Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
HelloCustomer my name is Mike.
It sounds like you do need a thermostat. You could also have a bad fan clutch keeping the fan fully engaged at all times. I have included instructions for a thermostat replacement. It is a little tight but I wouldn't rank it as hard just time consuming. Please ask if you have further questions.
Air Cleaner Assembly Replacement Removal Procedure
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Thanks a lot. It worked like a charm. After cursing for a half hour or so trying to get the bolts loosened up, it all went smoothly. New thermostat and the temp went right back up to normal. You may want to recommend having a close quarters ratchet in the future, but thanks for the info.
I'm glad you got it fixed. I wish I would have thought about that close quarters ratchet thing but I usually bust my knuckles and curse with my air ratchet in hand.
Thank you for the accept, bonus and positive feedback. Thank you for using Just Answer and have a good weekend and holliday season.
