BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles
(1,600 kilometers) of new vehicle operation. Vary your speed to allow
parts to adjust themselves to other parts.
Drive your new vehicle at least 500 miles (800 kilometers) before towing
a trailer. Make sure you use the specified engine oil by checking the
engine oil specification chart underEngine oilin theMaintenance
chapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenancechapter of this supplement for more information on oil
usage.
DIESEL ENGINE INFORMATION
The diesel engine fuel system is a pressurized two-stage filtration system
and consists of:
•a frame-mounted diesel fuel conditioner module (DFCM) / primary
filter with an electric fuel pump and water drain,
•an engine-mounted secondary fuel filter,
•a fuel injector for each cylinder (8 total),
•a high-pressure fuel pump,
•a high-pressure fuel rail for each cylinder bank (2 total) and
•numerous high-pressure pipes from the high-pressure pump to the
rails, and rails to the injectors.
The DFCM acts as a primary fuel filter/water separator which 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 DFCM filter should be changed at the recommended service interval
or when indicated by the information displayLOW FUEL PRESSURE
message. Refer to thescheduled maintenance informationin this
supplement for more information.
The DFCM should be drained at regular intervals (recommended at
every oil change) or when indicated by the information display and water
in fuel indicator light. SeeFuel filter/water separatorin theFuel and
refuelingchapter.
Introduction

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

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

Diesel Exhaust Fluid
With the key in the on position, this
light will illuminate if the exhaust
fluid is contaminated and/or low.
SeeDiesel exhaust fluidin theFuel and Refuelingchapter for more
information.
Glow Plug Pre-Heat
With the key in the on position, this
light will illuminate if glow plug heat
is necessary as a starting aid. Wait
until the light goes off before starting. Refer toCold weather startingin
theStarting and Stopping the Enginechapter of this supplement.
After the engine starts, the light should turn off. The light should always
illuminate at least momentarily when the engine is cold and the ignition
is turned to on.
Water In Fuel
WARNING:Do not drain the DFCM while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.
Note:Air will enter into the fuel system if the DFCM is drained while
the system is running. The engine will not operate properly if air enters
the system.
During refueling, it is possible for
water-contaminated diesel fuel to be
pumped into your tank. Your
vehicle’s fuel system is equipped with a fuel filter/water separator to
remove water from the fuel. The water in fuel light will illuminate when
the DFCM has a significant quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the DFCM. Refer
toFuel filter/water separatorin theFuel and refuelingchapter of this
supplement for the drain procedure. Allowing water to stay in the system
could result in extensive damage to, or failure of, the fuel injection
system.

STARTING THE ENGINE
Read all starting instructions carefully before you start your vehicle.
For temperatures below 32°F (0°C), the use of the correct grade engine
oil is essential for proper operation. Refer toEngine oil specifications
in theMaintenancechapter for more information.
Your vehicle may be equipped with a cold weather starting strategy that
prevents severe engine damage by assisting in engine lubrication
warm-up. In extremely cold ambient temperatures, this strategy activates
and prevents the accelerator pedal from being used for 30 seconds after
starting the vehicle. By not allowing the accelerator pedal to be used, the
engine oil is allowed to properly lubricate the bearings preventing engine
damage due to lack of proper lubrication. After the 30 second warm-up
period, the accelerator pedal will be operational again as long as the
pedal is not being pressed when the 30 second time limit expires. When
starting the engine in extremely cold temperatures (-15°F [–26°C]), it is
recommended to allow the engine to idle for several minutes before
driving the vehicle.
Make sure the gearshift lever is in P (Park) and the parking brake is fully
set before you turn the key. Do not press the accelerator during starting.
Cold Weather Starting
WARNING:Do not use starting fluid, such as ether, in the air
intake system (see air filter decal). Such fluid could cause
immediate explosive damage to the engine and possible personal injury.
WARNING:Do not add gasoline, gasohol or alcohol to diesel
fuel. This practice creates a serious fire hazard and causes
engine performance problems.
It is recommended that the engine block heater be used for starting
when the temperature is -10°F (-23°C) or colder. Refer toEngine block
heater (if equipped)in theStarting and Stopping the Enginechapter
of yourOwner’s Manual.
When operating in cold weather, Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from a reputable manufacturer may
be used as needed.
Starting and Stopping the Engine

USA(fus)

STOPPING THE ENGINE
Turn the ignition to the off position.
To prolong engine life (especially after extended high speed, high
ambient temperature, or high GVW/GCW operation, such as heavy loads
and/or heavy trailers), it is recommended that a hot engine be idled for
3-5 minutes. This allows the turbocharged engine to cool down. For more
information on GVW/GCW, see theLoad Carryingchapter in your
Owner’s Manual.
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 toEngine oil specificationsin theMaintenance
chapter of this supplement.
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/system. Use the proper
anti-gel & performance improver product as listed in theTechnical
Specificationssection in theCapacities and Specificationschapter.
Your vehicle is equipped with a diesel fuel conditioner module (DFCM)
which 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, it is recommended that the fuel level in your
tank should not be allowed to drop below
14full. This helps prevent air
from entering the fuel system and stalling the engine.
Your vehicle is equipped with a an SCR system which uses diesel exhaust
fluid (DEF) to operate properly. DEF must be replenished at certain
intervals. When filling the vehicle’s DEF tank in cold weather, special
care must be taken to prevent damage to the DEF tank. For proper cold
weather fill procedure, seeSelective Catalytic Reduction (SCR) System
in theFuel and Refuelingchapter.

