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.
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
• 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
frame-mounted fuel filter should be
changed at the recommended service
interval or when indicated by the
information display LOW FUEL PRESSURE
message. See
Scheduled Maintenance
(page 319).
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
100).
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 or the information display
message WATER IN FUEL DRAIN FILTER
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.
8
F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing IntroductionE154903

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
Diesel Lubrication System
It is important to change the engine oil at
the recommended service intervals or
when indicated by the information display
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 218).
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. You can find more
information about coolant additives and
coolant change intervals in the coolant
chapter. See
General Maintenance
Information (page 319). Operating the
engine with insufficient coolant or coolant
additive can cause severe engine damage. 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 Reductant System (page 112).
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.
Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to the start position, the lights
become dim or go out, the battery
connections may be loose or corroded, or
the battery may be discharged. If there is
a clicking or stuttering sound coming from
the engine compartment when you turn
the key to the start position, this may also
indicate a loose or corroded battery
connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.

•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, See
Jump Starting the Vehicle (page 183).
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump.
• Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive •
Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter
If fuses burn out WARNING: Replacement fuses and
circuit breakers must always be the
same rating as the original equipment
shown. Never replace a fuse or circuit
breaker with one of a higher rating.
Higher rated fuses or circuit breakers
could allow circuit overloading in the
event of a circuit malfunction, resulting
in severe vehicle damage or personal
injury due to fire.
Burned-out or blown fuses usually indicate
an electrical short-circuit, although a fuse
may occasionally burn out from vibration.
Insert a second fuse. If this fuse
immediately burns out and you cannot
locate the cause, return your vehicle to
your dealer for a circuit check. See
Changing a Fuse
(page 201).
Selective catalytic reduction system
speed limit and Idle-only modes
If the vehicle ’s speed is limited or in an
idle-only mode, the selective catalytic
reduction system may be limiting the
vehicle ’s functions due to low or
contaminated DEF. Check the DEF. See
Selective Catalytic Reductant System
(page
112).

F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Information Displays

We recommend the use of Top Tier Diesel
fuel where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. Look for
the Top Tier logo at the station. For
additional information, visit
www
.t op tier g a s. c om .
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 significantly
increases exhaust emissions and reduces
engine life due to increased internal wear. Using low sulfur diesel fuel with
16-500 ppm or high sulfur diesel
fuel with greater than 500 ppm
in your diesel engine will cause certain
emission components to malfunction,
which could 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
authorized 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
with 16–500 ppm or high sulfur diesel fuel
with greater than 500 ppm in a diesel
engine requiring only Ultra Low Sulfur
Diesel fuel could 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 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.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
101
F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Fuel and Refueling

To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
•
Confirm the biodiesel content of the
fuel to be 20% biodiesel or less, also
known as B20.
• Only use biodiesel fuel of good quality
that complies with industry standards.
• Follow the recommended service
maintenance intervals. See
Scheduled Maintenance (page 319).
• 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.
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.
Use of biodiesel in concentrations greater
than 20% could cause damage to your
vehicle, including engine and/or exhaust
catalyst and particulate filter failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that could
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, also known as B5. Follow
the recommended oil change intervals and
other maintenance when operating on
biodiesel. See
Special Operating
Conditions Scheduled Maintenance
(page
329). 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.
Note:
Biodiesel fuels degrade more easily
than diesel fuels not containing biodiesel.
Degraded or oxidized biodiesel can damage
fuel system seals and plastics and corrode
steel parts. If you plan to park or store your
vehicle for more than 1 month, empty your
vehicle fuel tank of biodiesel fuel. Fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle for a minimum of
30 minutes.
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 Capacities and
Specifications (page 288).

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
