Thread: Supercharger whistling ALOT

So I was driving the Grand Prix on the highway and decided to pull off and flip around to go the other way. I slow down and while I idle the car has some noises coming from the belt area so I figure its just a sign the belts are going bad (they are glazing over). Then as I start to take off (I do it very slowly) the supercharger starts to whistle on me and just gets more and more profound until I start giving it more gas to the point where the supercharger kicks in and you can hear it real good. So I just dont know what happened but it just starts to whistle anytime you give it gas. So what sounds like the problem?

Alright thanks for the help. I will do that tomorrow when it aint so cold and dark out!

Will do!

Do you have a picture of said vac line? I don't have a belt puller to remove the belt and I am not seeing any that have fallen off.

Sadly I don't have any metric sized wrenches, just American. lol

I sure hope so I have tons of those

Disposable income? I has none. lol

Ok I got the belt off and spun the supercharger and I heard nothing from it.....now what? Did I not spin it fast enough? I turned it as fast as I could by hand. Should I borrow a friends torque wrench and run it on there?

Damn just got off work and saw this. Looks like I found what I am doing tomorrow morning. lol

Alright well I found the issue. I could tell you straight up but I would rather tell the whole story lol.

Anyway I walk out of work tonight and hop in my car like any other day. I start it waiting for it to start whistling and even more recently shreaking at me, when it instead just sounds normal like it would on any other day. So I sit there just laughing to myself when I hear ,squeak squeak squeak coming from the engine. So I immediately know that the belt on the supercharger is in fact in need of replacement, so I pop the hood. Take a look at the belts using my cellphone and can hear the belt squeaking from the tensioner. So I shut the hood, hop back in, and head home. As I pull in my neighborhood the squeaking had subsided so I give it a little gas and then a rattling (more of a bells jingling sound) comes from the hood. So I got home, pop the hood, and pull out my trusty phone and see the belt had slid off at the tensioner (awesome). So checking the belt it has just a little wear on the edge facing the passenger side of the vehicle. So I was thinking I should just remove the belt and then pick up a new one tomorrow and install it. Its safe to drive without the supercharger belt, right?

yes it is.
