ISO 1955 12v Alternator pulley

[Ed R]

Hi All, I had AC installed with a 12v Alternator. The pulley for the Alternator is not a V groove style like the rest of the system and the belt screams when the AV is engaged.

So, I want to replace it with a deep V pulley. Anybody know a vendor that would have it?

It has a GM style one wire alternator, if that is significant.

Thanks in advance Ed R

There are several widths of "fan belts". 1/2" and 5/8" are pretty common. Find out what width your belt is and then look for that pulley set up for that width belt. You can find some on Amazon if you search "GM alternator pulley".
