I have been trying to ruin down that belt or pulley noise for weeks. I do not want something to fail and go through my new radiator. At first I thought it was the AC clutch bearing. New bearing. Then perhaps the idle pulley bearing. I got an NOS one and it sounds worse! I studied the pulley bracket very intently and it is perhaps a hair bent. So I pulled it off again and ran a straight edge on the bracket and the pulley face it appears a little out. So I give it a whack and put it back on and the noise
goes down a lot. As I am revving it HARD I also notice that the alternator-AC belts look like they want to “climb” a little on a hard rev. That bracket is forged so I do not know how that can be adjusted if it is out a little. In the AM I am going to pull the idle pulley out one more time and give it a little more in the same direction and see what I get. I wonder if these new cog style belts bite better and if things are even a little bit out of alignment can cause the belts to squeal under a load more than the old smooth belts? I did spray them with belt dressing. What a PITA.
