1988 Civic DX D15B2 engine. The car's A/C compressor was frozen (would not turn at all), so I evacuated the refrigerant and replaced the compressor with a used unit. After refilling the refrigerant and oil using a low side pressure gauge, the air conditioning was functional for 1-2 days. The belt then started squealing once the compressor was turned on for 1-2 minutes. The belt was adjusted properly. The problem seems to be that the compressor becomes too difficult to turn after operating for a short time. Has anyone experienced this? What might be the problem?

 

i found that it took a new belt to eliminate the squeeling on the AC belt.

i thought it was the tensioner pulley bearing, but a new bearing made no difference even tho it was bad.

 

This is with a new belt.

 

actually, I think its an easy mistake to improperly install the pulley. The washer must go under the thin cover. then you put the nut on. It acts as a spacer, without it or put in the wrong place, the pulley will lock up and fall off.

Consult the shop manual for the right installation.

 

You are referring to the pulley of the A/C compressor and not the tensioner pulley, correct?

 

No, I'm talking of the tensioner pulley.
