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.)
4. Then fill the coolant recovery tank to the
COLD mark.
5. Put the cap back on the coolant recovery tank, but

6.
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.
8. Then replace the pressure cap. At any time during
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 If a Tire Goes Flat
Your 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 fan is spinning slower and
the clutch is not fully
engaged. This improves
fuel economy and reduces fan
noise. Under heavy vehicle loading, trailer towing andor
high outside temperatures,
the fan speed increases as the
clutch more fully 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 partially disengages.
You may also hear this fan noise when you start
the engine. It will go away as
the fan clutch
partially disengages. 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.
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.
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.
-
CAUTION:
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 the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put 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. The
following steps will tell you how to use the
jack and
change a tire.

Removing the Spare Tire and Tools
Your spare tire is stored underneath the rear of your
vehicle.
You will use the ratchet and extension to lower
the spare tire.
A flat rear tire reduces clearance to remove the spare
tire.
If there is less than 12 inches (30.48 cm) between
the ground and the rear bumper or any trailer hitch, jack
up the vehicle until the flat tire is off the ground. (See
“Removing the Flat Tire” and “Installing the Spare
Tire,” Steps
4 through 8, in this section.) Unless your vehicle has
a flat rear tire, do not remove
or restore a tire fromho
a storage position under the
vehicle while the vehicle is supported by a jack. Always
tighten
the tire fully against the underside of the vehicle
when restoring.
If you have a vehicle which was completed from a cab
and chassis, refer to the information from the body
supplierhnstaller.
The spare tire is a
full size tire, like the other tires on
your vehicle.
Remove the retaining wing bolt and lift it off the
mounting bracket. Set the jack and jacking equipment
near the flat tire.

ProCarManuals.com

For vans with the 15-passenger seating arrangement,
the jack
is secured on the rear passenger side floor of
the vehicle.
Remove the retaining wing bolt and lift it out
of the
mounting bracket. Set the jack and jacking equipment
near
the flat tire.
I
The ratchet has a DOWN side and an UP side.
Attach the ratchet, with
the DOWN side facing you, to
the extension. The extension has a socket end and a flat
chisel end.
Put the flat end
of the extension on an angle through the
hole in the rear door frame, above the bumper. Be sure
the flat end connects into the hoist shaft.

Turn the ratchet to the left to lower the spare tire to the
ground. If you
are changing a flat rear tire and the
vehicle is already jacked up, use the jack handle and
extension to hook the cable. Then pull the spare from
beneath the vehicle. If the retainer pulls out, hook the
inside
of the wheel and pull the spare tire out from under
the vehicle.
When the tire has been lowered, tilt the retainer at the
end of the cable and pull it through the wheel opening.
I NOTICE: I
To help avoid vehicle damage, do not drive
vehicle before the cable is restored.
