On the V8 engine you’ll see this:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fans
If the coolant inside the coolant recovery
tank is boiling, don’t do anything else
until it cools down.
When it
is cool, remove the coolant
recovery tank cap and look at the dipstick.
The coolant level should be at
or above
“FULL
COLD.” If it isn’t, you may have
a leak in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system.
NOTICE:
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
If there seems to be no leak, check to see
if the electric engine fan is running. If the
engine
is overheating, the fan should be
running.
If it isn’t, your vehicle needs
service.

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.

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

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.

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.

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.
