1998 Oldsmobile Achieva Owner's Manuals

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.
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
fit the jack
lift head into the proper location before raising
the vehicle.
5. Raise the vehicle by rotating the wheel wrench to the
right. Raise the vehicle far enough off the ground
so
there is enough room for the spare tire to fit.
6. Remove all of the wheel nuts.
5-29

8. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
7. Remove the wheel cover from the wheel, if your
vehicle has them. Then take off the flat tire.

I'
I A 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.
A 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.
9. Replace the wheel
nuts with the cone
end
of the nuts
toward the wheel.
Tighten each nut
by
hand or with the
wheel wrench until
the wheel
is held
against the hub.

1. C! UTldN:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become 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 100 lb-ft
(140 N-m).
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.
I NOTICE: I
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be 60 psi
(420 Wa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact spare
is made to perform well at speeds up to 65 mph
(105
km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where you want. Of course, it’s best
to replace your spare with a full-size tire as soon as you
can. Your spare will last longer and
be in good shape in
case you need it again.
NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
