A high-pressure fuel rail for each
cylinder bank (2 total)
• Numerous high-pressure pipes from
the high-pressure pump to the rails,
and rails to the injectors
The fuel and water separator removes
both water and impurities from the fuel.
The engine mounted filter filters finer
impurities from the diesel fuel. The
engine-mounted fuel filter and the fuel and
water separator filter should be changed
at the recommended service interval or
when indicated by the information display
LOW FUEL PRESSURE message. Refer to
the scheduled maintenance information
in this supplement for more information.
The fuel and water separator should be
drained at regular intervals (recommended
at every oil change) or when indicated by
the information display and water in fuel
indicator light. See Fuel Quality (page
15).
Proper fuel filter maintenance and prompt
water draining when the water in fuel light
illuminates is essential to prevent injection
equipment damage. Ignoring the water in
fuel light can cause your vehicle to go into
a reduced power mode.
A frame-mounted electric fuel pump
located inside the fuel and water separator
draws fuel from the fuel tank to provide
pressurized fuel to the engine. The fuel
pump contains a pressure relief valve for
overpressure protection in the event of
restricted flow.
The fuel injection system is controlled
through the powertrain control module. Engine protection mode
Ford diesel engines are equipped with
engine protection and emission control
systems. These systems monitor critical
temperatures and pressures, and modify
engine operation accordingly. These
modified engine performance
characteristics are normal.
If these modified engine performance
characteristics persist for an extended
period and either the service engine soon
or powertrain malfunction,reduced power,
electronic throttle control light is
illuminated, have the system checked by
an authorized dealer.
Service engine soon
Powertrain malfunction, reduced
power, electronic throttle control
Lubrication system
It is important to change the engine oil at
the recommended service intervals to
maintain oil viscosity. Extending the oil and
filter change interval beyond the
recommended interval can negatively
affect engine performance, fuel economy
and engine life. See
Engine Oil Check
(page 43).
Fast start glow plug system
The diesel engine glow system consists of:
• Eight glow plugs (one per cylinder)
• Glow Plug Control Module
• Engine Coolant Temperature sensor
• Barometric pressure sensor
• Environmental temperature sensor

Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to START the lights become dim or
go out, the battery connections may be
loose or corroded, or the battery may be
discharged. If there is a clicking or
stuttering sound coming from the engine
compartment when you turn the key to
START, this may also indicate a loose or
corroded battery connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.
•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, refer
to Jump Starting in the Roadside
Emergencies chapter of your Owner ’s
Manual.
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump. •
Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive
• Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter

WARNING LAMPS AND
INDICATORS
The following warning lamps and
indicators will alert you to a vehicle
condition that may become serious. Some
lamps will light when you start your vehicle
to make sure they work. If any lamps
remain on after starting your vehicle, refer
to the respective system warning lamp for
further information. Note:
Some warning indicators appear in
the information display and function the
same as a warning lamp but do not display
when you start your vehicle.

Diesel Exhaust Fluid (DEF) (If
Equipped) With the key in the on position,
lights when the DEF is
contaminated or low. See
Selective Catalytic Reduction System
(page
21).
Glow Plug Pre-Heat With the key in the on position,
lights when the glow plug heat
is necessary as a starting aid.
Wait until the light goes off before starting.
See
Starting a Diesel Engine (page 10).
After you start the engine, the light should
turn off. When the engine is cold, the light
should always light for a short period.
Water In Fuel During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator lights when
the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel lights when the engine
is running, stop your vehicle as soon as
safely possible, shut off the engine, then
drain the fuel and water separator. See
Fuel Quality
(page 15). Allowing water
to stay in the fuel system, after the water
in fuel indicator lights, could result in
extensive damage or failure of the fuel
injection system. WARNING
Do not drain the fuel and water
separator while the engine is running.
Fuel may ignite if the separator is
drained while the engine is running or the
vehicle is moving. Note:
Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.

