Hello, my name is Bobby. Thank you for the question. Does this ever happen when the a/c is off?
Customer: replied 2 years ago.
AT first i thought it was only running hot when the AC is on but now it is running hot either way. Only while sitting at a red light.
Expert:  FIXITMAN replied 2 years ago.
Okay. Just so I am sure it does not do it when the vehicle is moving?
Customer: replied 2 years ago.
That's Correct
Expert:  FIXITMAN replied 2 years ago.
Thank you. With the engine running turn on the a/c and see if the fans on the radiator turn on. It sounds like they are not. If not then that is the problem. At that point we would need to test the circuit to see what the failure is. Did you plan on fixing this yourself?
