light PONTIAC GRAND AM 1998 Repair Manual

When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the
fluid level in your clutch
master cylinder reservoir
and for the proper fluid.
See “Owner Checks and
Services” and
“Recommended Fluids and
Lubricants” in the Index.
How to Check
The proper fluid should be added if the level is at or
below the
STEP mark on the reservoir cap. See the
instructions on the reservoir cap.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
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.
J
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF (1 29 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
6-25

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.

‘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

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.”

A CAUTION:
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires
of different sizes may also cause
damage to
your vehicle. Be sure to use the same
size and type tires
on all wheels.
It’s all right to drive with your compact spare,
though. It was developed for use
on your vehicle.
I
1
A CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles
of driving. A tire and/or wheel could
fail suddenly, causing
a crash. Use only radial-ply
tires
with the wheels on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance.
(This
applies only to vehicles sold in the United States.) The
grades are molded on the sidewalls
of most passenger
car tires. The Uniform
Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare
tires, tires with
nominal rim diameters
of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger cars and light
trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible links. This greatly reduces the chance
of
damage caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse.
Be sure to
replace a bad fuse
with a new one of the identical size
and rating.
If
you ever have a problem on the road and don’t have a
spare fuse,
you can “borrow” one that has the same
amperage. Just pick
a feature of your vehicle that you
can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as
soon as you can.
There
are two fuse blocks in your vehicle: the
instrument panel fuse block and the engine compartment
fuse block.
Instrument Panel Fuse Block
The main fuse panel is located on the left side of the
instrument panel.
To access the fuses, open the fuse
panel door.
