I just fixed my ac leak and charged up the system. Once the compressor kicked in I could hear a very loud squeal kind of like a belt. I replaced the idler pulley and tightened the belt well.
The sound was still there. Upon a close look I found that the squeal is coming directly from the ac compressor clutch. I could ony hear the squeal if I have the ac on.
The clutch (triangle) is really hard to turn by hand and gets stuck quite often.
Could this be fixed or will a new compressor be necessary?
Also if I do need to buy a new compressor will I need to recharge my system with r134a?
