Hi, I have an 04 Copper S in which the supercharger started making a loud whining noise every time u touched the accelerator. It is not the usual spinning noise of the SC which in familiar with, is a different louder spinning noise like. So I read a few threads and learned that SC tend to fail around 110k to 130k which is around what my car has right now. I have pulled the SC out following a forum DYI and I was planning to change the oil hoping that maybe it was just low in oil, but now that is out I'm wondering if there is anything else I could do to confirm if the SC is indeed bad and not just low in oil. I wouldn't wanna have to remove this thing again since is a time consuming job. Any help will be greatly appreciated. Thank you. Ed


Dupplicate thread...sorry, how do I delete it ???

 

You try checking the belt?
Other than that....when the sc goes bad...time to swap it.
If the oil is low...from presumably a bad seal...doing 8 hours of labour to remove it...fit it, replace it is a waste as it will go low again....and you need about $50-65 is new gaskets to do it...

 

Belt is good. Makes sense, but I can't afford to replace the whole SC right now so I guess I have to extend it for a little n duplicate labor 😣

 

There is an idler pulley that is part of the sc system. When you change the belt, change that pulley as well. Will cost you a few extra bucks on the front end, but will help the system last longer. The noise is more likely coming from the pulley going bad.
