I need to know why my heat in my car comes and goes?

from what i know about cars you can find the root by elimnation not water pump cause its not overheating not heater core cause theres no anti freeze in or leaking around the car so that leaves me to think its the thermostat and i just changed it i must at though after changing thermost it the heat didnt start right away really need help the car is a 94 caddy sls norstar engine
I need to know why my heat in my car comes and goes?
check fluid level when cool
I need to know why my heat in my car comes and goes?
The heat doesn't start right away because that car has automatic climate control. If you have the temp control set at 70, the heat won't turn on until it can put out air that is at least that warm, which on a cold morning can take a couple of minutes. All cars with auto climate control behave this way.

The heat will %26quot;come and go%26quot; based on what the temperature is set for and what it actually is in the car - just like it does in a house/apartment with forced hot air heat.

If you want the air sooner, you can get around it by using defrost mode instead of the automatic mode, that will turn on right away, but it sounds to me like it's working properly.

Hope this helps.
Do you hear a damper (otherwise known as a mode door) noise? Maybe the damper (mode door) is opening and closing as if you are turning on and off the Heat.,...which could be a bad control head

My car was spewing anit-freeze, what happened?

I have a chrysler 300m 2001. As I was driving down the street, steam started coming into the vents and spewing antifreeze from under the hood as my resivor/temperature light came on. I drove home and parked it. What is wrong? My ex boyfriend says it was proably the thermostat because the air went out first and that it needs to be changed, do you think this is the case? Do you think it would be costly given the type of car, I am on a very tight budget this week.
My car was spewing anit-freeze, what happened?
thermostat and gasket - about 15.00

Time to replace - about 1/2 hour.

on a scale of 1-10 (10 being very hard) this is about a 2.

And this is prob the issue for yours

It does sound like a thermostat, and that is usually the problem. It may also be a bad water pump, cooling fan or just a slipping belt.
it could be one of 3 things - the water pump, the radiator or the thermostat. to me it sounds like the water pump. good luck!
one of yer hoses has hole in it
The thermostat is a very easy thing to change out. But I must tell you if you take it to the shop it will cost more there then if you go buy the part for about 5.00 and have your boyfriend do it.

1998 Grand Am thermostat?

I haven't seen this car yet, but when it gets here, I need to change the thermostat. Need to know where it is. This is a 3.8 V-6.
1998 Grand Am thermostat?
Grand Prix you mean? because the grand Am's don't have the 3.8's Other then that look along the upper radiator hose. you'll come to the thermostat housing. it'll be in here. remember to bleed off the air in the cooling system after you replace it and fill it up with coolant or you will have no heat. There are two little screws. one should be right there on top of the thermostat housing. warm the car up to operating temp and open this valve to bleed off the air. do this with any other bleed screw. over an over again.
1998 Grand Am thermostat?
follow the upper radiator hose to the engine, you hit the thermostat housing and the thermostat is undernieth that
My sister has one! But I don't know where it is, although like any kind of car, look for the radiator (if you have to ask us where that is, go get a bicycle) follow the hose that leaves the top of it, mostly to the right, and you'll see it, it wil before it disapears in side engine, now if it isnt over there, go to left side. Good Luck

What would be the reason why a car is overheating?

okay it's a 93 isuzu rodeo and we've put an electric fan on it and replaced the thermostat and changed a couple of hoses that were leaking and it's still overheating what else could be the problem??
What would be the reason why a car is overheating?
this may b due 2 d radiator problem............ check whether any leakage is there in d radiator......... or else any other fault in it...... try this........
What would be the reason why a car is overheating?
Your best bet is take it to the mechanic to be honest! It definately something to do with the radiator. It obviously not being cooled enough before it over heats. You should check for fluid leaking from the radiator. You mite jus have to get a new radiator and if its a 93 depending on the condition of it you might as well just get a newer one. Hope it works out for you.
if you have anti freeze/coolant in your radiator, while the car is running put your hand under the tailpipe (exhaust) (dont touch the pipe, it will burn you ) just for a few seconds,

