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,” “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.

5.
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.
Engine Accessory Drive Belt(s) Inspection -- Inspect
the belt(s) for cracks, fraying, wear and proper tension.
Replace as needed. (Belts can have small cracks
in
individual ribs without affecting performance).
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, corrosion inhibitor level and 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.
