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. 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 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
Buick 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.

Explanation of Scheduled Maintenance
Services
Below 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.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification” in the Index.
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 the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is equipped with grease fittings, lubricate the suspension and steering 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.
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 protection and boil
protection, corrosion inhibitor level and maintain
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.
