Hey, I am in need to replace my drive belt for the alternator, and wondering if the belts I broght from Autozone, which have teeths on them work well? Cause my stock ones don't have teeth's, and these do. Or where can I get the stock ones, without the teeths on them at? And how hard is it to replace? they look like their going to be a pain in the *** to replace.

 

just get the Gatorback belts, they are very good

 

I don't think I ever saw any with teeth.. It might work though.. I've always just used a normal, stock-like V-Belt. I get mine at Advanced Auto. The brand i get is (parker) Dayco. I think the alt/water pump belt costs 9.50, in stock.

As for changing them, you're not going to get too much easier than these cars It really is a 10 minute or so job to replace them all, if that...

 

I think that the belts with the teeth, have less contact area.

The belts with teeth have a couple or so advantages. One thing is they grip much better so not as likely to slip and make noise. Another is they dissipate heat a lot better. O'reilly carries the Gated knotched belts or Gates secondary name for O'reilly. A Gates is about $14 and the secondary is about $3. Both are excellent. I hightly recommend the teeth (knotched) belts. They are quiter and smoother operating. However, any belt will work. I just think the knotched is better.
As far as more surface area on the no teeth ones, when the belt bends to make the 180 around the pulley, the teeth fit together closer when the belt bends increasing surface area, then as they straighten up and regap, they cool off some.

 

the one without teeth and a solid piece grips much better....
you dont have to make it as tight to get a great result...

 

Thank you for the valuable info.
I did not know that.

Thanks guys, I think I'll go with the Dayco ones. Can anyone verify if these fit on an S5 N/A? http://www.partsamerica.com/ProductD...ype=12&ptset=A

I'm about to order online, and don't think i can return em if they dont fit right.
