Not right off hand, we just had a stocker laying around a buddy's shop after he installed a magnacharger on a customer's '10 Camaro SS, which replaced the stock pulley with something else I assume (never looked under the hood to see)

just a fyi for whoever is interested i bought the dayco tensioner this morning and was gonna get the buick pulley right away.....turns out they must know of the issue because the pulley on the new tensioner was the same exact pulley as the buick one. i confirmed this after i got home and saw that the new one is def a little larger than the oem pulley that i took off

I just checked on the price of a 2010 Camaro tensioner and it's $120, so that's a waste considering a Katech is less.

So let me ask this, when you put the pulley on the tensioner, I forget, is there a washer that goes on the back or just the front?

Did this the other day. After my P/S pump & Alt relocation, the serpentine belt was about 1/4- 1/2'' too large. I grabbed two belt sizes down from the stock belt length and both were too small (of course). So dredging though threads I found this. The pulley was just right. Still part number 89009 and made by Dayco. The added bonus is that the pulley has been "altered" since this post. Absolutely no grinding required. Pull the old one off and put the new one on.

Always good to still see people helped by my old posts.

Even better to see that it's someone local to me.

Keeps the belt from flying off as easy. The larger diameter helps and the shoulders are higher
