3. Check both sides of the dipstick, and read the lower
level. The fluid level must be
in the COLD area for a
cold check or
in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and Lubricants” in the Index. Add
fluid only after checking the transmission fluid
HOT. (A COLD check
is used only as a reference.) If
the fluid level is low, add only enough of the proper
fluid to bring the level up to the HOT area for a hot
check.
It doesn’t take much fluid, generally less than
one pint
(0.5 L). Don ’I ove$iZZ.
NOTICE:
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON-I11
is not covered by your new vehicle warranty.

When to Check and Change
A good time to have it checked is when the engine oil is
changed. Refer
to the Maintenance Schedule to
determine when to change your transmission fluid. See

How to Check
Because this operation can be a little difficult, you
may choose to have this done at your Geo dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
~ the fluid could come out and fall on hot engine
' parts or exhaust system parts, starting a fire. Be
~ sure to get an accurate reading if you check your
~ transmission fluid. ~
Check the fluid level only when your engine is off, the
vehicle is parked on
a level place and the transmission is
cool enough for you
to rest your fingers on the
transmission case. Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant
level is up to the bottom of
the filler plug hole.
3. If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level is low, add more
fluid
as described in the next steps.

How to Add Fluid Rear Axle
Here’s how to add fluid. Refer to the Maintenance
Schedule
to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid
to bring the fluid level up to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
When to Check and Change Lubricant
Refer to the Maintenance Schedule to 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
Clutch Adjustment
The clutch linkage in your vehicle should be checked as
recommended in your Maintenance Schedule.
To check,
push the clutch pedal down with your hand until you
feel some resistance to movement of the pedal.
If the
pedal moves freely up to
1 inch (25 mm) or so before
you feel resistance to the travel, adjustment isn’t needed.
If there
is no free travel or very little (less than 5/8 of an
inch (16 mm)), see your dealer for adjustment.
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.

Four-wheel Drive
Most lubricant checks in this section also apply to
four-wheel-drive vehicles. However, they have two additional systems that need lubrication.

Front Axle
When to Check and Change Lubricant
Refer to the Maintenance Schedule to 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 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
(I 2 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.
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant.
A 50/50 mixture of water and the proper coolant will:
0 Give freezing protection down to -33°F (-36°C).
0 Give boiling protection up to 258°F (125°C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half coolant that meets
GM
Specification 1825-M, which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. If you use this mixture, you don’t need to add
anything else.
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 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 the proper coolant.
I
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
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

Checking 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.
Adding Coolant
If you need more coolant, add the proper coolant
mixture
at the coolant recovery tank, but be careful not
to spill it.
A CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn
you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator. Never
turn the radiator pressure cap
-- even a little --
when the engine and radiator are hot.
You can be burned
if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.

Radiator Pressure Cap Power Steering Fluid
I 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 overheating. Be sure the arrows on the cap
line up with the overflow tube
on the radiator
filler neck.
When you replace your radiator pressure cap, an AC@
cap is recommended. 'I
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.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid
unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.
