lock PONTIAC GTO 2004 Repair Manual

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. SeeRecommended
Fluids and Lubricants on page 6-13.
Add fluid only after checking the transmission fluid while
it is hot. A cold check is used only as a reference. If
the fluid level is low, add only enough of the proper fluid
to bring the level up to the HOT area for a hot check.
The level should never read over the HOT mark, so be
careful not to add too much. It doesn’t take much
fluid, generally less than 0.6 pints (0.3 L). Don’t overfill.Notice:We recommend you use only uid labeled
DEXRON
®-III, because uid with that label is
made especially for your automatic transmission.
Damage caused by uid other than DEXRON
®-III is
not covered by your new vehicle warranty.
•After adding fluid, recheck the fluid level as
described under “How to Check.”
•When the correct fluid level is obtained, push the
dipstick back in all the way.
Remember to always replace the dipstick and lock
the handle down.
•If fluid has to be added often, there may be a
problem or leak and you should see your vehicle
dealer.

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixtureat the surge tank, but only when the
engine is cool.
{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.
When the level is correct, replace the cap and turn
clockwise until secure.
Engine Overheating
Immediate action is required if your engine overheats.
This is indicated by the coolant temperature gage
and the Engine Temp Hot message on the trip computer
display.Engine Coolant Temperature Gage on
page 3-28.
If Steam Is Coming From Your Engine

{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
®coolant.
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. Park the vehicle on a level surface.
You can remove the coolant surge tank pressure
cap when the cooling system, including the coolant
surge tank pressure cap and upper radiator
hose, is no longer hot. Turn the pressure cap slowly
counterclockwise (left) about two or two and
one-half turns. If you hear a hiss, wait for that to
stop. This will allow any pressure still left to be
vented out the discharge hose.
2. Keep turning the pressure cap slowly, and
remove it.

Power Steering Fluid
When to Check Power Steering Fluid
SeeEngine Compartment Overview on page 5-12
for reservoir location.
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
The fluid level should be checked after the vehicle has
been driven for at least 20 minutes, so that the fluid
is warm. A convenient time is when stopping for
gas. The cold level check should only be used after the
engine has not been running for at least five hours.
However, the hot level check is always recommended.
The fluid level can be viewed through the reservoir.
The level markings are next to the fluid window. When
the fluid is cold the level should be between the
COLD MIN and MAX marks; when the vehicle has been
driven for awhile and the fluid is hot the level should
be between the HOT MIN and MAX marks. If fluid must
be added, undo the cap counterclockwise to the
stop; then the cap can be lifted off. Do not overfill and
remember to replace the cap tightly. If you often need to
add fluid, you should see your dealer. Remember to
secure the cap when the level is correct and clean up
any spillage.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 6-13.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning flashers.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put an automatic transmission shift lever
in PARK (P), or shift a manual
transmission to FIRST (1) or
REVERSE (R).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
CAUTION: (Continued)
CAUTION: (Continued)
Put the wheel blocks at the front and rear of
the tire farthest away from the one being
changed. That would be the tire on the other
side, at the opposite end of the vehicle.
The following steps will tell you how to use the jack and
change a tire.

{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get
under a vehicle when it is supported only by
a jack.

positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.4. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the compact
spare tire to fit underneath the wheel well.
The jack handle must be unfolded to a right angle
before it is used.
5. Remove all of the wheel nuts.
6. Remove the flat tire.
