Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello my name is Bob.
Does it only do it with A/C on?
Have you tried to clean the outside of the radiator and A/C condenser fins? I have had luck just using a garden hose.
Do you have a scan tool? If so see if the temp sensor reading is the same as the gauge.
Please get back with me
