in the ON position, there may be a problem with your
water separator wiring or sensor. See your authorized
dealer for service.
Upon proper draining of the water from the fuel filter, 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 environment. 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 filter when the “Water In
Fuel Indicator Light” is ON. Within 10 minutes of vehicle
shutdown, turn the filter drain valve (located on the
bottom of the filter housing) counterclockwise to drain
fuel/water, then turn the ignition switch to the ON posi-
tion, 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 by turning it clockwise, and turn the ignition switch
to OFF. If more than two ounces or 60 milliliters of fuel have been
drained, follow the directions for “Priming If The Engine
Has Run Out Of Fuel.”
Underbody Mounted Fuel Filter Replacement
NOTE:
Using a fuel filter that does not meet the manufac-
turer’s filtration and water separating requirements can
severely impact fuel system life and reliability.
CAUTION!
• Diesel fuel will damage blacktop paving surfaces.
Drain the filter into an appropriate 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.

1 — Water in Fuel Drain
2 — Fuel Filter Access
1. Turn engine off.
2. Place a drain pan under the fuel filter assembly.
3. Open the water drain valve, and let any accumulated water drain.
4. Close the water drain valve. 5. Remove bottom cover using a strap wrench. Rotate
counterclockwise for removal. Remove the used o-ring
and discard it.
6. Remove the used filter cartridge from the housing and dispose of it according to your local regulations.
7. Wipe the sealing surfaces of the lid and housing clean.
8. Install a new o-ring into the ring groove on the filter housing and lubricate with clean engine oil.
NOTE: WIF (Water In Fuel) sensor is re-usable. Service kit
comes with new o-ring for filter canister and WIF sensor.
Priming If The Engine Has Run Out Of Fuel
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).

2. Press ignition switch twice without your foot on braketo put vehicle in Run position. This will activate the in
tank fuel pump for approximately 30 seconds. Repeat
this process twice.
3. Start the engine using the “Normal Starting” procedure. Refer to “Starting Procedures” in “Starting and Operat-
ing” for further information.
CAUTION!
The starter motor will engage for approximately 30
seconds at a time. Allow two minutes between crank-
ing intervals.
NOTE: The engine may run rough until the air is forced
from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel blending agent.
They can be unstable under certain conditions and be
hazardous or explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the use
of these fuels can cause damage to the fuel system.
NOTE:
• Use of biodiesel mixture in excess of 20% can negatively
impact the fuel filter’s ability to separate water from the
fuel, resulting in high pressure fuel system corrosion or
damage.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your diesel
engine.
• For extreme cold conditions, Mopar Premium Diesel
Fuel Treatment is recommended to assist with cold
starting.

Engine Coolant We recommend you use MOPAR Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology).
Engine Oil We recommend you use 5W-40 syntheticengine oil such as MOPAR or Shell Rotella that meets
FCA Material Standard MS-10902 and the API CJ-4 engine oil category is required.
Engine Oil Filter We recommend you use MOPAR Engine Oil Filters.
Fuel Filters We recommend you use MOPAR Fuel Filter. Must meet 3 micron rating. Using a fuel filter that
does not meet the manufacturers filtration and water separating requirements can severely
impact fuel system life and reliability.

Required Maintenance
Refer to the Maintenance Schedules on the following pages
for required maintenance.
At Every Oil Change Interval As Indicated By OilChange Indicator System:
•Change oil and filter.
• Completely fill the Diesel Exhaust Fluid tank.
• Drain water from fuel filter assembly.
• Rotate the tires. Rotate at the first sign of irregular
wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
