FCM (E-Series) or an HFCM (F-Super Duty) which acts as a fuel
filter/water separator to keep the wax melted which will help prevent
fuel filter clogging. However, if the engine starts but stalls after a short
time and will not restart, the fuel filter(s) may be clogged. For best
results in cold weather, use Number 1–D diesel fuel or “winterized”
Number 2–D diesel fuel which has an additive to minimize wax
formation.
Your vehicle is also equipped with a bypass relief valve, located on the
fuel control module, which provides fuel flow to the engine if the fuel
pickup should become plugged by ice or wax. To allow the bypass valve
to function and avoid engine fuel starvation, it is recommended that,
during cold weather operation 32°F (0°C) or below, the fuel level in your
tank should not be allowed to drop below
1 4full. 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 Gold 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.
•Make sure you use proper cold weather engine oil and that it is at its
proper level. Also, if necessary, make sure to follow the engine oil and
filter change schedule found under theSpecial Operating Conditions
section in theScheduled Maintenance Guidechapter.
•At temperatures of -10°F (-23°C) or below, it is recommended that
you use an engine block heater to improve cold engine starting.

•If operating in arctic temperatures of -20°F (-29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Note:Idling in cold weather will not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a buildup of heavy deposits of carbon and rust on valve stems causing
them to stick, which in turn, can cause valve train damage.
The following cold weather idling guidelines must be followed:
•Avoid idling the engine for more than 10 minutes at a time.
•Use Motorcraft Cetane improvers or non alcohol-based Cetane
improvers from a reputable manufacturer.
•Maintain the engine cooling system properly.
•Do not shut the engine down after an extensive idling period (10
minutes or more). Drive the vehicle for several miles with the engine
at normal operating temperatures under a moderate load to burn off
any accumulated carbon and varnish.
•Consider using an engine block heater.
•For extended idle times use an approved idle speed increase device.
Winter operating tips for Arctic operation -20°F (-29°C) and below
The following information is provided as a guideline only, and is not
intended to be the only source of possible solutions in resolving extreme
cold temperature issues.
Starting aids:
The use of the factory engine block heater (refer toUsing the engine
block heater [if equipped]in theDrivingchapter of theOwner’s
Guide) and oil pan heaters (aftermarket) will assist in engine starting, in
extreme cold ambient temperatures.
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.
Idle control:
For periods of extended idle, the throttle should be set at an rpm that is
sufficient to keep the engine at normal operating temperatures. This
action can reduce the amount of engine damaging deposits.

•The engine contains a unique “Cold Weather - Idle up feature”
calibration strategy within the PCM. Under the appropriate conditions,
the strategy will automatically elevate the engine idle speed after 130
seconds of idling in cold ambient temperatures. For this feature to be
activated, the truck must be in P (Park) (for automatic transmission),
in neutral (for manual transmission) with the parking brake applied
and engine oil temperature below 158°F (70°C). This strategy raises
the rpm to a level that reduces the potential to produce “coking” or
“wet stacking”, which is common to all diesel engines when idling for
extended periods during cold ambient temperatures.
•On F-Super Duty vehicles,a factory option for Stationary Elevated
Idle Control (SEIC) through dash-mounted Upfitter switches will allow
the operator to elevate the idle rpm for extended idle periods, as well
as aftermarket equipment such as PTO operation. This feature must
be configured even if ordered from the factory. See your authorized
dealer for required upfitting.
Operation in snow
Vehicle operation in heavy snowfall or in dry loose snow that may swirl
around the front of the vehicle may feed excessive amounts of snow into
the air intake system. This could plug the air filter with snow and cause
the engine to stall and/or lose power.
Refer toAir filter and restriction gaugein theMaintenance and
Specificationschapter of this supplement for more information.
Operation in standing water
Ingestion of water into the diesel engine can result in immediate and
severe damage to the engine. If driving through water, slow down to
avoid splashing water into the intake. If the engine stalls, and ingestion
of water into the engine is suspected, do not try to restart the engine.
Consult your dealer for service immediately.
Engine block heater (if equipped)
Refer to theDrivingchapter in theOwner’s Guide.
Rapid Heat supplemental heating system (if equipped)
The optional Rapid Heat feature is an electrically powered device that is
designed to provide supplemental heat during engine warm up. For
maximum effectiveness mid to low blower speed is recommended during
initial warm up. When operating in automatic mode (when equipped) the
climate control unit will determine the appropriate blower speed for
existing conditions.

Note:Additional aftermarket electrical loads operated during engine
warm up may impact the performance of the Rapid heat supplemental
heater.
DUAL FUEL TANK SELECTOR CONTROL (IF EQUIPPED)
If your vehicle is equipped with dual
fuel tanks, you will have a selector
control, located to the right of the
steering wheel, which allows you to
draw fuel from either tank. Your fuel
gauge will display the amount of
fuel in the currently selected tank.
Fuel level indication is delayed for several minutes when the tank
selector switch is actuated. Fuel level indication can be obtained
immediately by turning off and restarting the engine.

JUMP STARTING YOUR VEHICLE (E-SERIES ONLY)
The following procedure is for E-Series vehicles only. F-Super
Duty vehicles equipped with the 6.4L diesel engine can be jump
started using the same procedure as a gasoline engine; refer to
yourOwner’s Guidefor the jump starting procedure.
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; damage to the
automatic transmission may result.
Preparing your vehicle
When the batteries are disconnected or new batteries are installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the batteries of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the passenger side of the disabled
vehicle making sure the two vehiclesdo nottouch. Set the parking
brake on both vehicles.
Note:This vehicle has two frame-mounted batteries located on the
passenger side frame rail, behind the front passenger door. A battery
positive (+) jumper stud is located on the frame rail behind the rear
most battery box.

4. Make the final connection of the negative (-) cable to an exposed
metal part of the disabled vehicle’s frame or chassis, away from the
batteries.Do notuse fuel lines, brake lines, exhaust components or the
battery trays asgroundingpoints.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.
5. Ensure that the cables are clear of moving parts or any fuel delivery
system, brake system or exhaust system parts.
Jump starting
1. Start the engine of the booster vehicle and run the engine at
moderately increased speed.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run both engines for an
additional three minutes before disconnecting the jumper cables.

3. Remove the jumper cable from the positive (+) terminal of the booster
vehicle’s battery.
4. Remove the jumper cable from the positive (+) jumper stud of the
disabled vehicle. Reinstall the cap onto the jumper stud.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearnits idle conditions.

ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
•Cover the highlighted areas to prevent water damage when cleaning
the engine.

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
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.
