Need a new serpentine belt. Gatorback / Continental part #?

[walther78]

2003 Tahoe Z71 with 5.3l Flex. How do I know what size alternator I have? 105, 130 or 145amp?

It appears Continental took over the Goodyear Gatorback series. Does anyone know the part number I need for the belt?

Thanks!

Or is there a different brand preferred?

I'm no expert, but I understand that Gates is a good brand for belts.

I have always used gates belts and hoses. When at all possible i try to take the old belt to compare to what they say should fit especially if it`s at an auto zone or advance auto. That way you wont be making a second trip to the store.
