How to Add Coolant to the Radiator
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

3. Fill the radiator with the proper mix, up to the base -
of the filler neck.
4. Then fill the coolant recovery tank to the ADD mark.
5. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap off.

the level reaches the base of the filler neck.

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 every day driving
conditions, the clutch is not fully 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.
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 4‘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.
'!!!h CAUTION:
I
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. 'hrn 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. The
following steps will tell
you how to use the jack and
change a tire.

- Removing the Spare Tire and Tools
The jacking equipment you’ll need is stored by your
vehicle’s rear doors, along the passenger side wall.
Remove your jack cover by pulling
it away from the
side wall and down to release the tabs securing the top
‘ of the cover. Remove the wheel, blocks by turning the top nut
counterclockwise. Remove the nut and washer, then pull
the wheel blocks off the bolt. Push down on the bolt and
remove the hooked
end from the slot. Slide the jack
toward the front of the vehicle and lift it from the
mounting. Remove the extension and the ratchet from
the pouch.

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.
The ratchet has an UP side.
Your spare tire is stored underneath the rear
of your
vehicle.
You will use the ratchet and extension to lower
the spare tire.
5-25

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 counterclockwise to lower the spare tire
to the ground. Keep turning the ratchet until the spare
tire can be pulled out from under the vehicle.
5-26

When the tire has been
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: I
To help avoid vehicle damage, do not drive the
vehicle before cable is restored.
The tools you’ll be using include the jack (A), wheel
blocks
(B), extension (C) and ratchet (D).

Removing the Wheel Covers If you have a standard steel wheel, carefully pry along - the edge of the hub cap until it comes off. Be-carefu1,the
cap with your bare hands.
You
will have to take
off hub caps or wheel nut caps to rim edges may be sharp. try to the hub
reach your wheel
nuts.
If you have the styled steel wheel, loosen the plastic nut
caps with the ratchet and socket. Make sure the DOWN
side faces you.
To remove the hub cap from the aluminum wheel, fit the
flat end
of the extension into the notch. Then, remove
the center cap.
