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: Do not drain the
water-in-fuel separator while the engine
is running. Failure to follow this warning
may result in fire, serious injury, death or
property damage.
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 message and light
continues to illuminate, have the fuel
system checked and repaired.
ENGINE COOLANT CHECK -
6.7L DIESEL
WARNING: Do not remove the
coolant reservoir cap when the cooling
system is hot. Wait 10 minutes for the
cooling system to cool down. Cover the
coolant reservoir cap with a thick cloth
to prevent the possibility of scalding and
slowly remove the cap. Failure to follow
this instruction could result in personal
injury.
WARNING: Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield.
WARNING: To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly.
WARNING: Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 319).
Note:Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant
WARNING: Do not add engine
coolant when the engine is hot. Failure
to follow this instruction could result in
personal injury.
WARNING: Do not remove the
coolant reservoir cap when the cooling
system is hot. Wait 10 minutes for the
cooling system to cool down. Cover the
coolant reservoir cap with a thick cloth
to prevent the possibility of scalding and
slowly remove the cap. Failure to follow
this instruction could result in personal
injury.
Note: Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.

Maintenance

WASHER FLUID CHECK
WARNING: If you operate your
vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See Capacities and
Specifications (page 288).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle’s paint finish, wiper blades or
washer 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

EXHAUST SYSTEM
INSPECTION
Note:If your vehicle is equipped with a
catalytic converter or muffler, do not blend
waste oil with diesel fuel. Operate only on
ultra-low sulfur (less than 15 parts per
million sulfur) diesel fuel with a cetane
value of 45 or higher.
If your diesel engine is equipped with a
catalytic converter, it is important to review
the maintenance schedule to make sure
proper functioning of the catalytic
converter. Also, take precautions not to
damage the catalytic converter when
servicing your engine or storing your
vehicle.
BRAKE SYSTEM INSPECTION
WARNING: Always wear a
respirator approved by the National
Institute of Occupational Studies of
Health (NIOSH) or Mine Safety and
Appliance (MSA) during all brake service
procedures. Wear the respirator from
removal of the wheels through assembly.
Never use compressed air or dry brushing
to clean brake parts or assemblies.
Clean brake parts and assemblies in
open air. During assembly, carefully
place all parts on the floor to avoid
getting dust in the air. Use an industrial
vacuum cleaner with a HEPA filter
system to clean dust from the brake
drums, backing plates and other brake
parts. After using the vacuum, remove
any remaining dust with a rag soaked in
water and wrung until nearly dry.
Never use compressed air or dry
sweeping to clean the work area. Use an
industrial vacuum cleaner with a HEPA
filter system and rags soaked in water
and wrung until nearly dry. Dispose of
used rags with care to avoid getting dust
in the air. Use an approved respirator
when emptying vacuum cleaners and
handling used rags.
Worker clean-up: Wash your hands
before eating, drinking or smoking.
Vacuum your work clothes after use and
then launder them separately, without
shaking them, to prevent fiber dust
getting into the air.
Your vehicle is equipped with
non-asbestos brake linings. However,
exposure to excessive amounts of brake
material (whether asbestos or
non-asbestos, fiberglass, mineral wool,
aramid or carbon) may be a serious health
hazard.
255
Maintenance

• 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 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.
To clean the windshield and wiper blades:
• Clean the windshield with a
non-abrasive glass cleaner. When
cleaning the interior of the windshield,
avoid getting any glass cleaner on the
instrument panel or door panels. Wipe
any glass cleaner off these surfaces
immediately.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
Note: Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.
CLEANING THE INTERIOR
WARNING: Do not use cleaning
solvents, bleach or dye on the vehicle's
seatbelts, as these actions may weaken
the belt webbing.
WARNING: On vehicles equipped
with seat-mounted airbags, do not use
chemical solvents or strong detergents.
Such products could contaminate the
side airbag system and affect
performance of the side airbag in a crash.
For fabric, carpets, cloth seats and seats
equipped with side airbags:
• Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner.
• If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.
• Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials.
