I called the parts store today to get prices for a
new serpentine belt and got more questions than
answers . They told me to find out what size
alternator , do you have a vacum pump and how
many grooves in the belt. I have a 2002 GMC and
don't have anything special from the factory . How
do I find out what one I need ?:)

97300653

Can be found @:
CSK (Checker, Schucks, Kragen)
Dayco Belts 5061115 - Premium

or as dmaxalliTech put it for GM
97300653

Thank You for the belt info .):h
