tow GMC YUKON DENALI 2004 Repair Manual

What to Use
To determine what kind of ¯uid to use, seeRecommended 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 you need windshield washer ¯uid, be sure to read
the manufacturer's instructions before use. If you will
be operating your vehicle in an area where the
temperature may fall below freezing, use a ¯uid that has
sufficient protection against freezing. See
Engine
Compartment Overview on page 5-12for reservoir
location.
Adding Washer Fluid
Your vehicle has a low washer ¯uid message that
comes on when the washer ¯uid is low. The message is
displayed for 15 seconds at the start of each ignition
cycle. When the CHECK WASHER FLUID message is
displayed, you will need to add washer ¯uid to the
windshield washer ¯uid reservoir.The windshield washer
¯uid reservoir is located in
the engine compartment
toward the front of the
vehicle on the driver's side.
Open the cap with the washer symbol on it. Add washer
¯uid until the tank is full.
Notice:
·When using concentrated washer ¯uid, follow
the manufacturer's instructions for adding
water.
·Do not mix water with ready-to-use washer ¯uid.
Water can cause the solution to freeze and
damage your washer ¯uid tank and other parts
of the washer system. Also, water does not
clean as well as washer ¯uid.
·Fill your washer ¯uid tank only three-quarters
full when it is very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
·Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.

When rotating your tires, always use the correct rotation
pattern shown here.
Do not include the spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear in¯ation pressures as shown on the tire and loading
information label. See
Loading Your Vehicle on
page 4-44andIn¯ation - Tire Pressure on page 5-62,
for more information. Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº
under
Capacities and Speci®cations on page 5-112.
If your vehicle has the Tire Pressure Monitor (TPM)
system, the sensors will need to be reset after a
tire rotation is performed. See ªTPM Sensor
Identi®cation Codesº under
Tire Pressure Monitor
System on page 5-64.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. See ªChanging a Flat
Tireº in the Index.

If a Tire Goes Flat
It's unusual for a tire to ªblowoutº while you're driving,
especially if you maintain your tires properly. If air goes
out of a tire, it's much more likely to leak out slowly.
But if you should ever have a ªblowout,º here are a few
tips about what to expect and what to do:
If a front tire fails, the ¯at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel ®rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you'd use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a ¯at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a ¯at tire.
If a tire goes ¯at, the next part shows how to use your
jacking equipment to change a ¯at tire safely.

3. Insert the hoist end
(open end) (F) of the
extension through
the hole (G) in the rear
bumper.
Be sure the hoist end of the extension connects
into the hoist shaft (E). The ribbed square end
of the extension is used to lower the spare tire.
4. Turn the wheel wrench (H) counterclockwise to
lower the spare tire to the ground. Continue to
turn the wheel wrench until the spare tire can be
pulled out from under the vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire
not to lower. See ªSecondary Latch Systemº later in
this section.5. The wheel wrench has
a hook that allows you
to pull the hoist
cable towards you to
assist in reaching
the spare tire.
6. When the tire has been
lowered, tilt the
retainer (D) at the end
of the cable so it
can be pulled up
through the wheel
opening.
7. Put the spare tire near the ¯at tire.

{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to, to
get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.6. After mounting the
spare, put the wheel
nuts back on with the
rounded end of the nuts
toward the wheel.
Tighten each wheel nut
by hand. Then use the
wheel wrench to tighten
the nuts until the wheel
is held against the hub.
7. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
8. Tighten the nuts ®rmly
in a crisscross
sequence as shown by
turning the wheel
wrench clockwise.
5-83

{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque speci®cation. See ªCapacities
and Speci®cationsº in the Index for wheel nut
torque speci®cation.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque speci®cation. See ªCapacities and
Speci®cationsº in the index for the wheel nut torque
speci®cation.When you reinstall the regular wheel and tire, you must
also reinstall the center cap. Place the cap on the
wheel and tap it into place until it seats ¯ush with the
wheel. The cap only goes on one way. Be sure to line up
the tab on the center cap with the indentation on the
wheel.
Storing a Flat or Spare Tire, Jack and
Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
Notice:Storing an aluminum wheel with a ¯at tire
under your vehicle for an extended period of time or
with the valve stem pointing up may damage the
wheel. Always stow the wheel with the valve
stem pointing down and have the wheel/tire repaired
as soon as possible.

8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the wheel
blocks) under the vehicle towards the front of the
rear bumper. Position the center lift point of the jack
under the center of the spare tire.
9. Turn the wrench clockwise to raise the jack until it
lifts the end ®tting.
10. Continue raising the jack until the spare tire stops
moving upward and is held ®rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.

Cleaning the Outside of Your
Vehicle
The paint ®nish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle's ®nish is to keep
it clean by washing it often with lukewarm or cold
water.
Don't wash your vehicle in the direct rays of the sun.
Use a car washing soap. Don't use strong soaps
or chemical detergents. Be sure to rinse the vehicle
well, removing all soap residue completely. You can get
GM-approved cleaning products from your dealer.
See
Vehicle Care/Appearance Materials on page 5-100.
Don't use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning agents
should be ¯ushed promptly and not allowed to dry on the
surface, or they could stain. Dry the ®nish with a soft,
clean chamois or an all-cotton towel to avoid surface
scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions under ªWashing Your Vehicle.º
Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint ®nish. You can get GM-approved cleaning products
from your dealer. See
Vehicle Care/Appearance
Materials on page 5-100.
If your vehicle has a ªbasecoat/clearcoatº paint ®nish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat paint
®nish.
