How to Add Coolant to the Radiator
1. You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly
to
the left until it first stops. (Don't
press down while turning the
pressure cap.)
If you hear a hiss, wait for that to
stop. A hiss means there is still some
pressure
left.
2. Then keep turning the pressure cap,
but now push down as you turn
it.
Remove the pressure cap.

3. Fill the radiator with the proper mix,
up
to the base of the filler neck.

4. Then fill the coolant recovery tank to
the
FULL mark.
5. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap
off.
6. Start the engine and let it run until
you can feel the upper radiator hose
getting
hot. Watch out for the engine
fan.
By this time, the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper mix through the filler neck until the level reaches the base of the
filler neck.

gasoline, oil, coolant, brake fluid,

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
Let the warning lights work as they
-34°F (-37°C).
(125°C).
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.
ProCarManuals.com

r
Adding only plain water to
b your cooling system can be
dmgemus. Plaia water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant 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
antifreeve or approved recycled
coolant.
I
Some conditions, such as air trapped in
the cooling system, can affect 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
more than
four time
a year, have your dealer check
your cooling system.
If
you use the proper coolant, you
don’t have to add extra inhibitors
or additivies which claim to

Adding Coolant
To Check Coolant: When your engine
is cold, the coolant level should be
LOW, or a little higher. When your
engine is warm, the level should be up
to
FULL, or a little higher.
To Add Coolant: If you need more
coolant, add the proper mix
at the
coolant recovery tank.
r Turning the radiator pressure

and scalding liquids to blow out
and burn you badly. With the
coolant recovery tank, you will

Radiator Pressure Cap
IVU I IIJt
Your radiator pressure cap is a 13
- i (90 kPa) pressure-type cap and
must be tightly installed to prevent
coolant
loss and possible engine
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube on the radiato
filler neck.
I
When you replace your radiator pressure
cap, 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
AC@ thermostat is recommended.
Power Steering Fluid
How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
