You got the right compressor? No reason it should not be a perfect fit. Got a pick you can post?

the belt is sliding over coming over the backside of the harmonic balancer for some reason.

Where did you get the compressor from? Is it a GM unit?

looks like it may be the belt itself. looks like one of the grooves on it came off. so when i flipped it around it isnt coming off. looks like im off to the parts store damn i feel like a dumbass. belt looked good other than that :censored:

It could be a problem like I had... My AC compressor pulley was about a half inch behind the harmonic balancer pulley.... My belts kept striping off on the inside...

Look the same?

I ended up replacing the harmonic balancer, and I haven't had any problems since.

mine was just barely riding on the outside of the harmonic balancer, went and got a new belt. so far so good guess i'll have to keep an eye and ear on it

If it tears the belt again, you'll probably want a new balancer. I went through 3 belts already this year. :lol:

Are you sure it's not the A/C compressor? Considering the source it would still be my #1 pick as the problem.
