Changing supercharger oil

I have a 1998 buick riviera, and I want to change the supercharger oil. After taking the cover off, where is the opening located? Someone showed me how to do this about 40,000 miles ago, using a turkey baster, but I can't remember or seem to see where the opening is. I see what looks like it might be it - a small area where I'd have to use an allen wrench - Is that it?

    Yes that is the fill hole



1 Answer

It takes a 3/16 allen wrench to open the port to check and add fluid which is on the top of the charger just left of the cover. You don't need to take the cover off to access.

My belt for the supercharge broke can I still drive the car?? 1997 riviera

Yes, you can still drive the car. No real damage will occur, but performance will be poor. It's not impossible to change the belts, just time consuming with the way the belt is run around the motor mount bracket.

How frequently should i change my 1995 buick riviera supercharger oil and whats the easiest way?

This is very smelly oil so make sure to be prepared with some latex gloves.... You should change this oil ever 50 to 75 thousand miles. To do this you need to turn out the hex plug on the snout of the M90 eaton charger. Take a pump from a lotion bottle that is clean and dip the tube allll the way into the hole(reservoir). Now pump the fluid out into a plastic jar of some sort. There will be aprox. 6 ounces of fluid in the snout housing. Refill with GM supercharger oil only!!

Need to replace supercharged engine and trans. in a 96 Riviera

Faster and safer to drop the whole unit from the bottom with the cradle. Replace the supercharger snout bearing and seal before you install the replacement engine and the supercharger belt. Also replace the boost valve to your transmission just to ensure your getting the proper transmission line pressure throughout your transmission.
Thank you for using fixya and be safe

How do u change the supercharger oil?

To change the oil on the supercharger that Buick Riviera is equipped with first remove the plastic cover directly over the supercharger. Next, stand on the passenger side of the vehicle and face the engine. You will be looking at the front of the supercharger. The oil fill port is located on the front portion of the supercharger along the right hand side as viewed from your position. It is a large hex plug. This is both the drain port and fill port. There are several ways to drain the oil. My personal favorite is a piece of rubber tubing and a large syringe. I have found this to be the quickest way. Once you have drained it use a funnel small enough to fit the fill port and take your time filling it. Fill it to just below the threads at the bottom of the oil port. Be careful not to overfill it. After you have replaced the oil plug I like to disconnect the coil wire. This allows the engine to turn over but not start up. It helps to circulate the new oil through out the supercharger that were drained dry. This is not required however. It is my own personal preference. From this point it's ready to go.

Water pump

Too complicated to explain a Chiltons Manual at Auto Zone or NAPA $25...not too bad of a job but you should have a thorough knowledge of tools.
Good Luck
