1996 Buick Riviera Supercharger replacement

The shop manual will help you out alot. It gives step by step instructions. Its not a very difficult job to do. I'd rate it a 4 on a scale of 1-10. 10 being very difficult. So on top of that....the only words of wisdom I can offer you is to clean everything spotless before you start. You'll be happy you did in the end. good luck. :)

I just bought the car and the supercharger has a minor 'rattle' at idle. How is this supercharger lubricated? What are the signs of it needing to be replaced? What lube does it require? Can I buy the shop manuals from Mark when he is done?

You can buy supercharger lubricant from the dealer or, according to the manual, you can use synthetic 10w30 weight oil, which is a much cheaper route. The filler is a small plug located at the bottom of the goose neck of the supercharger. You need an allen wrench to unscrew it. The oil should be up to the bottom of the threads for the screw plug.

Thanks Mark! I thought that the plug you are referring to was the fill/level check hole. Very impressed with the car overall. Had a 95 SC but had to give it away in a divorce. Finally got another one - only this one is in much better shape and very well taken care of. Let me know how your SC replacement goes!
