Hi everyone. As stated I have a 91 sport 5.0. The car has overheating issues. I took it in to get the ac serviced. We were finding out thag the compressor was shutting off because the car was running warm. Changed the thermostat, waterpump, and flushed the radiator as it wasn't leaking so im assuming its good. But even still then it was still running warn. So we went all the way and changed the head gaskets. Still running warm and shutting off the ac compressor. My mechanic looked at the pulleys and found it underdrive pulleys. He thinks that is the culprit but I dont think so. Cause I have underdrives on my fox and it never overheats. It has low miles for 91 only 110k. But with even that im thinking the clutch fan is giving out which is the only thing I can think of. If this is the case tben im taking it off and going to an electric setup. Im getting aggrivated because I just got the car. Thank in advance for any Input.
