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.

safety belt. After Step 4, the safety belt
warning light flashes for confirmation.
• This will switch the feature off for that
seating position if it is currently on.
• This will switch the feature on for that
seating position if it is currently off.
CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
restraint seatbelts to make sure there are
no nicks, tears or cuts. Replace if
necessary. All vehicle seatbelt assemblies,
including retractors, buckles, front seatbelt
buckle assemblies, buckle support
assemblies (slide bar-if equipped),
shoulder belt height adjusters (if
equipped), shoulder belt guide on seat
backrest (if equipped), child safety seat
LATCH and tether anchors, and attaching
hardware, should be inspected after a
crash. Read the child restraint
manufacturer's instructions for additional
inspection and maintenance information
specific to the child restraint.
We recommend that all seatbelt
assemblies in use in vehicles involved in a
crash be replaced. However, if the crash
was minor and an authorized dealer finds
that the belts do not show damage and
continue to operate properly, they do not
need to be replaced. Seatbelt assemblies
not in use during a crash should also be
inspected and replaced if either damage
or improper operation is noted.
Properly care for seatbelts. See Vehicle
Care (page 255). SEATBELT EXTENSIONS WARNING:
Persons who fit into
the vehicle's seatbelt should not use an
extension. Unnecessary use could result
in serious personal injury in the event of
a crash. WARNING:
Only use extensions
provided free of charge by our dealers.
The dealer will provide an extension
designed specifically for this vehicle,
model year and seating position. The use
of an extension intended for another
vehicle, model year or seating position
may not offer you the full protection of
your vehicle's seatbelt restraint system. WARNING:
Never use seatbelt
extensions to install child restraints. WARNING:
Do not use a seatbelt
extension with an inflatable seatbelt. WARNING:
Do not use extensions
to change the way the seatbelt fits
across the torso, over the lap or to make
the seatbelt buckle easier to reach.
If, because of body size or driving position,
it is not possible to properly fasten the
seatbelt over your lap and shoulder, an
extension that is compatible with the
seatbelts is available free of charge from
our dealers. Only use our seatbelt
extensions made by the original equipment
seatbelt manufacturer with our seatbelts.
Ask your authorized dealer if your extension
is compatible with your vehicle restraint
system.
