(3) Inspect the valve seat with Prussian blue to
determine where the valve contacts the seat. To do
this, coat valve seat LIGHTLY with Prussian blue
then set valve in place. Rotate the valve with light
pressure. If the blue is transferred to the center of
valve face, contact is satisfactory. If the blue is trans-
ferred to the top edge of valve face, lower valve seat
with a 15É stone. If the blue is transferred to bottom
edge of valve face raise valve seat with a 60É stone.
(4) When seat is properly positioned the width of
valve seats should be 1.016-1.524 mm (0.040-0.060
inch).
VALVE SPRING INSPECTION
Whenever valves have been removed for inspection,
reconditioning or replacement, valve springs should
be tested. As an example the compression length of
the spring to be tested is 1-5/16 inch. Turn table of
Universal Valve Spring Tester Tool until surface is in
line with the 1-5/16 inch mark on the threaded stud.
Be sure the zero mark is to the front (Fig. 19). Place
spring over stud on the table and lift compressing
lever to set tone device. Pull on torque wrench until
ping is heard. Take reading on torque wrench at this
instant. Multiply this reading by 2. This will give the
spring load at test length. Fractional measurements
are indicated on the table for finer adjustments.
Refer to specifications to obtain specified height and
allowable tensions. Discard the springs that do not
meet specifications.

ROLLOVER VALVE
DESCRIPTION
Diesel Powered Engine:One rollover valve is
used. The rollover valve is located on the top of the
fuel tank module (Fig. 49). The valve may be serviced
separately.
Gasoline Powered Engines:If equipped with a
26 or 34 gallon fuel tank, two rollover valves are
used. One of the valves is permanently mounted to
the top of fuel tank (Fig. 50). If replacement of this
particular valve is necessary, the fuel tank must be
replaced. The other rollover valve is located on the
top of the fuel pump module (Fig. 50). This valve
may be serviced separately. If replacement is neces-
sary, refer to the Removal/Installation section of this
group.
If equipped with a 35 gallon fuel tank, two rollover
valves are used. Both valves are permanently
mounted to the top of fuel tank (Fig. 51). If replace-
ment is necessary, the fuel tank must be replaced.

CAUTION: Do not allow the ohmmeter to contact
terminals 85 or 86 during these tests. Damage to
ohmmeter may result.
(7) Attach the other jumper wire (12V +) to termi-
nal number 86. This will activate the relay. Continu-
ity should now be present between terminals number
87 and 30. Continuity should not be present between
terminals number 87A and 30.
(8) Disconnect jumper wires from relay and 12 Volt
power source.
(9) If continuity or resistance tests did not pass,
replace relay. If tests passed, refer to 8, Wiring Dia-
grams for (fuel system) relay wiring schematics and
for additional circuit information.
REMOVAL
The fuel heater relay is located in the Power Dis-
tribution Center (PDC) (Fig. 13). Refer to label under
PDC cover for relay location.
(1) Remove PDC cover.
(2) Remove relay from PDC.
(3) Check condition of relay terminals and PDC
connector terminals for damage or corrosion. Repair
if necessary before installing relay.
(4) Check for pin height (pin height should be the
same for all terminals within the PDC connector).
Repair if necessary before installing relay.
INSTALLATION
The fuel heater relay is located in the Power Dis-
tribution Center (PDC) (Fig. 13). Refer to label under
PDC cover for relay location.
(1) Install relay to PDC.
(2) Install cover to PDC.
FUEL INJECTION PUMP
DESCRIPTIONÐFUEL PUMP 245 H.P.
Although the fuel injection pump on the 245 horse-
power engine appears similar to other VP 44 injec-
tion pumps, there are internal differences that make
it unique. If pump replacement is necessary, be sure
to verify pump number. The pump number can be
found on the Fuel Injection Pump Data Plate (Fig.
14).

