Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutc\
h is engaged,
the fan spins faster
to provide more air to cool the engine. In most every day
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 e\
ngages.
So
you may hear an increase in fan noise. This is normal and sh\
ould 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 Fiat
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, 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 co\
ntrol 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 your 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
injured. Find a level place to change your tire. To help prevent the
vehicle
from moving:
- and roll over you or other people. You and they could be badly
1. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. Shift a manual transmission to 1 (First) or R (Reverse).
4. If you have a four-wheel-drive vehicle, be sure the transfer case \
5. Turn off the engine.
is in a drive gear-not in N (Neutral).
To be even more certain the vehicle won't move, you can put chocks
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.

To take the jack out, turn the wing nut counterclockwise and take it and the
retainer
off. Take the jack and storage box out and take the tools out of the
box.
Your vehicle may have a pair
of emergency gloves secured to the jack. You
can use them when changing the tire, or during other emergency situations.
Remember to replace them with the jack,
so you will have them handy if
needed later.

K2519
Start with the jack, the jack handle and the ratchet. If the flat tire is on the

K2521
Attach the jack handle (and jack handle extensions, if needed) to the jack.
With the
UP marking on the ratchet facing you, rotate the ratchet clockwise.
That
will lift the jack head a little. Before raising the vehicle, do the following
things.
Put
your spare tire near the flat tire.
Remove the wheel trim.

If there is a wheel cover, remove it by using the flat end of the socket. Pry
along the edge
of the wheel cover until it comes off. Be careful; the rim
edges may be sharp. Don't try to remove
it with your bare hands.

CAUTION
I A Getting under a vehicle when it is jacked up is dangerous. If the I
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. I

PO288
Raise the vehicle by rotating the ratchet clockwise. Make sure \
the UP
marking faces you. Use the jack handle extensions if the flat \
tire is on the
rear
of the vehicle. Raise the vehicle far enough off the ground so there is
enough room for the spare tire
to fit.

CAUTION I
Incorrect wheel nuts or improperly tightened wheel nuts can cau\
se
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 the right kind.
Stop somewhere as soon as you can and have the nuts tightened
with a torque wrench
to the promr toraue. I
For proper torque, see “Wheel Nut Torque” in the Index.
Put the wheel trim back on. For vehicles with plastic nut cap\
s, tighten the
caps until they are finger tight, then tighten them an additio\
nal one-half turn
with the ratchet. Remove any wheel blocks.
Storing
a jack, a tire or other equipment in the passenger
compartment
of the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone. Store all these\
in
the proper place.
