Q: Overheating at idle but blowing cool air. Also when I press the gas it cools it down. What could be the issue?

asked by on June 09, 2017

I've had this car for a few years now. Never had a single issue. Today, it starts overheating. The air got hot and then it got very cool. Also when I'm idle it starts to overheat. But if I press the gas the temp goes alllll the way down. What could be the issue?

My car has 147593 miles.
My car has an automatic transmission.

Hi There, Overheating with the AC on is generally caused by a couple of possibilities. When the AC compressor is beginning to fail, this may incur an increased load on the motor as it works harder than usual to turn a bad compressor. This increased load causes the motor to work harder than it otherwise normally would, resulting in the motor overheating. The other possibility may be a cooling system that is not working efficiently. This may be caused by a clogged radiator, blocked or clogged radiator condenser fins, a water pump that is not pumping correctly or potentially cooling fans that are not working properly.
