How about the idler and/or tensioner pulley. When the bearing inside is
going or goes out it can cause all kinds of problems. You should be able to
take the tension off of the belt and see if they have any play or make any
noise. Just an idea, John.

Subject: DML: Bad serpentine belt?
.My '99 V-6 with 33,000 miles started sounding pretty bad when it starts up
cold. In neutral it sounds ok, but when put in drive or reverse it sounds
like groaning and grinding. I thought it might be the transmission, but
yesterday I checked and the noise is coming from the belt-fan area. The fan
seems to be ok. The belt runs smooth in neutral, but when the truck is
shifted into gear the belt starts to vibrate like it's very loose and the
noise starts. When the truck gets warmed up the noise goes away. Does this
sound like a bad belt to y'all? Visually the belt is in good shape and it
seems tight enough until we've shifted.
Thanks,
Cal
