Engine Oil Additives
Don’t add anything to your oil. Your Geo
dealer is ready to advise
if you think
something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most
trips are less than 10 miles (1 6 km).
The engine is at low speed most of the
time (as
in door-to-door delivery, or
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
The vehicle is frequently operated
If any one of these is true for your
vehicle, then you need to change your
and filter every
3,000 miles (5 000 km) or
3 months - whichever comes first.
If none of them is true, change oil and
filter every
7,500 miles (1 2 500 km) or
7.5 months - whichever comes first.
off-road.
Engine
Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big
help
if you have to park outside in very
cold weather,
0°F (-I 8°C) or colder. If
your vehicle has this option, see “Engine
Coolant Heater”
in the Index.
What to Do with Used Oil
Did you know that used engine oil
contains elements that may be unhealthy
for your skin and could even cause
cancer? Don’t let used oil stay on your
skin for very long. Clean your skin and
nails
with soap and water, or a good hand
cleaner. Wash or properly throw away
clothing or rags containing used engine
oil. (See the manufacturer’s warnings
about
the use and disposal of oil products.)
Used oil can
be a real threat to the
environment.
If you change your own oil,
be sure
to drain all free-tlowing oil from
the filter before disposal. Don’t ever
dispose of oil by putting
it in the trash,
pouring
it on the ground, into sewers, or
into streams or bodies
of water. Instead.
recycle
it by taking it to a place that
collects used
oil. If you have a problem
properly disposing.
of your used oil, ask
your dealer,
a service station or a local
recycling center for help.
Air Cleaner
Refer to the Maintenance Schedule to
detertnine when to replace the
air filter.
See “Scheduled Maintenance Services“
ir
the Index.
A CAUTION:
Operating the engine with the air
cleaner off can cause you or others to
be burned. The air cleaner not only.
cleans the air,
it stops flame if the
engine backfires.
If it isn’t there, and
the engine backfires, you could be
burned. Don’t drive with it
off, and
be careful working
on the engine
with the
air cleaner off.

Four- Wheel Drive
Most
lubricant checks in this section also
apply to four-wheel-drive vehicles.
However, they have
two additional
systems that need lubricatiog.
Transfer Case
When to Check qnd Change Lubricant
Refer to the Maintenance Schedule to
determine how often to check the
lubricant and when to change
it. See
“Scheduled Maintenance Services”
in the
Index.
How to Check Lubricant
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant. Add enough lubricant to raise
the level to the bottom of the filler plug
hole.
What to Use
Refer to the Maintenance Schedule to
determine what kind of lybricant to use.
See “Recommended Fluids and
Lubricants”
in the Index.
Front Axle
When
to Check and Change Lubricant
Refer to the Maintenance Schedule to a
determine how often to check the
lubricant and when to change it. See
“Periodic Maintenance Inspections” and
“Scheduled Maintenance Services”
in the
Index.
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
-20°F (-29”C), or -34°F (-37°C)
in
Canada and for vehicles with the cold
climate option.
Give boiling protection up to 258°F
(125°C).
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as they
should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
6038-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to
“GM Specification
6038-M”
with a complete coolant flush
. . .I70

and refill. If you use this mixture. you
don't need to add anything else.
A CAUTION:
Adding only plain water to your
cooling system can
be dangerous.
Plain water, or some other
liquid like
alcohol, can
boil before the proper
coolant mix will. Your vehicle's
cool-
ant warning system is set for the
proper coolant
mix. With plain water
or the wrong mix, your engine could
get too hot but you wouldn't get the
overheat warning. Your engine could
catch fire and you or others could be
burned. Use a 50/50 mix of clean
water and a proper antifreeze.
NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn't be covered by your war-
ranty.
Too much water in the mix can
freeze and crack the engine, radiator,
heater core and other parts. Some conditions, such
as air
trapped in
the cooling system, can af't'ect the coolant
level
in the radiator. Check the coolant
level when the engine is cold and follow
the steps under "Adding Coolant" for the
proper way
to add coolant.
If you have to add coolant Inore than four
times
a year. have your dealer check your
cooling system.
NOTICE:
If you use the proper coolant. you
don't have to add extra inhibitors
or
additives which claim to improve thc
system. These can
be harmful.
%-Valve Engine
Adding Coolant
To Check Coolant: When your engine is
cold.
the coolant level should be at
"LOW," or a little higher. When your
engine
is warm. the level should be up to
"FULL." or a little higher.

Radiator Pressure Cap
16-Valve Engine
To Add Coo1ant:If you need to add more
coolant, add the proper mix
qt the coolant
recovery tank. Add
coolant
mix at the recovery tank, but
be careful not to spill it.
NOTICE:
Your radiator cap is a 13 psi (90 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage
from over-
heating.
Be sure the amows on the
cap line up with the overflow tube
on the radiator filler neck.
When you replace
your radiator pressure
zap, an
AC@ cap is recommended.
Thermostat
Engine coolant temperature is controlled
by a thermostat in the engine coolant
system. The thermostat stops the
flow of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat,
an
Ace' thermostat is recommended.
