2014 FORD SUPER DUTY service

ABOUT THIS SUPPLEMENT
This supplement 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 your Owner
’s
Manual included 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.
Note: 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 will stay in the system ’s
memory cannot be erased even if the
modification is removed. Ford Motor
Company, Ford of Canada, Ford of Mexico
and service or repair facilities can retrieve
this information when servicing your vehicle.
Ford Motor Company may use this
information to determine if your warranty
covers any needed repairs.
Note: Some aftermarket products may
cause severe engine/transmission and/or
exhaust system damage; refer to your
warranty information for more information.
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 Starting and Stopping the Engine
chapter, See Starting a Diesel Engine
(page 9). It is important to read and
understand this material in order to
maintain the best service life for your
engine. Ford may discontinue models or change
specifications without any notice and
without incurring obligations.
Warnings WARNING
Throughout this guide, you will find
warnings identified by the warning
symbol. Warnings remind you to be
especially careful to reduce the risk of
personal injury. 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 1000 miles
(1600 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.
See Technical Specifications (page 56
).
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. See Engine Oil Check (page
42
).
Diesel Engine Information
The diesel engine fuel system is a
pressurized two-stage filtration system
and consists of:
• A frame-mounted Fuel and Water
Separator 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
3
Super Duty (TFA) Introduction

•
A high-pressure fuel rail for each
cylinder bank (2 total)
• Numerous high-pressure pipes from
the high-pressure pump to the rails,
and rails to the injectors
The fuel and water separator 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 fuel and
water separator filter should be changed
at the recommended service interval or
when indicated by the information display
LOW FUEL PRESSURE message. Refer to
the scheduled maintenance information
in this supplement for more information.
The fuel and water separator should be
drained at regular intervals (recommended
at every oil change) or when indicated by
the information display and water in fuel
indicator light. See Fuel Quality (page
14).
Proper fuel filter maintenance and prompt
water draining when the water in fuel light
illuminates is essential to prevent injection
equipment damage. Ignoring the water in
fuel light can cause your vehicle to go into
a reduced power mode.
A frame-mounted electric fuel pump
located inside the fuel and water separator
draws fuel from the fuel tank to provide
pressurized fuel to the engine. The fuel
pump contains a pressure relief valve for
overpressure protection in the event of
restricted flow.
The fuel injection system is controlled
through the powertrain control module. 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
modified engine performance
characteristics are normal.
If these modified engine performance
characteristics persist for an extended
period and either the service engine soon
or powertrain malfunction,reduced power,
electronic throttle control light is
illuminated, have the system checked by
an authorized dealer.
Service engine soon
Powertrain malfunction, reduced
power, electronic throttle control
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. See
Engine Oil Check
(page 42).
Fast start glow plug system
The diesel engine glow system consists of:
• Eight glow plugs (one per cylinder)
• Glow Plug Control Module
• Engine Coolant Temperature sensor
• Barometric pressure sensor
• Environmental temperature sensor

Super Duty (TFA) Introduction

Operation in Snow and Rain
Vehicle operation in heavy snowfall or
extreme rain conditions may feed
excessive amounts of snow or water into
the air intake system. This could plug the
air filter with snow and may cause the
engine to lose power and possibly shut
down.
We recommend the following actions after
operating your vehicle up to 200 miles
(320 kilometers) in snowfall or extreme
rain:
•
Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do not
remove the foam filter) and reset the
air filter restriction gauge.
Note: Removal of the foam filter degrades
your vehicle performance during snow and
hot weather conditions.
• Extreme rain: The air filter dries after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Refer to Air filter and restriction gauge in
the Maintenance chapter for more
information. See Changing the Engine
Air Filter (page 49).
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 you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately. Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
SWITCHING OFF 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 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 the
Load Carrying chapter in your Owner
’s
Manual.
ENGINE IDLE SHUTDOWN
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 show ENGINE TURNS OFF
IN 30 (seconds) and start counting
down
• You can restart the five or 15-minute
timer 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 your information display

