Engine Air Cleaner Filter
WARNING!
The air induction system (air cleaner,
hoses, etc.) can provide a measure of pro-
tection in the case of engine backfire. Do
not remove the air induction system (air
cleaner, hoses, etc.) unless such removal
is necessary for repair or maintenance.

result in serious personal injury.
CAUTION!
All air entering the engine intake must be
filtered. The abrasive particles in unfil-
tered air will cause rapid wear to engine
components.
Refer to the “Maintenance Plan” for the
proper maintenance intervals.
CAUTION!
Many aftermarket performance air filter
elements do not adequately filter the air
entering the engine. Use of such filters can
severely damage your engine.
Draining Fuel/Water Separator
Filter
The fuel filter/water separator filter housing is
located above the rear axle next to the fuel
tank. The best access to this water drain valve
is from under the vehicle.
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.
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 illumi-
249

nate and an audible chime will be heard. At
this point, you should stop the engine and
drain the water from the filter housing.
CAUTION!
If the “Water In Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain water from the fuel filter to
avoid engine damage.
If the “Water In Fuel Indicator Light” comes
on and a single chime is heard while you are
driving, or with the ignition in the ON posi-
tion, there may be a problem with your water
separator wiring or sensor. See your autho-
rized 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 approxi-
mately three minutes. NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately 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
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 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
manufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
CAUTION!
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
• Do not prefill the fuel filter when install-
ing 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. 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.

WARNING!
fuel spray can cause serious injury or
death.
1. Add a substantial amount of fuel to the tank, approximately 2 to 5 gal (8L to
19L).
2. Press ignition switch twice without your foot on brake to put vehicle in Run posi-
tion. This will activate the in tank fuel
pump for approximately 30 seconds. Re-
peat this process twice.
3. Start the engine using the “Normal Start- ing” procedure. Refer to “Starting The
Engine” in “Starting and Operating” for
further information.
CAUTION!
The starter motor will engage for approxi-
mately 30 seconds at a time. Allow two
minutes between cranking 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 un-
der 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 abil-
ity to separate water from the fuel, resulting
in high pressure fuel system corrosion or
damage.
• In addition, commercially available fuel ad- ditives are not necessary for the proper
operation of your diesel engine.
• For extreme cold conditions, "Mopar Pre- mium Diesel Fuel Treatment" is recom-
mended to assist with cold starting.

If the vehicle experiences a sudden loss of
engine power while being driven in heavy
snow or rain, or when plowing snow, and/or
the “SERVICE AIR FILTER” message is dis-
played on the instrument cluster along with a
chime that repeats every 60 seconds, visually
inspect the air filter for snow/ice build up or
extreme water saturation. If the air filter is
not damaged, remove all snow/ice and rein-
stall air filter. If the air filter is damaged,
replace filter element.
NOTE:
The air filter housing contains a Mass Air
Flow sensor. This sensor is critical to proper
engine operation and component longevity.
Any damage or modification to this sensor
could result in major engine and/or exhaust
aftertreatment damage. We recommend you
use Mopar brand parts.
Even though your vehicle is equipped with an
Air Filter Monitor, a visual inspection of the
air cleaner filter element is recommended
every 15,000 miles (24,000km) or
12 months – whichever occurs first.Under nocircumstances should the air cleaner filter ele-
ment exceed 30,000 miles (48,000 km) or
24 months, whichever comes first.
CAUTION!
Many aftermarket performance air filter
elements do not adequately filter the air
entering the engine. Use of such filters can
severely damage your engine.

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.
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.
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 illumi-
nate 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.
CAUTION!
If the “Water In Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain water from the fuel filters to
avoid engine damage.

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 both
fuel filters, the “Water In Fuel Indicator
Light” will remain illuminated for approxi-
mately 10 seconds. If the water was drained
while the engine was running, the “Water In
Fuel Indicator Light” may remain on for ap-
proximately three minutes.
NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately discarded, can present a problem
to the environment. Contact an authorized
dealer, service station, or government agency
for advice on recycling programs and for
