Can you bypass the supercharger on a 1993 Buick Park Avenue?
Yes, on a Series One 3800 V6 use a shorter belt... AutoZone
Duralast Multi-V belt Part Number 795K6.. which is basically a 79
1/2 inch belt. I routed the belt exactly as the diagram shows, just
omitting the Supercharger. I took it to a mechanic I trust
afterward (even though he said it couldn't be done) so he could
take a look and make sure I wasn't going to blow the motor. He said
that all his references showed no danger, just that the performance
would be "a little less peppy", and since then I've driven 1,000+
miles and everything seems to be running along just fine.
Please note: there is a power steering line that the belt may
rub against so adjust by bending that metal hose very gently upward
with a crow bar until the belt is clear (maybe 1/4 inch).
On a Series Two 3800 V6 supercharged engine, the supercharger
has it's own separate accessory belt which can simply be removed
and the car will run just fine, the computer adjusts automatically
and there are no intake manifold problems.