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.

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 section in the
Schedule Maintenancechapter.
•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 frequentLOW FUEL
PRESSUREmessage 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 and / 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 theSpecial operating conditionssection
under theSchedule Maintenancechapter for more information about oil
change intervals and other maintenance when operating on biodiesel.
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 your vehicle will be parked or stored for more than 1 month, then your
vehicle fuel tank should be emptied of biodiesel fuel, filled with a pure
petroleum-based diesel fuel, and run 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
tank if you use a properly formulated diesel fuel. Aftermarket additives
can damage the 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/system. refer to theTechnical
specificationssection in theCapacities and Specificationschapter for
more information.
Repairs to correct the effects of using an aftermarket product that does
not meet Ford specifications in your fuel may not be covered by your
warranty.
Note:Ultra Low Sulfur Diesel fuel is designed to meet the emissions
standards for the 6.7L engine and is backward compatible as well (i.e.,
can be used in Ford 7.3L, 6.9L, 6.4L and 6.0L diesel engines in Ford
vehicles).
FUELING TIPS
WARNING:Do not use starting fluid such as ether or gasoline
in the diesel air intake system. Such fluids can cause immediate
explosive damage to the engine and possible personal injury.
Truck stops have pumps and nozzles designed for larger, heavy-duty
trucks. When refueling at truck stops: if the nozzle shuts off repeatedly
when refueling, wait 5–10 seconds; then use a slower rate of flow (don’t
depress the nozzle trigger as far).
If air is allowed to enter the fuel system (during fuel filter change or if
you run out of fuel) the engine will purge the trapped air as it runs. To
purge the air sooner: prior to engine start, prime the system by turning
the key to on for 30 seconds then to off. Repeat this several times. The
engine may run rough and produce white smoke while air is in the
system. This is normal and should correct itself in a short time.
An engine that suddenly becomes noisy or operates poorly after a fuel fill
could be using substandard fuel (i.e., high water content, low cetane
rating or gasoline in the fuel). Diesel fuel should be purchased from a
reputable station which sells a large amount of diesel fuel.

FUEL FILTER/WATER SEPARATOR
Diesel Fuel Conditioner Module (DFCM)
The vehicle is equipped with a diesel fuel conditioning module (DFCM)
located on the frame-rail under the driver-side floorboard near the
transmission
Water should be drained 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 water level is allowed to exceed this level, the water may be
passed through to the engine and may cause fuel injection equipment
damage.
Draining the DFCM
WARNING:The vehicle must be stopped with the engine off
when draining the DFCM. Fuel may ignite if the separator is
drained while the engine is running or vehicle is moving.
Note:Air will enter into the fuel system if the DFCM is drained while
the system is running. The engine will not operate properly if air enters
the system.
Note:With fuel tank levels above
34tank it may be necessary to loosen
the bowl 3 turns before opening the drain. This will actuate an
anti-siphon valve at the DFCM 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 the drain valve is fully tightened.
1. Stop the vehicle andshut offthe engine.
2. Locate the DFCM and place an appropriate container under the drain
port (see illustration).

3. Rotate the drain counterclockwise
until the O-ring is visible. Allow the
DFCM to drain for approximately
25 seconds or until clean fuel is
observed. Rotate the drain clockwise
to tighten it. If no liquid drains, the
drain may be clogged. Have the
DFCM serviced by your authorized
dealer.
4. Make sure that the drain valve is fully tightened, then remove the
container from under the vehicle.
5. Restart the engine. TheWATER IN FUEL DRAIN FILTERor
WATER IN FUEL DRAIN FILTER SEE MANUALmessage and light
should not be illuminated. If they continues to illuminate, have the fuel
system checked and repaired.
LOW FUEL PRESSURE MESSAGE
The engine is equipped with a low fuel pressure detection system. If the
message center displays:LOW FUEL PRESSUREthe following
explains why and what to do:
•Cold start or cold operation (below 32°F (0°C): If this message
appears during a cold start or during cold operation up to 10 minutes
after the initial cold start, monitor the message center. If it disappears
and does not re-appear after the engine has fully warmed up, the low
fuel pressure message is most likely caused by waxed or gelled fuel.
Do not use alcohol based additives to correct fuel gelling. This may
result in damage to the fuel injectors/systems. Use an anti-gel additive
as listed in theCapacities and Specificationschapter. The 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.
•Low fuel operation: If the message appears when the vehicle is warm
and during low fuel tank level operation, i.e. the tank level is at or
very near empty, refuel the vehicle and operate the vehicle. If the
message reappears after fueling, see below. If the message does not
come back, the low fuel pressure condition was due to low fuel levels
in the fuel tank.
