Hey ive been seaching but cant find any real helpful info . Does anyone have any helpful links or pics/info on replacing the factory idler pully with a larger one. Any info would be great thanks.

bump i know im not the only one to put on a larger idler pully

 

I offer larger idler pulleys, originally designed for the Grand Prix L67 but if someone wants to try one out on a Cobalt I'd be interested in offering a deal.

Here's a pic of the set I've made for the supercharger idler set of the L67...

 

****** nice. if they work.. i would love to get one from you. what are you asking?

 

benifits?

 

no belt slippage with smaller pulleys

 

If i were to try a larger pulley, i would no doubt get nates pulley..

Awesome, awesome... awesome...

 

very little... but looks nice.

 

nate makes the best pulleys IMO

how much for just the one idler pulley nate?

 

Go to any aftermarket parts place and get a grand prix GTP idler pulley, they're cheap. Install it and take a good file and while the motor is running file down the inner edge until it stops contacting the arm.

 

Lets see, using a file on the idler of a running engine...just have 911 on speed dial because dialing 3 digits then pressing send may take too long!

For those of you interested, I am willing to do one for the first person interested for half price, 25.00. Normal price is 50.00 for an idler pulley but you get the benefit of it being light weight anodized aluminum, the bearings are replaceable so if something happens you can replace just the bearing, not the whole pulley, and of course they look amazing! The test fit may require the pulley to be shipped back to me to do some more machining if it rubs. Another option is you can grind down the arm where it rubs which would probably be easier.

Is anyone interested in testing a larger billet aluminum idler pulley?

 

yes. what isyour paypal. will send money asap

 

yes I woul let me know how to get a hold of you for payment.

 

money sent... will test asap

 

anyone able to tell me how to get these on and off? I am trying to help a friend install a larger pulley... but we cant seem to get the oem one off.. and dont want to bust anything....

 

from redline forums i found this

 

SWEET that is alot easier than i expected. and good to know about the possible rubbing.
I cant wait to tell my friend that i figured it out! wait.. hang on i will tell him right now!!!

JOSH!!! guess what... i figured it out... we just pop that plastic cap right off and the bolt is behind it!!! some dufus on cobaltss.net posted up this neat lil animation of how to do it. You got a grinder at home? or you want to bring the car out here and we can do it up?

 

you do nice work Mr.Nate.....

 

haha thanks man so what your saying is that all i have to do is pop that plastic cap off and loosen that bolt. LOL I didn't know that was you haha.

 

I can vouch for that... I have a pulley of nates on my other car, and it is top notch!
