It is not necessary to change the oil in the supercharger. The only maintenance required is to CHECK the oil level every 30.000 miles. GM says that it is normal for some of the oil to get lost during normal use by seepage therough the front seal area. It requires 5W-30 synthetic oil.
I guess if you really want to CHANGE the oil, it would require removal of the supercharger and remove the oil fill plug and turn the supercharger upside-down to make the oil drain out.
SOURCE: installing accessory belt on 94 Buick P/Ave ultra.
You must press on tensioner to make room for new belt. The tensioner then re-traps and keep belt tension when new belt in on. So in other words you have to put belt over all othe pulley leaving tensioner for last using a 3/8 ratchet with out a socket (just the square end) in the hole thats in the tensioner pushdown/up to make room for belt to slide on. If the belt seems short make sure that it is routed the correct way. Good Luck get back to me if you need more help and leave me a "rating". Thanks
SOURCE: Where is the a/c relay on my Buick Park Ave Ultra.
Hi
If your talking about the relay switch to your air conditioner. These are usually located under the hood, behind the engine and against the center rear upper firewall, in the fuse center. You have to remove the large black plastic insulator (that spans the length of the firewall), that covers the windshield wiper motor and other components, to expose the fuse center.
Pop the fuse center cover off and read the diagram inside, so you know which relay switch goes to the A/C unit.
Should you not find the relay in the engine compartment I recommend the following.
I own a 91 Park Avenue (same body style) and on many of these modules, there are additional relays behind the glove box. This is bit tricky to get to though. Because you need a Torq/star screw driver, and you will need to remove the glove comparment to get at them.
As always be sure you disconnect the negative cable from the battery before pulling any relays, to avoid shorting out your electrical system.
Good Luck.
