A Word About Maintenance
We at General Motors want to help you keep your vehicle in
good working condition. But we don’t know exactly how
you’ll drive
it. You may drive very short distances only a
few times a week. Or
you may drive long distances all the
time in very hot, dusty weather. You may use your vehicle in
making deliveries.
Or you may drive it to work, to do
errands or in many other ways.
Because of all the different ways people use their
GM vehicles,
maintenance needs vary. You may even need more frequent
checks and replacements than you will find in the schedules
in this part. So please read this part and note how you drive.
If you have any questions on how to keep your vehicle in
good condition, see your Oldsmobile dealer, the place many
GM owners choose to have their maintenance work done.
Your dealer can be relied upon to use proper parts and
practices.
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.

How This Part is Organized
The remainder of this part is divided into five sections:
Section
A: Scheduled Maintenance Services shows what to
have done and how often. Some of these services can be
complex,
so unless you are technically qualified and have
the necessary equipment,
you should let your dealer’s
service department or another qualified service center do
these jobs.
I
A
Performing maintenance work on a vehicle can be
dangerous. In trying to do some jobs, you can bc
seriously injured.
Do your own maintenance work
only if you have the required know-how and the proper
tools and equipment for the job. If you have any doubt,
If you are skilled enough to do some work on your vehicle,
you will probably want to get the service information GM
publishes. You will find a list
of publications and how to get
them in this manual. See the
Index under Service
Publications.
Section B: Owner Checks & Services tells you what should
be checked whenever
you stop for fuel. It also explains what
you can easily do to help keep your vehicle in good
condition.
Section C: Periodic Maintenance Inspections explains
important inspections that your Oldsmobile dealer’s service
department or another qualified service center should
perform.
Section
D: Recommended Fluids & Lubricants lists some
products GM recommends to help keep your vehicle
properly maintained. These products, or their equivalents,
should be used whether you do the work yourself or have it
done.
Section
E: Maintenance Record provides a place for you to
record the maintenance performed
on your vehicle.
Whenever any maintenance
is performed, be sure to write it
down
in this section. This will help you determine when
your next maintenance should be done. In addition, it is a
good idea to keep your maintenance receipts. They may be
needed to qualify your vehicle for warranty repairs.

WHAT SHOULD BE DONE
Inspect the front and rear suspension and steering system for damaged, loose or missing parts,
signs of wear, or lack of lubrication. Inspect the power steering lines and hoses for proper
hookup, binding, leaks, cracks, chafing, etc. Clean and then in\
spect the drive axle boot seals for
damage, tears or leakage. Replace seals if necessary.
Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken,
damaged, missing or out-of-position parts as well as open seams, holes, loose connections, or
other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes
into the vehicle. See the
Index under Engine Exhaust.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed.
Inspect the complete system. Inspect brake lines and hoses for \
proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Also
inspect drum brake linings for wear and cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc. Check parking brake adjustment.
You may need to
have your brakes inspected more often
if your driving habits or conditions result in frequent
braking.
NOTE: A low brake fluid level can indicate worn disc brake pads which may need to be
serviced. Also, if the brake system warning light stays on or comes on, something may be wrong
with the brake system.
See the Index under Brake System Warning Light. If your anti-lock brake
system warning light stays on, comes on or flashes, something may be wrong with the anti-lock
brake system. See the
Index under Anti-Lock Brake System Warning Light.

Oldsmobile regularly sends its dealers
useful service bulletins about Oldsmobile products. Oldsmobile
monitors product perfbrmance in the
field. We then prepare bulletins for
servicing our products better.
Now, you
can get these bulletins too.
Bulletins cover various subjects. Some
pertain to the proper use and care of
your vehicle. Some describe costly
repairs. Others describe inexpensive
repairs which,
if done on time with the
latest parts, may avoid future costly
repairs. Some bulletins tell
a technician
how to repair a new or unexpected
condition. Others describe a quicker
way
to fix your vehicle. They can help a
technician service your vehicle better. Most bulletins apply to conditions
affecting a small number of cars
or
trucks. Your Oldsmobile dealer or a
qualified technician may have
to
determine if a specific bulletin applies to
your vehicle.
You can subscribe to all Oldsmobile
bulletins.
This way you’ll get them as
they come out. You can wait a while and
get an index to the bulletins. You can
also get individual bulletins. However,
you’ll need the index to identify them.
