Why do I have a Engine hot A/C off message

Asked by Rhonda Aug 14, 2023 at 07:50 PM about the 2008 Chevrolet Impala LS FWD

Question type: Maintenance & Repair

The car is not indicating the car is running hot. , and quick
lube advised the car almost had no oil.  They said there was
oil at the bottom of the car on places the oil could actually
leak onto and suggested I bring it back for a diagnostics
check to see if it was a coolant or transmission oil leak.  
Please advise so that I don't waste money.

Well your first mistake was going to a quick lube place. You need to have a reputable shop look at it. Sounds like the coolant temperature sensor is unplugged or has failed. When the computer loses the signal from the coolant temperature sensor it assumes the engine is overheating. To try and prevent serious damage to the engine the air conditioning is disabled and the radiator cooling fans come on at high speed. Hope that helps! Jim
