2010 FORD SUPER DUTY fuel filter

•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
filter filters finer impurities from the diesel 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.
F-Super Duty
E-Series
The FCM/HFCM should be drained at regular intervals or when the
WATER IN FUEL light illuminates in the instrument cluster.
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
service engine soon
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.
On E-Series vehicles (6.0L engine),it is important to change the
engine oil at the recommended service intervals because oil viscosity is
important in maintaining the oil pressure required to actuate the fuel
injectors.
On F-Super Duty vehicles (6.4L engine),it is important to change
the engine oil at the recommended service intervals to maintain oil
viscosity with the addition of the diesel particulate filter (DPF).
Fast start glow plug system
The glow plug system consists of:
•eight glow plugs
•the glow plug control module (GPCM)
•engine oil temperature (EOT) sensor
•barometric pressure (BARO) sensor
The glow plug system is
electronically controlled by the
PCM. The GPCM energizes the glow
plugs immediately after the ignition
is placed in the ON position, then determines how long the glow plugs
will be on according to the EOT and BARO sensors. The required time
for the glow plugs to be energized decreases as the engine oil
temperature and barometric pressure increase.
Engine cooling system
The engine cooling system contains an engine oil cooler and an Exhaust
Gas Recirculation (EGR) cooler. The oil cooler’s function is to regulate
engine oil temperature. The EGR cooler function is to cool exhaust gases
before they are circulated back through the engine to reduce emissions.
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. Refer to the Special
Operating Conditions section for more information about coolant
additives and coolant change intervals. Operating the engine with
insufficient coolant and/or coolant additive can cause severe engine
damage.

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 on. 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:
F-Super Duty
E-Series
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
light will illuminate 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 fuel filtersin the
Maintenance 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.
WARNING: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.

Cold weather starting
It is recommended that the engine block heater be used for starting
when the temperature is -10°F (-23°C) or colder. Refer toEngine block
heater (if equipped)in theDrivingchapter of theOwner’s Guide.
When operating in cold weather, use Motorcraft Cetane improvers or non
alcohol-based Cetane improvers from a reputable manufacturer.
Do not crank the engine for more than 10 seconds as starter damage
may occur. If the engine fails to start, turn the key to 3 (off) and wait
30 seconds before trying again.
WARNING:Do not use starting fluid, such as ether, in the air
intake system (see air filter decal). Such fluid could cause
immediate explosive damage to the engine and possible personal injury.
WARNING:Do not add gasoline, gasohol or alcohol to diesel
fuel. This practice creates a serious fire hazard and causes
engine performance problems.
1. Turn the key to on without turning the key to start.Do not start the
engineuntil the glow-plug pre-heat indicator
turns off.
2. When the glow plug pre-heat
indicator turns off, turn the key to
start, then release the key as soon
as the engine starts. The glow plugs
will continue to be activated for two minutes after the glow plug pre-heat
indicator
has turned off. If the engine is not started before the
glow plug activation time ends, the glow plugs will need to be reset by
turning the key to off.
3. After the engine starts,allow it to idle for about 15 seconds. This
is to protect the engine. Do not increase engine speed until the oil
pressure gauge indicates normal pressure.

COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and Specificationschapter of this supplement.
Diesel fuel is adjusted seasonally for cold temperatures. Diesel fuel which
has not been properly formulated for the ambient conditions may form
wax crystals which can clog the fuel filter. At temperatures below 20°F
(–7°C), if the engine starts, stalls after a short time, and then will not
restart, the fuel filter(s) may be clogged. For best results in cold
weather, use a diesel fuel which has been formulated for the ambient
conditions. If you have been using biodiesel, you may need to use a fuel
with lower biodiesel content, try another brand, or discontinue using
biodiesel.
Your vehicle is equipped with either an FCM or HFCM which recirculates
fuel from the engine to help prevent fuel filter clogging. Your vehicle is
also equipped with a bypass relief valve, located in the fuel tank pick-up
boot, which provides fuel flow to the engine if the fuel pickup should
become plugged. To allow the bypass valve to function and avoid engine
fuel starvation during cold weather operation of 32°F (0°C) or below, it
is recommended that the fuel level in your tank should not be allowed to
drop below
14full. This will help prevent air from entering the fuel
system and stalling the engine.
In cold weather below 32°F (0°C), the engine will slowly increase to a
higher idle speed if left idling in P (Park). As the engine warms-up, the
engine sound level will decrease due to the activation of PCM-controlled
sound reduction features.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs, the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all the snow
and/or ice away from inside the air filter assembly. Take the top off the
assembly, leaving the air filter in, and remove any snow or ice.
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 Motorcraft Premium Engine Coolant solution at the concentration
recommended to protect 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.

(exhaust catalyst and particulate filter) failures. Concentrations greater
than 5% can also cause fuel filter restrictions that may result in a lack of
power and or damage to components such as fuel tank, fuel lines, fuel
pump, fuel sender and fuel injectors fuel pump and fuel injector failures.
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,
B5 indicates a fuel containing 5% 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.
Biodiesel should not be stored in the fuel tank for more than three
months. If your vehicle will be parked or stored for more than three
months, then your vehicle should be drained and filled with a diesel fuel
not containing biodiesel.
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.
Biodiesel use may affect the recommended oil change intervals. Refer to
theSpecial operating conditionssection in theschedule maintenance
guidefor more information about oil change intervals and other
maintenance when operating on biodiesel.
Biodiesel fuel is a product that has been converted from renewable fuel
sources, including vegetable oil, animal fat and cooking oil. Raw or
refined vegetable oil, animal fat, cooking oil or recycled greases should
NOTbe used.
WARNING:Do not use home heating oil, agricultural fuel or any
diesel fuel not intended for highway use. Damage to the fuel
injection system, engine and exhaust catalyst can occur if an improper
fuel is used. Do not add gasoline, gasohol or alcohol to diesel fuel. This
practice creates a serious fire hazard and engine performance
problems.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets the ASTM D
975 industry specification. Aftermarket additives can damage the injector
system or engine. Repairs to correct the effects of using an aftermarket
product in your fuel may not be covered by your warranty.
