Diesel Engine 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
The powertrain and glow plug control
modules electronically control the glow
plug system. After you switch the ignition
on, the glow plug control module
immediately energizes the glow plugs. The
glow plug control module uses the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor to determine how long the glow
plugs stay energized. The required time for
the glow plugs to be energized decreases
as the coolant temperature, barometric
pressure and environmental temperature
increase.

Automatic Engine Shutdown
If your vehicle is equipped with a keyless
ignition, it has a feature that automatically
shuts down the engine if it has been idling
for an extended period. The ignition also
turns off in order to save battery power.
Before the engine shuts down, a message
appears in the information display showing
a timer counting down from 30 seconds.
If you do not intervene within 30 seconds,
the engine shuts down. Another message
appears in the information display to
inform you that the engine has shut down
in order to save fuel. Start your vehicle as
you normally do.
Cold Weather Starting
WARNINGS
Do not use starting fluid, for example
ether, in the air intake system. Such
fluid could cause immediate
explosive damage to the engine and
possible personal injury. Do not add gasoline, gasohol, alcohol
or kerosene to diesel fuel. This
creates a serious fire hazard and
causes engine performance problems. We recommend that the engine block
heater be used for starting when the
temperature is -9°F (-23°C) or colder. See
Engine Block Heater (page 183).
When operating in cold weather, you may
use Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from
a reputable manufacturer as needed. Switch the ignition on. Do not
start the engine until the
glow-plug indicator turns off. When the glow plug pre-heat indicator
turns off, turn the key to start. After you
start the engine, the glow plugs may
remain on for a period. If you do not start
the engine before the glow plug activation
time ends, you will need to reset the glow
plugs by switching the ignition off. After
the engine starts, allow it to idle for about
15 seconds. This protects the engine. Do
not increase engine speed until the oil
pressure gauge indicates normal pressure.
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.
Change to a lighter grade engine oil to
make starting easier under these
conditions. Refer to engine oil
specifications. See
Capacities and
Specifications (page 432).
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 and system. Use the proper
anti-gel and performance improvement
product. See
Capacities and
Specifications (page 432).
180
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Starting and Stopping the Engine

Your vehicle has a fuel and water separator
that 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, we
recommend that the fuel level in your tank
should not drop below ¼ full. This helps
prevent air from entering the fuel system
and stalling the engine.
Your vehicle has a selective catalytic
reduction system that uses Diesel Exhaust
Fluid (DEF) to operate properly. You need
to replenish your vehicle ’s DEF at certain
intervals. When filling your vehicle ’s DEF
tank in cold weather, take special care to
prevent damage to the tank. See
Selective Catalytic Reductant System
(page
198).
In cold weather below
32°F (0°C), the
engine may slowly increase to a higher idle
speed if you leave it idling in park (P). As
the engine warms-up, the engine sound
level decreases due to the activation of
PCM-controlled sound reduction features.
If you operate your vehicle in a heavy
snowstorm or blowing snow conditions,
snow and ice can clog the engine air
induction. If this occurs, the engine may
experience a significant reduction in power
output. At the earliest opportunity, clear
all the snow and ice away from inside the
air filter assembly. Remove the air cleaner
cover and the air filter and remove any
snow or ice. Remove any debris, snow or
ice, on the foam filter by brushing the
surface with a soft brush. Once you have
cleared all of the debris, reinstall the air
filter and cover.
Do not use water, solvents, or a hard brush
for cleaning the foam filter. WARNING
To reduce the risk of vehicle damage
and personal burn injuries, do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running. 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
protecting 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 the Special
operating conditions section listed in
the scheduled maintenance
information.
• At temperatures of
-9°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.
181
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Starting and Stopping the Engine

We recommend the following cold
weather idling guidelines:
•
You can use Motorcraft® cetane
improvers or non-alcohol-based
cetane improvers from a reputable
manufacturer as needed.
• Maintain the engine cooling system
properly.
• Avoid shutting the engine down after
an extensive idling period. Drive your
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.
Winter Operating Tips for Arctic
Operation -20°F (-29°C) and Below
The following information is a guideline
only and is not to be the only source of
possible solutions in resolving extreme
cold temperature issues.
Starting Aids WARNING
Do not use starting fluid, for example
ether, in the air intake system. Such
fluid could cause immediate
explosive damage to the engine and
possible personal injury. The use of the factory engine block heater
assists in engine starting in extreme cold
ambient temperatures See Engine Block
Heater (page 183). Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
the upfitter switches in the overhead
console. This allows the operator to
elevate the idle RPM for extended idle
periods, as well as aftermarket equipment
such as PTO operation. You must configure
this feature even if ordered from the
factory. See your authorized dealer for
required upfitting.
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 mi
(320 km) 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 363).

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
- 6.7L DIESEL
Switch the ignition off.
To help prolong engine life, we
recommended you allow the engine to idle
for three to five minutes, especially after
any of the following:
•
Continuous engine speed.
• High ambient temperature.
• High GVW or GCW operation, for
example heavy loads or trailers.
This allows the turbo charged engine to
cool down.
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
ENGINE TURNED OFF
• One minute after the engine has shut
down, the electrical system simulates
key off, even though the ignition is still
in the on position, initiating normal
accessory delay period
• You must move the ignition to the off
position to reset the system before
restarting your vehicle.
The engine idle shutdown idle timer does
not start if:
• The engine is operating in power
take-off mode.
• The engine coolant temperature is
below 60°F (16°C).
• The exhaust emission control device is
regenerating.
ENGINE BLOCK HEATER
(If
Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. 183
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Starting and Stopping the Engine

Note:
The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
For cold climates that are below
0°F
(-18°C) needing a temporary battery
installation. Order the cold climate pack.
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source. We recommend that you do the following
for a safe and correct operation:
•
Make sure your vehicle is parked in a
clean area, clear of combustibles.
• locate the block heater cord in the front
tow hook pocket.
• Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard. •
Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray
and fire. The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury. Automotive fuels can cause serious
injury or death if misused or
mishandled.
Flow of fuel through a fuel pump
nozzle can produce static electricity.
This can cause a fire if you are filling
an ungrounded fuel container. Fuel may contain benzene, which is
a cancer-causing agent.
When refueling always shut the
engine off and never allow sparks or
open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. Observe the following guidelines when
handling automotive fuel:
•
Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Always turn off the vehicle before
refueling. •
Automotive fuels can be harmful or
fatal if swallowed. Fuel such as
gasoline is highly toxic and if
swallowed can cause death or
permanent injury. If fuel is swallowed,
call a physician immediately, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
visible for hours.
• Avoid inhaling fuel vapors. Inhaling too
much fuel vapor of any kind can lead
to eye and respiratory tract irritation.
In severe cases, excessive or prolonged
breathing of fuel vapor can cause
serious illness and permanent injury.
• Avoid getting fuel liquid in your eyes. If
fuel is splashed in the eyes, remove
contact lenses (if worn), flush with
water for 15 minutes and seek medical
attention. Failure to seek proper
medical attention could lead to
permanent injury.
• Fuels can also be harmful if absorbed
through the skin. If fuel is splashed on
the skin, clothing or both, promptly
remove contaminated clothing and
wash skin thoroughly with soap and
water. Repeated or prolonged skin
contact with fuel liquid or vapor causes
skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing gasoline vapors could cause
an adverse reaction, serious personal
injury or sickness. If fuel is splashed on
the skin, wash the affected areas
immediately with plenty of soap and
water. Consult a physician immediately
if you experience any adverse reactions.

FUEL QUALITY - E85
Choosing the Right Fuel - Flex Fuel
Vehicles
Flex fuel vehicles have one of the following
identifiers:
•
Yellow fuel filler cap.
• Yellow bezel around the fuel filler inlet.
• Yellow fuel filler housing.
• Yellow E85 label on the fuel tank filler
door. Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87 or
regular unleaded gasoline blended with a
maximum of 85% ethanol (E85).
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing (page 272).
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage. We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. For
additional information, refer to
www.toptiergas.com.
Note:
Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuels containing more than 85%
ethanol or E100 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
186
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Fuel and RefuelingE161513

Switching Between E85 and
Gasoline
We do not recommend repeatedly
alternating between E85 and gasoline. If
you switch from using E85 to gasoline, or
from gasoline to E85, add as much fuel as
possible, at least half a tank. Drive your
vehicle immediately for a minimum of 5 mi
(8 km) to allow it to adapt to the change
in ethanol concentration. If you use E85
exclusively, we recommend that you fill
the fuel tank with regular unleaded
gasoline at each scheduled oil change.
FUEL QUALITY - DIESEL
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)
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.
Note: The vehicle Warranty does 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. 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
19°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.
187
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Fuel and Refueling

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 mix diesel with gasoline,
gasohol or alcohol. This could cause
an explosion.
Note:
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. Red dye is used to identify
fuels intended for agricultural and
non-highway use. Damage to the fuel
injection system, engine and exhaust
catalyst can occur if an improper fuel is
used.
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
Scheduled Maintenance (page 581).
• 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.
