2010 PONTIAC G5 check engine

Notice:Using coolant other than DEX-COOL®can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL
®(silicate-free) coolant in the
vehicle.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
{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 would not get the overheat warning.
WARNING: (Continued)
WARNING: (Continued)
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.
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.
If you have to add coolant more than four times a year,
have your dealer/retailer check your cooling system.
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.
See Recommended Fluids and Lubricants on
page 7-10 for more information.

Checking Coolant
The coolant surge tank is located in the engine
compartment on the driver’s side of the vehicle. See
Engine Compartment Overview on page 6-12for more
information on location.
{WARNING:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap — even a
little — when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the COLD
FILL line.
Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixture at the coolant surge tank, but only
when the engine is cool. If the coolant surge tank is
empty, a special fill procedure is necessary. See Engine
Overheating on page 6-27 for instructions on “How to
Add Coolant to the Coolant Surge Tank.”

5. Check that the jumper cables do not have loose ormissing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative ( −) will go to a heavy,
unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative ( −)oryou
will get a short that would damage the battery
and maybe other parts too. And do not connect the
negative (−) cable to the negative ( −) terminal on
the dead battery because this can cause sparks.
6. Connect the red positive (+) cable to the positive (+) terminal location on the vehicle with the dead
battery. Use a remote positive (+) terminal if the
vehicle has one.
7. Do not let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a
remote positive (+) terminal if the vehicle has one. 8. Now connect the black negative (
−) cable to the
negative (−) terminal of the good battery. Use a
remote negative ( −) terminal if the vehicle has one.
Do not let the other end touch anything until the
next step. The other end of the negative ( −) cable
does not go to the dead battery. It goes to a
heavy, unpainted metal engine part or to a remote
negative (−) terminal on the vehicle with the
dead battery.
9. Connect the other end of the negative ( −) cable to
the negative (−) terminal location on the vehicle with
the dead battery. Your vehicle has a remote
negative (−) terminal marked GND ( −).
10. Now start the vehicle with the good battery and run the engine for a while.
11. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs
service.

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 6-62 .
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. See Engine Oil on
page 6-13. 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. See Engine Oil Life System on page 6-16 .When the Change Oil Soon message displays, certain
services, checks, and inspections are required. The
services described for Maintenance
Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be performed when:
•Maintenance Iwas 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.
Maintenance I
•Change engine oil and filter. See Engine Oil on
page 6-13. An Emission Control Service.

•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 6-18.
•Brake system inspection (or every 12 months,
whichever occurs first).

or contamination and windshield and wiper blade
cleaning, if contaminated. SeeWindshield and Wiper
Blades on page 6-98. Worn or damaged wiper blade
replacement. See Windshield Wiper Blade
Replacement on page 6-47 .
•Body hinges and latches, key lock cylinders, and
trunk lid hinges and latches lubrication. See
Recommended 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. See Checking
the Restraint Systems on page 2-71 .
•Automatic transmission fluid level check and adding
fluid, if needed. SeeAutomatic Transmission Fluid
on page 6-19.

Cleaner/Filter on page 6-18 .
•Passenger compartment air filter replacement (or
every 12 months, whichever occurs first). More
frequent replacement may be required if vehicle is
driven regularly under dusty conditions.
