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.
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 low-30), see “Engine Oil” in
the Index.
If your vehicle has an Engine Oil Life Monitor, the
monitor will show you when to change the oil. See
“Engine Oil Life Monitor”
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.

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, corrosion inhibitor level and engine
operating temperature.
