Hey, looking for a replacement serpentine belt for my wife's 2001 Silverado pickup 1500, but your site is telling me that there is a difference in belts between a 105 amp alternator and a 130 amp alternator. How do I tell the difference?

Hello,
Unfortunately, I do no know exactly how ascertain which alternator you have. The belt specifications displayed on the "info" pages may be of some help to you though.
Thanks!

Look for these codes in your glove box Rich:

Alternator RPO Codes:
For.....105 Amp Alt.....8W5 / K61 / K62 / K68......(Any of those codes means that you have a 105 Amp Alt)

For.....130 Amp Alt.....8A7 / KG8.........(Any of those codes means that you have a 130 Amp Alt)

Hey! Great! Thanks for the help!

I'm guessing it is probably the 105 amp, as the truck doesn't have anything special that would be drawing a lot of extra current from the electrical system. But you just never know....

I'll have to run over to the garage and see if I see anything in the glove box. Connie's truck has around 120K miles (I think) on it and probably has the original belts on it. We bought it used so they are likely originals.
 
I checked the codes in Connie's truck and it's a 105 amp alternator. I took a look at the serpentine belt that it is in there now, and it looks fine to me. No cracks or anything looking like the belt is passed it's prime. Looks like it will be a pain in the butt to change out, too. I think the air intake will have to come off to get to the tensioner. So maybe I don't need to be in any hurry to change out that belt. :)
 
I can't remember when I last had to change one from it simply being worn or cracked. But I always keep one behind the seat of my trucks just in case. And I have been glad I did twice. When I was driving my last one ton dually commercially I had a water pump bearing go bad and chew one up in Indiana and another time the vacuum pump locked up and ate it in Tennessee. Both times I had to be towed but at least I had the right belt. It may not seem like much savings but IIRC I paid over $500.00 for each repair. And if I didn't already have a belt they probably would have charged me another $100.00 or so. They gouge you pretty hard when you're on the road and have break downs. I'm just glad I didn't have an RV on the back of my truck when it happened or the tow bill would have been double.
 
Yeah, I have a spare belt in the trunk for the C5Z, but haven't gotten one for the C6Z nor the Jeep. Might have to do that, as it really is a good idea to have spares handy.