When the glow plug pre-heat indicator
turns off, turn the key to start and
release the key as soon as the engine
starts. After starting the engine, the
glow plugs may remain on for a period.
If you do not start the engine before
the glow plug activation time ends, you
will need to reset the glow plugs by
turning the key to off.
3. After the engine starts, allow it to idle for about 15 seconds. This is to protect
the engine. Do not increase engine
speed until the oil pressure gauge
indicates normal pressure.
Cold Weather Operation
Note: Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Changing to a lighter grade engine oil also
makes starting easier under these
conditions. Refer to Engine oil
specifications. See Technical
Specifications (page 57).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
alcohol based additives to correct fuel
gelling. This may result in damage to the
fuel injectors and system. Use the proper
anti-gel and performance improvement
product. See
Technical Specifications
(page 57). Your vehicle is equipped with a fuel and
water separator that recirculates fuel from
the engine to help prevent fuel filter
clogging. To avoid engine fuel starvation
during cold weather operation of 32°F
(0°C) or below, we recommended that
the fuel level in your tank should not drop
below 1⁄4 full. This helps prevent air from
entering the fuel system and stalling the
engine.
Your vehicle is equipped with a selective
catalyst reduction system that uses Diesel
Exhaust Fluid (DEF) to operate properly.
You need to replenish your vehicle
’s DEF
at certain intervals. When filling your
vehicle ’s DEF tank in cold weather, you
must take special care to prevent damage
to the tank. See
Selective Catalytic
Reduction System (page 21).
In cold weather below 32°F (0°C), the
engine may slowly increase to a higher idle
speed if left idling in P (Park). As the engine
warms-up, the engine sound level
decreases due to the activation of
PCM-controlled sound reduction features.
If you operate your vehicle in a heavy
snowstorm or blowing snow conditions,
snow and ice can clog the engine air
induction. If this occurs, the engine may
experience a significant reduction in power
output. At the earliest opportunity, clear
all the snow and/or ice away from inside
the air filter assembly. Remove the air
cleaner cover and the pleated paper filter,
leaving the foam filter in and remove any
snow or ice. Make sure you install the foam
filter correctly in place. Remove any debris,
snow or ice on the foam filter by brushing
the surface with soft brush. Once you have
cleared all of the debris, reinstall the air
filter and assembly.
Do not use water, solvents, or a hard brush
for cleaning the foam filter.

FUEL QUALITY
Fuel Requirements - Choosing The
Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Required (United
States/Canada/Puerto Rico/U.S.
Virgin Islands And Other Locales)
Note:
Your warranty will not cover damage
caused by using an improper type of fuel or
fuel additive.
Note: Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel will
significantly increase your vehicle ’s exhaust
emissions and reduce engine life due to
increased internal wear.
You should use Ultra-Low Sulfur Diesel
fuel (also known as ULSD) designated as
number 1-D or 2-D with a maximum of
15-ppm sulfur in your diesel vehicle. You
may operate your vehicle on diesel fuels
containing up to 20% biodiesel, also
known as B20. These fuels should meet
the ASTM D975 diesel or the ASTM D7467
B6-B20 biodiesel industry specifications.
Outside of North America, use fuels
meeting EN590 or equivalent local market
standard. Using low sulfur diesel fuel
(16-500 ppm) or high sulfur
diesel fuel (greater than 500
ppm) in your diesel engine will cause
certain emission components to
malfunction which may also cause the
service engine soon light to illuminate
indicating an emissions-related concern.
Diesel fuel is adjusted seasonally for cold
temperature. For best results at
temperatures below 20°F (-7°C), it is
recommended to use a diesel fuel which
has been seasonally adjusted for the
ambient conditions. Fuel Requirements - Choosing The
Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Not Required
For the engine to operate reliably on
low-sulfur or high-sulfur diesel fuel, the
engine must be a factory built high-sulfur
engine (available as a dealer order option
for select markets) or an ultra low sulfur
diesel fuel configured engine that has been
retrofitted for high-sulfur diesel fuel using
Ford Motor Company dealer service parts.
Failure to use retrofit components other
than those available through your
authorized dealer will result in coolant
system damage, engine overheating,
selective catalyst reduction system or
diesel particulate filter damage and
possible base engine damage.
Use only a diesel engine configured for use
with high sulfur diesel fuel in markets with
diesel fuel that has sulfur content greater
than 15 ppm. Using low sulfur diesel fuel
(16–500 ppm) or high sulfur diesel fuel
(greater than 500 ppm) in a diesel engine
designed to use only Ultra Low Sulfur
Diesel fuel may result in damage to engine
emission control devices and the
aftertreatment system, potentially
rendering the vehicle inoperable.
Vehicles with engines configured for use
with high sulfur diesel fuel are only
available for sale in countries where ultra
low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in a ultra low sulfur
diesel fuel market that are subsequently
exported to non- ultra low sulfur diesel fuel
markets will need to be retrofitted (at the
customer
’s expense using Ford authorized
dealer service parts) in order to be reliably
operated on non- ultra low sulfur diesel
fuel.

Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in a diesel fuel. Biodiesel content is often
indicated with the letter B followed by the
percent of biodiesel in the fuel. For
example, B20 indicates a fuel containing
20% biodiesel. Ask the service station
attendant to confirm the biodiesel content
of a diesel fuel if you do not see a label on
the fuel pump.
Biodiesel fuels degrade more easily than
diesel fuels not containing biodiesel and
should not be stored in the fuel tank for
more than 1 month. If you plan to park or
store your vehicle for more than 1 month,
then you should empty your vehicle fuel
tank of biodiesel fuel. You should fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle for a minimum of
30 minutes.
Note:
Degraded or oxidized biodiesel can
damage fuel system seals and plastics and
corrode steel parts.
During cold weather, if you have problems
operating on biodiesel, you may need to
use a diesel fuel with lower biodiesel
content, try another brand, or discontinue
the use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add any
aftermarket additives to your fuel if you
use a high quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
injector system or engine.
Use Motorcraft® cetane booster or an
equivalent cetane booster additive if you
suspect fuel has low cetane. Use
Motorcraft® anti-gel & performance
improver or an equivalent additive if there
is fuel gelling. Do not use alcohol-based additives to
improve cetane quality, to prevent fuel
gelling or any other use. The use of alcohol
additives may result in damage to the fuel
injectors and system. See Technical
Specifications (page 57).
Your warranty may not cover repairs
needed to correct the effects of using an
aftermarket product that does not meet
Ford specifications in your fuel.
Note: Ultra Low Sulfur Diesel fuel is
designed to meet the emissions standards
for the 6.7L engine and is backward
compatible as well (for example, it can be
used in the 7.3L, 6.9L, 6.4L and 6.0L diesel
engines in Ford vehicles.
Fuel And Water Separator
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 0.32 pints (150 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. 17
Super Duty (TFA) , enUSA Fuel and Refueling
Page 21 of 84
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 3
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.
Low Fuel Pressure
The engine is equipped with a low fuel
pressure detection system. Here are some
possible causes if a low fuel pressure
message appears in the information
display:
• Cold start or during cold operation
(below 32°F (0°C): If the low fuel
pressure message appears during a
cold start or up to 10 minutes after the
initial cold start, monitor the
information display. If the low fuel
pressure message disappears and does
not re-appear after the engine has fully
warmed up, waxed or gelled fuel is
what most likely caused the message.
Do not use alcohol based additives to
correct fuel gelling. This may result in
damage to the fuel injectors and
systems. Use an anti-gel additive. See
Technical Specifications (page 57).
Note: Your customer warranty may be void
from using additives that do not meet or
exceed Ford specifications. If the low fuel
pressure message persistently appears after
re-fueling during the cold start and cold
operation conditions defined previously and
then disappear when the engine has fully
warmed up, consider different fuel sources.

