1993 PONTIAC GRAND-AM maintenance

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.
Performing maintenance work on a vehicle can be
3 dangerous. In trying to do some jobs, you can be
.-' wsly injured. Do your own maintenance work
UIUY 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.
I
If you are skilled 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 the
Index under Service
Publications.
Section B: Owner Checks & 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.
Section
C: Periodic Maintenance Inspections explains
important inspections that your Pontiac 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.

people will perform the work using genuine GM parts.
