Introduction
A Word About Maintenance
We at General Motors want to help you
keep your vehicle in good working
condition. But we don’t laow 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 Environmen
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. If
you are skulled 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
Service Publications
in the Index.
“Section B: Owner Checks and
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.
ProCarManuals.com

“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.
Section A: Scheduled
Maintenance Services
Using Your Maintenance
Schedules
This section tells you the maintenance
services you should have done and
when you should schedule them. Your
Oldsmobile dealer knows your vehicle
best and wants you to be happy with it.
If you go to your dealer for your service
needs, you’ll know that GM-trained and
supported service people will perform
the work using genuine GM parts.
These schedules are for vehicles that:
carry passengers and cargo within
recommended limits.
You will find
these limits
on your vehicle’s
Certificatioflire label. See the
Index
under Loading Your Vehicle.
are driven on reasonable road
surfaces within legal driving limits.
use the recommended unleaded fuel.
See the
Index under Fuel.
Selecting the Right Schedule
First you’ll need to decide which of the
two schedules is right for your vehicle.
Here’s how to decide which schedule to
follow:
Schedule I
Is any one of these true for your
vehicle?
Most trips are less than 4 miles (6
km) .
Most trips are less than 10 miles (16
km) when outside temperatures are
below freezing.
The engine is at low speed most of the
time (as in door-to-door delivery, or
in
stop-and-go traffic).
areas or off-road frequently.
You operate your vehicle in dusty
You tow a trailer.
If any one (or more) of these is true for
your driving, follow Schedule
I.
Schedule I1
Follow Schedule I1 only if none 01 me
above conditions is true.

Explanation of Scheduled
Maintenance Services
Below are explanations of the services
listed in Schedule I and Schedule 11.
The proper fluids and lubricants to use
are listed in Section
D. Make sure
whoever services your vehicle uses
these. All parts should be replaced and
all necessary repairs done before you or
anyone else drives the vehicle.
ITEM SERVICE
NO.
1. Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be
shown alone or in combination with
others, such as “SH/CD,”
“SH, SG,
CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE 5W-30 or SAE 1OW-
30), see the Index under Engine Oil.
2. Chassis Lubrication - Lubricate the
transmission shift linkage, parking
brake cable guides, underbody contact points and linkage. Lubricate the front
suspension and steering linkage.
3. Tire and Wheel Rotation and
Inspection
- For proper wear and
maximum tire life, rotate your tires
following the instructions
in this
manual. See
Tires, Inspection G.
Rotation in the Index. Check the
tires for uneven wear or damage. If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.
Inspection - Inspect the drive belt
for cracks, fraying, wear and proper
tension. Replace as needed.
5. Cooling System Service‘: - Drain,
flush and refill the system with new
or approved recycled coolant
conforming to
GM Specification
6038-M. Keep coolant at the proper
mixture as specified. See
CooZant in
the
Index. This provides proper
freeze and boil protection, corrosion
inhibitor level and maintains proper
engine operating temperature.
Inspect hoses and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps. Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
4. Engine Accessory Drive Belt
To help ensure proper operation, we
recommend
a pressure test of both the
cooling system and the pressure cap.
6. Transmission Service - Change
both the fluid and filter every 15,000
miles
(25 000 lun) if the vehicle is
mainly driven under one or more of
these conditions:
In heavy city traffic where the
outside temperature regularly
reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police
If you do not use your vehicle under
any of these conditions, change both
the fluid and filter every

14. Differential (Axle) Service-Check
rear/front differential fluid level and
add as needed. Check constant
velocity joints and axle seals for
leaking.
Locking Rear Differential -Drain
fluid at first engine oil change and
refill. Check fluid level and add as
needed at subsequent oil changes. In
dusty areas, or trailer towing
applications, drain fluid at every
15,000 miles (25 000 ltm) and refill.
More frequent lubrication may be
required during heavy-duty or off-
road use. A fluid loss in this system
may indicate
a problem. Have it
inspected and repaired at once.
15. Brake Systems Inspection-When
the engine oil is changed, inspect
the lines and hoses for proper
hookup, binding, leaks, craclts,
chafing, etc. Check the parking
brake adjustment and the fluid level
in the master cylinder. A low brake
fluid level can indicate worn disc
brake pads which may need to be
serviced.
A fluid loss in this system may indicate a problem. See
the
Index under Brake System Warning
Light. When the wheels are
removed for rotation, inspect disc
brake pads for wear and rotors for
surface condition. Also inspect
drum brake linings for wear and
craclts. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, etc. at the
same time.
You may need to have your brakes
inspected more often
if your driving
habits or conditions result in
frequent braking.
16. Transfer Case Fluid Change -In
heavy or frequent trailer towing
applications, drain fluid and refill
every
30,000 miles (50 000 ltm).
'$ = An Emission Control Service.
f = The US. Environmental Protection Agency
or the California Air Resources Board has
determined that the failure to pelform this
maintenance item will not nullify the
emission warranty or limit recall liability
prior
to the completion of vehicle useful life.
General Motors, however, urges that
all
recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded
in "Section E:
Maintenance Record. ''

Section C: Periodic Maintenance Inspections
Listed below are inspections and services which should be performed at least twice a year (for instance, each spring and fall).
You should let your GM dealer’s service department or other qualified service center do these jobs. Make sure any necessary
repairs are completed at once.
Restraint Systems Steering, Suspension
and Rear-Wheel-
Drive Axle Boot and
Seal Inspection
Exhaust System
Inspection
WHAT SHOULD BE DONE
Now and then, make sure all your belts, buckles, latch plates, retractors, anchorages and
reminder systems are working properly. Look for any loose parts or damage. If you see anything
that might keep
a restraint system from doing its job, have it repaired.
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 hook-
up, 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
Engine Exhaust in the Index.