5.
When the DEF tank is full, the fluid level
in the bottle will stop dropping,
indicating the fluid has stopped
flowing. 6. Once the level in the DEF bottle has
stopped dropping, return the container
to the vertical position slightly below
the DEF filler port and let any DEF drain
out of the spout. DO NOT try to
continue to add DEF to the tank by
shaking or repositioning the container
to induce flow. This may cause spilling
and overfill the tank. Overfilling the DEF
tank can cause damage to the tank.
7. Once the spout has drained, remove the spout from the DEF filler port and
install the blue cap on the DEF filler
port.
8. Remove the spout from the diesel exhaust fluid container and install the
cap back on the bottle.
9. If the container is empty, discard the empty container, or recycle if possible.
If there is DEF left in the container,
retain it for later use. The spout is
re-useable; after use, rinse it with clean
water and store the spout to keep it
clean. Do not use the DEF spout with
any other chemicals.
10. Wipe away any DEF that has spilled on painted surfaces with water and
a damp cloth. Diesel Exhaust Fluid (DEF) filling station
nozzle fill
Filling the Diesel Exhaust Fluid (DEF) tank
using a nozzle is similar to a normal fuel
fill. The nozzle will shut off automatically
when the tank is full. Do not continue to fill
the tank as this may cause spilling and
overfill can cause damage to the tank.
Note:
Some filling station nozzles may
prevent filling of your DEF tank due to a
magnetic mechanism in the nozzle. This is
not a problem with your vehicle. To refill
your tank either locate another filling station
or use a bottle to refill the tank.
Filling the Diesel Exhaust Fluid (DEF)
tank in cold climates
Diesel Exhaust Fluid (DEF) will freeze
below 12°F (-11°C); however, your vehicle
is equipped with an automatic preheating
system which allows the DEF system to
operate below 12°F (-11°C). When your
vehicle is not in operation for an extended
period with temperatures at or below 12°F
(-11°C), the DEF tank could freeze. If the
tank is OVERFILLED and freezes, it could
be damaged, therefore DO NOT OVERFILL.
To prevent overfilling of the DEF tank when
filling with a bottle, Ford recommends
using Motorcraft® Diesel Exhaust Fluid
(DEF). Additionally, if the information
display indicates EXHAUST FLUID UNDER
1/2 FULL, you should only add a MAXIMUM
of 2 gallons (6.7L) of DEF to the tank to
prevent freeze damage due to overfilling.
If the information display indicates
EXHAUST FLUID LEVEL OK, do not add
DEF.

Contaminated Diesel Exhaust Fluid
(DEF) or inoperative Selective
Catalytic Reduction system
Selective catalytic reduction
systems are sensitive to
contamination of the Diesel
Exhaust Fluid (DEF). USE ONLY API or ISO
22241 CERTIFIED DIESEL EXHAUST FLUID
(DEF). If the selective catalytic reduction
system becomes contaminated or
inoperative, the Diesel Exhaust Fluid (DEF)
light will illuminate and exhaust fluid
system fault messages will appear in the
information display.
Continued driving without replacing DEF
or having the selective catalytic reduction
system repaired will result in the following
actions as required by the California Air
Resources Board (CARB) and U.S.
Environmental Protection Agency (EPA):
• Within a certain number of miles
(kilometers) to empty, speed will be
limited upon restart. Prior to this
occurring a message will appear in the
information display.
• Further vehicle operation without
replacing contaminated DEF will cause
the engine to enter an idle-only
condition. This will only occur upon
vehicle refueling, vehicle idling in park
for 1 hour, or engine shutdown for 10
minutes or more and will be indicated
by a message in the information display
indicating required actions to resume
normal operation.
For either vehicle speed limiting or idle-only
condition, normal vehicle operation will
resume when you repair the contaminated
system. To service a contaminated or
inoperative system, see an authorized
dealer. Diesel Exhaust Fluid (DEF) guidelines
and information
•
Use only Diesel Exhaust Fluid that
carries the trademark: American
Petroleum Institute (API) certified DEF
or ISO 22241.
• Do not put DEF in the diesel fuel tank.
• Do not overfill the DEF tank.
• Do not re-use the DEF container once
it is emptied.
• Avoid spilling DEF on painted surfaces,
carpeting or plastic components.
Immediately wipe away any DEF that
has spilled with a damp cloth and
water. If it has already crystallized, use
warm water and a sponge.
• Store DEF out of direct sunlight and in
temperatures between 23°F (-5°C) —
68°F (20°C).
• DEF will freeze below 12°F (-11°C).
• Do not store the DEF bottle in your
vehicle. If it leaks it could cause
damage to interior components or
release an ammonia odor inside your
vehicle.
• DEF is non-flammable, non-toxic,
colorless and water-soluble liquid.
• Do not dilute DEF with water or any
other liquid.
• An ammonia odor may be smelled
when the cap is removed or during
refill. Refill DEF in a well ventilated
area.
