OIL
Engine Oii
If the “LOW OIL” light on the instrumenl
panel comes on, it means you need to
check your engine oil level right away.
For more information, see
“Low Oil
Light”
in the Index. You should check
your engine oil level regularly; this is an
added reminder.
3.4L L32 (Code S)
It’s a good idea to check your engine oil
every time you get fuel. In order to get an
accurate reading, the oil must be warm
and the vehicle must be on level ground.
5.7L LTl (Code P)
Turn off the engine and give the oil a few
ninutes to drain back into the oil pan. If
’ou don’t, the oil dipstick might not show
he actual level.

To Check Engine Oil
(3.4L L32 (Code S) Engine)
Pull out the dipstick and clean it with a
paper towel or cloth, then push it back
in
all the way. Remove it again, keeping the
tip lower, and check the level.
To Check Engine Oil
(5.7L LT1 (Code P) Engine)
Pull out the dipstick slightly. Pinch the
end of the dipstick tube as you remove
the dipstick to wipe the oil from it. Then
push it all the way back in. Now remove
it without pinching the tube, keeping the
tip lower.

When to Add Oil:
If the oil is at or below the “ADD’ line,
then you’ll need to add some oil. But
you must use the right kind. This section
explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications” in the Index.

NOTICE:
Don’t add too much oil. If your
engine has
so much oil that the oil
level gets above the cross-hatched
area that shows the proper operating
range, your engine could be dam-
aged.

What Kind of Oil to Use:
3eginning midyear 1993, oils of the
roper quality for your vehicle will be
dentified with this new “starburst”
‘ymbol. The “starburst” symbol indicates
hat the oil has been certified by the
imerican Petroleum Institute (API), and
s preferred for use in your gasoline
mgine.
r‘ou should
look for this on the front of
he oil container, and use only oils that
lisplay this new symbol.
You should also use
the proper viscosity
il for your vehicle, as shown in the
following chart.

Oils with these words on the
container will help you save fuel. These three things are usually
included in a doughnut shaped logo

with the doughnut shaped symbol,
containing the three things noted
above.
NOTICE:
If you use oils that do not have
either the “starburst” symbol or an
API SH or SG designation, you can
cause engine damage not covered
by your warranty.

When to Change Engine Oil:
See if any one of these is true for you:
Most trips are less than 4 miles
0 It’s below freezing outside and most
trips are less than
10 miles ( 16 km).
The engine is at low speed most of
the time (as in door-to-door delivery,
or
in stop-and-go traffic).
(6 km).
You tow a trailer often.
Most trips are through dusty places.
If any one of these is true for your
vehicle, then you need to change your
and filter every
3,000 miles (5 000 km) or
3 months - whichever comes first.
If none of them is true, change the oil
every
7,500 miles (12 500 km) or 12
months
- whichever comes first.
Change the filter at the first oil change
and at every other oil change after that.
Engine Coolant Heater (Engine Block
Heater):
An engine coolant heater can be a big
help if you have to park outside in very
cold weather,
0°F (-18°C) or colder. If
your vehicle has this option, see “Engine Coolant Heater” in the Index.
What to Do with Used Oil:
Did you know that used engine oil
:ontains elements that may be unhealthy
:or your skin and could even cause
:ancer? Don’t let used oil stay on your
;kin for very long. Clean your skin and
lails with soap and water, or a good hand
:leaner. Wash or properly throw away
:lothing or rags containing used engine
il. (See the manufacturer’s warnings
ibout the use and disposal of oil
xoducts.)
Used oil can be a real threat to the
mvironment. If you change your own oil,
)e sure to drain all free-flowing oil from
:he filter before disposal. Don’t ever
jispose of oil by putting it in the trash,
2ouring it on the ground, into sewers, or
into streams or bodies
of water. Instead,
recycle it by taking it to a place that
collects used oil. If you have a problem
properly disposing of your used oil, ask
your dealer, a service station or a local
recycling center for help.

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. Refer to the
Maintenance Schedule to determine when
to change your fluid. See “Scheduled
Maintenance Services” in the Index.
How to Check:
Because this operation can be a little
difficult, you may choose to have this
done at a 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.
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, 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
At high speed for quite a while.
In heavy traffic - especially in hot
90°F (32°C).
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 (82°C to 93°C).
To check 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
“D’ (Third Gear) until the
engine temperature gage moves and then
remains steady for
ten minutes. Then
follow the hot check procedures.
To check 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 used only as a reference.
Let the engine run at idle for five minutes
if outside temperatures are 50°F
(10°C)
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.
To check the fluid hot or cold:
0
Park your vehicle on a level place.
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
minutes or more.

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.

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.
