Supercharged 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
38010 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.

Engine Oil
CHECK OIL
LEVEL
If the CHECK OIL
LEVEL light on the
instrument panel comes
on, it means
you need to check
your engine oil level
right away.
For more information, see “Check Oil Level Light”
in
the Index. You should check your engine oil level
regularly; this is
an added reminder.
It’s a good idea
to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.

Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed
to prevent coolant loss and possible engine
damage from overheating. Be sure the arrows
on the cap line up with the overflow tube on
the radiator filler neck.
1 I --$,. .: :; ' -%.Thermostat .
Engine coolant temperature is controlled by a thermostat
in the engine coolaxit system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear
an unusual noise. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.

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. If
necessary, add only enough fluid to bring the level up
to the
mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants”
in the Index. Always use the proper fluid.
Failure to use the proper fluid can cause leaks and
dam’age hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle
in an area where the temperature
may
fall below freezing, use a fluid that has sufficient
protection
against freezing.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY Add
washer fluid until the tank
is full.
