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. Then add anti-freeze mixture until full.|||Two things, you have installed it the wrong way or it%26#039;s the wrong thermostat.|||it depends on the car.
some cars need the cooling system bled for air that is trapped,,,there is a bleeder valve on the engine,,,,just opening the cap will not do it.|||you may have got a bad thermostat,either that or you could have air in the system try bleeding the system out and see if that helps it ,if not take the thermostat back and get another one,the other day i bought two before i got a good one,you have to remember anything made by a machine can be bad,and its possible you just got a bad one,it happens a lot these days,good luck|||you may have problem wiyh you water pump. this would cause both your problems.
