recycled coolant conforming to
GM
Specification 1825-M with a complete
coolant flush and refill. 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
a Droner 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
warranty. 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, the coolant
level should be at
COLD or a little
higher. When your engine is warm, the
level should be up to
HOT or a little
higher.
If this light comes on, it means you’re
low on engine coolant.

Your radiator cap is a 15 psi

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
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.
When the engine compartment is hot,
the level should be at the
H mark.
When the engine compartment is
cool, the level should be at the
C
mark.
What to Add:
Refer to the Maintenance Schedule to
determine what kind of fluid to use. See
the
Index under Fluids G Lubricants.
When adding power steering fluid
or making a complete fluid change,
always use the proper fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.
Windshield Washer Fluid
To Add:
Open the cap labeled WASHER
FLUID ONLY. Add washer fluid until
the bottle is full.

NOTICE
When using concentrated washer
fluid, follow the manufacturer’s
instructions for adding water.
Don’t mix water with ready-to-

of the washer
system. Also, water doesn’t clean

Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
Your vehicle is equipped with either
Standard Power Brakes or the Anti-
Lock Brake System.
There 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 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” 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 bralce
linings. You should add (or remove)
brake fluid, as necessary, only when
work is done on the brake hydraulic
system.
ProCarManuals.com

LUU I lUlV
If you have too much bfake
L 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 the
Index under Brake
System Warning Light.
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.

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. Vehicles
we design and
test have top-quality
GM brake parts in
them, as your Pontiac does when it is
new. 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 genuine
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

Checking Aim of the Headlights
@-DOOR MODELS)
Your vehicle has the 55 x 135 mini-
quad headlight system. These
headlights have horizontal and vertical
aim indicators. The aim has been preset
at the factory and should need no
further adjustment.
To check the aim, the vehicle should be
properly prepared as follows:
The vehicle must have all four tires on
a perfectly level surface.
The vehicle should not have any
snow, ice or mud attached to it.
There should not be any cargo or
loading of vehicle, except it should
have a full tank of gas and one person
or
160 pounds (75 kg) on the driver’s
seat.
Tires should be properly inflated.
The horizontal indicator (A) should
read
0 (zero).

Checking Aim of the Headlights
(CONT.)
To make sure your headlights are
aimed properly, read all the
instructions before beginning.
Failure to follow these instructlons
could cause damage to headlight
parts.
State inspection stations will allow a
vertical reading of up plus .76 degrees
or down minus
.76 degrees €or the
center of the bubble.
It is recommended that the upper limit
not exceed up plus
.4 degrees for the
center of the bubble. There may be
an
increased chance of being flashed if
adjustment is much above
up plus
.4 degrees.

1. Start with the horizontal (left and
right) headlight aim. Don’t try
to
adjust the vertical (up and down) aim
first.
2. Check the horizontal aim for each
headlight and adjust it as necessary.
3. Turn the horizontal aiming screw (A)
until the pointer is lined up with the
0 (zero).
4. Now adjust the vertical aim. Check
the vertical
aim for each headlight
and adjust it as necessary.
5. Turn the Vertical aiming screw until
the bubble in the level is centered at
0 (zero).
To Replace a Headlight
(2-DOOR MODELS)
Before replacing a headlight that does
not light, check to make sure that the
wiring connector is securely fastened to
it.
See the
Index under Replacement
Bulbs to check the size and type of
headlight you need to use before you
begin to replace the headlight. You
must replace a headlight with one that
is exactly the same.
1. Open the protective panel above the
headlights.
