Engine Accessory Belt
The 4.0L Aurora engine uses an engine accessory belt.
This diagram shows the features connected by the belt
routing. See”Maintenance Schedu1e”in the Index for
when to check the belt.

2. Power Steering Pump Pulley
3. Idler Pulley 4.
Alternator Pulley
5. Air Conditioner Compressor Pulley

Engine Oil
If the CHECK 01L LEVEL message or the oil warning
light on the instrument panel comes
on, it means you
need to check your engine oil level right away.
For more
information, see “Check Oil Level Message” or
“Oil
Warning Light” in the Index. You should check your
engine
oil level regularly; this is an added reminder.
It’s a
good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Turn off the engine and give the
oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.

Brake Wear
Your Aurora has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when
you are pushing on the brake pedal
firmly).
I 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.
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 YOLI apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts, and wheel nuts should be replaced.
If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes
be repaired). See your
Aurora retailer if any
of these conditions exist.
Your retailer will know the kind
of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
If you need
to replace any of your wheels, wheel bolts,
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, and wheel nuts for your Aurora
model.
I NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometer/odometer calibration, headlamp aim, bumper height, vehicle ground clearance,
and tire
or tire chain clearance to the body and
chassis.

Tires
To clean your tires, use a stiff brush with a tire cleaner.
When applying a tire dressing always take care
to wipe
off any overspray or splash from painted surfaces.
Petroleum-based products may damage the paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material
to the parts repaired or
replaced to restore corrosion protection.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal
will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your retailer or other service
outlets. Larger areas
of finish damage can be corrected
in your retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on the underbody. If these are not removed,
accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion
protection.
At least every spring,
flush these materials from the
underbody
with plain water. Clean any areas where mud
and other debris can collect. Dirt packed
in closed areas
of the frame should be loosened before being flushed.
Your retailer or an underbody vehicle washing system
can do this for you.
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.

@ Section 7 Maintenance Schedule
IMPORTANT:
KEEP ENGINE OIL
AT THE PROPER
.EVEL AND CHANGE AS
RECOMMENDED
Introduction
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
relnoval 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 lnaintain your vehicle properly.

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.
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 Publications”
in the Index.
“Part 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.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Aurora 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 Aurora 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
0
0
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle”
in the Index.
are driven
on reasonable road surfaces within legal
driving limits.
use the recommended unleaded fuel. See “Fuel” in
the Index.

right for your vehicle. Here’s how to decide which
