How did you make sure?

Did you take the s/c apart and see for yourself?

The tensioner pulley is easy, just requires some man-strength. *cough* 20-30 bucks. The M90 is serviceable, it's just that the bearings are something of a pain in the ass to repair, and most people will just say f* it and replace the whole snout.

I honestly would start small and just replace the s/c coupler with the one from ZZP. If it still makes the noise after that, then it's the bearings, and you have a good s/c coupler that won't soon wear out like the GM one. If the noise goes away, you just saved 300 dollars.

Herc made a good point, you stood against them on the 1500 BS and they backed down and said it was something else, still expensive.

Odd, no?

Well, in conclusion, you can change the pulley yourself, and if you want to throw away your money without seeing for yourself what the real problem is, that's your choice, but if they're lying and you get screwed, remember that it was your choice.

can somebody explain what the coupler is??i promise im not a airhead but really when it comes to superchargers i know ZERO......all i know is there is rattling and grinding...they said the pully would take care of most of the sound but heck that alone would cost me 150.00 there are no other symptoms with my car only noise

A pulley should not cost 150 bucks. Seriously. Talk about price-gouging. I think the tensioner pulley would squeal more than it would grind, anyway? I know my idler pulley did, I wouldn't think it would be much different.

Let me see if I can find the FAQ for a coupler fix.

Edit: Found it. http://www3.sympatico.ca/aepa/blowerinstall.html

no i didnt take it apart i asked them like 3 times if they was sure if thats what it was..this isnt the dealership i bought it from the used car manager took it to a different shop this guys has a car with a supercharger in it he said and has 32 years experience behind him BUT i know how these places work and i already got ripped off from a different shop on a different car where they said they rebuilt my transmission and come to find out they only replaced seals and took 1300.00 from me

Lemme see if I can find some pics...

Maybe I'll draw one.

That's the install guide, pics and all.

Couldn't show it better myself.

Agree with Herc..it's the coupler, and the tensioner pulley isn't hard to replace either. I left the coupler write up link for you on the first page of this thread..

Here ya go: Replace Coupler

hmmmm ok this is sooo messed up i mean seriously to go through all this bs to get a car fixed the warranty obviously was the joke on me thankyou all for helping

Just don't want to see you get gouged by the $tealer$hip for a relatively inexpensive fix..
Our shop would do warranty work all the time, because our customers didn't want to pay the higher labor rates at the dealer. Makes me wonder if the previous owner traded this car in because of this..

yeah and to be honest either way i probably will get screwed because i will have to take it somewhere i have no tools and wouldnt know where to start but may try anyway...lol my dad did all this for me but hes dead now must do it myself darn it

Try Ohio ClubGP.

I bet Greenie or someone wouldn't mind helping you.

maybe you should invest in a small tool set?

It's really going to be needlessly expensive to have ANY car place replace that coupler, in fact, I don't think many places will.

A REALLY basic tool set would suffice for this project.

Plus, it's something you could keep in the trunk for emergencies or even at the house for household repairs.

very true!!im going to try my boyfriend will help and he has tools

Here's the coupler and the GM S/C Oil (You'll need two bottles)

anyone with any real mechanical skill at all can do a coupler replacement. your boyfriend shouldnt have any problems.

This is also a perfect opportunity to get to know your fellow ohio GP owners
