I have a slight problem....
Whenever I turn on my air conditioner, my truck (1988 C1500 5.7) starts to overheat slowly. After I turn it off, it cools down, but slowly. Can this be a sign of early compressor failure, or is it just the air condition compressor clutch, or do I need oil in the cooling system. I hear a low knocking sound coming from the compressor, but I am not sure if that is a problem. I took off the drive belt and engaged the clutch and found that the compressor was kinda hard to turn with it engaged. Can I solve this problem by just replacing the clutch?, I dont wanna evacuate the refrigerant. My guess is that when engaged the compressor slows the drive belt and slows the waterpump. Not sure if tis is right. Thanks...

No your engine has to work harder to maintain the same RPM's. The belt speed is directly proportional to engine speed. As far as the A/C system, I don't know much about that, I never used mine,R12 makes me sneez continuosly until turned off.
