Service and Appearanc’e Care
The proper coolant for your Pontiac will:
0
Give freezing protection down to
-34°F (-37°C).
Give boiling protection up to 262°F
(128°C)
.
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as
they
should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant
conforming to GM Specification 1825M
with a complete coolant flush and refill. If
you use this mixture, you don’t need to
add anything else.
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.
Adding Coolant
To Check Coolant: When your engine is
cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level should be “COLD,” or a little higher.
When your engine is warm, the level on
the dipstick should be up to
“HOT,” or a
little higher.

LOW
COOLANT
f you have the 5.7L LTl (Code P) engine
nd this light comes
on, it means you’re
3w on engine coolant.
ro Add Coolant to the Recovery Tank:
f you need more coolant, add the proper
nix at the coolant recovery tank, but only
vhen your engine is cool. If the tank
is
‘ery low or empty, also add coolant to the
adiator, see “Engine Overheating” in the
ndex for information. Add
coolant mix at
the recovery tank, but
be careful not to spill it.

Service and Appearance Care
Radiator Pressure Cap (All Engines)
NOTICE:
Your radiator cap is a 18 psi (124 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage from over-
heating. 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.
3.4L L32 (Code S)
Power Sfeering Fiuid
How to Check Power Steering Fluid:
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.

0
5.7L LT1 (Code P)
When the engine compartment is hot,
the level should be at the
“H” or
“HOT” mark.
When the engine compartment is
cool, the level should be at the
“C”
or “FULL COLD” mark.

What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid - such as Delco-
Supreme ll@
(GM Part No. 1052535).
Use new brake fluid from a sealed
container only, and always clean the
brake fluid reservoir cap before
removing it.
NOTICE:
Don’t let someone put in the
wrong kind of fluid. 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.
Brake fluid can damage paint,
so
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
Unless you have the four-wheel disc
brake option, your Pontiac 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).
I NOTICE:
I
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.
If you have rear drum brakes, they don’t
have wear indicators, but if you ever hear
a rear brake rubbing noise, have the rear
brake linings inspected. 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 brakes replaced, have
the rear
brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
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.

Vehicle Identification
Number
(VIN)
rhis is the' legal identifier for your
'ontiac. It appears on a plate in the front
:orner of the instrument panel, on the
lriver's side. You can see it if you look
hrough the windshield from outside your
rehicle. The
VIN also appears on the
Jehicle Certification and Service Parts
abels and the certificates of title and
egistration.
hgine Identification
?he eighth character in your VIN is the
:ngine code. This code will help you
.dentify your engine, specifications, and
*eplacement parts.

Service Parts
Identification Label
You'll find this label inside your console
storage compartment. It's very helpful if
you ever need to order parts.
On this
label is:
D your VIN,
the model designation,
paint information, and
a list of all production options and
special equipment.
Be sure that this label is not removed
From the vehcle.
Add-on Electrical
Equipment
NOTICE:
Don't add anything electrical to your
Pontiac unless you check with your
dealer first. Some electrical equip-
ment can damage your vehicle and
the damage wouldn't be covered
by your warranty. Some add-on
electrical equipment can keep other
components from working as they
should.
Your vehicle has an air bag system.
Before attempting to add anything
zlectrical to your Pontiac, see "Servicing
Your Air Bag-Equipped Pontiac" in the
Index.

I Fuses and Circuit
Breakers
'he wiring circuits in your vehicle are
rotected from short circuits by
a
ombination of fuses, circuit breakers,
nd fusible thermal links in the wiring
self. This greatly reduces the chance of
ires caused by electrical problems.
'here are two fuse centers on your ehicle. One is in the left side of your
lstrument panel.
The other is in the engine compartment.
3pen the cover on either of the boxes to
:xpose the fuses.
>oak at the silver-colored band inside the
'use. If the band is broken or melted,
.eplace the fuse. Be sure you replace a
)ad fuse with a new
one of the correct
rize.
f you ever have a problem on the road
md don't have a spare fuse, you can
)orrow one. Just pick some feature
of
Jour vehicle that you can get along
without
- like the radio or cigarette
ighter
- and use its fuse, if it is the size
IOU need. Replace it as soon as you can.
Headlights
The headlight wiring is protected by a
circuit breaker. An electrical overload
will cause the lights to go
on and off, or in
some cases to remain
off. If this happens,
have your headlight wiring checked right
away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse. If
the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor
cools. If the overload is caused by some
electrical problem and not snow, etc.,
be sure to get it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power
windows and other power accessories.
When the current load is too heavy,
the circuit breaker opens and closes,
protecting the circuit until the problem
is fixed or goes away.
