•On F-Super Duty vehicles (6.4L engine),a frame-mounted
Horizontal Fuel Conditioner Module (HFCM)
•an engine-mounted secondary fuel filter
•a unit injector for each cylinder
The FCM/HFCM acts as a primary fuel filter/water separator which
removes both water and impurities from the fuel. The engine-mounted
fuel filter and the FCM/HFCM filter should be changed at the
recommended service interval. Refer to thescheduled maintenance
informationin this supplement for more information.
The FCM/HFCM should be drained at regular intervals or when the
WATER IN FUEL light illuminates in the instrument cluster (E-Series) or
when the WATER IN FUEL message appears in the message center
(F-Super Duty).
The fuel injectors are located in the center of the combustion chambers
in the cylinder head between the rocker arm assemblies. The glow plug
system and fuel injection system are controlled through the Powertrain
Control Module (PCM) and Fuel Injection Control Module (FICM) (6.0L
engine only).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump.
The fuel pump provides pressurized fuel to the engine and is
electronically controlled by the fuel pump PCM relay. The fuel pump
contains a pressure relief valve for overpressure protection in the event
of restricted flow.
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 features are
intended to modify engine performance characteristics. If these modified
engine performance characteristics persist for an extended period or the
Check Engine (
) or Powertrain malfunction/Reduced
power/Electronic throttle control light (
) is illuminated, seek
service from your authorized dealer.
Lubrication system
Extended oil change intervals can negatively affect engine performance,
fuel economy and engine life. Refer to the engine oil specification chart
located underEngine oil specificationsin theMaintenance and
Specificationschapter of this supplement.

F-Super Duty w/automatic transmission
Note:Some Warning Lights are reconfigurable telltale (RTT) indicator
lights and will illuminate in the Message Center Display and function the
same as the warning light.
Glow plug pre-heat indicator:
With the key in the ON position,
the
light will illuminate if glow
plug heat is necessary as a starting aid. Wait until the light goes off
before starting. Refer toCold weather startingin theDrivingchapter
of this supplement. After the engine starts, the light should turn off. The
light should always illuminate at least momentarily when the engine is
cold and the ignition is turned to ON. If it does not illuminate, the glow
plug system should be checked and repaired promptly to avoid difficulty
in cold starting.
Water in fuel:

During refueling, it is possible for water-contaminated diesel fuel to be
pumped into your tank. Your vehicle’s fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL RTT will illuminate when the ignition is turned to START (as part
of the light function check) and when the FCM/HFCM has a significant
quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer toDraining the FCM/HFCM and changing the engine and
vehicle fuel filtersin theMaintenance and Specificationschapter of
this supplement for the drain procedure. Allowing water to stay in the
system could result in extensive damage to, or failure of, the fuel
injection system.
Do not drain the water separator while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.
Engine oil pressure (F-Super
Duty only):
Illuminates when the oil pressure
falls below the normal range. Refer
toEngine oilin theMaintenance
and Specificationschapter for more information.
Engine air filter (F-Super Duty only):
The engine air filter warning
message comes on in the message
center when the air filter restriction
gauge reaches the CHANGE FILTER
mark or if the air filter and/or
housing becomes packed with snow.
If airflow is restricted because of snow ingestion, the indicator will
remain on until snow is cleared from the housing, but the vehicle will
still be functional.
The air filter condition should be verified by inspecting the underhood
restriction gauge; the message is only a secondary indicator. Always use
the underhood restriction gauge to determine when the air filter element
needs to be changed.

The vehicle may be driven with the engine air filter message on or when
the underhood air filter restriction gauge has moved to the CHANGE
FILTER mark for up to 200 miles (320 km) without damaging the engine.
However, the air filter element must be replaced at the earliest
opportunity. Refer toAir filter restriction gauge and air filter
replacementin theMaintenance and Specificationschapter for more
information.
GAUGES
Engine boost gauge (F-Super Duty):
Indicates the amount of pressure in
the engine. Driving with your
pointer continuously at the high end
of the scale may damage the engine.

AIR FILTER RESTRICTION GAUGE AND AIR FILTER
REPLACEMENT
Air filter restriction gauge:
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 the hood is raised to
perform general engine maintenance
at least every 7,500 miles (12,000 km). If the vehicle is operated in
extremely dusty conditions, check the gauge at least every 500 miles
(800 km), or two weeks, whichever comes first.
Change the air filter when the gauge reads 25 inches (635 mm). Engine
performance and fuel economy are adversely affected when the
maximum restriction is reached.
Blowing-out the air filter element with compressed air is not
recommended as the compressed air may damage the filter paper.
Note:It is not possible to determine the level of filter clogging by visual
appearance alone. A filter which appears to be dirty may actually have
several thousand miles (kilometers) of life remaining.
Always use the underhood air filter restriction gauge to
determine when the air filter element needs to be changed. The
warning light on the instrument cluster should not be used
exclusively for determining when the air filter element needs
changing.

After installation of the new filter
element, reset the gauge by pressing
the reset button on top of the
gauge.
Note:If the vehicle is operated in a
heavy snow storm, in blowing snow
or the vehicle is equipped with a
snowplow, the engine air filter
element may become partially
clogged with snow and/or ice. If this
occurs, the engine may experience a
significant reduction in power output. The vehicle may be driven under
these conditions for up to 200 miles (320 km) without damage to the
engine or related components.
At the earliest opportunity, clear all snow and ice from the air induction
system and reset the restriction gauge by pressing the button on the end
of the gauge. If the air filter restriction gauge vacuum reads above the
second line after clearing snow and/or ice, then replace the filter. Reset
filter restriction gauge after changing the air filter element.
The air filter warning message on the instrument cluster may be used, in
addition to the underhood restriction gauge, to monitor the condition of
the air filter element. Refer to theEngine air filterwarning light in this
chapter of the supplement.
Air filter replacement:
When replacing the air filter element, use the Motorcraft air filter
element listed inMotorcraft Part Numberslater in this chapter.
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.
Failure to use the correct air filter element may result in severe
engine damage.
•E-series air filter element:
1. Disconnect the hoses from the air filter outlet tube.