FUEL QUALITY
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)
Note:
Your warranty will not cover damage
caused by using an improper type of fuel or
fuel additive.
Note: Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel will
significantly increase your vehicle ’s exhaust
emissions and reduce engine life due to
increased internal wear.
You should use Ultra-Low Sulfur Diesel
fuel (also known as ULSD) designated as
number 1-D or 2-D with a maximum of
15-ppm sulfur in your diesel vehicle. You
may operate your vehicle on diesel fuels
containing up to 20% biodiesel, also
known as B20. These fuels should meet
the ASTM D975 diesel or the ASTM D7467
B6-B20 biodiesel industry specifications.
Outside of North America, use fuels
meeting EN590 or equivalent local market
standard. Using low sulfur diesel fuel
(16-500 ppm) or high sulfur
diesel fuel (greater than 500
ppm) in your diesel engine 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. 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 an 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 coolant
system damage, engine overheating,
selective catalyst reduction system or
diesel particulate filter damage and
possible base engine damage.
Use only a diesel engine 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 are only
available for sale in countries where ultra
low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in a ultra low sulfur
diesel fuel market that are subsequently
exported to non- ultra low sulfur diesel 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- ultra low sulfur diesel
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. You may operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
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. See General
Maintenance Information (page 58).
• 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
frequent LOW FUEL PRESSURE
message 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 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 the Special
operating conditions section under the
Schedule Maintenance chapter 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 you plan to park or
store your vehicle for more than 1 month,
then you should empty your vehicle fuel
tank of biodiesel fuel. You should fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle 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.

3.
Rotate the drain counterclockwise until
the O-ring is visible. Allow the diesel
fuel conditioner module to drain for
approximately 25 seconds or until
clean fuel is observed. Rotate the drain
clockwise to tighten it. If no liquid
drains, there may be a clog in the drain.
Have the conditioner module serviced
by an authorized dealer.
4. Make sure that you fully tighten the drain valve and then remove the
container from under your vehicle.
5. Restart the engine. If the WATER IN FUEL DRAIN FILTER or WATER IN FUEL
DRAIN FILTER SEE MANUAL message
and light continues to illuminate, have
the fuel system checked and repaired.
Low Fuel Pressure
The engine is equipped with a low fuel
pressure detection system. Here are some
possible causes if a low fuel pressure
message appears in the information
display:
• Cold start or during cold operation
(below 32°F (0°C): If the low fuel
pressure message appears during a
cold start or up to 10 minutes after the
initial cold start, monitor the
information display. If the low fuel
pressure message disappears and does
not re-appear after the engine has fully
warmed up, waxed or gelled fuel is what most likely caused the message.
Do not use alcohol based additives to
correct fuel gelling. This may result in
damage to the fuel injectors and
systems. Use an anti-gel additive. See
Technical Specifications (page 56).
Note: Your 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 low fuel
pressure message appears when your
vehicle is warm and during low fuel
tank level operation (near empty),
refuel your 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.
• Normal operation: If the low fuel
pressure message appears during
normal operation when the engine is
fully warm, and fuel level is not low,
you must change the fuel filters
regardless of the maintenance
schedule interval.
• If replacement of the fuel filter does
not remedy the low fuel pressure
message during normal operation as
defined above, take the vehicle to an
authorized dealer.
Changing the Engine-Mounted and
Diesel Fuel Conditioner Module Fuel
Filters
Your vehicle is equipped with two fuel
filters. The first filter mounts on top of the
engine on the driver ’s side. The second
filter, inside the diesel fuel conditioner
module, is mounted on the frame rail under
the driver ’s side floorboard near the
transmission. You should replace both
17
Super Duty (TFA) Fuel and RefuelingE163360

