2010 PONTIAC G6 engine oil

What to Use
{WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch fire and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing
else needs to be added. This mixture:
•Gives freezing protection down to−37°C (−34°F),
outside temperature.
•Gives boiling protection up to 129°C (265°F),
engine temperature.
•Protects against rust and corrosion.
•Will not damage aluminum parts.
•Helps keep the proper engine temperature.Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 7-10for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
Check to see if coolant is visible in the coolant recovery
tank. If the coolant inside the coolant recovery tank
is boiling, do not do anything else until it cools down.
If coolant is visible but the coolant level is not at or above
the FULL COLD mark, add a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant at the coolant
recovery tank, but be sure the cooling system is cool
before this is done. See Engine Coolant for more
information.
The coolant level should be at or above the FULL COLD
mark on the coolant surge tank. If it is not, you may have
a leak in the cooling system.

Overheated Engine Protection
Operating Mode
This emergency operating mode lets the vehicle
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates firing groups of
cylinders helps prevent engine damage. In this mode,
there is a significant loss in power and engine
performance. The temperature gage indicates an
overheat condition exists. Driving extended distances
and/or towing a trailer in the overheat protection mode
should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. SeeEngine Oil
on page 6-21.
Power Steering Fluid
SeeEngine Compartment
Overview on page 6-16for
reservoir location.
When to Check Power Steering Fluid
Power steering fluid is used in all vehicles with
V6 engines. Vehicles with the 4-cylinder engine
have electric power steering and do not use power
steering fluid.
It is not necessary to regularly check power steering
fluid unless a leak is suspected in the system or
an unusual noise is heard. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
6-37

Do not top off the brake fluid. Adding fluid does not
correct a leak. If fluid is added when the linings are worn,
there will be too much fluid when new brake linings are
installed. Add or remove brake fluid, as necessary, only
when work is done on the brake hydraulic system.
{WARNING:
If too much brake fluid is added, it can spill on
the engine and burn, if the engine is hot enough.
You or others could be burned, and the vehicle
could be damaged. Add brake fluid only when
work is done on the brake hydraulic system.
When the brake fluid falls to a low level, the BRAKE
FLUID message in the Driver Information Center (DIC)
displays. SeeDIC Warnings and Messages on
page 4-42.
What to Add
Use only new DOT 3 brake fluid from a sealed container.
SeeRecommended Fluids and Lubricants on page 7-10.
Always clean the brake fluid reservoir cap and the
area around the cap before removing it. This helps keep
dirt from entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake fluid.
Notice:
Using the wrong uid can badly damage brake
hydraulic system parts. For example, just a few
drops of mineral-based oil, such as engine oil, in
the brake hydraulic system can damage brake
hydraulic system parts so badly that they will
have to be replaced. Do not let someone put in
the wrong kind of uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on the vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 6-110.

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service
for new tires be performed when they have
8 000 to 13 000 km (5,000 to 8,000 miles).
SeeTire Inspection and Rotation on page 6-73.
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. SeeEngine Oil on
page 6-21.An Emission Control Service.
When the Change Oil Soon message displays, service
is required for the vehicle as soon as possible, within
the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at
least once a year and the oil life system must be reset.
Your dealer/retailer has trained service technicians
who will perform this work and reset the system. If the
engine oil life system is reset accidentally, service
the vehicle within 5 000 km/3,000 miles since the last
service. Reset the oil life system whenever the oil
is changed. SeeEngine Oil Life System on page 6-24.When the Change Oil Soon message displays, certain
services, checks, and inspections are required. The
services described for MaintenanceIshould be
performed at every engine oil change. The services
described for MaintenanceIIshould be performed when:
•MaintenanceIwas performed the last time the
engine oil was changed.
•It has been 10 months or more since the Change
Oil Soon message has displayed or since the last
service.
MaintenanceI
•Change engine oil and filter. SeeEngine Oil on
page 6-21.An Emission Control Service.
•Engine coolant level check. SeeEngine Coolant on
page 6-31.
•Windshield washer fluid level check. SeeWindshield
Washer Fluid on page 6-38.
•Tire inflation check. SeeInation - Tire Pressure on
page 6-64.
•Tire wear inspection. SeeTire Inspection and
Rotation on page 6-73.
•Rotate tires. SeeTire Inspection and Rotation on

•Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system must
be repaired and the fluid level checked.
•Engine air cleaner filter inspection (vehicles driven
in dusty conditions only). SeeEngine Air Cleaner/
Filter on page 6-26.
•Brake system inspection (or every 12 months,
whichever occurs first).
MaintenanceII
•Perform all services described in MaintenanceI.

inspection for damaged, loose, or missing parts or
signs of wear.
•Engine cooling system inspection. Visual inspection
of hoses, pipes, fittings, and clamps and
replacement, if needed.

or contamination and windshield and wiper blade
cleaning, if contaminated. SeeWindshield and Wiper
Blades on page 6-112. Worn or damaged wiper
blade replacement. SeeWindshield Wiper Blade
Replacement on page 6-55.
•Body hinges and latches, key lock cylinders, folding
seat hardware, and rear compartment hinges
lubrication. SeeRecommended Fluids and
Lubricants on page 7-10. More frequent lubrication
may be required when vehicle is exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth makes them last
longer, seal better, and not stick or squeak.
•Restraint system component check. SeeChecking
the Restraint Systems on page 2-74.
•Engine air cleaner filter inspection. SeeEngine Air
Cleaner/Filter on page 6-26.
