2012 FORD SUPER DUTY lock

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 numberslater in this chapter 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 separatorearlier in this
chapter.
To install the new DFCM filter, seeInstallation – DFCM filterlater in
this section.
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
numberslater in this chapter for the fuel filter kit part number.
2. 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 counterclockwise
until the peg aligns with the release
slot.
3. Pull the filter straight out 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.

1For severe duty usage, use SAE 5W-40 API CJ-4.
2For biodiesel (grades B6-B20) usage, use SAE 5W-40 or SAE
15W-40 API CJ-4.
An engine block heater is recommended at temperatures below –10°F
(–23°C).
A symbol has been developed by the
American Petroleum Institute (API)
to help you select the proper engine
oil. It will be included on the oil
container you purchase. The top
section of the symbol shows the oil
performance by the API designation. This should match the owner guide
recommendation. The center section will show the SAE viscosity grade
Changing the engine oil and oil filter
Your vehicle is equipped with an Intelligent Oil Life Monitor™ that
calculates the proper oil change service interval. When the message
center indicates:OIL CHANGE REQUIRED, change the engine oil and
oil filter. See theMessage centersection of theInstrument Cluster
chapter for more information.
Refer toMotorcraft part numberslater in this chapter for the engine oil
filter part number. This filter protects your engine by filtering harmful,
abrasive or sludge particles and particles significantly smaller than most
available “will-fit” filters.

•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 mix with recycled coolant. We do not recommend the
use of recycled coolant in vehicles equipped with Motorcraft
Speciality Engine Coolant, since a Ford approved recycling
process is not yet available.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system(s) are under pressure; steam and hot liquid can
come out forcefully when the cap is loosened slightly.
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 a 50/50 mixture of coolant and distilled water 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 a 50/50 mixture of coolant and distilled water to the
coolant reservoir until the coolant level is within the COLD FILL RANGE
as listed on the reservoir.

WARNING:Failure to maintain the functional holes, in the
tailpipe section of the exhaust, clean and free of debris or
foreign material may result in the holes becoming blocked or plugged.
Do not modify or remove the tail-pipe section. Blocked or plugged
holes or removal/modification of the system could result in elevated
exhaust gas temperatures which may result in vehicle/property damage
or personal injury.
WARNING:The normal operating temperature of the exhaust
system is very high. Never work around or attempt to repair any
part of the exhaust system until it has cooled. Use special care when
working around the diesel oxidation catalytic converter and/or the
diesel particulate filter (DPF). The diesel oxidation catalytic converter
and/or the DPF heats up to a high temperature after only a short
period of engine operation and can stay hot even after the engine is
turned off. Failure to follow these instructions may result in personal
injury.
EMISSION CONTROL SYSTEM(S) LAWS
In the U.S. federal law and certain state laws prohibit removing or
rendering inoperative emission control system(s). Similar federal or
provincial laws may apply in Canada. Ford recommends against any
vehicle modification without determining applicable 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. Provide adequate insulation. Failure to follow these
instructions may result in fire or personal injury.
Tampering with emissions control systems (including related sensors and
the diesel exhaust fluid (DEF) injection system) can result in reduced
engine power and the illumination of the service engine soon light
.
