How to Add Coolant to the Coolant
Over¯ow Reservoir
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch ®re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
žcoolant.If you have not found a problem yet, check the coolant
level on the coolant over¯ow reservoir dipstick. If
the coolant level is not at or above the bottom arrow on
the dipstick, add a 50/50 mixture of clean, drinkable
water and DEX-COOL
žcoolant at the coolant over¯ow
reservoir. SeeEngine Coolant on page 5-23for
more information.
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.

2006 - Pontiac GTO Owner Manual

To add coolant to the over¯ow reservoir, do the
following:
1. Remove the coolant over¯ow reservoir cap when
the cooling system is no longer hot.
2. Fill the coolant over¯ow reservoir with the proper
mixture, until it reaches the bottom arrow on the
dipstick.
3. Replace the dipstick, then press down on the
coolant reservoir cap while turning it clockwise until
it stops, to lock it into position.
{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 Ð even a little Ð they can 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.
See your dealer, if necessary.

Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned
and balanced carefully at the factory to give you the
longest tire life and best overall performance.
Adjustments to wheel alignment and tire balancing will
not be necessary on a regular basis. However, if
you notice unusual tire wear or your vehicle pulling to
one side or the other, the alignment may need to
be checked. If you notice your vehicle vibrating when
driving on a smooth road, your tires and wheels
may need to be rebalanced. See your dealer for proper
diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted
or corroded. If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts
for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
See
Changing a Flat Tire on page 5-69for more
information.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, cha®ng, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect other brake parts, including calipers,
parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts or
signs of wear. Inspect power steering lines and hoses
for proper hook-up, binding, leaks, cracks, cha®ng, etc.
(c)Visually inspect hoses and have them replaced if
they are cracked, swollen, or deteriorated. Inspect
all pipes, ®ttings and clamps; replace with genuine GM
parts as needed. To help ensure proper operation, a
pressure test of the cooling system and pressure
cap and cleaning the outside of the radiator and air
conditioning condenser is recommended at least once
a year.
(d)Visually inspect wiper blades for wear or cracking.
Replace wiper blades that appear worn or damaged
or that streak or miss areas of the windshield.
(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors, and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular maintenance.
(f)Lubricate all key lock cylinders, door hinges and
latches, hood hinges and latches, and trunk lid hinges
and latches. More frequent lubrication may be required
when exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean cloth will
make them last longer, seal better, and not stick or
squeak.
6-7
2006 - Pontiac GTO Owner Manual

(g)Change automatic transmission ¯uid and ®lter if the
vehicle is mainly driven under one or more of these
conditions:
þIn heavy city traffic where the outside temperature
regularly reaches 90ÉF (32ÉC) or higher.
þIn hilly or mountainous terrain.
þWhen doing frequent trailer towing.
þUses such as found in taxi, police, or delivery
service.
þUses such as high performance operation.
(h)Drain, ¯ush, and re®ll cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-23 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap, and ®ller neck. Pressure test the
cooling system and pressure cap.
(i)A ¯uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the ¯uid level checked. Add ¯uid if needed.
(j)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
(k)Drain, ¯ush, and re®ll brake hydraulic system (or
every two years, whichever occurs ®rst). This service
can be complex; you should have your dealer perform
this service. See Brakes on page 5-35
andRecommended Fluids and Lubricants on page 6-12.
Owner Checks and Services
These owner checks and services should be performed
at the intervals speci®ed to help ensure the safety,
dependability, and emission control performance of your
vehicle. Your GM Goodwrench
ždealer can assist you
with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any ¯uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in
Recommended Fluids and Lubricants on page 6-12.
At Each Fuel Fill
It is important to perform these underhood checks at
each fuel ®ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-13for further
details.
Notice:It is important to check your oil regularly
and keep it at the proper level. Failure to keep your
engine oil at the proper level can cause damage
to your engine not covered by your warranty.
