What should i do to my supercharger mantiance wise. It'* got over 100,000 miles on it, and it'* been knocking for the past 20,000 or so. Is there anything i can do to stop that. I was just waiting till it died to get a new one.
You can change the oil in your SC. There is an alan head screw on the back side of the nose cone. Make sure that it is full and clean. You can pick up the GM approved SC oil at any dealer and a few places online. It'* not to expensive.
Also, pull your belt off and see if there is any play in the pulley. You might feel a little give between the pulley and the gear assembly inside. If so you may need to replace the coupler inside. I had to do this on my '95 SSEi just a few weeks back. That may also be the cause for idle speed noise comming from the SC.
