Goodyear Gatorback Belts Part Numbers

[mattb5150]

Does anyone have the part numbers for a 2003 Duramax with dual alternators and CA emissions, with vacuum pump. Or does anyone know what length this belt would be? All the online catalogs I look at show dual alternator set ups with an 8 rib belt but mine has a 6 rib on it.

What brand is the factory belt for your application? I've had pretty good luck with OEM. :)

mattb5150,
I installed a second Alternator in my truck and when I was doing so I came accross a bulletin with the part numbers. I hope this helps. It was correct for mine without the EGR.

Here's what it said for the 2002-2003 models:

Single 130A, No EGR, belt 97300654, 3012mm
Dual 105A, No EGR, belt 97300655, 3455mm
Single 130A, with EGR, belt 97300656, 3034mm
Dual 105A, with EGR, belt 97300657, 3476mm
