2005 Yukon Serpentine

[WEFs99]

100k miles so I'm going to replace the belts. It's the 5.3 FI K1500 and all the places I go for the belts ask if it is a 105 amp or 145 amp alternator. Mine, for some reason, is a KW1 160 amp and no one, so far, can find a listing. As a last resort, I can pull the old belt off and buy it locally but I'd rather buy it online. Anyone run into this before?

The 145 amp and the 160 amp are the same belt,GM part#12637204 (2365mm)

BTW...For reference,the 105 amp belt is GM part#12637202 (2345mm)

Much thanks!! Would you have any idea why it would have that big of an alternator? It has the towing package but nothing else outstanding.

Maybe it was ordered that way and the person that ordered he vehicle decided not to buy it.

I need to see if that 160 amp will retro fit on my 02.........

you could have always told them in was a 05 Escalade with a 160 amp.....

 

eta:

the parts guys used to pull their hair out when my buddy and I went to get parts for his:

2000 model Chevy Silverado, 1/2 ton 4X4 with a 6.0L (motor swap truck, that year did not have a 6.0L available in the 1/2 ton).... it uses all the same parts as a 4.8L or 5.3L so it really doesn't matter, but it was funny to see the look of confusion on their faces.
