Hey everyone, lately I have been having some problems with my Dayco belt and I think it's time to upgrade. Anyway, I was looking on Amazon and two Gatorback Belts came up as compatible. I am not sure which one I should get.. They look the same to me except they have different model numbers and one is cheaper than the other. Can someone help me out?

Amazon.com: Goodyear 4060872 Gatorback Poly V-Belt: Automotive

and

Amazon.com: Goodyear 4060950 Gatorback Poly V-Belt: Automotive

Note:

I have a 2000 Blazer LS

Thanks in advance.

 

one is for a/c other is w/o ac
But there's another consideration

Which of these two ac clutches do you have?


The 4060950 fits the smaller of those two. You want the next size up 4060952 if you have the larger {which came on my 99}

Also kindly put your comments on this thread which is about our problems with Dayco

And BTW... There's a Dayco on my Tbird. It doesnt make noise {prob because the tensioner is MUCH stronger.. needs a breaker bar} but it has those same deposits on the back of the belt and I can barely make out the brand though the ribs are in great shape.

 

Alright thanks, from what I can tell, I have the larger one - on the bottom. So I guess now the only thing left to do is to purchase the 4060952.
