How do you replace the supercharger oil on a Buick Regal 2001 3.8 Liter engine?

There is a hex screw located on the top of the supercharger pump (that's the beltdriven device at the top left of the engine as you face the car from the front). Unscrew the hex screw and use a hand held baster to suck out the old fluid. You then need to buy two bottles of GM Supercharger fluid. Go online and search for it. Each bottle holds 4 oz. Both should empty into the pump. I think I ordered mine from a place named paceauto.com. Remember to put the hex screw back in the pump.
