<VV> Squealing noise from engine compartment

[Mark Durham]

I had that happen, used some belt dressing which allowed the slippage
without the noise. I used s silicone spray, however I have seen a waxy
looking stick you rub on the belt, too with the engine running. Of
course, you may have a bad bearing as others have said. Mark Durham

Slipping belt?  My Fiero has the same symptoms except it does quit
after it warms up or when you have a new really tight belt.  The
alternator doesn't work until the squeal stops - that's how I know the
belt is slipping.
