Ok, the supercharger coupler is going in my car, I also believe it is the cause for a squeeling sound everytime I step on the gas. How do I gop about changing the coupler. Can I just remove the nose drive, or do I have to remove the whole supercharger from the kintake manifold.

depends on what year your car is..

please put your year and trim level in your signature

I've never heard of a bad coupler causing a squeel.

1992 SSEi

Could a bad idler pully cause a squeel or could the coupler be causing it?

Put 92 SSEi in your signature please.

How do you know the squeal is even anything to do with the SC? Have you tried to run it for a SHORT period of time with one belt, then the other? Are your belts glazing? Do your other pulleys spin freely?

I didnt run the car with one belt. The belts arent slipping at all and the pullys all move freely. I used a stethoscope for automotive use and the the squeeling sounds like its coming from the sc.

I definitly need to change the coupler so do I need to remove the sc from the intake manifold or am I able to just remove the nose drive? thanks

on the 92 I believe you have to remove the sc to get the nose drive off

Do you plan on replacing the nosedrive bearings while you're in there? IMO it'* far more likely the bearings are making the noise than the coupler.
