NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL TM (silicate-free) coolant.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL
TM coolant which
won’t damage aluminum parts. Use GM Engine Coolant
Supplement (sealer) (GM Part
No. 3634621) with any
complete coolant change.
If you use this mixture, you
don’t need to add anything else.

When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then 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 between the
ADD and FULL marks.
If necessary, add only enough fluid to bring the level up
to the proper range.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Index. Always use the proper fluid.
Failure to use the proper fluid can cause leaks and
damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY with the
washer symbol on it. Add washer fluid until the tank is
full.

So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings are worn, then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
a
-
I CAUTION:
If you have too much brake fluid, it can spill on the
engine. The fluid will burn if the engine is
hot
enough. You or others could be burned, and your
vehicle
could be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections”
in the Index.
Checking Brake Fluid
You can check the brake fluid without taking off the cap.
Just look at the windows
on the brake fluid reservoir.
The fluid levels should be above
MIN. If they aren’t,
have your brake system checked to see
if there is a leak.
After work
is done on the brake hydraulic system, make
sure
the levels are above MIN and below the top of
each window.

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
( 10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires
as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation
is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your tires, always
use the correct rotation
pattern shown here.
If your vehicle has a compact spare
tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the
Certificationmire label. Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Toraue” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you
need to, to get all the rust or dirt off. (See
“Changing a Flat Tire” in the Index.)

How This Section is Organized
The remainder of this section is divided into five parts:
“Part
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 retailer’s service department
or another
qualified service center do these jobs.
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.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications”
in the Index. “Part
B: Owner Checks and Services”
tells you what
should be checked and when. It also explains what you
can easily do to help keep your vehicle
in good condition.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Oldsmobile retailer’s
service department or another qualified service center
should perform.
“Part
D: Recommended Fluids and 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.
“Part
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 part. 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.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
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’ll find
in the schedules in this section. So please read this
section and note how
you drive. If you have any
questions
on how to keep your vehicle in good
condition, see your Oldsmobile retailer.
This part tells you the maintenance services you should
have done and
when you should schedule them. If you
go to your retailer for your service needs, you’ll know
that GM-trained and supported service people
will
perform the work using genuine GM parts. The proper fluids
and lubricants to use are listed
in
Part 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.
These schedules are
for vehicles that:
0 carry passengers and cargo within recommended
limits.
You will find these limits on your vehicle’s
Certification/Tire label. See “Loading Your Vehicle”
in the Index.
are driven on reasonable road surfaces within legal
driving limits.
0 use the recommended fuel. See “Fuel” in the Index.
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:
