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

Cold Weather Starting
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. WARNING:
Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
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 176).
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 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
Engine Block Heater
(page 176).
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
Engine Block Heater (page
176).

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) WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock.

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 if you
use a high quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
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 and system. See Engine
Specifications (page 429).
Your warranty may not cover repairs
needed to correct the effects of using an
aftermarket product that does not meet
Ford specifications in your fuel.
RUNNING OUT OF FUEL WARNING:
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.
Avoid running out of fuel because this
situation may have an adverse effect on
engine components. If you have run out of fuel:
•
You may need to cycle the ignition from
off to on several times after refueling
to allow the fuel system to pump the
fuel from the tank to the engine. On
restarting, cranking time will take a few
seconds longer than normal. With
keyless ignition, just start the engine.
Crank time will be longer than usual.
• Normally, adding
1 gal (4 L) of fuel is
enough to restart the engine. If the
vehicle is out of fuel and on a steep
grade, more than
1 gal (4 L) may be
required.
REFUELING - GASOLINE WARNING: 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. WARNING:
Fuel vapor burns
violently and a fuel fire can cause severe
injuries. WARNING: Read and follow all the
instructions on the pump island. WARNING:
Stay outside your
vehicle and do not leave the fuel pump
unattended when refueling your vehicle. WARNING:
Keep children away
from the fuel pump. Never let children
pump fuel. WARNING:
Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank.

filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes. WARNING: Do not allow people or
animals in truck beds that have
modifications, such as bed covers or
slide-in campers, when the engine is
running. Exhaust fumes are toxic. Failure
to follow this instruction could result in
personal injury or death.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 317).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Your vehicle warranty does not cover
resulting component damage.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.

Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly, for example, the bulb
does not work, or if the OBD-II system has
determined that some of the emission
control systems have not been properly
checked. In this case, the vehicle is not
ready for I/M testing.
If you have just serviced the vehicle ’s
engine or transmission or the battery has
recently run down or you have replaced it,
the OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.
SELECTIVE CATALYTIC
REDUCTANT SYSTEM - DIESEL
Your vehicle may have a selective catalytic
reduction system. The system helps reduce
emission levels of oxides of nitrogen from
the exhaust system. The system
automatically injects diesel exhaust fluid
into the exhaust system to enable correct
selective catalytic reduction system
function.
Note: Selective catalytic reduction systems
are not fitted to vehicles in markets where
only high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctly
you must maintain the diesel exhaust fluid
level.
A warning message appears in the
information display when the diesel
exhaust fluid level is low. If a warning
message appears, refill the diesel exhaust
fluid tank as soon as possible. See
Information Messages (page 120).
191
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Engine Emission Control

Note:
For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you repair the contaminated system.
To service a contaminated or inoperative
system, see an authorized dealer.
DIESEL PARTICULATE FILTER
The filter forms part of the emissions
reduction system on your vehicle. It filters
harmful diesel particulates (soot) from the
exhaust gas.
Regeneration WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard.
Note: Avoid running out of fuel.
Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function. Your vehicle will carry
out this process automatically. If your journeys meet one of the following
conditions:
•
You drive only short distances.
• You frequently switch the ignition on
and off.
• Your journeys contain a high level of
acceleration and deceleration.
You must carry out occasional trips with
the following conditions to assist the
regeneration process:
• Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.
• Avoid prolonged idling and always
observe speed limits and road
conditions.
• Do not switch the ignition off.
• Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM.
Oxidation Catalytic Converter and
Diesel Particulate Filter System
(If
Equipped) WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel
particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.
