Its not the oil sensor sending unit. More than likely its a bad connection at the temperature sending unit. I have a 95 wrangler that was reading 260 degrees. I had a couple bare wires touching at the temp sending unit. Fixed the wires and all better now. Otherwise its probably the gauge itself.
My 2000 would overheat at idle; in park & slow traffic. Ran normal on the highway. I 1st replaced the fan relay everyone has been blogging about, engine still overheated. Next attempt for victory, I replaced the temp sensor switch; defeated again. I then replaced the thermostat & haven't had a overheating incident since.
No, not if it was done correctly and the engine has not overheated. Overheating is the main cause of a blown head gasket.
Is you Geo Tracker overheating or the temperature is running almost hot then you need to change you thermostat
The Jeep Wrangler replaced the CJ5 in 1987.
Why dose my 232i overheating
Only when it fails.
Defective radiator cap?Fan temperature sensor defective?
did you replace radiator hoses i have seen hoses collapse and cause overheating while driving and radiator could be clogged. also did you bleed your cooling system according to owners manual
are the cooling fans coming on
have the head gasket replaced
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
Is your fan coming on?
