DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL
Your vehicle is equipped with a diesel fuel
conditioner module located on the
frame-rail under the driver-side floorboard
near the transmission.
You should drain water from the
module assembly whenever the
warning light comes on and the
message center directs you to drain the
water separator. This will occur when
approximately 8.45 fl oz (250 ml) of water
accumulates in the module. If you allow
the water level to exceed this level, the
water may pass through to the engine and
may cause fuel injection equipment
damage.
Draining the Diesel Fuel
Conditioner Module (DFCM) WARNING
Your vehicle must be stopped with
the engine off when draining the
Diesel Fuel Conditioner Module. Fuel
may ignite if the separator is drained while
the engine is running or vehicle is moving. Note:
If you drain the diesel fuel conditioner
module while the system is running air will
enter into the fuel system. The engine will
not operate properly if air enters the system.
Note: With fuel tank levels above 3⁄4 tank
it may be necessary to loosen the bowl three
turns before opening the drain. This will
actuate an anti-siphon valve at the fuel and
water separator inlet and prevent the fuel
from siphoning out of the tank.
Note: A loose drain valve can allow air to
enter the fuel system and cause drivetrain
issues. The engine will not operate properly.
Be sure that you fully tighten the drain valve. 1. Stop your vehicle and shut off the
engine.
2. Locate the diesel fuel conditioner module and place an appropriate
container under the drain port. 3.
Rotate the drain counterclockwise until
the O-ring is visible. Allow the diesel
fuel conditioner module to drain for
approximately 25 seconds or until
clean fuel is observed. Rotate the drain
clockwise to tighten it. If no liquid
drains, there may be a clog in the drain.
Have the conditioner module serviced
by an authorized dealer.
4. Make sure that you fully tighten the drain valve and then remove the
container from under your vehicle.
5. Restart the engine. If the WATER IN FUEL DRAIN FILTER or WATER IN FUEL
DRAIN FILTER SEE MANUAL message
and light continues to illuminate, have
the fuel system checked and repaired.
FUEL FILTER - 6.8L
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.

CHANGING THE ENGINE AIR
FILTER - 6.8L
WARNING
To reduce the risk of vehicle damage
and personal burn injuries, do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running. Note:
Operating your vehicle in heavy
snowfall or extreme rain conditions may
allow excessive amounts of snow or water
into the air intake system. This could plug
or soak the air filter that could cause the
engine to lose power or shut down.
When replacing the air filter element, use
a Motorcraft® air filter element. See
Motorcraft Parts (page 254).
Note: Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage
may not be covered by the vehicle Warranty.
Change the air filter element at the correct
interval. See
Scheduled Maintenance
(page 316). 1. Locate the mass air flow sensor
electrical connector on the air outlet
tube. Disconnect the mass air flow
sensor electrical connector. 2. Reposition the locking clip on the
connector (connector shown from
below for clarity), squeeze the
connector and pull it off of the air
outlet tube. 3.
Clean the area from around the air tube
to the air cover connection to prevent
debris from entering the system. Next,
loosen the bolt on the air tube clamp
so the clamp is no longer snug to the
air tube. It is not necessary to
completely remove the clamp.
4. Pull the air tube off from the air cleaner
housing.

Air Filter Restriction Gauge WARNING
To reduce the risk of vehicle damage
and/or personal burn injuries do not
start your engine with the air filter
removed and do not remove it while the
engine is running. Note:
Operating your vehicle in heavy
snowfall or extreme rain conditions may
allow excessive amounts of snow or water
into the air intake system. This could plug
or soak the air filter that could cause the
engine to lose power or shut down.

The restriction gauge, located on the upper
housing of the air filter assembly, measures
the vacuum inside the air filter. The more
the air filter is restricted (dirty, clogged),
the higher the vacuum reading.
Check the air filter restriction gauge
whenever you open the hood to perform
general engine maintenance or at least
every 7,500 miles (12,000 km). If you
operate your vehicle in extremely dusty
conditions, check and reset the gauge at
least every 500 miles (800 km), or two
weeks, whichever comes first. Change the
air filter when the restriction gauge reads
near the change filter line and the gauge
is yellow. If you allow the restriction gauge
to reach maximum restriction you can
affect your engine performance and fuel
economy.
Note:
Do not blow out the air filter element
with compressed air since the compressed
air could damage the filter paper.
Note: Do not rely on filter appearance
alone. A filter which appears to be dirty may
actually have several thousand miles
(kilometers) of life remaining. After installation of the new filter element,
reset the gauge by pressing the reset
button on top of the gauge.
The following actions are recommend after
operating the vehicle up to 200 miles (320
km) in heavy snowfall or extreme rain:
•
Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do NOT
remove the foam filter) and reset the
air filter restriction gauge.
• Extreme rain: The air filter will dry after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Air Filter Replacement
When replacing the air filter element, use
a Motorcraft® air filter element. See
Motorcraft Parts (page 255).
Note: Failure to use the correct air filter
element may result in severe engine
damage.

2. Remove the clips that secure the air
filter housing cover. Push the air filter
cover forward (away from you) and up
slightly to release it.
3. Remove the air filter element from the
air filter housing. 4. Remove and install a new foam filter
if needed according to the service
interval indicated in the scheduled
maintenance information in this guide.
If you do not replace the foam filter, be
sure the existing foam filter is in place. 5. Install a new air filter element. Be sure
that the groove seal on the pleated
paper filter traps both sides of the
vertical partition of the air box.
6. Engage the clips to secure the air filter housing cover to the air filter housing.
Be careful not to crimp the filter
element edges between the air filter
housing and cover. Ensure that you
align the tabs on the edge properly into
the slots.
7. Reconnect the mass airflow sensor electrical connector to the inlet tube.
Make sure the locking tab on the
connector is in the locked position.

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.
5. 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. 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.