Note:
The engine will not run properly if you
do not install the diesel fuel conditioner
module fuel filter in the housing or if the
filter bowl is not tightened to the
mechanical stop.
Note: You will need to purge the system of
air after removal or changing of the filter.
See purging air from the fuel system later
in this chapter.
Removal - Engine-mounted fuel filter
The engine-mounted fuel filter is a plastic
disposable cartridge. To remove it, do the
following: 1.
Disconnect both fuel lines by squeezing
the connector tabs and pulling the lines
straight off. Note:
Although the fuel system is not fully
pressurized when the vehicle is off, some
residual pressure may remain in the fuel
system since it can take some time for the
pressure to completely bleed off. Therefore,
we recommend you place a shop rag below
the filter connectors to absorb the small
amount of fuel that will drain.
2. Rotate the filter fully counterclockwise
until the peg is at the far end of the slot.
3. Pull the filter straight up from the bracket and discard the filter.
Installation – Engine-mounted fuel
filter
1. Install the new filter into the filter bracket. Turn the filter clockwise to
lock it in place.
2. Reconnect both fuel lines.
Note: Using a fuel that has more than
average impurities may require you to
replace the fuel filter more frequently than
the service interval specifies.
Note: You will need to purge the system of
air after removal or changing of the filter.
See purging air from the fuel system later
in this chapter.
Purging air from the fuel system
Turn the ignition key to on for 30 seconds,
then turn it to off. Do this six times in a row
to purge any trapped air from the fuel
system.
After filter service, a no start or rough
running engine may indicate that air is
entering the system through the filter bowl
seal or drain. Make sure the drain is tight
and you tightened the filter bowl to the
mechanical stop.

SELECTIVE CATALYTIC
REDUCTION SYSTEM
Your vehicle is equipped with a selective
catalytic reduction system to help reduce
emission levels of oxides of nitrogen from
the exhaust of the diesel engine. The
system automatically injects diesel
exhaust fluid into the exhaust system to
enable proper selective catalytic reduction
function.
Importance of maintaining the
Diesel Exhaust Fluid level
In order for the selective catalytic reduction
system to operate properly, the diesel
exhaust fluid level must be maintained.
Generally, the diesel exhaust fluid tank
should be filled during the oil change
service interval. See General
Maintenance Information (page 58).
However, certain conditions or driving
styles, such as trailer towing or fast rates
of acceleration, will require the refilling of
the diesel exhaust fluid tank more often.
The engine control unit will monitor the
amount of fluid available in the diesel
exhaust fluid tank. Running a system check
in the message center will indicate whether
the diesel exhaust fluid level is ok or if it is
less than 1/2 full. A message will display in
the message center when the diesel
exhaust fluid level is low and needs to be
refilled. When you see this message, you
should refill your tank. See the Information
displays chapter of your Owner ’s Manual
for information display functions. For
instructions on refilling your diesel exhaust
fluid tank, see filling the diesel exhaust
fluid tank in this supplement. Diesel Exhaust Fluid warning
messages and vehicle operations WARNINGS
Diesel exhaust fluid 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 diesel exhaust fluid immediately. If
the diesel exhaust fluid becomes empty
or contaminated and fluid is not replaced,
your vehicle will become limited to idle
speed only once stopped. In these
conditions, be cautious where you stop
your vehicle because you may not be able
to drive long distances and will not be able
to maintain highway speeds until diesel
exhaust fluid is refilled or replaced. Tampering or disabling your vehicle
’s
exhaust aftertreatment system will
result in severe vehicle performance
limitation including eventual speed limiting
to 5 mph. Your vehicle
’s information display will
display a series of messages regarding the
amount of diesel exhaust fluid available.
A systems check will display messages
indicating the amount of diesel exhaust
fluid available (OK or under 1⁄2 full) or will
produce a warning message that displays
the mileage (kilometers) remaining as the
fluid in the diesel exhaust fluid tank nears
empty. For more information on warning
messages, see the Information Displays
chapter of your Owner ’s Manual. As the diesel exhaust fluid level
nears empty, the diesel exhaust
fluid warning symbol will be
displayed and chimes will sound with the
messages starting at 500 miles (805 km)
remaining before diesel exhaust fluid is
depleted. The warning symbol and
messages will continue until you refill the
diesel exhaust fluid tank.
