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 dealer’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 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 Geo dealer’s
service department
or another qualified service center
should perform.
I “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 Geo dealer.
This part tells you the maintenance services you should
have done and when you should schedule them.
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.
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:
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 rbad surfaces within legal
driving limits.
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:

Part 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.
Proper procedures to perform these services may be
found
in a Geo service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front- Wheel-Drive
Axle
Boot and Seal Inspection
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.
Exhaust System Inspection
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.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.
