Notice:In cold weather, water
can freeze and crack the engine,
radiator, heater core and other
parts. Use the recommended
coolant and the proper coolant
mixture.
{CAUTION
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene
glycol and it will burn if the
engine parts are hot enough.
Do not spill coolant on a hot
engine.
1. Check the engine coolant
reservoir (A) level and, if
required, top with coolant. See
Engine Coolant on page 9-13.2. Locate the radiator pressure
cap (B).
{CAUTION
Steam and scalding liquids
from a hot cooling system can
blow out and burn you badly.
They are under pressure, and if
you turn the radiator pressure
cap — even a little — they can
(Continued)
CAUTION (Continued)
come out at high speed. Never
turn the cap when the cooling
system, including the radiator
pressure cap, is hot. Wait for
the cooling system and radiator
pressure cap to cool if you ever
have to turn the pressure cap.
3. Cover the cap with a thick
cloth and turn it slowly
counterclockwise and remove.
4. If there is no coolant or the level
is low, slowly ll the system
through the radiator pressure cap
opening with a 50/50 mixture
of clean, drinkable water and
a DEX-COOL
®coolant until full.
Wait 30 seconds for coolant
to settle and top off if the
level drops.
Do not spill coolant on the
accessory drive belts.
If a spill occurs, rinse the belt
with fresh water.

5. Start the engine.
6. With the engine idling, top off the
coolant through the radiator
pressure cap opening until full.
Wait 30 seconds for the
coolant to settle and top off, if
the level drops.
7. Once the system is full, put the
radiator pressure cap back on
by turning clockwise.
8. Turn off the ignition.
9. Check the coolant level in the
reservoir and ll it until the
level is at the top of the dipstick.Power Steering Fluid
Power Steering Fluid Level
Power steering uid is used in
all vehicles.
Check the level after the vehicle has
been driven for at least twenty
minutes so the uid is warm.
How to Check Power Steering
Fluid
To check the power steering uid,
do the following:
1. Turn the key off and let the
engine compartment cool down.
2. The power steering uid reservoir
is located on the driver side
toward the front of the engine
compartment. SeeEngine
Compartment Overview on
page 9-6.3. Wipe the cap and the top of the
reservoir clean.

4. Turn the cap counterclockwise
and pull it straight up.
5. When the engine is hot, the level
should be at the hot MAX level.
When the engine is cold, the
uid level should be between
MIN and MAX on the dipstick.
6. Replace the cap.
Adding Power Steering Fluid
To determine what kind of uid
to use, seeRecommended Fluids
and Lubricants on page 11-12.
Always use the proper uid. Failure
to use the proper uid can cause
leaks and damage hoses and seals.
1. Turn the ignition to LOCK/OFF.
2. Top off with power steering
uid. Do not overll the reservoir.
3. Push the cap straight down
and turn clockwise to tighten.
Windshield Washer Fluid
What to Use
When you need windshield washer
uid, be sure to read the
manufacturer’s instructions before
use. If you will be operating
your vehicle in an area where the
temperature may fall below freezing,
use a uid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer uid
until the tank is full. SeeEngine
Compartment Overview on page 9-6

4. At the wall, measure from the
ground upward (A) to the
recorded distance from Step 3
and mark it.
5. Draw or tape a horizontal line (B)
on the wall the width of the
vehicle at the height of the mark
in Step 4.
Notice:Do not cover a headlamp
to improve beam cut-off when
aiming. Covering a headlamp may
cause excessive heat build-up
which may cause damage to the
headlamp.6. Turn on the low-beam headlamps
and place a piece of cardboard
or equivalent in front of the
headlamp not being adjusted.
Do not place it directly on
the headlamp. This allows only
the beam of light from the
headlamp being adjusted to be
seen on the at surface.
7. Locate the vertical headlamp
aiming screws, which are
under the hood near each
headlamp assembly.The adjustment screw can be
turned with a 6 mm socket
wrench.
8. Turn the vertical aiming screw
clockwise or counterclockwise
until the headlamp beam is
aimed to the horizontal tape line.
9. Make sure that the light from the
headlamp is positioned at the
bottom edge of the horizontal
tape line. The lamp on the left (A)
shows the correct headlamp aim.
The lamp on the right (B) shows
the incorrect headlamp aim.
10. Repeat Steps 7 through 9 for
the opposite headlamp.

Using the Tire Sealant and
Compressor Kit to
Temporarily Seal and Inate a
Punctured Tire
Follow these directions closely for
correct sealant usage.
A. On/Off Switch
B. Air Compressor Accessory Plug
C. Air Compressor
D. Sealant Canister
E. Sealant/Air Hose
F. Air-only Hose
G. Pressure GageDo a safety check before
proceeding. SeeIf a Tire Goes Flat
on page 9-62.
Inspect the damaged tire.
The sealant cannot seal sidewall
damage, large punctures, or a
tire that has unseated from
the wheel. SeeRoadside Assistance
Program on page 12-6.
Do not remove any objects that
have penetrated the tire.
1. Place the tire sealant and
compressor kit on the ground and
unwrap the sealant/air hose (E)
from the side of the compressor.
2. Remove the air compressor
accessory plug (B) from the unit.
Do not plug the plug in yet.
3. Turn the tire valve stem cap
counterclockwise to remove.
4. Attach the sealant/air hose (E)
onto the tire valve stem. Turn
it clockwise until tight.5. Make sure the sealant and
compressor kit on/off switch (A) is
in the O (off) position.
Plug the air compressor
accessory plug (B) into an
accessory power outlet in the
vehicle. SeeAccessory Power
Outlet(s) on page 4-9for
more information.
Do not slam door or close
window on the compressor
accessory plug cord.
{CAUTION
Idling the engine in a closed-in
place or with the climate
control system off can cause
deadly carbon monoxide (CO).
SeeEngine Exhaust on
page 8-12.
6. Start the vehicle. The vehicle
must be running while using
the air compressor.
Vehicle Service and Care 9-65
2008 - Pontiac G8 Owner Manual

11. Unplug the air compressor
accessory plug (B) from the
accessory power outlet in
the vehicle.
12. Turn the sealant/air hose (E)
counterclockwise to remove.
13. Replace the tire valve
stem cap.
14. Stow the sealant/air hose (E)
and air compressor accessory
plug (B) in their original
locations.
15. If the at tire was able to be
inated to the recommended
ination pressure, remove
the maximum speed label from
the sealant canister and
place it in a highly visible
location.The maximum speed label
reminds you to drive cautiously
and not to exceed 55 mph
(90 km/h) until you have
the damaged tire inspected and
repaired.
{CAUTION
Storing the tire sealant and
compressor kit or other
equipment in the passenger
compartment of the vehicle
could cause injury. In a sudden
stop or collision, loose
equipment could strike
someone. Store the tire sealant
and compressor kit in its
original location.
16. Return the equipment to its
original storage location in
the trunk.
17. Immediately drive the vehicle
5 miles (8 km) to distribute the
sealant evenly in the tire.18. Stop at a safe location and
check the tire pressure, refer
to Steps 1 through 9 under
“Using the Tire Sealant
and Compressor Kit without
Sealant to Inate an
Underinated Tire” later in this
section.
If the tire pressure has fallen
more then 10 psi (68 kPa),
below the recommended
ination pressure, stop driving
the vehicle. The tire is too
severely damaged and the tire
sealant and compressor
cannot seal the tire. See
Roadside Assistance Program
on page 12-6if you need
assistance.
If the tire pressure has not
dropped more than 10 psi
(68 kPa) from the recommended
ination pressure, inate the tire
back up to the recommended
ination pressure.
