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 modelsAir Cleaner Filter

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 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.
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.
282 MAINTAINING YOUR VEHICLE

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. Rotatecounterclockwise 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. 12. Prime the engine using the procedure in “Priming If
The Engine Has Run Out Of Fuel.” Then start the
engine and confirm there are no leaks.
Underbody 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 underbody mounted filter housing will cause the
engine not to run if:
1. No filter is installed.

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.
286 MAINTAINING YOUR VEHICLE

CAUTION!
Do not engage the starter motor for more than 15 sec-
onds 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.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the
use of these fuels can cause damage to the fuel
system.
NOTE:
• A maximum blend of 5% biodiesel, meeting ASTM
specification D-975 may be used with your Cummins
diesel engine. (Chassis Cab models not configured
with B20 capability.)
• A maximum blend of 20% biodiesel, meeting ASTM
specification D-7467 may be used with your Cummins
diesel engine. (Pickup models and Chassis Cab models
configured with B20 capability.)

MAINTAINING YOUR VEHICLE 287

•Use of biodiesel mixture in excess of 20% can nega-
tively impact the fuel filter’s ability to separate water
from the fuel, resulting in high pressure fuel system
corrosion or damage.
• Ethanol blends are not recommended or approved for
use with your Cummins diesel engine.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
mins diesel engine.
Intervention Regeneration Strategy — Message
Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of
the lowest emitting diesel engines ever produced.
To achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust
system. The engine and exhaust after-treatment system work together to achieve the EPA Heavy Duty Diesel
Engine Emissions Standards. These systems are seam-
lessly integrated into your vehicle and managed by the
Cummins Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust sys-
tem’s catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.
Refer to “Electronic Vehicle Information Center (EVIC)”
or “Driver Information Display (DID)” in “Understand-
ing Your Instrument Panel” for further information.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
