BUMPERS
DESCRIPTION
Bumpers are used at the front and rear of the
vehicle. Bumpers may be chrome or painted.
Bumpers are designed to protect the exterior sheet-
metal in low impact situations. The bumpers are
attached to the frame and provide mounting points
for some optional accessories such as fog lights and
tow hooks.
FRONT AIR DAM
REMOVAL
(1) Remove Pin-type fasteners attaching air dam
to bottom of front bumper (Fig. 1).
(2) Remove screws attaching air dam to bottom of
front bumper.
(3) Separate air dam from bumper.
BR/BEFRAME & BUMPERS 13 - 1

(e) Connect electrical connector to WIF sensor.
(f) Install fuel filter. Refer to previous steps.
(4)Fuel Heater Element:
(a) Do not install fuel filter until heater element
is installed.
(b) Position heater element into filter housing
(fingers downward). Lock fingers into housing.
(c) Install new o-ring to electrical connector
(where connector passes through filter housing).
Apply a light film of clean diesel oil to o-ring seal.
Press this connector into filter housing until it
snaps into heater element.
(d) Install temperature sensor housing and 2
mounting screws to fuel filter housing.
(e) Connect electrical connector.
(f) Install fuel filter. Refer to previous steps.
(5)Drain Valve:
(a) Install 2 new o-rings to valve and filter hous-
ing.
(b) Apply a light film of clean diesel oil to both
seals.
(c) Position valve to filter housing.
(d) Install 4 mounting screws and tighten to 3±5
N´m (30±40 in. lbs.) torque.
(e) Connect drain hose to drain valve.
(f) Install fuel filter. Refer to previous steps.
(6) Start engine and check for leaks.
FUEL HEATER
DESCRIPTION
The fuel heater assembly is located on the side of
the fuel filter housing (Fig. 9).
The heater/element assembly is equipped with a
temperature sensor (thermostat) that senses fuel
temperature. This sensor is attached to the fuel heat-
er/element assembly.
OPERATION
The fuel heater is used to prevent diesel fuel from
waxing during cold weather operation.
When the temperature is below 4568 degrees F,
the temperature sensor allows current to flow to the
heater element warming the fuel. When the temper-
ature is above 7568 degrees F, the sensor stops cur-
rent flow to the heater element.
Battery voltage to operate the fuel heater element
is supplied from the ignition switch and through the
fuel heater relay. Also refer to Fuel Heater Relay.
The fuel heater element and fuel heater relay
are not computer controlled.
The heater element operates on 12 volts, 300 watts
at 0 degrees F.
DIAGNOSIS AND TESTING - FUEL HEATER
The fuel heater is used to prevent diesel fuel from
waxing during cold weather operation.
NOTE: The fuel heater element, fuel heater relay
and fuel heater temperature sensor are not con-
trolled by the Powertrain Control Module (PCM).
A malfunctioning fuel heater can cause a wax
build-up in the fuel filter/water separator. Wax
build-up in the filter/separator can cause engine
starting problems and prevent the engine from rev-
ving up. It can also cause blue or white fog-like
exhaust. If the heater is not operating in cold tem-
peratures, the engine may not operate due to fuel
waxing.
The fuel heater assembly is located on the side of
the fuel filter housing (Fig. 10).
The heater assembly is equipped with a built-in
fuel temperature sensor (thermostat) that senses fuel
temperature. When fuel temperature drops below 45
degrees68 degrees F, the sensor allows current to
flow to the built-in heater element to warm the fuel.
When fuel temperature rises above 75 degrees68
degrees F, the sensor stops current flow to the heater
element (circuit is open).

BODY INTERIOR
INSPECTION - COMPASS
NOTE: Set variance after calibration.
(1) Calibrate and set compass variance (Fig. 26), if
so equipped (use appropriate procedures in service
information).
(2) Remove protective film from overhead console,
if equipped.
INSPECTION - FIT AND FINISH
(1) Remove any interior covers.
(2) Inspect the instrument panel, glove box door
(Fig. 27) and interior moldings for even gaps and
alignments.
(3) Check that the door panel material is clean,
free from wrinkles and installed correctly.
(4) Check that the seat material is clean, secure
and free of wrinkles.
(5) Check that the carpet is clean, secure and free
of wrinkles.
(6) Check that the headliner is clean, free of lint
and dirt smudges.
INSPECTION - LIGHTS AND SWITCHES
(1) Remove protective film from all switch bezels.
(2) Operate and visually inspect all interior lights
and switches, including:
²Dome/map lamps
²Vanity mirror lamps
²Glove box light²Ashtray light
²Cigar lighter light
²All gauge lights
²Radio display
²Door-mounted lights, if equipped
²Illuminated entry system, if equipped
(3) Visually inspect and operate all exterior lights
and their switches, including:
NOTE: Headlamp aim is preset during vehicle
assembly.
²Headlights, including high beam, optical horn
(ªflash to passº) and daylight running lamps (DRL's)
(Fig. 28)
²Tail/stop lamps (including center high-mounted
stop lamp)
²Parking lights Turn signals Brake lights (includ-
ing center high mounted stop lamp)
²Emergency flashers (Fig. 29)
²Fog/driving lights, if equipped
²Off-road or other lights, if equipped
²Cargo bed lights, if equipped
(4) Check ignition switch for proper operation in
all positions (accessory, lock, on, start and off).
INSPECTION - SEAT BELTS, SHOULDER
BELTS, RETRACTORS AND HEAD RESTRAINTS
(1) Inspect all seat belts and harnesses to ensure
that they connect and hold properly.
(2) Inspect the condition of the belts and anchors.
(3) Inspect for proper seat belt retraction.
