The following information explains
how to repair or change a tire.
Tire Changing
Removing the Spare Tire and
Tools
If you have a cargo van or a
passenger van, the equipment you
will need is located in the passenger
side rear corner of the vehicle.
Remove the retaining wing bolt and
lift it off of the mounting bracket.If you have a van with the
15‐passenger seating arrangement,
the equipment you will need is
secured on the rear floor of the
passenger side of the vehicle.
To access the equipment, remove
the retaining wing bolt and lift it out
of the mounting bracket.

The tools you will be using include:
A. Jack
B. Jack Handle
C. Hoist Extension
D. Jack Handle Extension
E. Wheel Wrench
The spare tire is mounted in the rear
underbody of the vehicle.
You will use the hoist extension, the
jack handle extensions and the
wheel wrench to remove the
underbody‐mounted spare tire.To lower the spare tire from the
vehicle:
A. Spare Tire
B. Tire/Wheel Retainer
C. Hoist Cable
D. Hoist Assembly
E. Hoist Shaft
F. Jack Handle and Hoist
Extensions
G. Wheel Wrench
1. Assemble the wheel wrench (G) to one or two of the jack handle
and the hoist extensions (F).
Insert the hoist extension end
through the hole in the rear
bumper.
2. Be sure the hoist extension end connects to the hoist shaft (E).
The chiseled end of the
extension is used to lower the
spare tire.
3. 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
vehicle.

Vehicle Care 10-75
If the spare tire does not lower to
the ground, the secondary latch
is engaged causing the tire not
to lower. SeeSecondary Latch
System on page 10‑81.
4. When the tire has been lowered, pull the tire toward you
so you can reach the tire
retainer and pull it up through
the wheel opening.
If you have a vehicle which was
completed from a cab and
chassis, refer to the information
from body supplier/installer. The spare tire is a full‐size tire,
like the other tires on the
vehicle.
5. Put the spare tire near the flat tire.
Removing the Flat Tire and
Installing the Spare Tire
If the vehicle has plastic wheel nut
caps, loosen them by turning the
wheel wrench counterclockwise.
The wheel nut caps are designed to
remain with the center cap. Remove
the center cap.
If the wheel has a smooth center
piece, place the chisel end of the
wheel wrench in the slot on the
wheel and gently pry it out.
1. Do a safety check beforeproceeding. See If a Tire Goes
Flat on page 10‑71 for more
information.
2. Loosen all the wheel nuts with the wheel wrench. Do not
remove them yet. 3. Assemble the jack and tools:
Front Flat:
Assemble the
jack (A) together with the jack
handle (B), one or two jack
handle extensions (D) and the
wheel wrench (E).
Rear Flat: Assemble the jack (A)
together with the jack handle (B),
two jack handle extensions (D),
and the wheel wrench (E).

Front Position
Front Position
Rear Position
Rear Alternative Position (DieselVehicles) 4. Position the jack under the
vehicle as shown.
The front position jacking point is
on the frame. The rear position
jacking point is on the rear axle.
If the exhaust system interferes
in the jack location in the rear
axle, such as in Diesel vehicles,
place the jack (A) on the
rear axle between the axle
housing and the shock absorber
bracket in order to avoid any
interference with the exhaust
pipe (B).
{WARNING
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.

Vehicle Care 10-77
{WARNING
Raising 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.
5. Raise the vehicle by turning the wheel wrench clockwise. Raise
the vehicle far enough off the
ground so there is enough room
for the spare tire to fit.
6. Remove all the wheel nuts.
7. Take flat tire off of the mountingsurface.
{WARNING
Rust 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 an accident. When
changing a wheel, remove any
rust or dirt from places where the
(Continued)
WARNING (Continued)
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
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 thewheel bolts, mounting surfaces
and spare wheel.

10-78 Vehicle Care
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
9. Put the wheel nuts back on withthe rounded end of the nuts
toward the wheel. Tighten each
wheel nut by hand until the
wheel is held against the hub. 10. Lower the vehicle by turning
the jack handle
counterclockwise. Lower the
jack completely.
{WARNING
Wheel nuts that are not tight can
work loose. If all the nuts on a
wheel come off, the wheel can
come off the vehicle, causing a
crash. All wheel nuts must be
properly tightened. Follow the
rules in this section to be sure
they are.
{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.
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.

Vehicle Care 10-79
{WARNING
Wheel 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. SeeCapacities and
Specifications on page 12‑2 for
original equipment wheel nut
torque specifications.
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 specification. See
Capacities and Specifications on
page 12‑2 for the wheel nut
torque specification.
11. Use the wheel wrench to tighten the nuts firmly. Turn the
wheel wrench clockwise and in
a crisscross sequence as
shown. 12. Put the wheel cover or the
center cap and plastic wheel
nut caps back on. Remove any
wheel blocks.
Have a technician check the
wheel nut tightness of all
wheels with a torque wrench
after the first 160 km
(100 miles) and then 1600 km
(1,000 miles) after that. Repeat
this service whenever you have
a tire removed or serviced. See
Capacities and Specifications
on page 12‑2 for more
information.

Storing a Flat or Spare Tire
and Tools
{WARNING
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.
1. Put the tire on the ground at the rear of the vehicle with the valve
stem pointed down.
2. Pull the retaining bar through thecenter of the wheel, making sure
it is properly attached.
3. Pull the wheel toward the rear of the vehicle, keeping the cable
tight.
4. Put the chisel end of the hoist extension on an angle through
the hole in the rear door frame,
above the bumper.
5. Raise the tire fully against the underside of the vehicle.
Continue turning the wheel
wrench until the tire is secure and the cable is tight. The spare
tire hoist cannot be
overtightened.
6. Make sure the tire is stored
securely. Push, pull (A), and then
try to turn (B) the tire. If the tire
moves, use the wheel wrench to
tighten the cable.
You will hear two clicks when the
tire is up all the way.
7. Return the jacking equipment to the proper location. Secure the
items and replace the jack cover.
