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.

Windshield Washer Fluid
To Add:
Open the cap with the washer symbol on
it. Add washer fluid until the bottle is full.
NOTICE:
When using concentrated washer
tluid, follow the manuficturer’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 tluid.
Fill your washer tluid tank only
3/4 full when it’s very cold. This
allows for expansion, which could
damage the
tank if it is completely
full.
Don’t use radiator antifreeze in
your windshield washer. It can
damage your washer system and
paint.
Brake Master Cylinder
Your brake master cylinder is here. It is
‘illed with
DOT-3 brake fluid.
I‘here 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
lormal brake lining wear. When new
iinings are put
in, the fluid level goes
mck
up. The other reason is that tluid is
leaking out of the brake system.
If it is,
you should have your brake system fixed,
;ince 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 tluid won’t

Drain, flush and refill the system
with new or approved recycled
coolant conforming to
GM
Specification 182SM. Keep
coolant at the proper mixture
as
specified. See “Coolant” in the
Index. This provides proper
freeze and boil protection,
corrosion inhibitor level and
maintains proper engine
operating temperature.
Inspect hoses and replace
if
they are cracked, swollen or
deteriorated. Tighten screw-type
hose clamps. Clean the outside
of the radiator and air
conditioning condenser. Wash
the pressure cap and neck.
To help ensure proper operation,
we recommend a pressure test
of
both the cooling system and the
nressure cap.
