Cracked.head
Thermostat and radiator
That depends on the thermostat. If it's a 185 thermostat, the engine should run at 185. If it's running too hot, check the thermostat, radiator and water pump. If it's running too cold, replace the thermostat.
Could be a bad water pump.
If water is coming out around the thermostat housing, the seal or gasket is bad.
Thermostat sticking. Replace thermostat and gasket.
It's likely the thermostat. That's assuming the coolant is full. Thermostat runs $11 for the 3.5.
Is you Geo Tracker overheating or the temperature is running almost hot then you need to change you thermostat
This is likely a stuck thermostat.
Low coolant? Thermostat not opening?
Running a vehicle without a thermostat will cause it to take longer to warm up and your interior heater may not blow hot air.
Thermostat is stuck.. Is the cooling fans coming on at 232 degrees? Is the radiator sludged up?
