Ive recently put on Agency Power Under Drive Pulleys. Now when I use my A/C the belt squeals. Do I need to tighten the belt?? I thought it was pretty tight myself. Im always a DIY I don't believe in doing it any other way. I like to learn. So help me out please.

 

Too tight and it will make it squeal too. If you have it on real tight then loosen it a bit.

 

Thank you

 

Did it work?

 

Otherwise take the belt off and make sure the magnetic clutch on the A/C compressor isn't locked up.

You can also look at it with the car running. The entire clutch/pulley/etc spins with the A/C on, and should free spin with it off - the clutch will remain stationary.
