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
p .w ii
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.
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.

What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part No.
1052535). Use new brake fluid from a sealed container
only, and always clean the brake fluid reservoir cap
before removing it.
Brake Wear
Your Oldsmobile has front disc brakes and rear drum
brakes.
Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads
are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal
firmly). NOTICE:
0 Don’t let someone put in the wrong kind of
fluid. For example, just a few drops of
mineral-based oil, such as engine oil, in
your brake system can damage brake
system parts
so badly that they’ll have to be
replaced.
Brake fluid can damage paint, so be careful
not to spill brake fluid on your vehicle.
If
you do, wash it off immediately. See
“Appearance Care” in the Index.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Service Parts labels and the certificates of title and
registration.
Engine Identification
The eighth character in your VIN is the engine code.
This code will help you identify your engine,
specifications, and replacement parts.
Service Parts Identification Label
You’ll find this label on the bottom of your spare tire
cover. It’s very helpful if you ever need to order parts.
On this label is:
your VIN,
0 the model designation,
paint information, and
0 a list of all production options and special equipment.
Be sure that this label is not removed from the vehicle.
Add-on Electrical Equipment
1 NOTICE:
Don’t add anything electrical to your Oldsmobile
unless you check with your retailer
fmt. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working
as they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical
to your Oldsmobile, see “Servicing
Your Air Bag-Equipped Oldsmobile” in the Index.

1 Section 7 Maintenance Schedule
I
IMPORTANT:
KEEP ENGINE OIL
AT THE PROPER
LEVEL AND CHANGE AS
RECOMMENDED
I
This section covers the maintenance required for your
Oldsmobile. Your vehicle needs these services to retain
its
safety, dependability and emission control performance.
I Plan I
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal
of important components can significantly
affect
the quality of the air we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level of emissions from your vehicle.
To help protect our
environment, and
to help keep your vehicle in good
condition, please maintain your vehicle properly.
