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.
These numbers
on an oil container
show its viscosity, or thickness. Do
not use other viscosity oils such as
SAE
1OW-40 or SAE 2OW-50.
Energy Conserving I1
Oils with these words on the container
will help you save fuel.

Service & Appearance Care
How to Check Lubricant:
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant.
If the differential is at operating
temperature (warm), add enough
lubricant to raise the level to the bottom
of the filler plug hole.
If the differential
is cold, add enough
lubricant to raise the level to
1/2 inch
(12 mm) below the filler plug hole.
What to Use:
Refer to the Maintenance Schedule to
determine what kind of lubricant to use.
See “Recommended Fluids and
Lubricants” in the Index.
Engine Coolant
The following explains your cooling
system and how to add coolant when it
is low. If you have a problem with
engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your Geo will:
Give freezing protection down to
Give boiling protection up to 258°F
Protect against rust and corrosion.
Help keep the proper engine

temperature. should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze or approved recycled coolant
that meets “GM Specification 6038M,”
which won’t damage aluminum parts.
Also use GM Engine Coolant
Supplement (sealer) with a complete
coolant change. If you use these, you
don’t need to add anything else.

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.
