Downloaded from www.Manualslib.com manuals search engine Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap,
is hot. Wait for the cooling system and
radiator pressure cap to cool
if you ever have to
turn the pressure cap.
J- IW to Add Coolant to the Radiator
1. You can remove the pressure cap when the cooling
system, including the 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.

down as
you turn it. Remove the pressure cap.
3. Fill the radiator with the proper DEX-COOL@
coolant mixture, up to the base of the filler neck.
(See “Engine Coolant” in the Index
for more
information about the proper coolant mixture.)

5. Put the cap back on the coolant recovery tank, but
leave the pressure cap off.

7.
Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper
DEX-COOL@ coolant mixture
through the filler neck
until the level reaches the
base
of the filler neck.

this procedure if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows on the pressure cap line
up like this.
Engine Fan Noise
This vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster
to provide
more air to cool the engine.
In most everyday driving
conditions, the clutch is not engaged. This improves fuel
economy and reduces fan noise. Under heavy vehicle
loading, trailer towing and/or high outside temperatures,
the fan speed increases when the clutch engages.
So you
may hear an increase
in fan noise. This is normal and
should
not be mistaken as the transmission slipping or
making extra shifts. It is merely the cooling system
functioning properly. The fan will slow down when
additional cooling is
not required and the
clutch disengages.
You may also hear this fan noise when you start the
engine. It will go away
as the fan clutch disengages.

Downloaded from www.Manualslib.com manuals search engine If a Tire Goes Flat
It’s unusual for a tire to “blow out” 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 flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out
of the traffic lane.
H 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.
If a tire goes flat, the
next part shows how to use your
jacking equipment to change
a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place.
Turn on your hazard
warning flashers.
Changing a tire can cause an injury, The vehicle
can slip
off the jack and roll over you or other
people.
You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift
lever in PARK
(P) or shift a manual
transmission
to FIRST (1) or
REVERSE (R).
3. Thrn off the engine.
4. 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 of the vehicle, at
the opposite end.

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 panels.
In some cases,
you may have to remove the spare tire in order to reach
the jack. Your vehicle is
also equipped with work gloves
and a plastic ground mat
to assist in the changing of a
flat tire. The following instructions explain how
to remove the
spare tire, depending on where
it is mounted on
your vehicle.
I NOTICE:
Never remove or restow a tire frondto a stowage
position under the vehicle while the vehicle is supported
by a jack. Always tighten the tire
fully against the underside of the vehicle
when restowing.

Downloaded from www.Manualslib.com manuals search engine To remove the
underbody-mounted spare,
insert the chisel end of the
wheel wrench,
on an angle,
into the hole
in the rear
bumper. Be sure the chisel
end
of the wheel wrench
connects into the hoist shaft.
Turn the wheel wrench to the left to lower the spare tire.
Keep turning the wheel wrench until the spare tire can
be pulled
out from under the vehicle.
When the tire
has been completely lowered, tilt the
retainer
at the end of the cable and pull it through the
wheel opening.
Pull the tire out from under the vehicle.
I NOTICE:
- ~~
To help avoid vehicle damage, do not drive the
vehicle before the cable
is properly stored.
If you have an inside-mounted spare tire, the tire must
be removed
in order to have access to the jack storage.
10 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, first make sure
that the carrier arm is fully-latched
to the endgate. Then
remove the spare tire cover.
