The fuel injection system is controlled through the Powertrain Control
Module (PCM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump
located inside the DFCM and provides pressurized fuel to the engine.
The fuel pump contains a pressure relief valve for overpressure
protection in the event of restricted flow.
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 features are
intended to modify engine performance characteristics.
If these modified engine
performance characteristics persist
for an extended period or either the
service engine soon or powertrain
malfunction/reduced power/
electronic throttle control light is
illuminated, seek service from your authorized dealer.
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. Refer toEngine oilin the
Maintenancechapter.
Fast start glow plug system
The diesel engine glow system consists of:
•eight glow plugs (one per cylinder)
•the glow plug control module (GPCM)
•engine coolant temperature (ECT) sensor
•barometric pressure (BARO) sensor
•environmental temperature sensor
Introduction

2013 Diesel(67l)
Supplement, 1st Printing
USA(fus) 

The glow plug system is
electronically controlled by the PCM
and GPCM. The GPCM energizes the
glow plugs immediately after the ignition is turned on and kept on as
determined by the GPCM using the ECT, BARO and environmental
temperature sensor. The required time for the glow plugs to be
energized decreases as the coolant temperature, barometric pressure and
environmental temperature increase.
Engine and secondary cooling system
The cooling system contains an engine cooling loop to cool the engine
and a secondary cooling loop to cool the transmission, exhaust gas
recirculation (EGR), charge air and fuel. The coolant serves three
primary purposes: to provide heat transfer, freeze point protection, and
corrosion protection using additives.
Vehicles with diesel engines typically are used to carry heavy loads and
accumulate mileage rapidly. These two factors may cause the additives in
the coolant to “wear out” in a shorter time. Refer to theSpecial
operating conditionssection for more information about coolant
additives and coolant change intervals. Operating the engine with
insufficient coolant and/or coolant additive can cause severe engine
damage.
Selective catalytic reduction (SCR) system
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. This system relies on the use of diesel
exhaust fluid (DEF) which must be replenished at certain intervals.
Failure to maintain proper DEF levels or if the DEF becomes
contaminated will result in vehicle speed limitations and/or result in the
vehicle entering an idle-only mode. SeeSelective catalytic reduction
(SCR) systemin theFuel and Refuelingchapter for more information.
Speed control (if equipped)
If vehicle speed goes outside a predetermined range from the set speed,
the RES (Resume) function will not reset vehicle speed. Vehicle speed
will need to be reset with the SET +/- button after reaching desired
speed using accelerator pedal.

Do not crank the engine for more than 10 seconds as starter damage
may occur. If the engine fails to start, turn the key to 3 (off) and wait
30 seconds before trying again.
1. Turn the key to on without
turning the key to start. Do not
start the engine until the
glow-plug pre-heat indicator turns off.
2. When the glow plug pre-heat indicator turns off, turn the key to
start, then release the key as soon as the engine starts. The glow
plugs may remain on for a period of time after engine start. If the
engine is not started before the glow plug activation time ends, the
glow plugs will need to be reset 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.
ENGINE IDLE SHUTDOWN (IF EQUIPPED)
Your vehicle may be equipped with an engine idle shutdown system. This
system automatically shuts down your engine when it has been idling in
P (Park) or N (Neutral) for five minutes (parking brake set) or
15 minutes (parking brake not set). When the engine idle shutdown
process has started:
•A chime sounds and the information display will showENGINE
TURNS OFF IN 30(seconds) and start counting down.
•The 5 or 15 minute timer can be restarted by changing the position
of the accelerator pedal, brake pedal or the park brake within the
final 30 seconds.
•When the timer reaches zero, the engine shuts down and this
message will appear in the information displayENGINE TURNED
OFF.
•One minute after the engine has shut down, the electrical system
simulates key off, even though the ignition is still in the on position,
initiating normal accessory delay period.
•The ignition must be moved to the off position to reset the system
before restarting the vehicle.
The engine idle shutdown idle timer does not start if:
•The engine is operating in power take-off (PTO) mode.
•The engine coolant temperature is below 60°F (16°C).
•The exhaust emission control device (DPF) is regenerating.
Starting and Stopping the Engine

USA(fus) 

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 your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. 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 the foam filter is installed correctly
in place. Remove any debris, snow and/or ice on the foam filter by
brushing the surface with soft brush. Do not use water, solvents, or a
hard brush for cleaning the foam filter.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they are in
optimum condition.
•Use the proper coolant solution at the concentration recommended to
protect the engine against damage from freezing.
•Try to keep the fuel tank full as much as possible at the end of
operation to prevent condensation in the fuel system.
•Make sure you use proper cold weather engine oil and that it is at its
proper level. Also, if necessary, make sure to follow the engine oil and
filter change schedule found under theSpecial operating conditions
section listed in thescheduled maintenance information.
•At temperatures of -10°F (-23°C) or below, it is recommended that
you use an engine block heater to improve cold engine starting.
•If operating in arctic temperatures of -20°F (-29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
The following cold weather idling guidelines are recommended:
•Motorcraft® cetane improvers or non-alcohol-based cetane improvers
from a reputable manufacturer may be used as needed.
•Maintain the engine cooling system properly.
•Avoid shutting the engine down after an extensive idling period. Drive
the vehicle for several miles with the engine at normal operating
temperatures under a moderate load.
•Consider using an engine block heater.
•For extended idle times use an approved idle speed increase device.

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 a ULSD (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 engine coolant system damage, engine overheating,
SCR and/or DPF damage and possible base engine damage.
Use only a diesel engine that has been 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 will
only be made available for sale in countries where ULSD fuel is generally
not available or mandated by the government. Vehicles originally sold in
a ULSD fuel market that are subsequently exported to non-ULSD 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-ULSD fuel.
BIODIESEL
WARNING: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.
This vehicle may be operated on diesel fuels containing up to 20%
biodiesel, also known as B20.
Biodiesel fuel is a product that has been chemically converted from
renewable fuel sources, such as vegetable oils, animal fats and waste
cooking greases.

SCHEDULED MAINTENANCE
The scheduled maintenance services in thescheduled maintenance
informationof this supplement are required because they are
considered essential to the life and performance of your vehicle.
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
Checking the engine oil level
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 least20 minutesafter 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
It is important that only quality engine oils are used in your diesel engine
and it is changed at the recommended service interval. For normal or
severe service, use Motorcraft® oil or an equivalent oil conforming to
Ford specifications or API service categories CJ-4 as listed in the
Capacities and Specificationschapter. It is important to use the

ENGINE AND SECONDARY COOLING SYSTEM COOLANT
Checking the engine coolant
The concentration, additive strength and level of coolant should be
checked at the mileage intervals listed in thescheduled maintenance
information.Be sure to read and understandPrecautions when
servicing your vehiclein yourOwner’s Manual.
When the engine is cold, check the level of coolant in the reservoirs. See
Under Hood Overviewfor the location of the engine and secondary
cooling system reservoirs. If the coolant has not been checked at the
recommended interval, the engine or secondary coolant reservoir may
become low or empty. If either reservoir is low or empty, add coolant to
the reservoir(s). Refer toEngine and secondary cooling system refill
procedurein this chapter.
Note:The engine coolant should be between the MIN and MAX marks
(within the COLD FILL RANGE), as listed on the engine coolant reservoirs.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
If the level is below the MIN mark, add engine coolant immediately see
Adding coolantin this chapter.
Note:For best results, 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.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30 °F and -34 °F.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
