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.

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.

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.

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.

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

your cooling system.

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.

and scalding liquids to blow out

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.

Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
There are only two reasons why the
brake fluid level in your master cylinder
might go down. The first is that the
brake fluid goes down
to an acceptable
level during normal brake lining wear.
When new linings are put
in, the fluid
goes back up. The other reason is that
fluid is leaking out
of the brake system.
If it is, you should have your brake
system fixed, since a leak means that
sooner or later your brakes won’t work
well, or won’t work at
all.
So, it isn’t a good idea to “top ofr ’
your brake fluid. Adding brake fluid
won’t correct a leak.
If you add fluid
when your linings are worn, then you’ll
have too much fluid when you get new
brake linings. You should add (or
remove) brake fluid, as necessary, only
when work is done
on the brake
hydraulic system.

Replacing Brake System Parts
The braking system on a modern vehicle
is complex. Its many parts have to be of
top quality and work well together if the
vehicle is to have really good braking.
Vehicles we design and test have
top-quality
GM brake parts in them, as
your Geo does when it is new. When
you replace parts of your braking system
- for example, when your brake linings
wear down and you have to have new
ones put in
- be sure you get new
genuine GM replacement parts. If you
don’t, your brakes may
no longer work
properly. For example, if someone puts
in brake linings that are wrong for your
vehicle, the balance between your front
and rear brakes can change,
for the
worse. The braking performance you’ve
come to expect can change in many
other ways if someone puts in the wrong
replacement brake parts.
Battery
Every new Geo has a Delco Freedom@
battery.
You never have to add water to
one of these. When it’s time for a new
battery, we recommend a Delco
Freedom@ battery. Get one that has the
catalog number shown on the original
battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle
for
25 days or more, take off the black,
negative
(-) cable from the battery.
This will help keep your battery from
running down.
