if it%26#039;s running even slightly warm, I%26#039;d replace it now. It%26#039;s an easy job, inexpensive and won%26#039;t take you long at all. Heck, you may not even get your hands dirty. ;)|||Unlike every one believes you should change thermostat every two years,on regular coolant cars,and every three to five years on dexcool cars.

How do you change a head gasket in an 89 Honda Accord LXi? Also how do you change the thermostat on this car?

Can you change the Head Gasket by yourself or is it a complicated job for the mechanic only? Where is it located on a 89 Accord engine, and what tools would i need if i am doing it by myself?





Also, is the thermostat easy to replace on this car? If so, is it easily accessible within the engine? Where is it located, and what tools do i need for the job?|||Well I will try to answer the thermostat part. Simply follow the large hose out of the top of the radiator until you get to the engine. There will be a clamp holding the hose onto a metal piece that has two bolts. Remove the clamp and the bolts. The thermostat is underneath and should be easily removed and replaced. Some vehicles have a gasket that is replaced at same time, and should come with the replacement thermostat. Simply reverse the process to install and refill any lost anti-freeze with standard 50/50 mix of antifreeze/water. IF you don%26#039;t know where the radiator is, this repair is best left to a mechanic.


Unless you have a torque wrench, I would leave the head gasket to a mechanic.





Edit- This is far from a fatal flaw in the car as stated above, have it fixed instead of going into debt|||Chiltons.com or autoplus (maybe autopluszone.com) has detailed instructions with photos on how to do many repairs/replacements.|||Although a used honda is still a reliable car, its a waste of time to fix this one. You%26#039;ll be constantly making small adjustments. Get a new used car something from this decade. Go to drivetime if you cant afford financing|||My first car was a white 89 Honda Accord LXi!! I absolutely loved that girl. My head gaskets blew, and I wound up having to get a whole new engine. I got a used one with low milage, and never had another problem with the engine again. Thats all I know though - I left it for the mechanic to handle. And it wasnt too pricey if I remember correctly. I was only 17 and paid cash to fix it.





I never had problems with my thermostat tho, so I can%26#039;t help ya there.|||IF your vehicle is blowing blue, or white smoke and gets sluguis when you bottom out the gas peddal is your head gasket. To do this you need torque Wrench, the engine manual, and about 2 days(since you are a rookie). Ok your head gasket is located between the engine Header and engine you take both of them a part the gasket is between them. The thermostat is located sowhere between your water pump and the cooling hose line should only take you about 1/2 hour to change.

Do i need to use gasket sealant when changing the thermostat and thermostat gasket on my car?

It is recommended to use the sealant, but in a pinch you can put it on with just the gasket that came with the thermostat.

No other sealant will work as well under heat and pressure.

Remove the two bolts, pull the housing off, pull the old thermostat out, and replace it with the new one (making sure it%26#039;s facing the right way). Replace the gasket, put the thermostat housing back on, fill up the lost coolant, and check for air in your cooling system.|||Google blue prints and other info on the net.

Tomorrow I will be changing my cars thermostat, do I have to bleed the coolant?

Do I have to bleed the antifreeze coolant, it is about 80% full.|||Depends on your car some come with bleeders some don%26#039;t. I usually don%26#039;t mess with it unless I cant put the same amount of coolant in that I took out. I assume thats what you are asking. If you are wondering if you need to drain the coolant yes you do.|||Yes, unless you want a major spill on the ground.|||no you don%26#039;t|||you should bleed it because there will be air in it. just start it up and pull 1 of the heater hoses off for a second then put it back on.

Do I need to use rtv sealant when changing my thermostat in my car?

A light application of RTV sealant will not cause any problem used with the o-ring or paper gasket that comes with the thermostat. Just remember the two things that cause trouble with RTV. One is that too much is not better, and the second is that you will have to spend additional time the next time cleaning the RTV off.|||you dont have to use it.some gaskets seals themselves.now mine has a 0ring and dont require a gasket.|||if there was no gasket when you removed the old one then possibly. replace gasket if there was one. if you use rtv be sure not to get it inside of thermostat housing as this could block coolant flow. if ther is any doubt, contact a local mechanic|||You can use a little bit to be sure it seals but most of the time you don%26#039;t need to

i am getting the thermastac changed on my car soon cos it keeps overheating was just wondering weather when the thermostat is changed do they flush the water system out to and if yes will they replace it? any answers?|||Yes they have to drain most of the water out of the radiator when they replace the thermostat. Any half way decent shop would replace all the coolant at the same time. You can always ask to be sure.|||It depends on what you say to them about the coolant.It%26#039;s not water at all. If you need the coolant replaced with a fresh one ,then it is flushed. If there is no need to change the coolant ,then it is topped off to the proper level.
