1998 Chevy Lumina air conditioner compressor

On newer types, go to the junkyard, because aftermarket bearing and pulley will not fit, unless you swap the coil too, pick out a good used compressor, and if yours still works, just swap the pulley. Wont even need to open the system, usually a 8mm screw holds the clutch face on, then a snapring hold the pulley. Be sure you put the snap ring on facing the same way it came off the old one!
