Adding Coolant
Wrning the surge
tank pressure cap when the
engine and radiator are hot
can allow steam and
scalding
liquids to blow out and burn you badly.
Never turn the surge
tank pressure cap -- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the FULL COLD mark, or a little higher.
If the light comes on, it
means you’re low on
engine coolant.
See “Low Coolant Warning Light” in the Index.
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the surge tank, but only when the
engine is cool.
A CAUTION:
L
I
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 0n.a hot engine.
When replacing the pressure cap, make sure it is tight.

Surge Tank Pressure Cap
I NOTICE:
~~
Your pressure cap is an 15 psi (105 kPa)
pressure-type cap and must be tightly installed
to
prevent coolant loss and possible engine damage
from overheating.
When you replace your surge tank pressure cap, a GM
cap is recommended.
Thermostat
Power Steering Fluid
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 ACDelco@
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.
6-29

How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then 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.
The level should be at the
C mark. If necessary, add only
enough fluid to bring the level up to the mark.
What to Use
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.
Adding Washer Fluid
?
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the
tank is full.
6-30

NOTICE:
0
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.
Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
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
6-31

Page 265 of 370

‘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.
‘ /d 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.
BRAKE
United States Canada
When your brake fluid falls to a low level, your brake
warning light will
come on. See “Brake System Warning
Light” in the Index.
6-32

Page 266 of 370

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.
I A CAUTION:
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:
0 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.

Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake
pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time your vehicle is moving (except when
you
are pushing on the brake pedal firmly).
A
a CAUTION:
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake
wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied.
This does not mean something is wrong with
your brakes.
See “CaliperKnuckle Maintenance Inspection’’
in
Section 7 of this manual under Part C “Periodic
Maintenance Inspections.”
Properly torqued wheel nuts are necessary
to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for
wear and evenly torque wheel nuts in the
proper sequence to
GM specifications.
Your rear drum brakes don’t have wear indicators, but if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected immediately.
Also, the rear
brake drums should
be removed and inspected each time
the tires are removed for rotation or changing.
When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced
as complete
axle sets.
See “Brake System Inspection” in Section 7 of this manual
under Part C “Periodic Maintenance Inspections.”

Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your disc
brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then -- very carefully -- make a
few moderate brake stops about every
1,OOO miles
(1 600 km), so your brakes will adjust properly.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
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.
Your vehicle was designed and tested with top-quality
GM brake parts. 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 approved
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 Pontiac 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 replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more, remove the black, negative (-) cable from
the battery. This will help keep your battery from
running down.
I /I CAUTION:
Also, for your audio system, see “Theft-Deterrent
Feature” in the Index.
Jump Starting
For jump starting instructions, see “Jump Starting” in
the Index.
Bulb Replacement
This section describes bulb changing procedures for
some of your interior and exterior lamps. For bulb sizes,
see “Replacement Bulbs” in the
Index. For any bulbs not
listed in
this section, contact your service department.
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt
if you
aren’t careful. See “Jump Starting” in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer
to learn how to prepare your vehicle
for longer storage periods.
Halogen Bulbs
I
I A CAUTION:
Halogen bulbs have pressurized gas inside and
can burst
if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
