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.

premature wear, check the wheel alignment. Check
for damaged wheels also.

the system with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
