How to Check (cow.)
If you do it yourself, be sure to follow all
the instructions here, or
you could get a
false reading on the dipstick.
NOTICE:
Too much or too little fluid can
damage your transaxle. Too much
can mean that some of
the fluid
could come out and fall on hot
engine parts or exhaust system
parts, starting a fire. Be sure to get
an accurate reading
if you check
your transaxle
fluid.
Wait at least 30 minutes before checking
the transaxle fluid
level if you have been
driving:
0 When outside temperatures are above
90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot
weather.
I
To get the right reading, the fluid should
be at normal operating temperature,
which is 180°F to 200°F (82°C to 93°C).
Get the vehicle warmed up by driving
about 15 miles (24 km) when outside
temperatures are above 50°F (10°C). If
it's colder than 50°F ( 10°C), you may
have
to drive longer.
To Check the Fluid Level
Park your vehicle on a level place.
Keep the engine running.
With the parking brake applied, place
the shift lever
in "P" (Park).
With your
foot on the brake pedal,
move the shift lever through each gear
range, pausing for about three seconds
in each range. Then, position the shift
lever
in "P" (Park).
Let the engine run at idle for three
to
five minutes. Then. Without Shutting
Off the Engine,
Follow These Steps:
1. Pull out the dipstick and wipe it with a
clean rag or paper towel.
2. Push it back in all the way, wait three
seconds and then pull it back
out
again.
ProCarManuals.com

3. Check both sides of the dipstick, and
read the lower level. The fluid level must be in the cross-hatched area.
4. If the fluid level is in the acceptable
range, push the dipstick back in all the
way.
How to Add Fluid
Refer to the Maintenance Schedule to
determine what kind of transaxle fluid to
use. See “Recommended Fluids and
Lubricants’’
in the Index. If
the fluid level is low, add only enough
of the proper fluid to bring the level into
the cross-hatched area on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough
fluid at the dipstick hole to bring
it to
the proper level.
It doesn’t take much fluid, generally
less than a pint
(OSL). Don’t overfill.
We recommend you use only fluid
labeled DEXR0N’-I11
or
DEXRON@-IIE, because fluids with
that label are made especially for your
automatic transaxle. Damage caused
by fluid other than DEXRON@-I11 or
DEXR0N’-IIE is not covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid
level as described under “How to
Check.”
0 When the correct fluid level is
obtained, push the dipstick back in all
the way. ..

Engine Coolant (CONT.)
What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a 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.
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
“FULL COLD” or a
little higher. When your engine is warm,
‘.he level should be up to “FULL HOT” or
1 little higher.

mix at the recovery tank, but
be careful not to spill
it.
Radiator Pressure Cap
I 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.

Service & Appearance Care
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
“Recommended Fluids and Lubricants”
in
the Index.
NOTICE:
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.

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
3/4 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.

filled with DOT-3 brake fluid. It is
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

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.
When your brake fluid falls to a low level,
your brake warning light will come on. A
chime will sound
if you try to drive with
this warning light on. See “Brake System
Warning Light” in the Index.
. . .218
What to Add
When you do need brake fluid, use only
DOT-3 brake fluid
-- such as Delco
Supreme 11
@ (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:
e 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
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).
ProCarManuals.com

NOTICE:
Continuing to drive with worn-out
brake pads could result
in costly
brake repair.
r_
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.
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.
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.
Brake Adjustment
Every time you apply the brakes
moderately, with or without the vehicle
moving, your brakes adjust for wear.
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
mes 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.
