The 3800 (L36) engine uses an engine accessory belt.
This diagram shows the features connected by the belt
routing. See “Maintenance Schedule” in the Index for
when to check the belt.

3800 Supercharged (L67) Engine
(Option)
Your Bonneville may have a 3800 Supercharged engine.
The Supercharger is
a device which is designed to pump
more air into the engine than it would normally
use.
This air mixed with fuel, creates increased engine
power. Since the Supercharger is a pump and is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
The powertrain control module
(PCM), works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling
and light throttle cruising, the excess air that the
Supercharger is pumping is routed through a bypass.
All
of these controls, working together provide high
performance character
and fuel efficiency in the
3800 V6 Supercharged engine.
The power steering pump uses a remote reservoir
mounted on the throttle and cruise control cable bracket.
See “Maintenance Schedule”
in the Index for when you
should check the fluid.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the rear
edge
of the driver’s door shows the correct inflation
pressures for your tires, when they’re cold.
“Cold”
means your vehicle has been sitting for at least three
hours or driven no more than a mile.
NOTICE:
Don’t let anyone tell you that un’derinflation or
overinflation is all right. It’s not. If your tires
don’t
have enough air (underinflation] you can
get:
0 Too much flexing ’ i . ’:+?,,%
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
. . . .> .’“’
NOTICE: (Continued)
NOTICE: (Continued)
If’ your tires have too much air (overinflation),
you can get:
Unusual wear
Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 Pa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell you the
pressure, especially if you have radial tires
-- which
may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping
out dirt and
moisture.
