Engine Mechanical problem
2002 Chevy Venture 6 cyl Front Wheel Drive Automatic
my serpentine belt on my 3.4 liter Chevy Venture rubs slightly against the back of the belt tensioner. Both belt and tensioner are new. It rubbed worse on the old one, but the new one has a larger dia. Pulley, by about an 1/8 of an inch. It seems that the belt should be slightly bigger, or the pulley on the alternator should be smaller. Both the belt and tensioner are to factory specs (checked twice). Do you think that as the new belt wears in, and streches a bit, that the problem will rectify it's self? Or should I try a longer belt, or new alt. Any sugestions would be greatly appreciated. Thanks!
