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 using the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor will 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.
Glow Plug
Engine and secondary cooling system
The cooling system contains a primary
cooling loop to cool the engine and a
secondary cooling loop to cool the
transmission, 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. For more information
about coolant additives and coolant
change intervals See Engine Coolant
Check (page 45). . Operating the engine
with insufficient coolant or coolant additive
can cause severe engine damage
Diesel Particulate Filter system
Your vehicle is equipped with a diesel
particulate filter in the exhaust system. The
diesel particulate filter reduces carbon
emissions by trapping exhaust particulates
(soot) before they reach the tailpipe. You
must properly maintain your diesel
particulate filter in order for it to function properly. Regeneration of the diesel
particulate filter occurs automatically
during operation above 30 mph (48 km/h)
and requires no actions from the driver. If
you do a lot of idling or stop and go driving,
pay attention to maintenance messages
that alert you when you need to drive to
clean the diesel particulate filter, or
perform operator commanded
regeneration. See
Emission Control
System (page 30).
Selective catalytic reduction system
Your vehicle is equipped with a selective
catalytic reduction system designed to
reduce emission levels of nitrogen oxides
from the exhaust of your diesel engine. This
system relies on the use of Diesel Exhaust
Fluid (DEF) that you must replenish at
certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes
contaminated will result in vehicle speed
limitations or result in your vehicle entering
an idle-only mode. See
Selective
Catalytic Reduction System (page 21).
Speed control
If your vehicle speed goes outside a
predetermined range from the set speed,
the RSM (Resume) function will not reset
your vehicle speed. You will need to reset
your vehicle speed with the SET+ or SET-
button after reaching the desired speed
using the accelerator pedal.

WARNING
To reduce the risk of vehicle damage
and/or personal burn injuries do not
start your engine with the air filter
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 -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 The following cold weather idling
guidelines are recommended:
•
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.

•
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
filters at the same time. Regular fuel filter
changes are an important part of engine
maintenance; failing to keep with the
scheduled maintenance could lead to
engine performance issues and fuel
injection system damage. Refer to the
scheduled maintenance information of this
supplement for more information. See
General Maintenance Information
(page 59). Refer to Motorcraft part numbers in the
Capacities and Specifications chapter for
the fuel filter replacement part number.
See Motorcraft Parts (page 55). This part
number includes filters and seals for both
the engine-mounted and frame-mounted
filters.
Removal - Diesel Fuel Conditioner
Module filter
The diesel fuel conditioner module filter is
located in the lower portion of the housing.
1. Drain the diesel fuel conditioner
module. See Draining the Fuel and
Water Separator earlier in this chapter.
2. Remove the lower portion of the diesel
fuel conditioner module housing (filter
bowl) by turning it counterclockwise
using a 32 mm socket. Note:
Depending on the amount of seal
swelling, removal of the filter bowl may be
noisy and require some effort. Replace the
seal prior to reinstalling the filter bowl to
improve assembly.
3. Remove and discard the old fuel filter element.
4. Carefully clean the mating surfaces using a lint-free rag.

Super Duty (TFA) , enUSA Fuel and RefuelingE163361

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 (DEF) into the exhaust
system to enable proper selective catalytic
reduction function. Importance of maintaining the
Diesel Exhaust Fluid (DEF) level
In order for the selective catalytic reduction
system to operate properly, the DEF level
must be maintained. Generally, the DEF
tank should be filled during the oil change
service interval. See General
Maintenance Information (page 59).
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 information
display will indicate whether the DEF level
is ok or if it is less than 1/2 full. A message
will display in the information display when
the DEF 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 DEF tank, see
filling the Diesel Exhaust Fluid (DEF) tank
in this supplement.
Diesel Exhaust Fluid (DEF)
warning messages and vehicle
operations WARNINGS
Diesel Exhaust Fluid (DEF) must be
refilled when low or replaced when
contaminated or your 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 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 you refill
or replace the DEF.

