IN CASE OF EMERGENCY341

1. If equipped, remove the spare wheel, jack,
and tools from storage.

2. Using the lug wrench, loosen, but do not remove, the lug nuts by turning them
counterclockwise one turn while the wheel
is still on the ground.
3. When changing the front wheel, assemble the jack driver to the jack and connect the
jack driver to the extension tube. Place the
jack under the axle as close to the tire as
possible with the jack driver extending to
the front. Connect the extension tubes and
lug wrench.
Front Jacking Locations

When changing a rear wheel, assemble the
jack driver to the jack and connect the jack
driver to the extension tubes. Securely
place the jack under the sway bar bracket
(unless both tires are flat on one side, then
place jack under shock bracket) facing for -
ward in vehicle. Connect the extension
tubes and lug wrench.
Rear Jacking Location

Before raising the wheel off the ground,
make sure that the jack will not damage
surrounding truck parts and adjust the jack
position as required.
NOTE:
If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to
use the jack driver in order to lower the jack.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the
surface.
CAUTION!
Do not attempt to raise the vehicle by jacking
on locations other than those indicated in the
Jacking Instructions for this vehicle.

SERVICING AND MAINTENANCE375
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools, we recommend having your
vehicle serviced at an authorized dealer.
DRAINING FUEL/WATER SEPARATOR
F
ILTER
There are two fuel filter assemblies. One is
located on the driver's side of the engine.
The best access to this water drain valve is from
under the hood. The second one is on the under
body, located in front of the rear axle above the
drive shaft on pick-up models. The Chassis Cab
models second filter location is on the frame
behind the front axle. The best access to this
water drain valve is from under the vehicle. If water is detected in the water separator while
the engine is running, or while the ignition
switch is in the ON position, the “Water In Fuel
Indicator Light” will illuminate and an audible
chime will be heard five times. At this point you
should stop the engine and drain the water from
both of the filters.
If the “Water In Fuel Indicator Light” comes on
and a single chime is heard while you are
driving, or with the ignition switch in the ON
position, there may be a problem with your
water separator wiring or sensor. See an
authorized dealer for service.
Upon proper draining of the water from both
fuel filters, the “Water In Fuel Indicator Light”
will remain illuminated for approximately
10 seconds. If the water was drained while
the engine was running, the “Water In Fuel
Indicator Light” may remain on for
approximately three minutes.NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the envi
-
ronment. Contact an authorized dealer, service
station, or government agency for advice on
recycling programs and for where used fluids
and filters can be properly disposed of in your
area.

Drain the fuel/water separator filters when the
“Water In Fuel Indicator Light” is ON. Within
10 minutes of vehicle shutdown, turn the engine
mounted filter drain valve (located on the side of
the filter assembly) counterclockwise a quarter
turn, and turn the under body mounted filter
drain valve (located on the bottom of the filter
assembly) counterclockwise 1 full turn. Then turn
the ignition switch to the ON position, and allow
any accumulated water to drain. Leave the drain
valve open until all water and contaminants have
been removed. When clean fuel is visible, close
the drain valve following these guidelines:

1. Rotate the drain clockwise to close until you feel resistance from the internal seal.

2. Continue turning the drain half of a turn to properly compress the seal.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
CAUTION!
If the “Water In Fuel Indicator Light” remains
on, DO NOT START the engine before you
drain water from the fuel filters to avoid
engine damage.

376SERVICING AND MAINTENANCE
NOTE:
Over-compression of the seal due to over-tight -
ening of the drain will damage the seal, cause
a leak, and require the entire sensor to be
replaced.
3. Turn the ignition switch to OFF.
The sensor drain should not be over-tightened
during normal service operations to avoid
internal damage and future fuel leaks.
The drain should be closed and secured
without the use of tools.
If more than a couple ounces/milliliters of fuel
have been drained, follow the directions for
“Priming If The Engine Has Run Out Of Fuel”

NOTE:
Using a fuel filter that does not meet the
manufacturer's filtration and water sepa -
rating requirements can severely impact fuel
system life and reliability.
The engine mounted filter housing is
equipped with a No-Filter-No-Run (NFNR)
feature. Engine will not run if:
a. No filter is installed.
b. Inferior/Non-approved filter is used. Use of OEM filter is required to ensure
vehicle will run.

CAUTION!
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
Do not prefill the fuel filter when installing a
new fuel filter. There is a possibility debris
could be introduced into the fuel filter
during this action. It is best to install the
filter dry and allow the in-tank lift pump to
prime the fuel system.
