Question about Buick Riviera
If memory is correct it should be driven by the serpentine belt, which runs through one of the engine mounts.
To change the belt you'll need to support the engine (by something other than the oil pan) and pull the engine mount.
== here is another opinion== First you have to remove the belt to the alternator then you can remove the belt to the supercharger. To do this you will need a 19/32" socket and breakerbar or long ratchet.
Put ratchet on belt tensioner nut and pull toward front of car then pull belt off. There is a separate tensioner for each belt.
I hope this helps and since your doing all that work might as well sevice the supercharger too which is always forgotten.
You can buy a superchaarger 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.
Good luck and hope this helps. Dubble check though, i had a long day.
