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.

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.
Minor Troubleshooting Guide
If the engine won ’t crank WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. 5
Super Duty (TFA) , enUSA Introduction
Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
dash-mounted upfitter switches that
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 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 50). 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:

Engine lubrication for severe service
operation
The following conditions define severe
operation for which engine operation with
SAE 5W-40 API CJ-4 is recommended. Oil
and oil filter change intervals will be
determined by the Intelligent Oil Life
Monitor™ as noted previously.
• Frequent or extended idling (over 10
minutes per hour of normal driving)
• Low-speed operation/stationary use
• If vehicle is operated in sustained
ambient temperatures below -10°F
(-23°C) or above 100°F (38°C)
• Frequent low-speed operation,
consistent heavy traffic less than 25
mph (40 km/h)
• Operating in severe dust conditions
• Operating the vehicle off road
• Towing a trailer over 1,000 miles (1,600
km)
• Sustained, high-speed driving at Gross
Vehicle Weight Rating (maximum
loaded weight for vehicle operation)
• Use of fuels with sulfur content other
than ultra-low sulfur diesel (ULSD)
• Use of high-sulfur diesel fuel
ENGINE COOLANT CHECK
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of engine coolant
at the intervals listed in the scheduled
maintenance chapter. See Scheduled
Maintenance (page 59). Note:
Make sure that the level is between
the MIN and MAX marks on the coolant
reservoirs.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See
Adding Engine Coolant
in this chapter.
Note: The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30 °F
(-34 °C) and -34 °F (-37 °C).
Note: For best results, the coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your dealer.
Ford does not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Engine Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, you can
be burned if you spill coolant on hot engine
parts. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.

Super Duty (TFA) , enUSA Maintenance
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
50
Super Duty (TFA) , enUSA MaintenanceE163372
air filter when the restriction gauge reads
near the change filter line and the gauge
is yellow. If you allow the restriction gauge
to reach maximum restriction you can
affect your engine performance and fuel
economy.
Note:
Do not blow out the air filter element
with compressed air since the compressed
air could damage the filter paper.
Note: Do not rely on filter appearance
alone. A filter which appears to be dirty may
actually have several thousand miles
(kilometers) of life remaining. After installation of the new filter element,
reset the gauge by pressing the reset
button on top of the gauge.
The following actions are recommend after
operating the vehicle up to 200 miles (320
km) in heavy 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.
• Extreme rain: The air filter will dry after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Air Filter Replacement
When replacing the air filter element, use
a Motorcraft® air filter element. See
Motorcraft Parts (page 55).
Note: Failure to use the correct air filter
element may result in severe engine
damage.
