2000 lumina ac

Trying to replace pully and clutch on 2000 lumina ac. Any advice?

You need a special too to remove and install the pulley, for one thing.

I have a seal leaking behind my pulley...I checked into it a bit and found a) need a special tool, as Max said, and b) supposedly front clutch/seal repairs on V5 comps are usually unsuccessful...info from my uncle who owns an auto A/C and speedo/gauge shop that's been in the family since 1938, so I tend to believe him....new compressor is gonna be my solution.
