What Kind of Oil to Use:
Look for three things:
SG
SG must be on the oil container,
either by itself or combined with other
quality designations, such
as SGKC,
SG/CD, SF, SG, CC, etc. These
letters show American Petroleum
Institute (API) levels
of quality.

SAE 5W-30
As shown in the viscosity chart, SAE
5W-30 is best for your vehicle.
However, you can use SAE
1OW-30
if it’s going to be 0°F (- 18°C) or
above.

not use other viscosity oils such as

Oils with these words on the container

SERVICE
Engine Oil and Filter Change* - Always use SG
Energy Conserving I1 Oils of proper viscosity. The
SG designation may be shown alone or in
combination with others, such as SG/CC, SG/CD,
or SF, SG, CC, etc. To determine the preferred
viscosity for your vehicle’s engine (e.g., SAE
5W-30 or 1OW-30) see “Engine Oil’’ in the Index.
Engine Idle Speed Check* - Check the idle speed
and adjust it to underhood label specifications.
*An Emission Control Service.
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.
ITEM
NO. SERVICE
3 Cooling System Service* - Drain, flush and refill
the system with new or approved recycled coolant
conforming to
GM Specification 4038M. 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.
To help ensure proper operation, we recommend a
pressure test of both
the cooling system and the
pressure cap.
