supercharger making loud noises at idle!

Ok guys how hard is it to take of the blower? AT idle the eaton is really loud and noisy and its getting annoying. Someone on the srtforums told me that hes pretty sure that i have a bad coupler and i think he might be right. I pop the hood and watch the belt spin and the the tensior and the belt on the s/c looks loose as ****. Is the bad cupler my issue as o dont want to get a new blower as i found a deal on another one if i have to.

You just have to remove the belt and 4 bolts for the SC....

Are you serious?

The coupler is inside the supercharger, It transfers motion from the shaft to the rotors... Please refrain from giving advice if youre not entirely sure what your talking about.

Also, what type of noise is it?

Squeaking or like marbles in a can type of thing?

Yes, the coupler is in the SC and does make noise if going bad or is bad.

You mention that belt, lol. Hearing of the belt issue scared me so much that I got the pulley boys tension relief tool and the LSJ engine lift bracket (for the tension relief tool to work) so that should be a snap now!

i had the same problem and it was my belt tensioner. The tensioner is the shock like object that keeps the belt tight, if you can wiggle it its bad.

Im pretty sure the parts are reasonably cheap if you do it yourself. If you pay someone to do it, im sure you will pay out the ass for it.

Is it bad if I do not fix this problem? I bought my 06 cobalt ss/sc used from carmax w/ there warranty. I will check to see if its covered then I will have it repaired, if not then I will jus wait it out until I get more cash. I am a colleg student & I do not have much time to really get involved in my cobalt like I really want. Plus I want to get a new head unit from pioneer before I start changing anything under the hood. I appreciate the help.

Okay, so you know something is broken, but you are wondering if its bad if you dont fix it?

Use some common sense man.

You can end up needing to spend hundreds on a new supercharger....

okay the supercharger apart is dumb easy. Its a few bolts and thats basically it. The rotors int he casing have a roller bearing design in the back and the front where the coupler meshes with the rotor gears has bearings. You would be suprised what the coupler will do when it looks good but is not. But take the rotors out look at them for contact check the casing for contact if either exist wither brearings are bad or the supercharger its self may be bad depending on the extent of the damage. My advise either pull it apart and inspect it or run it till it blows and put a turbo on it.
