POWER STROKE DIESEL ENGINE
Your new diesel engine will feel, drive and function somewhat differently
than a gasoline engine. Therefore it is very important that you read and
thoroughly familiarize yourself and others operating the vehicle with this
guide.A special procedure for turning off the diesel engine is in the
Drivingchapter. It is important to read and understand this
material in order to maintain the best service life for your engine.
This guide will acquaint you with the Power Stroke diesel engine. It
provides recommendations on engine care and operating procedures. For
complete vehicle information, also refer to theOwner’s Guideincluded
with the vehicle. It also describes equipment and gives specifications for
equipment that was in effect when this guide was approved for printing,
and should be considered a permanent part of the vehicle.
Some aftermarket products may cause severe engine/transmission
and/or exhaust system damage;refer to theWarranty Guidefor
more information.Your vehicle’s powertrain control systems can
detect and store information about vehicle modifications that
increase horsepower and torque output such as whether or not
performance-enhancing powertrain components commonly
referred to as “performance chips” have been used. This
information cannot be erased and will stay in the system’s
memory even if the modification is removed. The information can
be retrieved by Ford Motor Company, Ford of Canada, Ford of
Mexico and service and repair facilities when servicing your
vehicle. This information may be used to determine if repairs will
be covered by warranty.
Ford may discontinue models or change specifications without any notice
and without incurring obligations.
Important notice
Ford vehicles are suitable for producing ambulances only if equipped
with the Ford ambulance preparation package. In addition, Ford urges
ambulance manufacturers to follow the recommendation of theFord
Incomplete Vehicle Manual, Ford Truck Body Builder’s Layout Book
(and pertinent supplements) and theQualified Vehicle Modifiers
Guidelines.Using a Ford vehicle without the Ford ambulance
preparation package to produce an ambulance voids the Ford warranty
and could result in elevated underbody temperatures, fuel
overpressurization and the risk of fuel expulsion and fires. To determine
whether the vehicle is equipped with the Ford ambulance preparation

the DFCM filter should be changed at the recommended service interval
or when indicated by the message centerLOW FUEL PRESSURE
message. Refer to thescheduled maintenance informationin this
supplement for more information.
The DFCM should be drained at regular intervals or when indicated by
the message center message and water in fuel indicator light. SeeFuel
filter/water separatorin theMaintenance and Specificationschapter.
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 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
Maintenance and Specificationschapter.
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

Operation in standing water
Ingestion of water into the diesel engine can result in immediate and
severe damage to the engine. If driving through water, slow down to
avoid splashing water into the intake. If the engine stalls, and ingestion
of water into the engine is suspected, do not try to restart the engine.
Consult your dealer for service immediately.
Rapid heat supplemental heating system (if equipped)
The optional rapid heat feature is an electrically powered device that is
designed to provide supplemental heat during engine warm up. For
maximum effectiveness mid to low blower speed is recommended during
initial warm up. When operating in automatic mode (when equipped) the
climate control unit will determine the appropriate blower speed for
existing conditions.
Note:Additional aftermarket electrical loads operated during engine
warm up may impact the performance of the rapid heat supplemental
heater.
DUAL FUEL TANK SELECTOR CONTROL (IF EQUIPPED)
If your vehicle is equipped with dual
fuel tanks, you will have a selector
control, located to the right of the
steering wheel, which allows you to
draw fuel from either tank. Your fuel
gauge and the DTE (distance to
empty) will display the amount of
fuel in the currently selected tank.
INTEGRATED ENGINE BRAKING
This feature increases engine braking at higher engine speeds to provide
better grade descent control with less brake and transmission wear and
tear.
This feature is integrated with the tow/haul mode feature. When tow/haul
mode is switched on, the integrated engine braking feature will also be
active. For more information on tow/haul, seeAutomatic transmission
operationin theOwner Guide.

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. Motorcraftparts are designed and
built for best performance in your vehicle.
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)
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel (also known as ULSD) in your 6.7L diesel
engine.The engine and exhaust system were designed to only use this
fuel. Look for theULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
(15 ppm Sulfur Maximum)label on fuel pumps when purchasing your
fuel.
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 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. See
Cold weather operationin theDrivingchapter of this supplement.
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.
Maintenance and Specifications

2012 Diesel(67l)
Supplement(supplement), 1st Printing
Arabic_(LHD)(gc_lhd)

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. Engine damage from using the improper type of fuel
is not covered under your warranty.
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.
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 temperature.
SeeCold weather operationin theDrivingchapter of this supplement.
BIODIESEL
This vehicle may be operated on diesel fuels containing up to 20%
biodiesel, also known as B20.
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.
5W-40 or 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.
Biodiesel fuel is a product that has been converted from renewable fuel
sources, including vegetable oil, animal fat and cooking oil. Raw or
refined vegetable oil, animal fat, cooking oil or recycled greases should
NOTbe used.
WARNING:Do not use home heating oil, agricultural fuel 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.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets either the
ASTM D975 diesel or the ASTM D7467 B6-B20 biodiesel industry
Maintenance and Specifications

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.
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. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of maintaining the DEF level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled during the oil
change service interval. See thescheduled maintenance informationin
this supplement for more information. 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 message center will indicate
whether the DEF level is ok or if it is less than 1/2 full. A message will
automatically be displayed in the message center when the DEF level is
low and needs to be refilled. When you see this message you should refill
your tank. SeeMessage centerin theInstrument Clusterchapter of
yourOwner’s Guidefor message center functions. For instructions on
refilling your DEF tank, seeFilling the DEF tanklater in this section.
DEF warning messages and vehicle operations
WARNING:Diesel Exhaust Fluid (DEF) must be refilled when
low or replaced when contaminated or the 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 fluid is not replaced, the vehicle will become limited to
idle speed only once stopped. In these conditions, be cautious where
you stop the vehicle because you may not be able to drive long
distances and will not be able to maintain highway speeds until DEF is
refilled or replaced.
Maintenance and Specifications

2012 Diesel(67l)
Supplement(supplement), 1st Printing
Arabic_(LHD)(gc_lhd)

To prevent overfilling of the DEF tank when filling with a bottle, Ford
recommends using MotorcraftDEF. Additionally, if the message center
indicatesEXHAUST 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 message center indicatesEXHAUST
FLUID LEVEL OK, do not add DEF.
Contaminated DEF or inoperative SCR system
SCR systems are sensitive to
contamination of the DEF. USE
ONLY API or ISO 22241 CERTIFIED
DIESEL EXHAUST FLUID. If the
SCR becomes contaminated or
inoperative, the DEF light will
illuminate and exhaust fluid system
fault messages will appear in the
message center.
Continued driving without replacing DEF or having the SCR system
repaired will result in the following actions as required by the California
Air Resources Board (CARB) and /or 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 message center.
•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 message center indicating required actions to resume normal
operation.
For either vehicle speed limiting or idle-only condition, normal vehicle
operation will resume when the contaminated system is repaired.To
service a contaminated or inoperative system, see your
authorized dealer.
DEF guidelines and information
•Use only DEF 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 or nozzle once it is emptied.
