•
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.

Biodiesel
WARNINGS
Do not use home heating oil,
agricultural fuel, raw fats and oils,
waste cooking greases, biodiesel
fuels greater than 20% or any diesel fuel
not intended for highway use. Damage to
the fuel injection system, engine and
exhaust catalyst can occur if an improper
fuel is used. Do not add gasoline, gasohol
or alcohol to diesel fuel. This practice
creates a serious fire hazard and engine
performance problems. Do not mix diesel fuel with gasoline,
gasohol or alcohol. This could cause
an explosion resulting in personal
injury. Do not add gasoline, gasohol or
alcohol to diesel fuel. This practice
creates a serious fire hazard resulting
in personal injury and engine performance
problems. : Do not use home heating oil or any
diesel fuel not intended for highway
use. Damage to the fuel injection
system, engine, exhaust catalyst and diesel
particulate filter can occur if an improper
fuel is used. Red dye is used to identify
fuels intended for agricultural and
non-highway use. You may operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases. To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
•
Confirm the biodiesel content of the
fuel to be B20 (20% biodiesel) or less
• Only use biodiesel fuel of good quality
that complies with industry standards
• Follow the recommended service
maintenance intervals. See General
Maintenance Information (page 59).
• Do not store biodiesel fuel in the fuel
tank for more than 1 month
• Consider changing brands or reducing
biodiesel content if you have cold
temperature fuel gelling issues or a
frequent LOW FUEL PRESSURE
message appearing
• Do NOT use raw oils, fats or waste
cooking greases
Use of biodiesel in concentrations greater
than 20% may cause damage to your
vehicle, including engine and/or exhaust
after-treatment hardware (exhaust
catalyst and particulate filter) failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that may result
in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil is
recommended for fuels with greater than
5% biodiesel (B5). Refer to the Special
operating conditions section under the
Schedule Maintenance chapter for more
information about oil change intervals and
other maintenance when operating on
biodiesel.

Installation – Engine-mounted fuel
filter
1. Install the new filter into the filter
bracket. Turn the filter clockwise to
lock it in place.
2. Reconnect both fuel lines.
Note: Using a fuel that has more than
average impurities may require you to
replace the fuel filter more frequently than
the service interval specifies.
Note: You will need to purge the system of
air after removal or changing of the filter.
See purging air from the fuel system later
in this chapter.
Purging air from the fuel system
Turn the ignition key to on for 30 seconds,
then turn it to off. Do this six times in a row
to purge any trapped air from the fuel
system.
After filter service, a no start or rough
running engine may indicate that air is
entering the system through the filter bowl
seal or drain. Make sure the drain is tight
and you tightened the filter bowl to the
mechanical stop.
SELECTIVE CATALYTIC
REDUCTION SYSTEM
Your vehicle is equipped with a selective
catalytic reduction system to help reduce
emission levels of oxides of nitrogen from
the exhaust of the diesel engine. The
system automatically injects Diesel
Exhaust Fluid (DEF) into the exhaust
system to enable proper selective catalytic
reduction function. Importance of maintaining the
Diesel Exhaust Fluid (DEF) level
In order for the selective catalytic reduction
system to operate properly, the DEF level
must be maintained. Generally, the DEF
tank should be filled during the oil change
service interval. See General
Maintenance Information (page 59).
However, certain conditions or driving
styles, such as trailer towing or fast rates
of acceleration, will require the refilling of
the DEF tank more often.
The engine control unit will monitor the
amount of fluid available in the DEF tank.
Running a system check in the information
display will indicate whether the DEF level
is ok or if it is less than 1/2 full. A message
will display in the information display when
the DEF level is low and needs to be
refilled. When you see this message, you
should refill your tank. See the Information
displays chapter of your Owner ’s Manual
for information display functions. For
instructions on refilling your DEF tank, see
filling the Diesel Exhaust Fluid (DEF) tank
in this supplement.
Diesel Exhaust Fluid (DEF)
warning messages and vehicle
operations WARNINGS
Diesel Exhaust Fluid (DEF) must be
refilled when low or replaced when
contaminated or your vehicle speed
will be speed limited to 50 mph (80 km/h).
In these conditions, drive with caution and
refill DEF immediately. If the DEF becomes
empty or contaminated and fluid is not
replaced, your vehicle will become limited
to idle speed only once stopped. In these
conditions, be cautious where you stop
your vehicle because you may not be able
to drive long distances and will not be able
to maintain highway speeds until you refill
or replace the DEF.

