on location.1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap
and upper radiator hose, is no longer hot. Turn
the pressure cap slowly counterclockwise until it
first stops. (Don't press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.

the pressure cap,

as you turn it.
Remove the
pressure cap.

1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.

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.

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 jack handle
clockwise. Raise the vehicle far enough off the
ground for the spare tire to fit under the vehicle.
6. Remove all wheel nuts and take off the flat tire.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
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.
