or 12 months – whichever occurs first.Under no circum-
stances should the air cleaner filter element 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.

Engine Air Cleaner Filter Installation
NOTE:Inspect and clean the housing if dirt or debris is
present before replacing the air filter element.
1. Install the air cleaner filter element into the housing
assembly with the air cleaner filter inspection surface
facing downward.
2. Install the air cleaner cover onto the housing assembly
locating tabs.
3. Install screws to secure the air cleaner cover to the
housing assembly.
Draining Fuel/Water Separator Filter
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 modelssecond 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 filters when
the engine is running.
•Diesel fuel will damage blacktop paving surfaces.
Drain the filters into an appropriate 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
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.
300 MAINTAINING YOUR VEHICLE

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.
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
your authorized dealer for service.
Upon proper draining of the water from both fuel filters,
the “Water In Fuel Indicator Light” will remain illumi-
nated 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 dis-
carded, can present a problem to the environment. Con-
tact 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) counterclock-
wise 1/4 turn, and turn the under body mounted filter
drain valve (located on the bottom of the filter assembly)
counterclock wise 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 valves by turning them fully
clockwise, and turn the ignition switch to OFF.

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.”
Engine Mounted Fuel Filter Replacement
NOTE:
•Using a fuel filter that does not meet the manufactur-
er’s filtration and water separating 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:
1. No filter is installed.
2. 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 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. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain hose.
3. Open the water drain valve 1/4 turn counterclockwise
and completely drain fuel and water into the ap-
proved container.
4. Close the water drain valve.5. Remove lid using a socket or strap wrench. Rotate
counterclockwise for removal. Remove used o-ring
and discard it.
6. Remove the used filter cartridge from the housing and
dispose of according to your local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Install new o-ring back into ring groove on the filter
housing and lubricate with clean engine oil.
9. Remove new filter cartridge from plastic bag and
install into housing.
NOTE:Do not remove cartridge from bag until you reach
this step in order to keep cartridge clean.
10. Push down on the cartridge to ensure it is properly
seated.Do not pre-fill the filter housing with fuel.
11. Install lid onto housing and tighten to 22.5 ft lbs (30.5
N.m). Do not overtighten the lid.

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. Turn ignition switch to the start position to engage
starter for one second, return ignition switch to run
position. This will activate in tank fuel pump for
approximately 15 seconds. Repeat this process twice.
3. Start the engine using the “Normal Starting” proce-
dure. Refer to “Starting Procedures” in “Starting and
Operating” for further information.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
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 under certain conditions
and be hazardous or explosive when mixed with
diesel fuel.
