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.

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.

Care should be taken whenever diesel fuel is stored. Use only clean,
approved containers which will prevent the entry of dirt or water.
Diesel fuel must not be stored in a galvanized container. The fuel will
dissolve the zinc in a galvanized container. The zinc will then remain in
the solution until it is run through the engine where it will be deposited
in the fuel injectors causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
This truck is equipped with a fuel fill pipe which is able to accept fuel up
to 20 gallons per minute from a 1
1 8fuel dispensing nozzle. Pumping fuel
at greater flow rates may result in premature nozzle shut-off or spitback.
Fuel filler cap
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
WARNING:If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel tank may damage the
fuel system or cause the fuel cap to disengage in a collision, which may
result in possible personal injury.
Note:If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The vehicle warranty may be void
for any damage to the fuel tank or fuel system if the correct genuine
Ford or Motorcraft® fuel filler cap is not used.
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once.
