Care should be taken whenever diesel fuel is stored. Use only clean,
approved containers which will prevent the entry of dirt or water.
Diesel fuel must not be stored in a galvanized container. The fuel will
dissolve the zinc in a galvanized container. The zinc will then remain in
the solution until it is run through the engine where it will be deposited
in the fuel injectors causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
This truck is equipped with a fuel fill pipe which is able to accept fuel up
to 20 gallons per minute from a 1
1 8fuel dispensing nozzle. Pumping fuel
at greater flow rates may result in premature nozzle shut-off or spitback.
Fuel filler cap
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
WARNING:If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel tank may damage the
fuel system or cause the fuel cap to disengage in a collision, which may
result in possible personal injury.
Note:If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The vehicle warranty may be void
for any damage to the fuel tank or fuel system if the correct genuine
Ford or Motorcraft® fuel filler cap is not used.
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once.

Use only DEF certified by the
American Petroleum Institute (API)
such as Motorcraft® DEF or
equivalent meeting Ford
specification WSS-M99C130-A
and/or ISO 22241. Look for API
certification trademark shown here.
Repairs resulting from the use of
non-certified DEF products will not be covered by your vehicle’s
warranty.
Maintaining the purity of DEF is important to avoid malfunctions in the
SCR system.
If DEF is removed from the tank for repair work, etc., the same DEF
must not be used to refill the tank as its purity is no longer guaranteed.
To fill the DEF tank, see your authorized dealer or do the following
(before filling the DEF tank in cold climates, seeFilling the DEF tank
in cold climateslater in this section):
•DEF bottle fill with spout:
The following procedure applies to Motorcraft® DEF or similar DEF
bottles; for other brands or bottle types, refer to the instructions on the
bottle label.
1. Remove the cap from the DEF container. Remove the spout from the
bottle and insert the straw end into the bottle. Ensure that the arrow
above the nut is aligned with the bottle handle and the small tube end
extends into the far corner of the bottle. Twist the spout nut on the
container until it is tight.
2. Open the DEF filler port on the
vehicle by turning thebluecap
counterclockwise.Do not put DEF
in the fuel tank. This can cause
engine damage not covered by
your vehicle’s warranty.

3. Rotate the drain counterclockwise
until the O-ring is visible. Allow the
DFCM to drain for approximately
25 seconds or until clean fuel is
observed. Rotate the drain clockwise
to tighten it. If no liquid drains, the
drain may be clogged. Have the
DFCM serviced by your authorized
dealer.
4. Make sure that the drain valve is fully tightened, then remove the
container from under the vehicle.
5. Restart the engine. TheWATER IN FUEL DRAIN FILTERor

LOW FUEL PRESSURE MESSAGE
The engine is equipped with a low fuel pressure detection system. If the
message center displays:LOW FUEL PRESSUREthe following
explains why and what to do:
•Cold start or cold operation (below 32°F (0°C): If this message
appears during a cold start or during cold operation up to 10 minutes
after the initial cold start, monitor the message center. If it disappears
and does not re-appear after the engine has fully warmed up, the low
fuel pressure message is most likely caused by waxed or gelled fuel.
Do not use alcohol based additives to correct fuel gelling. This may
result in damage to the fuel injectors/systems. Use an anti-gel additive
as listed in theCapacities and Specificationschapter. The customer
warranty may be void from using additives that do not meet or exceed
Ford specifications.
If the low fuel pressure message persistently appears after re-fueling
during the cold start and cold operation conditions defined previously
and then disappear when the engine has fully warmed up, consider
different fuel sources.
•Low fuel operation: If the message appears when the vehicle is warm
and during low fuel tank level operation, i.e. the tank level is at or
very near empty, refuel the vehicle and operate the vehicle. If the
message reappears after fueling, see below. If the message does not
come back, the low fuel pressure condition was due to low fuel levels
in the fuel tank.

•Normal operation: If the message appears during normal operation
when the vehicle / engine is fully warm, and fuel level is not low, the
fuel filters must be changed regardless of the maintenance schedule
interval.
•If replacement of the fuel filter does not remedy the low fuel pressure
message during normal operation as defined above, take the vehicle to
your authorized dealer.
CHANGING THE ENGINE-MOUNTED AND DFCM FUEL FILTERS
Your vehicle is equipped with two fuel filters; one is mounted on top of
the driver’s side of the engine and the second filter, inside the DFCM, is
mounted on the frame rail under the driver-side floorboard near the
transmission. Both filters should be replaced at the same time. Regular
fuel filter changes are an important part of engine maintenance; failing to
keep with the scheduled maintenance could lead to engine performance
issues and/or fuel injection system damage. Refer to thescheduled
maintenance informationof this supplement for more information.
Refer toMotorcraft part numbersin theMaintenancechapter for the
fuel filter replacement part number. This part number includes filters
and seals for both the engine-mounted and frame-mounted filters.
Removal - DFCM filter
The DFCM filter is located in the lower portion of the DFCM housing.
1. Drain the DFCM. SeeFuel filter/water separatorin theFuel and
Refuelingchapter.
To install the new DFCM filter, seeInstallation – DFCM filterin the
Fuel and Refuelingchapter.
2. Remove the lower portion of the
DFCM housing (filter bowl) by
turning it counterclockwise using a
32 mm socket.
Note:Depending on the amount
seal swelling, removal of the filter
bowl may be noisy and require some
effort. Replace the seal prior to
reinstalling the filter/bowl to
improve assembly.
3. Remove and discard the old fuel filter element.
4. Carefully clean the mating surfaces using a lint-free rag.