CAUTION: The high-pressure fuel lines must be
clamped securely in place in the holders. The lines
cannot contact each other or other components. Do
not attempt to weld high-pressure fuel lines or to
repair lines that are damaged. Only use the recom-
mended lines when replacement of high-pressure
fuel line is necessary.
REMOVAL
High-pressure lines are used between the fuel
injection pump and the fuel injectors only. All high-
pressure fuel lines are of the same length and inside
diameter. Correct high-pressure fuel line usage and
installation is critical to smooth engine operation.
CAUTION: Refer to Cleaning Fuel System Parts.
(1) Disconnect both negative battery cables from
both batteries. Cover and isolate ends of cables.
(2) Thoroughly clean fuel lines at cylinder head
and injection pump ends.
(3) Remove cable cover (Fig. 39). Cable cover is
attached with 2 Phillips screws, 2 plastic retention
clips and 2 push tabs (Fig. 39). Remove 2 Phillips
screws and carefully pry out 2 retention clips. After
clip removal, push rearward on front tab, and
upward on lower tab for cover removal.Do not
remove any cables at lever.
(4) Disconnect wiring harness (clip) at bottom of
Accelerator Pedal Position Sensor (APPS) mounting
bracket (Fig. 40).(5) Using 2 small screwdrivers, pry front wiring
clip (Fig. 41) from cable bracket housing. Position
wiring harness towards front of engine.

BODY
DESCRIPTION ± PUSH-IN FASTENERS
DaimlerChrysler Corporation uses many different
types of push-in fasteners to secure the interior and
exterior trim to the body. Most of these fasteners can
be reused to assemble the trim during various repair
procedures. At times, a push-in fastener cannot be
removed without damaging the fastener or the com-
ponent it is holding. If it is not possible to remove a
fastener without damaging a component or body, cut
or break the fastener and use a new one when
installing the component. Never pry or pound on a
plastic or pressed-board trim component. Using a
suitable fork-type prying device, pry the fastener
from the retaining hole behind the component being
removed. When installing, verify fastener alignment
with the retaining hole by hand. Push directly on or
over the fastener until it seats. Apply a low-force pull
to the panel to verify that it is secure.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges holding the component in
place.
DESCRIPTION ± LOCK CYLINDERS
Ignition, door, deck lid, and rear hatch lock cylin-
ders are all codable to the key. Lock barrels, tum-
blers, and tumbler springs are available to allow the
technician to change replacement locks cylinders to
match the customer's original key set. See the appro-
priate section in this manual for lock cylinder
removal. See the Moparž catalogue for part numbers
and lock coding procedures.
SAFETY PRECAUTIONS AND WARNINGS
WARNING: USE A OSHA APPROVED BREATHING
FILTER WHEN SPRAYING PAINT OR SOLVENTS IN
A CONFINED AREA. PERSONAL INJURY CAN
RESULT.
AVOID PROLONGED SKIN CONTACT WITH PETRO-
LEUM OR ALCOHOL ± BASED CLEANING SOL-
VENTS. PERSONAL INJURY CAN RESULT.
DO NOT STAND UNDER A HOISTED VEHICLE THAT
IS NOT PROPERLY SUPPORTED ON SAFETY
STANDS. PERSONAL INJURY CAN RESULT.
CAUTION: When holes must be drilled or punched
in an inner body panel, verify depth of space to the
outer body panel, electrical wiring, or other compo-
nents. Damage to vehicle can result.
Do not weld exterior panels unless combustible
material on the interior of vehicle is removed from
the repair area. Fire or hazardous conditions, can
result.
Always have a fire extinguisher ready for use when
welding.
Disconnect the negative (-) cable clamp from the
battery when servicing electrical components that
are live when the ignition is OFF. Damage to electri-
cal system can result.
Do not use abrasive chemicals or compounds on
painted surfaces. Damage to finish can result.
Do not use harsh alkaline based cleaning solvents
on painted or upholstered surfaces. Damage to fin-
ish or color can result.
Do not hammer or pound on plastic trim panel
when servicing interior trim. Plastic panels can
break.
