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
Introduction

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

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 theMaintenance and Specificationschapter 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.

If the vehicle’s speed is limited or the vehicle has entered an
idle-only mode
If the vehicle’s speed is limited or in an idle-only mode, the SCR system
may be limiting the vehicle’s functions due to low or contaminated diesel
exhaust fluid (DEF). Check the DEF. SeeSelective catalytic reduction
(SCR) systemin theMaintenance and Specificationschapter for more
information.
Cold weather starting
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 theDrivingchapter of theOwner’s Guide.
When operating in cold weather, use Motorcraftcetane improvers or
non alcohol-based cetane improvers from a reputable manufacturer.
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.
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.
1. Turn the key to on without turning the key to start.Do not start the
engineuntil 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 will automatically shut 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 will sound and the message center will displayENGINE
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 the message
center will displayENGINE TURNED OFF.
•One minute after the engine has shut down, the electrical system will
simulate 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.
Note:The engine idle shutdown idle timer will 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.
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 which will allow the turbocharged engine to cool down. For
more information on GVW/GCW, seeVehicle loading – with and
without a trailerin theOwner guide

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.
Note:Idling in cold weather will 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.
The following cold weather idling guidelines are recommended:
•Use Motorcraftcetane improvers or non alcohol-based cetane
improvers from a reputable manufacturer.
•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.

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.

OCR precautions and safe exhaust position
WARNING:Failure to comply with the following instructions for
operator commanded regeneration (OCR) may result in fire,
serious injury, death and/or property damage.
Before you start OCR, observe/do the following:
•Place the vehicle in P (Park) with the parking brake set on stable,
level ground.
•The vehicle must not be parked in a structure.
•The vehicle must be 10 – 15 feet (3 – 5 meters) away from any
obstructions,
•and must be away from materials that can easily combust or melt such
as: paper, leaves, petroleum products, fuels, plastics and other dry
organic material, such as grass.
•Make sure there is a minimum of 1/8 tank of fuel.
•Make sure all fluids are at proper levels.
Make sure that the louvers (holes) located at the tip of the exhaust are
also clear of any obstructions as they are used to introduce fresh air into
the tailpipe to cool the exhaust gas as it leaves. SeeExhaustunder the
Cleaningchapter for more information.
How to start operator commanded regeneration (OCR)
WARNING:Stay clear of exhaust tip during regeneration. You or
others can be burned.
Note:OCR will not be allowed until DPF load percentage has reached at
least 80%. The DPF load percentage will fluctuate up and down when
driving your vehicle due to active and passive regenerations.
Note:OCR will not be allowed to operate if the service engine soon
light
is illuminated
Note:During the use of OCR, you may observe a light amount of white
smoke. This is normal.
Note:During stationary PTO operation, OCR will change the engine speed
to 2,000 or 2,400 rpm (depending on vehicle application), therefore it is
recommended you exit PTO mode before starting OCR. During mobile PTO
use, OCR is not necessary; regeneration will function normally.
