Is you Geo Tracker overheating or the temperature is running almost hot then you need to change you thermostat
it goes out and your heat will be gon
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
Well, I know when a tire on my car needs to be replaced when there is no tread left on it. What are YOU referring to
it should be replaced when it stops doing its job controlling the temperature and replacing the battery does not solve the problem or it is showing a digital error code that tells you it is defective. You may also want to test if it actually is doing its job but the heating or cooling unit may be broken. If you have more than one zone and you know what you are doing, you can switch it with a known working thermostat and see if the problem stays with the zone or it moves with the thermostat. That should tell you if the thermostat is broken or the system related to that zone needs maintenance.
Overheating or no heat from the heater are sure signs it is bad. You car is 12 years old, just replace it if you have a suspicion it is bad. You can test the thermostat but why bother? You will have to remove it to perform the test. Just replace it.
Usually it means that the oil needs to be changed, or that a belt of oxygen pump needs to be replaced. If it's letting you know it's detecting something, that means that it's not that bad, but needs to get fixed.
ask yourself this question is your tracker over heating? if you said yes you may need water pump, thermostat, and engine coolant :)
Two symptoms of faulty thermostat which would more than likely require replacement of same: (1) engine overheats quickly (2) engine takes too long or doesn't reach normal operating temperature
Would need to know if car was overheating before waterpump and thermostat was replaced.
When the engine overheats because thermostat won't open to allow the water to flow and cool!
If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing. As the water pump should be replaced at the same time as the cam belt every 90,000 miles, you should also replace the thermostat and coolant.If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing.

If your engine takes a much longer time for the thermostat heat guage to reach its required level of operatiing temperature then the thermostat may be stuck in the open position which means that it will need to be replaced.
