Engine Accessory Belt
The 3800 (L27) 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.

C. Coolant Pump
D. Air Conditioning
E. Alternator

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 the3800
V6 Supercharged engine.
The power steering pump uses a Remote
reservoir mounted on the throttle wd
cruise control cable bracket. See
“Maintenance Schedule”
in the Index for
when you should check the fluid:

‘he second belt drives the supercharger,
oolant pump and air conditioning
ompressor. Each belt has its own
msioner and idler pulley.

See “Maintenance Schedule” in the Index
for when to check the accessory drive
belts and Supercharger oil level. Have
your dealer check the oil level in the
Supercharger.
Supercharger Oil
Unless you are technically qualified and
have the proper tools, you should let your
dealer or a qualified service center
perform this maintenance.
When to Check
Check oil level every 30,000 miles
(50 000 km) or every 36 months.
What Kind of Oil to Use
See “Recommended Fluids and
Lubricants” in the Index and use only the
recommended oil.
How to Check and Add Oil
Check oil only when the engine is cold.
Allow the engine to cool
2 to 3 hours after
running.

Service & Appearance Care
Thermostat
Engine coolant temperature is controlled
by a thermostat
in the engine coolant
system. The thermostat stops the flow
of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
Power Steering Fluid
How To Check Power
Steering
Fluid
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten
it. Then remove the
cap again and look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be at the
“H” mark.
When the engine compartment is cool,
the level should be at the “C” mark.
What to Add
Refer to the Maintenance Schedule to
determine what kind
of fluid to use. See
“Recommended Fluids and Lubricants”
in
the Index.
NOTICE:
When adding power steering fluid
or making a complete fluid change,
always
use the proper fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.
