Thermostat can stick open or closed. If sticks open, car will take longer to warm up because coolant is constantly flowing thru engine. If thermostat is stuck closed, engine will eventually overheat. In order for all emission systems to work properly, thermostat needs to be working. For 1995 GEO Prizm, if thermostat is working correctly, car should maintain proper operating temperature after is warmed up. If any doubt about thermostat, changev it every few years as is inexpensive and easy to replace.
Is you Geo Tracker overheating or the temperature is running almost hot then you need to change you thermostat
When the engine overheats because thermostat won't open to allow the water to flow and cool!
If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its thermostat
it goes out and your heat will be gon
If the engine is overheating, the thermostat is stuck closed. If the heater is not putting out enough hot air the thermostat is stuck open. Change the thermostat as a normal part of maintenance when changing coolant.
I don't know but I found your question because I need to know the samething!
i had 1991 geo prizm but i want to know what color memory wire??
i don't know, as that car does not exist. prizm went to Chevy in 1998.
Need to know if its a 2.4 L LD9 or a 2.2 L motor
A thermostat can be stuck open or closed. If the engine runs to cool it is stuck open. If the engine is running hot it is stuck closed. If you don't have these problems you should'nt have to change it.
I have a 94 Audi 100s and the thermostat is located behind the timing belt so you should think about changing the timing belt, water pump, and thermostat. I know this is a horrible desighn but what can we do.
if your car over heats alot then that is a pretty good sign. aslong as it isn't your water pump. but thermostat is a good place to start. if you replace the thermostat and it still over heats. (assuming that is why you are asking) then it could be the water pump.
