5.7L Engine
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services”
in the Index. Operating the engine with the
air cleaner
off can
cause you or others to be burned. The
air cleaner
not only cleans the
air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires,
you could be burned. Don’t drive with
it off, and be careful working on the engine with
the
air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which
will damage it. Always
have the
air cleaner in place when you’re driving.

If you have the 5.7L LT1 engine (with the WS6 option),
your air cleaner will be located over the radiator near the
front
of the engine.
To remove the filter, remove the screws (located on the
rear edge of the air cleaner), lift the air cleaner and
remove
the filter.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every 15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more of these conditions:
In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90” F (32” C) or higher.
0 Uses such as high
performance operation.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do
not use your vehicle under any of these
conditions, change the fluid and filter every
100,000 miles ( 166 000 km),
See “Scheduled Maintenance Services” in the Index.

HQW to Check
Because this operation can be a little difficult, you may
choose to have this done at your Pontiac dealership
Service Department.
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
transmission.
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
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
When outside temperatures are above 90 OF (32 O C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at
normal operating temperature, which
is 180°F to
200°F (82OC to 93°C).
Checking Transmission Fluid Hot
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 (lO"C), drive the
vehicle in DRIVE (D) until the engine temperature gage
moves and then remains steady for
10 minutes. Then
follow the hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine off and is d
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are
50°F (10OC) or
more. If it's colder than
50°F (lO"C), you may have to
idle the engine longer. Should the fluid level be low
during a cold check,
you must perform a hot check
before adding fluid. This will give you a more accurate
reading
of the fluid level.

Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual
transmission doesn’t require changing.
How to Check
Because this operation can be difficult, you may
choose to have this done at your Pontiac dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or
you could get a false reading.
NOTICE:
Too much or too little fluid can damage your
transmission.
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
I transmission fluid.
Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the transmission is
cool
enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom
of the filler plug hole.
3. If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level
is low, add more
fluid as described in the next steps.
How to Add Fluid
Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level up to the bottom of
the filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir
is
filled with hydraulic clutch fluid.
It isn’t
a good idea to “top off” your clutch fluid. Adding
fluid won’t correct
a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
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 cylin’der reservoir and
for the proper fluid, See
“Owner Checks
and Services” and “Recommended
Fluids and Lubricants” in
the Index.
The proper fluid should
be added if the level is below
the
STEP mark on the reservoir, See the instructions on
the reservoir
cap.

Rear Axle
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole,
What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 12345977) or SAE
80W-90 GL-5 gear lubricant.
Limited-Slip Differential
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977). To completely refill
after draining, add 4 ounces
(1 18 ml) of Limited-Slip
Differential Lubricant Additive (GM Part
No. 1052358).
Then fill to the bottom of the filler plug hole with Axle
Lubricant
(GM Part No. 12345977).
Engine Coolant
The cooling s stem in your vehicle is filled with new
DEX-COOL 8 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 or if you need to add coolant
to your radiator, see “Engine Overheating” in the Index.
A
50150 mixture’ of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
e Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

NOTICE:
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.
0 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
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
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.
