1994 PONTIAC BONNEVILLE Owners Manual

Maintenance Schedule
Introduction
A Word About Maintenance
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, driving
to work, running 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 will find
in the schedules in
this part. So please read this part and note how you drive. If
you have any questions on how to keep your vehicle in good
condition, see your Pontiac dealer, the place many GM owners
choose to have their maintenance work done. Your dealer can
be relied upon to use proper parts and practices.
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 removal 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 maintain your vehicle properly.

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.
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 “Service Publications’’ in the Index.
“Section
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.
“Section C: Periodic Maintenance Inspections” explains
important inspections that your Pontiac dealer’s service
department or another qualified service center should perform.
ProCarManuals.com

“Section 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.
“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.
Section A: Scheduled Maintenance
Using Your Maintenance Schedule
Services
This section tells you the maintenance services you should
have done and
when you should schedule them. Your Pontiac
dealer knows your vehicle best and wants you to be happy with
it. 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.
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 road surfaces within legal driving
limits.
use the recommended unleaded 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:
Schedule I
Is any one of these true for your vehicle?
Most trips are less than 4 miles (6 km).
Most trips are less than 10 miles (16 km) when outside
temperatures are below freezing.
The engine is at low speed most of the time (as in
door-to-door delivery, or
in stop-and-go traffic).
”.
0 You operate your vehicle in dusty areas.
You tow a trailer. (With some models, you should never
,.’
tow a trailer. See “Towing a Trailer” in the Index.)
If any one (or more) of these is true for your driving, follow
Schedule I.
Schedule 11
Follow Schedule I1 only if none of the above conditions is true.

Maintenance Schedule
Explanation of Scheduled Maintenance
Services
Following are explanations of the services listed in Schedule I
and Schedule
11.
The proper fluids and lubricants to use are listed in Section 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.
1. Engine Oil and Filter Change* -- Always use SH or SG
Energy Conserving I1 oils
of proper viscosity. The “SH” or
“SG” designation may be shown alone or in combination
with others, such as “SH/CD,” or “SH, SG, CD,” “SG/CD,”
etc. To determine the preferred viscosity for your vehicle’s
engine (e.g., SAE 5W-30 or SAE
10W-30), see “Engine
Oil”
in the Index.
2. Chassis Lubrication -- Lubricate suspension and steering
linkage. Lubricate the transaxle shift linkage, and parking
brake cable guides, underbody contact points and linkage.
3. Tire and Wheel Rotation and Inspection -- For proper
wear and maximum tire
life, rotate your tires following the
instructions in this manual. See “Tires, Inspection &
Rotation” in the Index. Check the tires for uneven wear or
damage. If
you see irregular or premature wear, check the
wheel alignment. Check for damaged wheels also.
4. Engine Accessory Drive Belt(s) Inspection* -- Inspect
the belt(s) for cracks, fraying, wear and proper tension.
Replace as needed. (Belts can have many small cracks
in
individual ribs without affecting performance.)
5. Cooling System Service* -- Drain, flush and refill the
system with new or approved recycled coolant conforming
to GM Specification 1825M. Keep coolant at the proper
mixture as specified. See “Coolant”
in the Index. This
provides proper freeze and boil protection, corrosion inhibitor level and maintains proper engine operating
temperature.
Inspect hoses and replace
if they are cracked, swollen or
deteriorated. Tighten screw-type hose clamps. Clean the
outside of the radiator and air conditioning condenser. Wash
the pressure cap and neck.
To help ensure proper operation, we recommend a pressure
test of both the cooling system and the pressure cap.
ProCarManuals.com

6. Transaxle Service -- Change both the fluid and filter every
15,000 miles (25
000 km) if the vehicle is mainly driven
under one or more of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32 “C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing. (With some
models, you shouldn’t ever tow a trailer. See “Towing a
Trailer”
in the Index.)
0 Uses such as found in taxi, police car or delivery
service.
If you do not use your vehicle under any of these
conditions, change both the fluid and filter every 100,000
miles (166
000 km).
7. Spark Plug Replacement* -- Replace spark plugs with the
proper type. See “Replacement Parts’’
in the Index.
8. Spark Plug Wire Inspection”? -- Inspect for burns,
cracks or other damage. Check the boot fit at the coils and
at the spark plugs. Replace wires as needed.
9. Supercharger Oil Check -- Check oil every 30,000 miles
(50
000 km) or 36 months. Add the proper synthetic oil.
See “Recommended Fluids and Lubricants’’ and
“Supercharger Oil”
in the Index. (Engine must be cold
before checking oil level. Oil is pressurized when hot and
will blow out of bearing case).
1 O.Air Cleaner Filter Replacement* -- Replace every
30,000 miles (50
000 km) or more often under dusty
conditions. Ask your dealer for the proper replacement
intervals for your driving conditions.
11. Fuel Tank, Cap and Lines Inspection”? -- Inspect fuel
tank, cap and lines (including fuel rails and injection
assembly) for damage or leaks. Inspect fuel cap gasket for
an even filler neck imprint
or any damage. Replace parts as
needed. Periodic replacement of the fuel filter is
not
required.
* An Emission Control Service.
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 vehicle useful life. General Motors, however, urges that all recommended maintenance services be
performed at the indicated intervals and the maintenance be recorded in “Section E: Maintenance Record”.