Fueling Tips WARNING
Do not use starting fluid such as
ether or gasoline in the diesel air
intake system. Such fluids can cause
immediate explosive damage to the engine
and possible personal injury. Truck stops have pumps and nozzles
designed for larger, heavy-duty trucks.
When refueling at truck stops: if the nozzle
shuts off repeatedly when refueling, wait
5–
10 seconds; then use a slower rate of
flow (don ’t depress the nozzle trigger as
far). If air is allowed to enter the fuel system
(during fuel filter change or if you run out
of fuel) the engine will purge the trapped
air as it runs. To purge the air sooner: prior
to engine start, prime the system by turning
the key to on for 30 seconds then to off.
Repeat this several times. The engine may
run rough and produce white smoke while
air is in the system. This is normal.
An engine that suddenly becomes noisy or
operates poorly after a fuel fill could be
using substandard fuel (for example, high
water content, low cetane rating or
gasoline in the fuel). You should purchase
diesel fuel from a reputable station that
sells a large amount of diesel fuel.
Use only clean, approved containers that
will prevent the entry of dirt or water
whenever you store diesel fuel.
Diesel fuel must not be stored in a
galvanized container. The fuel will dissolve
the zinc in the galvanized container. The
zinc will then remain in the fuel. If you run
the contaminated fuel through the engine,
the zinc will deposit in the fuel injectors
causing expensive-to-repair damage.

Diesel fuel dispensing nozzle fill rate
Your truck is equipped with a fuel fill pipe
that is able to accept fuel up to 20 gallons
per minute from an 11⁄8 fuel-dispensing
nozzle. Pumping fuel at greater flow rates
may result in premature nozzle shut-off or
spit back.
Fuel filler cap
WARNINGS
The fuel system may be under
pressure. If the fuel filler cap is
venting vapor or if you hear a hissing
sound, wait until it stops before completely
removing the fuel filler cap. Otherwise, fuel
may spray out and injure you or others. 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. Note:
If you must replace the fuel filler cap,
replace it with a fuel filler cap designed for
your vehicle. The vehicle warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft® fuel filler cap is not used.
Your fuel tank filler cap has an indexed
design with a 1/4 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the
cap with the notches on the filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once. EMISSION CONTROL SYSTEM
Diesel Exhaust System: Oxidation
Catalyst And Diesel Particulate
Filter System (If Equipped)
Your vehicle is equipped with a diesel
particulate filter. The diesel particulate
filter is an inline filter in the exhaust system
that reduces carbon emissions by trapping
exhaust particles before they reach the
tailpipe. The diesel particulate filter looks
similar to a traditional exhaust catalyst,
except larger, and is part of the exhaust
system under the vehicle. The filter couples
to a diesel oxidation catalyst that reduces
the amount of harmful exhaust emitted
from the tailpipe. As soot gathers in the
system, it begins to restrict the filter. You
need to periodically clean the soot that
gathers inside the filter. You can clean the
soot in two different ways, passive
regeneration and active regeneration. Both
methods occur automatically and require
no actions from the driver. During either
one of these regeneration methods, you
may notice a change in exhaust tone. At
certain times, the information display will
display various messages related to the
diesel particulate filter. See the Information
Displays chapter in the Owner Guide for
more information.
Passive regeneration
In passive regeneration, the exhaust
system temperature and constituents
automatically clean the filter, or reduce
the soot level, by burning (oxidizing) the
soot. Cleaning occurs naturally because of
normal engine operating conditions (at
varying levels, due to driving patterns).

Information display procedure
Start with your vehicle engine fully warmed
and then press the Info button on the
steering wheel until the information display
reads one of the following choices:
• EXHST XX% FULL CLEAN? Y/N
• EXHAUST FULL CLEAN? Y/N
Answer yes to this prompt and then follow
the prompts regarding exhaust position as
needed to initiate Operator Commanded
Regeneration. Be sure to understand each
prompt. If you are not sure what is being
asked by each prompt, contact an
authorized dealer. The display will confirm
the operation has started and when it has
finished.
If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning will
display
EXH AT LIMIT CLEAN? Y/N.
Answer yes to this prompt and then follow
the prompts regarding exhaust position as
needed to initiate Operator Commanded
Regeneration. Be sure to understand each
prompt. If you are not sure what is being
asked by each prompt, contact an
authorized dealer. The display will confirm
the operation has started and when it has
finished. You can also drive to clean the
filter. See Active regeneration earlier in this
chapter. When the system is at the point
of oversaturation, the service
engine soon light will illuminate
and the following message
EXH OVER
LIMIT SERVICE NOW will appear . You
will not be able to allow cleaning. You
must have your vehicle serviced by an
authorized dealer. Once operator commanded regeneration
starts, the engine
’s rpm will rise to
approximately 2,000 - 2,400 rpm and the
cooling fan will increase speed; you will
hear a change in audible sound due to the
fan and engine speed increase.
It is not necessary to open the hood on the
engine compartment. Once Operator
Commanded Regeneration is complete,
the engine rpm and fan will return to
normal idling. The exhaust system will
remain very hot for several minutes even
after regeneration is complete. Do not
reposition the vehicle over materials that
could burn until the exhaust system has
had sufficient time to cool. Depending on
the amount of soot collected by the diesel
particulate filter, ambient temperature,
and altitude, Operator Commanded
Regeneration may last from 10 to 25
minutes.
How to interrupt or cancel Operator
Commanded Regeneration
If you need to cancel the Operator
Commanded Regeneration, pressing the
brake, accelerator, or shutting off the
vehicle will stop the procedure. Depending
on the amount of time you allowed the
Operator Commanded Regeneration to
operate, soot may not have had sufficient
time to be eliminated, but the exhaust
system and exhaust gas may still be hot.
If you shut your vehicle off during Operator
Commanded Regeneration, you will notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal.
Filter service and maintenance
Over time, a slight amount of ash will build
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be removed
for ash cleaning at approximately 120,000
miles (193,000 km) or greater (actual

