Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Is the engine overheating? Do you have a kitchen thermometer? If so, place it into the radiator fill hole and take a reading there after the thermostat opens. If it is alot different from the dash, the the problem has got to be with the sender, gauge or wiring if not then the engine is overheating.
Let me know which it is.
do u think a 180 thermostat will make a difference
I just recently purchased a 2004 Tahoe with 155000 miles
