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.

Power Steering Fluid
How To Check Power Steering Fluid
When the engine compartment is cool, 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.
The level should be at the FULL
COLD mark. Add
enough fluid to bring the level up to the mark.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired. The
power steering fluid reservoir on the
L67 engine is
to the right
of the supercharger and in front of the
transaxle dipstick.
The power steering fluid reservoir on the
L36 engine is
located below the alternator and behind the accessory
drive belt.
What to Add
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index.
I
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.