if your hand smells sweet like the smell of antifreeze/coolant , its a good chance your head gasket is a gonner. another telltale sign is if you got steam coming out of your tailpipe all the time. also if you should happen to flush your radiator out and get oil mixed in with the coolant or water, that is a good indicator that your head gasket took a dump.
The cooling system is meant to be a sealed system under pressure. Each pound of pressure raises the boilling point by something like 5 degrees so if their are any leeks in the system that allow the pressure to escape that will lower the temp at which your car will over heat. Try replacing the rad cap. To test head gasket most garages have a kit they use to test for exhaust gases in the coolant but sometimes if it is bad enough you can tell by simply looking at the coolant in the radiator while the car is running. If it looks foamy after the t stat has opened chances are bad gasket. Other possibilities are poor coolant flow or air trapped in the system.
Yeah its something to with the radiator has to be,might need a new one,make sure there oil and water in it aswell,not good when a when it doing dont drive it get it checked out asap.
Sounds like a head gasket blown....you may want to have a block test done.
your radiator could be plugged but if i was you i would go to a part store or a junk yard and get a new radiator and then strip the copper out of the old one scrap it and make half or all your money back
Sounds like a Blown Head Gasket; With the System Cool Remove the Radiator cap, Start the Engine and after a short while you will Smell Exhaust in the Radiator, Sometimes Water in the Oil or Steam from the Tail Pip. Are you running Water or Coolant? Coolant=50-50 Mixture of Clean Water %26amp; Anti-Freeze %26quot;Used All Year Round!%26quot; Also sounds like you need a New Radiator cap %26amp; Cooling System Boiled/Flushed Out.
could be head gasket

Can needing an oil change overheat your car?

ive had problems with my car overheating before and i had it worked on my thermostat has been replaced and there is no leak.
Can needing an oil change overheat your car?
if you have little or no oil in the engine, it will cause large amounts of friction which translates into heat. running a car like this is very dangerous as you will likely destroy the engine. so to answer your question, yes, it can.
Can needing an oil change overheat your car?
no.unless your only running 1 quart of oil but i doubt that.
As long as the level is full, needing an oil change won't cause an overheating concern.

If left unchecked, eventually it can cause a lot of other concerns though.

  • My car blew warm air after the indicator jump to red zone, then I took it to the repair shop, they?

    changed the thermostat , as soon as next day, my air conditioner blew warm air when I want cold air, then I added in 1 can 14 oz.ez freeze R_134a but still blow warm air as before, should I tried to add in 1 more can before I take it to the repair shop, because, under the hood the indicator show it need 2.5 lb, but they doesn't it get a bit cooler then before, I use the soap and water to check if there is any leakage, but doesn't look like there is any leakage at all. Please help.

    sounds like you had several issues is the clutch engaging ? on the a/c compressor ? are the a/c fans comming on ?

    A quick way to look for leaks is with a black light the leak will glow bright green. I suspect you have a seized clutch however.

    Help! My car keeps overheating and I can't find the problem.?

    I have 1998 Honda Civic DX 2DR 4 cylinder.

    I recently changed three of my sensors. 1. In the thermostat housing. 2. and 3. The two underneath the distributor cap. The gage sensor, and i believe it's called the Cooling Fan Switch.

