CHEVROLET BLAZER 2005 2.G Owners Manual

Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted
or corroded. If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts
for your vehicle.{CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-72for more
information.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash. Use another type of traction device
only if its manufacturer recommends it for use
on your vehicle and tire size combination and
road conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, re-adjust or remove the
device if it is contacting your vehicle, and do
not spin your wheels. If you do nd traction
devices that will t, install them on the
rear tires.

If a Tire Goes Flat
It’s unusual for a tire to “blowout” 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 “blowout,” 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.
5-71

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ashers.
{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.
When you have a at tire, use the following example as a
guide to assist you in the placement of wheel blocks.
The following information will tell you next how to use
the jack and change a tire.

Removing the Spare Tire and Tools
The jacking equipment you’ll need is stored along
the driver’s side inner rear quarter panel. In some cases,
you may have to remove the spare tire in order to
reach the jack.
The following instructions explain how to remove the
spare tire, depending on where it is mounted on
your vehicle. SeeSpare Tire on page 5-84.
1. Remove your jack cover by pulling up on the
latch(es) on the cover (C). Remove the wheel
blocks (D), jack (G) and wheel wrench (F).Notice:If you remove or restow a tire from/to the
storage position under the vehicle when it is
supported by a jack, you could damage the tire
and/or your vehicle. Always remove or restow a tire
when the vehicle is on the ground.
2. Remove the
underbody-mounted
spare by inserting
the chisel end of the
wheel wrench, on
an angle, into the hoist
shaft hole in the
rear bumper. Be sure
the chisel end of
the wheel wrench
connects into the
hoist shaft.
3. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench until
the spare tire has been completely lowered.
4. Tilt the retainer at the end of the cable and pull it
through the wheel opening.
5-73

5. Pull the tire out from under the vehicle.
Notice:If you drive away before the spare tire
cable has been reinstalled, you could damage your
vehicle. Always reinstall this cable before driving
your vehicle.
If you have an inside-mounted spare tire, the tire must be
removed in order to have access to the jack storage.
To remove an inside-mounted spare tire, reach into your
tire’s cover and unscrew the wing nut at the center of
the wheel. Remove it and the retainer. Unhook the
tire from the mounting bracket and remove the cover.
To remove a rear-mounted spare tire, rst make
sure that the carrier arm is fully-latched to the tailgate.
Then remove the spare tire cover.If you have this feature,
the locking wheel nut can
be removed by snapping
the rubber weather
cover off the face of the
lock case.
Insert the key and pull the
lock case straight off. It is
not necessary to turn
the key.
Put the spare tire near the at tire.
5-74

The tools you’ll be using include the jack (A) and wheel
wrench (B). Your vehicle may also have an optional
hub cap removal tool.
Removing the Flat Tire and
Installing the Spare Tire
Position the chisel end of your wheel wrench, or the hub
cap removal tool (if equipped), in the notch of the hub
cap and pry off the hub cap.
Some of the molded plastic hub caps have imitation
wheel nuts molded into them. The wheel wrench won’t
t these imitation nuts, so don’t try to remove them
with the socket end of the wheel wrench.
5-75

If you have individual wheel nut caps that cover each
nut, they must be removed in order to get to the wheel
nuts. Use the socket end of the wheel wrench to
remove the wheel nut caps.
Your wheel nut caps may attach your hub cap to the
wheel. Remove these wheel nut caps before you take off
the hub cap.1. Using the wheel wrench, loosen all the wheel nuts.
Don’t remove them yet.
2. Turn the jack handle clockwise to raise the jack
lift head.
3. Fit the jack into the appropriate hole nearest the
at tire.
5-76

A. Front Frame Hole
B. Rear Frame Hole (2-Door) or Spring Hanger
Hole (4-Door)
{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.
5-77

{CAUTION:
Raising your 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 t the
jack lift head into the proper location before
raising the vehicle.4. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare tire to
t underneath the wheel well.
5. Remove all the wheel nuts and take off 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.