Scheduled Maintenance
The scheduled maintenance services in
the scheduled maintenance information
of this supplement are required because
they are considered essential to the life
and performance of your vehicle. See
General Maintenance Information
(page 59).
Use only recommended fuel, lubricants,
fluids and service parts conforming to Ford
specifications. Motorcraft® parts are
designed and built for best performance
in your vehicle.
ENGINE OIL CHECK
Because it is normal to add some oil
between oil changes, check your engine oil
level each time you stop for fuel. To check
the engine oil level consistently and
accurately, the following procedure is
recommended:
1. Have engine at normal operating temperature (at least into the NORMAL
range on the engine coolant
temperature gauge).
2. Park the vehicle on a level surface, then
turn off the engine and open the hood.
3. Allow at least 20 minutes after engine
shutdown to ensure that the oil
contained in the upper parts of the
engine has returned to the oil pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it clean and
reinsert fully.
5. Read oil level on both sides of dipstick
and use highest level (reading) for the
actual engine oil level. 6. Maintain the oil level within the
crosshatch area on the dipstick by
adding oil as required. Do not overfill
the oil past the maximum line as
depicted by the arrow.
Engine Oil Specifications
To help achieve acceptable engine
performance and durability, it is important
that only engine oils of good quality are
used in your diesel engine and it is changed
at the recommended interval. For normal
or severe service, use Motorcraft® oil or an
equivalent oil conforming to Ford
specifications as listed in the Capacities
and Specifications chapter. See
Technical Specifications
(page 57). It
is important to use these oils because they
are compatible with the emission control
equipment of your vehicle to meet the
more stringent emission standards.
The use of correct oil viscosities for diesel
engines is important for satisfactory
operation. Determine which oil viscosity
best suits the temperature range you
expect to encounter for the next service
interval from the following SAE viscosity
grade chart.
43
Super Duty (TFA) , enUSA MaintenanceE163369

Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. The
optional information display, if equipped,
will also display the message COOLANT
CHANGE REQUIRED at this time.
See Capacities and Specifications
(page 55). for the proper coolant.
Engine-driven Cooling Fan (Fan
Clutch)
Your vehicle is equipped with an engine
driven cooling fan drive (also called a fan
clutch). This fan drive changes the fan
speed to match the vehicle ’s changing
cooling air flow requirements. Fan speed,
fan noise level and fuel consumption all
will increase based on the driving
conditions that include trailer towing, hill
climbing, heavy loads, high speed and high
ambient temperature, individually or in
combination.
The fan drive is designed to provide the
minimum fan speed (and resulting
minimum fan noise and fuel consumption)
required to meet the ever changing vehicle
cooling air flow requirements. You will hear
the amount of fan noise increasing and
decreasing as the engine power
requirements and vehicle driving conditions
change as you drive. This is to be expected
as being normal to the operation of your
vehicle. High levels of fan noise might also
be heard when your engine is first started,
and should normally decrease after driving
for a short time. CHANGING THE ENGINE AIR
FILTER
Air Filter Restriction Gauge WARNING
To reduce the risk of vehicle damage
and/or personal burn injuries do not
start your engine with the air filter
removed and do not remove it while the
engine is running. Note:
Operating your vehicle in heavy
snowfall or extreme rain conditions may
allow excessive amounts of snow or water
into the air intake system. This could plug
or soak the air filter that could cause the
engine to lose power or shut down. The restriction gauge, located on the upper
housing of the air filter assembly, measures
the vacuum inside the air filter. The more
the air filter is restricted (dirty, clogged),
the higher the vacuum reading.
Check the air filter restriction gauge
whenever you open the hood to perform
general engine maintenance or at least
every 7,500 miles (12,000 km). If you
operate your vehicle in extremely dusty
conditions, check and reset the gauge at
least every 500 miles (800 km), or two
weeks, whichever comes first. Change the
