(open end) (F) of the

the hole (G) in
the rear bumper.
Be sure the hoist end of the extension (F)
connects to the hoist shaft (E). The ribbed
square end of the extension is used to lower

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. SeeSecondary Latch
System on page 592.5. Use the wheel
wrench hook which
allows you to
pull the hoist cable
towards you to
assist in reaching
the spare tire.

Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to
remove the at tire and raise the vehicle.
The tools you will be using include the jack (A),
the wheel blocks (B), the jack handle (C), the jack
handle extensions (D), and the wheel wrench (E).1. If your 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.

{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time. The
CAUTION: (Continued)
CAUTION: (Continued)
wheel could come off and cause an
accident. When changing a wheel, remove
any rust or dirt from the places where the
wheel attaches to the vehicle. In an
emergency, a cloth or a paper towel can
be used to do this; but be sure to use a
scraper or wire brush later, if needed, to
get all the rust or dirt off.
6. Remove any rust or

{CAUTION:
Never use oil or grease on studs or nuts.
Because the nuts might come loose. The
vehicle’s wheel could fall off, causing a
serious accident.
8. Put the wheel nuts back on with the rounded
end of the nuts toward the wheel.
9. Tighten each wheel nut by hand. Then use
the wheel wrench to tighten the nuts until the
wheel is held against the hub.
10. Turn the wheel wrench counterclockwise to
lower the vehicle. Lower the jack completely.
{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 specication. See
Capacities and Specifications on page 620
for wheel nut torque specication.
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 specication. SeeCapacities
and Specifications on page 620for the wheel
nut torque specication.

11. Tighten the nuts rmly in a crisscross
sequence as shown by turning the wheel
wrench clockwise.
When you reinstall the regular wheel and tire, you
must also reinstall either the center cap, or
bolt-on hub cap, depending on what your vehicle
is equipped with. For center caps, 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. 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.
Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly which has a secondary latch system.
It is designed to stop the spare tire from suddenly
falling off your vehicle. For the secondary latch
to work, the spare tire must be installed with
the valve stem pointing down. SeeStoring a Flat
or Spare Tire and Tools on page 596.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.