Scheduled Maintenance
The scheduled maintenance services in
the scheduled maintenance information
of this supplement are required because
they are considered essential to the life
and performance of your vehicle. See
General Maintenance Information
(page 59).
Use only recommended fuel, lubricants,
fluids and service parts conforming to Ford
specifications. Motorcraft® parts are
designed and built for best performance
in your vehicle.
ENGINE OIL CHECK
Because it is normal to add some oil
between oil changes, check your engine oil
level each time you stop for fuel. To check
the engine oil level consistently and
accurately, the following procedure is
recommended:
1. Have engine at normal operating temperature (at least into the NORMAL
range on the engine coolant
temperature gauge).
2. Park the vehicle on a level surface, then
turn off the engine and open the hood.
3. Allow at least 20 minutes after engine
shutdown to ensure that the oil
contained in the upper parts of the
engine has returned to the oil pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it clean and
reinsert fully.
5. Read oil level on both sides of dipstick
and use highest level (reading) for the
actual engine oil level. 6. Maintain the oil level within the
crosshatch area on the dipstick by
adding oil as required. Do not overfill
the oil past the maximum line as
depicted by the arrow.
Engine Oil Specifications
To help achieve acceptable engine
performance and durability, it is important
that only engine oils of good quality are
used in your diesel engine and it is changed
at the recommended interval. For normal
or severe service, use Motorcraft® oil or an
equivalent oil conforming to Ford
specifications as listed in the Capacities
and Specifications chapter. See
Technical Specifications
(page 57). It
is important to use these oils because they
are compatible with the emission control
equipment of your vehicle to meet the
more stringent emission standards.
The use of correct oil viscosities for diesel
engines is important for satisfactory
operation. Determine which oil viscosity
best suits the temperature range you
expect to encounter for the next service
interval from the following SAE viscosity
grade chart.
43
Super Duty (TFA) , enUSA MaintenanceE163369

•
(1) For severe duty service, use SAE
5W-40 API CJ-4.
• (2) For biodiesel fuel blends (B20
max), use SAE 5W-40 or SAE 15W-40
API CJ-4.
An engine block heater is recommended
at temperatures below – 10°F (–23°C). The American Petroleum Institute (API)
service symbol is used to identify the
proper engine oil for your engine. The API
service symbol will be displayeded on the
oil container you purchase. The API symbol
displays the oil performance category in
the top half of symbol and the viscosity
grade in the center of the symbol.
Changing the Engine Oil and Oil
Filter
WARNINGS
Do not handle a hot oil filter with
bare hands.
Continuous contact with used motor
oil has caused cancer in laboratory
mice. Protect your skin by washing
with soap and water. Your vehicle is equipped with an Intelligent
Oil Life Monitor™ that calculates the
proper oil change service interval. When
the information display indicates: OIL
CHANGE REQUIRED, change the engine
oil and oil filter. See the Information
Displays chapter in the Owner's Manual
for more information.
The engine oil filter protects your engine
by filtering harmful, abrasive or sludge
particles and particles significantly smaller
than most available will-fit filters. For
engine oil filter part number, See
Motorcraft Parts (page 55).
To change the engine oil and oil filter:
1. Unscrew the oil filter and oil pan drain plug and wait for the oil to drain.
2. Replace the filter.
3. Reinstall the oil pan drain plug.

ENGINE COOLANT CHECK
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of engine coolant
at the intervals listed in the scheduled
maintenance chapter. See Scheduled
Maintenance (page 59). Note:
Make sure that the level is between
the MIN and MAX marks on the coolant
reservoirs.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See
Adding Engine Coolant
in this chapter.
Note: The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30 °F
(-34 °C) and -34 °F (-37 °C).
Note: For best results, the coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your dealer.
Ford does not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Engine Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, you can
be burned if you spill coolant on hot engine
parts. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.
