Rear Axle What to Use
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level
to the bottom of the filler plug hole. Refer to the Maintenance
Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants”
in the Index.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant
is designed to remain in your
vehicle for
S years or 100,000 miles (1 66 000 km),
whichever occurs first.
The following explains your cooling system and
how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating”
in
the Index.
A SO/SO mixture of water and the proper coolant for
your Oldsmobile
will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265°F (129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

1 NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong
with
your brakes.
Your rear drum brakes don’t have wear indicators, but
if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected. Also, the rear brake drums
should be removed and inspected each time the tires are
removed for rotation or changing. When you have
the
front brakes replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or if there is
a rapid increase in pedal
travel. This could be
a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its many parts have to be of top quality and work well
together
if the vehicle is to have really good braking.
Vehicles we design and test have top-quality
GM brake
parts
in them, as your Oldsmobile does when it is new.
When you replace parts
of your braking system -- for
example, when your brake linings wear down and
you
have to have new ones put in -- be sure you get new
genuine
GM replacement parts. If you don’t, your
brakes
may no longer work properly. For example, if
someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes
can change
-- for the worse. The braking performance
you’ve come to expect can change
in many other ways
someone puts
in the wrong replacement brake parts. if

Mixing tires could cause you to lose control while
driving. If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires of different sizes may also cause
damage to your vehicle. Be sure to use the same
size and type tires on all wheels.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in
the United States.) The
grades are molded
on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters of 10 to 12 inches (25 to
30 cm),
or to some limited-production tires. While the tires available
on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from
the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction -- A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.

Vacuum and brush the area to remove any
loose dirt.
Always clean a whole trim panel or section. Mask
surrounding trim along stitch or welt lines.
Mix Multi-Purpose Powdered Cleaner following
the directions on the container label.
Use suds only and apply with a clean sponge.
Don’t saturate the material.
Don’t rub
it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.
Rinse the section with a clean, wet sponge.
Wipe
off what’s left with a slightly damp paper
towel or cloth.
Then dry it immediately with a blow dryer.
Wipe with
a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with a
clean, dull knife or scraper. Use very little cleaner, light
pressure and clean cloths (preferably cheesecloth).
Cleaning should start at the outside
of the stain,
“feathering” toward the center. Keep changing
to a clean section
of the cloth.
When you clean a stain from fabric, immediately
dry the area with
a blow dryer to help prevent a
cleaning ring.
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed
as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
3. Shoe polish, wax crayon, tar and asphalt will stain if
left
on a vehicle’s seat fabric. They should be removed
as soon as possible. Be careful, because the cleaner
will dissolve them and may cause them to spread.

1 teaspoon (5 ml) of baking soda to 1 cup (250 ml)
of lukewarm water.
4. If needed, clean lightly with solvent-type cleaner.
Combination Stains
Stains caused by candy, ice cream, mayonnaise, chili
sauce and unknown stains can be removed
as follows:
0 Carefully scrape off excess stain, then clean with
cool water and allow to dry.
0 If a stain remains, clean it with solvent-type cleaner.
Things like tar, asphalt and shoe polish will stain if
you don’t get them off quickly. Use a clean cloth and
a
GM Vinyl/Leather Cleaner or equivalent product.
Cleaning Leather

cleaners, furniture polish or
shoe polish on leather.
0 Soiled leather should be cleaned immediately. If dirt is
allowed to work into the finish,
it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections
in the windshield
and even make it difficult to see through the windshield
under certain conditions.

Headlamps
The headlamp wiring is protected by an internal circuit
breaker. An electrical overload will cause the lamps to go
on and
off, or in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and
a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until
the motor cools. If
the overload is caused by some electrical problem, be
sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load
is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by
a combination of fuses, circuit breakers,
and fusible thermal links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the band
is broken or melted, replace the fuse. Be sure you replace
a bad fuse with a new one of the identical size and rating.
lr you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
Instrument Panel Fuse Block
The fuse block is at the
driver’s end of the
instrument panel.
Remove the cover by turning
the fastener
counterclockwise. Extra fuses and the fuse extractor are
provided in the cover.
To reinstall the fuse panel cover,
push
in and turn the fastener clockwise.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly.
Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
“Automatic Transmission”
in the Index. A fluid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year

specified
in Part D.
Body Lubrication Service
Lubricate all body door hinges, the body hood, fuel door
hinges, endgate hinges, latches and locks and any
moving seat hardware. Lubricate the hood safety lever
pivot and prop rod pivot. Part
D tells you what to use.
More frequent lubrication may be required when
exposed to
a corrosive environment.
