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.
A 50/50 mixture of water and the proper coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should. 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.
IC ION:
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture.
With plain water or the wrong mixture,
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 mixture of clean water and the
proper coolant.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered
by your
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater
core and other parts.
If you have to add coolant more than four times a year,
lave
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.

Wrning 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.
A CAUTION:
d 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.
I NOTICE:
Your radiator cap is a 15 psi (105 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.
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, a General Motors@
thermostat is recommended.

How To Check Power Steering Fluid
You can check your fluid without taking the cap off. Just
look at the reservoir.
When the engine compartment is hot, the level
should be between the
HOT marks.
When the engine compartment is cool, the level
should be between the
COLD marks.

To determine what lund of fluid to use, see
“Recommended Fluids and Lubricants” in the Index.
I NOTICE:
When adding power steering fluid or making a
complete fluid change, always use the proper
fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol on it. Add washer
fluid until the tank is full.

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t
mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean as well
as washer fluid.
Fill your washer fluid tank only
three-quarters full when it’s very cold. This
allows for expansion if freezing occurs,
which could damage the tank
if it is
completely full.
Don’t use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.

Downloaded from www.Manualslib.com manuals search engine There are only two reasons why the brake fluid level in
the reservoir 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 level 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 off’ 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.
A CAUTION:
If you have too much brake fluid, it can spill
on the engine. The fluid will burn if the engine
is hot enough. You
or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system.
When your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light” in the Index.

Downloaded from www.Manualslib.com manuals search engine What to Add
When you do need brake fluid, use only DOT-3
brake fluid
-- such as Delco Supreme 11 @
(GM Part No. 12377967). Use new brake fluid
from a sealed container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it.
This will help keep
dirt from entering the reservoir.
With the wrong kind of fluid in your brake
system, your brakes may
not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
NOTICE:
Using the wrong fluid can badly damage
brake system parts.
For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not
to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.
