Has anybody changed the ideler pulley before? How hard is it to change?

 

The pulley itself, very simple. It uses a torx bit, think 45 or so. Watch your knuckles though...if it slips off, your knuckles are toast.
Using the idler pulley bolt is actually another way to relieve tension on the belt. I've had to use it on more than one install.

 

awesome, do you know how much that pulley will run me? Where would I be able to buy this at?

 

the stock idler pulley..??

 

I am putting a 2.8 and I seen the Rebel stage 1 kit has a larger one. So I was thinking a larger one if its not needed I would put a stock one.

 

here....if you want a 76mm idler pulley, don't go to one of the various forum vendors....they are charging way too much.
The maker is Gates Corporation and the part number is 38009. Just search pulley 38009 on google and you'll see it cost $12 from rockauto.com
Its a 76mm drivealignŽ groove pulley part number 38009

 

so thats the pulley that goes on top of the tensioner and the stock size? It has the grooves and everything in it? Thanks for all the help

 

thats a bigger pulley, perfect fit when using a 2.8 and smaller belt.

 

there is no modification needed to install this? Do you know where I could order the stock size as well?

 

No modification needed, well..a smaller belt (stage 2 belt #12597993).
You can get it from a GM dealer...give me a few days and I can get a part number. Or you can go and request the part number yourself.

 

alright thanks a lot. I was just thinking that with the stage 2 belt and the bigger idler pulley that it would be too tight. I will go to the dealership tomorrow and see if they can get me a part number.

 

it will be tight, but perfect

 

Whats the size of the stock one? Does anybody know? I need to order one of these as soon as possible.

bump somone must know this. I dont want to pay 400 bucks for the whole setup.

 

chad I have a used stock one with around 5k on it. Pay the shipping and its yours.

 

sounds good, how much is the shipping?

 

I want to know too please!
I don't need the Pulley,

But I baught my car used, with a 2.85" SC Pulley, and I know
the belt won't last forever. I need to know if I have an oversized pulley
or an undersized belt.
