2009 PONTIAC G6 Engines

What Kind of Engine Oil to Use
Look for three things:
GM6094M
Use only an oil that meets GM Standard GM6094M.
SAE 5W-30
SAE 5W-30 is best for the vehicle. These numbers
on an oil container show its viscosity, or thickness.
Do not use other viscosity oils such as SAE 20W-50.
American Petroleum Institute (API) starburst symbol
Oils meeting these
requirements should have
the starburst symbol on
the container. This symbol
indicates that the oil
has been certied by the
American Petroleum
Institute (API).
Notice:Use only engine oil identied as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certied For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
the vehicle warranty.

3. Lift off the cover.
4. Inspect or replace the engine air cleaner/lter.
5. Reverse Steps 1 through 3 to reinstall the cover and
reconnect the electrical connector.
{CAUTION:
Operating the engine with the air cleaner/lter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
ames if the engine backres. If it is not there and
the engine backres, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can easily get
into the engine, which will damage it. Always have
the air cleaner/lter in place when you are driving.
Engine Air Cleaner/Filter (All Other
Engines)
SeeEngine Compartment Overview on page 5-14for
the location of the engine air cleaner/lter.

Automatic Transmission Fluid
(2.4L L4, 3.5L and 3.6L V6 Engines)
It is not necessary to check the transmission uid
level. A transmission uid leak is the only reason for
uid loss. If a leak occurs, take your vehicle to the
dealer/retailer and have it repaired as soon as possible.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6and be sure
to use the transmission uid listed inRecommended
Fluids and Lubricants on page 6-13.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission uid listed
inRecommended Fluids and Lubricants on
page 6-13.For the 3.5L and 3.6L engines, the transmission uid
will not reach the end of the dipstick unless the
transmission is at operating temperature. If you need to
check the transmission uid level, please take the
vehicle to your dealer/retailer.
Automatic Transmission Fluid
(3.9L Engine)
When to Check and Change Automatic
Transmission Fluid
A good time to check the automatic transmission uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6and be sure
to use the transmission uid listed inRecommended
Fluids and Lubricants on page 6-13.

How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission uid to use. SeeRecommended
Fluids and Lubricants on page 6-13.
If the uid level is low, add only enough of the proper
uid to bring the level into the crosshatched area on
the dipstick.
1. Remove the dipstick.
2. Using a long-neck funnel, add enough uid at the
dipstick hole to bring it to the proper level.
It does not take much uid, generally less than
a half pint (0.24 L). Do not overll.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages may
not be covered by the vehicle’s warranty. Always
use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 6-13.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid” earlier in this section.
4. When the correct uid level is obtained, reinstall
the dipstick back in all the way.
Cooling System
The cooling system allows the engine to maintain the
correct working temperature.

When to Check Power Steering Fluid
Power steering uid is used in all vehicles with
V6 engines. Vehicles with the 4-cylinder engine have
electric power steering and do not use power steering
uid.
It is not necessary to regularly check power steering
uid unless a leak is suspected in the system or
an unusual noise is heard. A uid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
To check the power steering uid:
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the uid level on
the dipstick
The uid level should be within the crosshatched area
on the dipstick.
If the uid is at or below the ADD mark on the dipstick,
add just enough uid to bring the level within the
crosshatched area.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 6-13.
Always use the proper uid. Failure to use the proper
uid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When the vehicle needs windshield washer uid, be
sure to read the manufacturer’s instructions before use.
If the vehicle will be operating in an area where the
temperature may fall below freezing, use a uid that has
sufficient protection against freezing.
