Belt squeal after pulley change M113K

[SL03WLY]

So, today’s the day the aux belt shred itself. Took the supercharger belt off too.

Does someone know the common reasons a belt would shred?

Check free movement of water pump, and also alternator power steering pump with belt off most liklely one of them is the culprit! good luck dave

Replace the belt and the tensioner

Any chance of a picture of the break, may yield a clue? I still think there is a pully out of alignment though. Grab a straight edge and lay it across the front of pairs of pulleys and see if it lays flat, if you have access to a laser level or pointer then use that to project a line across all of their front edges at once. At least that will eliminate a common cause.
