end) (10) of the extension
through the hole (9) in the rear
bumper.
Do not use the chiseled end of
the wheel wrench.
Be sure the hoist end of the
extension (10) connects to the
hoist shaft. The ribbed square
end of the extension is used to
lower the spare tire.
4. Turn the wheel wrench
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

Removing the Flat Tire and
Installing the Spare Tire Use the following pictures and
instructions to remove the flat tire
and raise the vehicle.
1. Jack
2. Wheel Blocks
3. Jack Handle 4. Jack Handle Extensions
5. Wheel Wrench
The tools you will be using include
the jack (1), the wheel blocks (2),
the jack handle (3), the jack handle
extensions (4), and the wheel
wrench (5).
1. Do a safety check before
proceeding. See If a Tire Goes
Flat 0 383 .
2. If the vehicle has wheel nut
caps, loosen them by turning
the wheel wrench
counterclockwise. If the vehicle has a center cap
with wheel nut caps, the wheel
nut caps are designed to stay
with the center cap after they
are loosened. Remove the
entire center cap.
If the wheel has a smooth
center cap, place the chisel
end of the wheel wrench in the
slot on the wheel, and gently
pry it out.

3. Use the wheel wrench and turn
it counterclockwise to loosen
the wheel nuts. Do not remove
the wheel nuts yet. Front Position
4. If the flat tire is on the front of
the vehicle, position the jack
under the bracket attached to
the vehicle's frame, behind the
flat tire, as shown. Rear Position
5. If the flat tire is on the rear,
position the jack under the rear
axle about 5 cm (2 in) inboard
of the shock absorber bracket.
{ Warning
Getting under a vehicle when it is
lifted on a jack 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.

{ WarningRaising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.
6. Turn the wheel wrench
clockwise to raise the vehicle.
Raise the vehicle far enough
off the ground so there is
enough room for the spare tire
to fit under the wheel well. 7. Remove all the wheel nuts and
take off the flat tire.
{ WarningRust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause a crash. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
(Continued) Warning (Continued) towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
8. Remove any rust or dirt from
the wheel bolts, mounting
surfaces, and spare wheel.
9. Install the spare tire.

{ WarningNever use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
10. Put the wheel nuts back on
with the rounded end of the
nuts toward the wheel.
11. Tighten each wheel nut by
hand. Then use the wheel
wrench to tighten the nuts until
the wheel is held against
the hub.
12. Turn the wheel wrench
counterclockwise to lower the
vehicle. Lower the jack
completely.
{ Warning
If wheel studs are damaged, they
can break. If all the studs on a
wheel broke, the wheel could
come off and cause a crash.
(Continued) Warning (Continued) If any stud is damaged because
of a loose-running wheel, it could
be that all of the studs are
damaged. To be sure, replace all
studs on the wheel. If the stud
holes in a wheel have become
larger, the wheel could collapse in
operation. Replace any wheel if
its stud holes have become larger
or distorted in any way. Inspect
hubs and hub ‐ piloted wheels for
damage. Because of loose
running wheels, piloting pad
damage may occur and require
replacement of the entire hub, for
proper centering of the wheels.
When replacing studs, hubs,
wheel nuts or wheels, be sure to
use GM original equipment parts. { WarningWheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. See Capacities and
Specifications 0 430 for original
equipment wheel nut torque
specifications.
Caution
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

Capacities and Specifications
0 430 for the wheel nut torque
specification.
13. Tighten the nuts firmly in a
crisscross sequence, as
shown, by turning the wheel
wrench clockwise.
When reinstalling the regular wheel
and tire, also reinstall either the
center cap, or bolt-on hub cap,
depending on what the vehicle is equipped with. For center caps,
place the cap on the wheel and tap
it into place until it seats flush 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. For
bolt-on hub caps, align the plastic
nut caps with the wheel nuts and
then tighten by hand. Then use the
wheel wrench to tighten.
Storing a Flat or Spare Tire
and Tools
{ WarningStoring 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. { WarningFailure to follow these tire storage
instructions carefully could result
in personal injury or property
damage if the hoist cable fails or
if the tire comes loose. Make sure
the tire is stored securely before
driving.
CautionStoring an aluminum wheel with a
flat tire under your vehicle for an
extended period of time or with
the valve stem pointing up can
damage the wheel. Always stow
the wheel with the valve stem
pointing down and have the
wheel/tire repaired as soon as
possible.

392 Vehicle Care CautionThe tire hoist can be damaged if
there is no tension on the cable
when using it. To have the
necessary tension, the spare or
road tire and wheel assembly
must be installed on the tire hoist
to use it.
{ WarningAn improperly stored spare tire
could come loose and cause a
crash. To avoid personal injury or
property damage, always store
the spare tire when the vehicle is
parked on a level surface.
