depends on the year. but for a series 1 motor its all one piece. no need to drain the supercharger cuz it all comes out with the sythentic oil. i would upgrade the oil pump to a high volume one.
for 1995 to 1999 models:
If the reservoir is low, top it off with GM Supercharger oil P/N 12345982 (a special 5W-30 synthetic oil).
Do not open the drain plug when the engine is hot. Let it cool at least two hours so hot oil does not spray out of the reservoir. The oil level should be at the bottom of the inspection threads in the drain plug hole.
Supercharger oil can be purchased an any GM dealer or online at gmpartsdirect.com
There is a noise on the top of my 96 S/C buick riviera engine (in the supercharger housing) Sounds to me like bearings? How do Ilubricate S/C? And when do I Change this lubricant?
Neglect to replace the supercharger oil.
The Buick Riviera with supercharger should put out 240hp
To check the supercharger oil on a 1998 Buick Riviera, locate the supercharger oil reservoir, which is typically found on the supercharger itself. Remove the fill cap and visually inspect the oil level; it should be within the designated marks on the dipstick or fill neck. If the oil level is low, use a suitable supercharger oil, which is generally a synthetic oil specifically designed for superchargers, often with a viscosity of 5W-30 or similar. Always refer to the owner's manual for specific oil recommendations and capacities.
It takes 2 bottles of the GM supercharger oil (or Ford supercharger oil, they are the same product). Do not try to substitute anything else for it either. It is a specialized oil built for the iron bearings that are used in these superchargers.
A variety of options exist. See the Reatta forum http://www.reatta.net/. What is a riviera witch?
96 doesnt have the supercharger so yes What made you think it is a 1996? It's pretty tough to mis-identify a SuperCharger?
from underneath the car you can get right to them
The 1995 Buick Riviera with a supercharger typically requires about 2.5 to 3.0 pounds of R-134a refrigerant for the air conditioning system. Additionally, it generally needs around 6 to 8 ounces of PAG oil, depending on the specific components and any previous service history. Always refer to the vehicle's service manual for the most accurate specifications and recommendations.
RIGHT SIDE OF ENGINE NEAR CRANK PULLY
Next to the pulley that is on the supercharger is a little hex nut. Take this hex nut off and drain the oil by using something to suck it out. Once all of the oil is sucked out, use "GM Supercharger Oil" which is a special blend oil and fill it back up. Make sure you fill it up to about 1/4 inch below this hex nut.
There is no button for the supercharger. The supercharger is always on because it is being driven by the belts of the engine. When you step on the gas, there is a vacuum line that is hooked up to the supercharger in which will close a little valve causing the boost to be diverted into the engine.
