Fiberglass Springs Chemical Paint Spotting
Some weather
and atmospheric
conditions can create a chemical fallout.
Airborne pollutants can fall upon and
attack painted surfaces on your vehicle.
This damage can take two forms:
blotchy, ringlet-shaped discolorations,
and small irregular dark spots etched
into the paint surface.
Although
no defect in the paint job
causes this, Oldsmobile will repair, at
no charge to the owner, the surfaces of
new vehicles damaged by this fallout
condition within 12 months or 12,000
miles
(20 000 km) of purchase,
whichever comes first.
Vehicle Identification Number
0
This is the legal identifier for your
Oldsmobile.
It appears on a plate in the
front corner of the instrument panel, on
the driver’s side. You can see it if you
look through the windshield from
outside your vehicle. The
VIN also
appears on the Vehicle Certification and
Service
Parts labels and the certificates
of title and registration.

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.
A
Performing maintenance work on a vehicle can be
dangerous. In trying to
do some jobs, you can be
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, have
a qualified technician
do the work. I
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 qual@ your vehicle for warranty repairs.

in Section E: Maintenance Record.

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 inspect 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 Ekhaust.
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. Inspect
other brake parts, including 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 whi\
ch 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 vehicle is
equipped with anti-lock brakes and the anti-lock brake system w\
arning 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 performance 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.
