1997 PONTIAC PONTIAC Owners Manual

What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM coolant which
won’t damage aluminum parts.
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
DEX-COOL TM coolant.
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.
~~
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 the COLD mark or a little higher. To check coolant
level, remove the cap on the coolant recovery bottle and
verify that
the coolant level is up to the COLD fill level
on the hose attached to the cap.
LOW
COOLANT
If this light comes on, it
means
you’re low on
engine coolant.
Adding Coolant
If you need more coolant, add the proper DEX-COOL”
coolant mixture at the mulant recovery tank.
If the coolant recovery tank is completely empty, add
coolant
to the radiator. (See “Engine Overheating” in
the
Index.)

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.
Add coolant mix at the recovery tank, but be careful not
to spill it.
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.
I I
Radiator Pressure Cap
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.
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
3100 Engine 3800 or 3800 Supercharged Engine
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.

How To Check Power Steering Fluid
When the engine compartment is cool, 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.
3100 Engine
When the engine
compartment
is hot, the
level should be at the
H or
HOT mark. When it’s cold,
the le.vel should be at the
C or COLD mark. If the
fluid
is at the ADD mark,
you should add fluid. 3800 or 3800 Supercharged Engine
What to Use
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index. 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.
Your vehicle may be equipped with one of
the following
windshield washer fluid reservoirs.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY. 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, 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.
Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.

There are only two reasons wny 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’ y’our 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.
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.
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.
