service Oldsmobile Aurora 1998 s Workshop Manual

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. 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 retailer’s
service department or another qualified service
center should perform.
“Part D: Recommended Fluids and Lubricants”
lists some recommended products 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
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.
This schedule is for vehicles that:

limits. You will find these limits
on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle”
in the Index.

driving limits.
use the recommended fuel. See “Fuel” in the Index.

Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166 000 km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles (240
000 km) should be performed at
the same interval after 150,000
miles (240 000 km).
See “Owner Checks and Services’’ and “Periodic
Maintenance Inspections” following.
Footnotes
f‘ The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at
the indicated intervals and the maintenance
be recorded.
+ A good time to check your brakes is during tire
rotation.
See “Brake System Inspection” under “Periodic
Maintenance Inspections” in Part
C of this schedule.
# Lubricate the suspension and steering linkage,
transaxle shift linkage, parking brake cable guides
and underbody contact points and linkage.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- usually between 3,000 miles (5 000 km)
and 7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12 500 km) or 12 months
without an oil and filter change.
The system won’t detect dust in the oil.
So if you drive
in
a dusty area, be sure to change your oil and filter
every
3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON message appears. Remember to reset the
Oil Life Monitor when the oil has been changed. For
more information, see “Engine Oil Life Monitor” in
the Index.
