MOUNTED AND DIESEL FUEL
CONDITIONER MODULE FUEL
FILTERS - 6.7L DIESEL WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter is inside
the diesel fuel conditioner module. The
module is attached to the fuel tank in
different locations depending on the
configuration of your truck. See table
below for configurations.
Note: The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.
Regular fuel filter changes are an
important part of engine maintenance;
failing to keep with the scheduled
maintenance could lead to engine
performance issues and fuel injection
system damage. See
Scheduled
Maintenance (page 565).
Use only recommended service parts
conforming to specifications. See
Motorcraft Parts
(page 443).
Note: Using fuel that has high levels of
impurities may require more frequent filter
replacements than the service interval
specifies.

3. Drain the diesel fuel conditioner
module. Turn the drain plug
counterclockwise until it stops. Do not
use any tools to loosen the drain plug.
Drain the filter, approximately 0.53 gal
(2 L), into an appropriate container.
Do not re-use the fuel drained from the
module. 4. Disconnect the electrical connector.
5. Fully loosen the bolts securing the
lower portion of the diesel fuel
conditioner module housing.
Note: Do not fully remove the bolts from
the lower portion of the diesel fuel
conditioner module housing.
6. Remove the lower portion of the diesel
fuel conditioner module housing. 7. Slide the filter element toward the
drain plug to disengage the securing
clips.
Installation
1. Slide the filter element into the housing
and fully engage the securing clips.
2. Install the lower portion of the housing.
Tighten the bolts until you feel a strong
resistance. Maximum torque
7 lb.ft
(9 Nm).
3. Connect the electrical connector.
4. Tighten the drain plug, turn it clockwise
until it stops and you feel a strong
resistance. Do not use any tools to
tighten the drain plug.

Engine-mounted Fuel Filter
Although the fuel system is not fully
pressurized when the vehicle is off, some
residual pressure may remain in the fuel
system since it can take some time for the
pressure to completely bleed off.
Therefore, we recommend you place an
absorbent cloth below the filter connectors
to absorb any fuel that may drain.
The engine-mounted fuel filter is a plastic
disposable cartridge.
Removal
1.
Disconnect the fuel lines by squeezing
the connector tabs and pulling the lines
straight off. 2.
Rotate the filter fully counterclockwise
until the peg is at the far end of the slot.
3. Pull the filter straight up from the bracket and discard the filter.
Note: No special air purge is necessary after
filter servicing. The fuel system purges the
air in the filters.
Installation
1. Install the new filter into the filter bracket. Turn the filter clockwise to
lock it in place.
2. Reconnect the fuel lines.
3. Switch the ignition on for 30 seconds and then switch the ignition off.
Repeat this operation six times in a row
to purge any trapped air from the fuel
system.

•
Use a spray with a 40 degree wide
spray angle pattern.
• Keep the nozzle at a 12 in (305 mm)
distance and 90 degree angle to your
vehicle's surface.
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
Underbody
Regularly clean the underside of your
vehicle using water. Keep body and door
drain holes free of debris or foreign
material.
Under Hood
For removing black rubber marks from
under the hood we recommend Motorcraft
Wheel and Tire Cleaner or Motorcraft Bug
and Tar Remover.
WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.
• Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles. •
Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
• Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
Note: If your vehicle has an engine cover
remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.

•
Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE EXHAUST -
6.7L DIESEL WARNING: Failure to maintain the
functional holes, in the tailpipe section
of the exhaust, clean and free of debris
or foreign material may result in the
holes becoming blocked or plugged. Do
not modify or remove the tail-pipe
section. Blocked or plugged holes or
removal/modification of the system
could result in elevated exhaust gas
temperatures which may result in
vehicle/property damage or personal
injury. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter and/or the diesel
particulate filter (DPF). The diesel
oxidation catalytic converter and/or the
DPF heats up to a high temperature after
only a short period of engine operation
and can stay hot even after the engine
is turned off. Failure to follow these
instructions may result in personal injury. The visible holes in the exhaust tip and the
holes under the shield just inboard of the
right rear tire(s) are functional. The holes
need to be kept clear of mud/debris or
foreign material to maintain proper
function of the exhaust system. Clean and
remove debris or foreign material if present
as needed. Spraying with a hose during
regular washing of vehicle should help
keep holes clean and clear of debris or
foreign material.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