Installation – DFCM filter
1. Install the new filter into the filter bowl tabs and replace the seal on
the DFCM header (top portion of DFCM). Refer toMotorcraft part
numbersin theMaintenancechapter for the fuel filter kit part number.
2. Lube O-ring with lubricant packet in the filter kit. This will assist in
making sure the filter gets properly tightened.
3. Reinstall the lower portion of the
housing by slowly turning it
clockwise onto DFCM housing,
allowing fuel to soak into the fuel
filter element. Tighten the lower
housing until it contacts the
mechanical stop.
Note:The engine will not run
properly if the DFCM fuel filter is
not installed in the housing or if the
filter bowl is not tightened to the
mechanical stop.
The system will need to be purged of air after removal/changing of the
filter. SeePurging air from the fuel system after DFCM and engine
mounted fuel filter replacementfollowing.
Removal - Engine-mounted fuel filter
The engine-mounted fuel filter is a plastic disposable cartridge. To
remove it, do the following:
1. Disconnect both fuel lines by
squeezing the connector tabs and
pulling the lines straight off.
Note:Although the fuel system is
not fully pressurized when the
vehicle is off, some residual
pressure may remain in the fuel
system since it can take some time
for the pressure to completely bleed
off. Therefore, it is recommended to
place a shop rag below the filter
connectors to absorb the small amount of fuel that will drain.

2. Rotate the filter fully
counterclockwise until the peg is at
the far end of the slot.
3. Pull the filter straight up from the bracket and discard the filter.
Installation – Engine-mounted fuel filter
1. Install the new filter into the filter bracket. Turn the filter clockwise to
lock it in place.
2. Reconnect both fuel lines.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.
The system will need to be purged of air after removal/changing of the
filter. SeePurging air from the fuel system after DFCM and
engine-mounted fuel filter replacementfollowing.
Purging air from the fuel system after DFCM and engine mounted
fuel filter replacement
Turn the ignition key to on for 30 seconds, then turn it to off. Do this a
total of six times in a row to purge any trapped air from the fuel system.
After filter service, a no start or rough running engine may indicate that
air is entering the system through the filter bowl seal or drain. Make sure
the drain is tight and the filter bowl has been tightened to the
mechanical stop.
DIESEL EXHAUST SYSTEM: OXIDATION CATALYST/DIESEL
PARTICULATE FILTER SYSTEM
Your vehicle is equipped with a diesel particulate filter (DPF). The DPF
is an inline filter in the exhaust system which reduces carbon emissions
by trapping exhaust particles before they reach the tailpipe. The DPF
looks similar to a traditional exhaust catalyst, except larger, and is part
of the exhaust system under the vehicle. The DPF is coupled to a diesel
oxidation catalyst, that reduces the amount of harmful exhaust emitted

•Do not use alcohol, methanol or brine or any engine coolants mixed
with alcohol or methanol antifreeze (coolant). Alcohol and other
liquids can cause engine damage from overheating or freezing.
•Do not add extra inhibitors or unapproved additives to the coolant.
These can be harmful and compromise the corrosion protection of the
engine coolant.
Add prediluted engine coolant meeting the Ford specification
(Motorcraft® Orange Antifreeze/Coolant Prediluted). SeeCapacities
and Specificationsfor more information. Note: Generic coolants for all
makes and models may not meet the Ford specification and may cause
damage to the cooling system. This damage may void the warranty.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add prediluted engine coolant
(Motorcraft® Orange Antifreeze/Coolant Prediluted) to the FULL COLD
level. For all other vehicles which have a coolant degas system with a
pressurized cap, or if it is necessary to remove the coolant pressure
relief cap on the radiator of a vehicle with an overflow system, follow
these steps to add engine coolant.
1. Turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise until pressure begins to release.
3. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
4. Fill the coolant reservoir slowly with prediluted engine coolant to
within the FULL COLD level, or between the MIN and MAX marks
(within the COLD FILL RANGE), as listed on the engine coolant
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full. If coolant is
added to bring the level within the COLD FILL RANGE when the engine
is not cold, the system may remain under filled.
5. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.

If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low level
of coolant can result in engine overheating and possible engine damage.
Engine and secondary cooling system refill procedure
The following procedure should be used when refilling the engine or
secondary cooling systems after it has been drained or become extremely
low.
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Slowly add prediluted engine coolant to the coolant reservoir until the
coolant level is within the COLD FILL RANGE as listed on the reservoir.
6. Reinstall the pressure relief cap.
7. Start and run the engine at 2,000 rpm for 2 minutes.
8. Shut engine off, and remove the pressure relief cap as previously
outlined.
9. If required, add prediluted engine coolant to the coolant reservoir until
the coolant level is within the COLD FILL RANGE as listed on the
reservoir.
10. Engine cooling system: Repeat Step 5 until the coolant level has
stabilized (is no longer dropping after each step) AND the upper radiator
hose at the radiator is warm to the touch (indicating that the engine
thermostat is open and coolant is flowing through the radiator).
Secondary cooling system: Repeat Step 5 until the coolant level has
stabilized (is no longer dropping after each step) AND the lower
passenger side of the secondary radiator is warm to the touch
(indicating secondary thermostat is open and coolant is flowing
through the entire system).
11. Reinstall the pressure relief cap. Shut the engine off and let it cool.
12. Check the coolant level in the reservoir before you drive your vehicle
the next few times (with the engine cool).