    Before i've changed them, i put a switch in my car, so when i turn on the ignition, the fan automatically runs. I wanted to finally fix it, cause i figured the motor will be wearing out. So today after i've changed three of the sensors, and installed a new thermostat. It automatically shoots up saying my car is overheating. I thought it could be electrical, something with my PCM and fuses, but i checked my fuse box inside the hood and everything works. I checked the fuse panel under my steering wheel, and i'm pretty sure everything works, due to the fact my turn signals, horn, dashboard etc. works. I have no idea why it keeps overheating, I put coolant in my water reservoir and also radiator before i turned on the car to see if my fan works. I started the car without the switch on. My fan never went on, after changing three of my sensors and changing the cooling fan relay. I put the switch back in and while driving my car for work, all the coolant that i have had in my water reservoir was sucked up and gone. I put water in the water reservoir about and hour and half later, gone. I let my car cool down and left it alone for about 2-3 hours. I then put coolant in my water reservoir this time, and driving home, (5 min drive) the temperature gage on my dashboard was saying its hot not even driving it for 3 minutes, it usually takes my car about 7-10 minutes maybe a little less to get to where the temperature gage should be. While driving the car home, remember a 5 minute drive, the water reservoir start heating up and steam was exiting out of the reservoir. Keep in mind that i also put the switch back in and the fan was running the whole time. I have no idea why after changing the three sensors and installing a new thermostat my cars tells me its overheating. I hope what i just wrote down can be helpful whoever decides to answer this question, and give feedback. any help is much appreciated.
    Help! My car keeps overheating and I can't find the problem.?
    The first thing to check is the water pump. Is it working? When the car decides its hotter than the thermostat (I believe yours is a 190* thermostat) it opens up and starts circulating water. If the water pump is bad the upper hose will be real hot and the lower hose will still be cool. Reach down there and check it with your hand, is it hotter than the upper hose? If so waters not circulating. Another thing with those engines is sometimes you are filling the radiator and the water is not getting inside the engine, then it just kinda vacuum locks and it never gets to cool the engine. But from what I read of your novel you wrote up there I doubt that's whats happening. If your over heating first check to make sure you have coolant, next do the hose check to see if your getting circulation, the cold lower hose can also be a result of a plugged radiator. Next check the thermostat. I like to remove the thermostat and run the car with out it when I suspect its the problem, if it is the car will be fine with it removed. Then just replace it with a new one. With the engine running squish the upper hose to restrict it. If you feel the water/coolant rush fast as soon as you let go then you know the pump is working. At that point you will need to look at the radiator. Looks like I ended up writing an answer almost as long as your question...

    air block.cracked head, head gasket, could leave the thermostat out and see wat happens.
    Let me be honest.

    I didn't read that saga you call a question.

    But I'm a take a shot that it's a lemon.
    OK, well ,, what ya need there is a new fan on the radiator , A completely new fan assembly . you can check the fan by jumping the wires to see if the fans working ,, If it's not , replace it ,, if it is , then run a wire to the fan from the fuse box, then back to a switch that you will install on or under the dash . Just remember to turn on the switch everytime you start the car , Or run it the hot wire to the fan from the ignition side of the fuse box , that way you will get power to the fan when ever you start the engine If it's not really over heating ,, then ya might have to go into the computr and reset the notifiers , the sensor codes are still reading it because they werent reset .. This might help ya ,, without seeing and looking for ones self , It's hard , but since you went the whole route try that one ... Auto zone can tell ya how to reset the codes , .. C~~YA !!!
    Sounds like Head Gasket, now for what this little thing is it is a major job. 10p worth of equipment but half engine has to come out to get to it. Looking at approx 拢200 all up - sorry :)

    Ask garage if they takle Paypal as a company I called about a briefcase didn't advertise it but they happy to send me invoice -m you won't know til you ask
    If there's no obvious signs of a water leak, i.e. a puddle under the car then the only other cause is a head gasket problem. Check the underside of the oil filler cap and if there is a creamy emulsion on it then its a dead giveaway.
    well you seem to have a leak some where if you keep putting water in it maybe a head gasket or the return hose on the bottom of the radiator or a crack in the radiator you need to find the leak first if you can't see water spill out any where try and put your hand buy the tail pipe and see if you get water on your hand when the car is running if you have water on your hand smell it and if its anti freeze then you have a bigger promblem than that but yea find that leak first
