STARTING THE ENGINE
Read all starting instructions carefully before you start your vehicle.
For temperatures below 32°F (0°C), the use of the correct grade engine
oil is essential for proper operation. Refer toEngine oil specifications
in theMaintenance and Specificationschapter for more information.
If your vehicle is equipped with a manual transmission,make sure
the parking brake is fully set before you turn the key. Depress the clutch
pedal and place the gearshift in the neutral position. The clutch must be
fully depressed in order to operate the starter. Do not press the
accelerator during starting.
If your vehicle is equipped with an automatic transmission,ensure
the gearshift lever is in P (Park) and the parking brake is fully set before
you turn the key. Do not press the accelerator during starting.
Engine-driven cooling fan (Fan clutch)
Your vehicle is equipped with an engine driven cooling fan drive (also
called a fan clutch). This fan drive changes the fan speed to match the
vehicle’s changing cooling air flow requirements. Fan speed, fan noise
level and fuel consumption all will increase based on the driving
conditions that include trailer towing, hill climbing, heavy loads, high
speed and high ambient temperature, individually or in combination. The
fan drive is designed to provide the minimum fan speed (and resulting
fan noise and fuel consumption) required to meet the ever changing
vehicle cooling air flow requirements. You will hear the amount of fan
noise increasing and decreasing as the engine power requirements and
vehicle driving conditions change as you drive. This is to be expected as
being normal to the operation of your vehicle. High levels of fan noise
might also be heard when your engine is first started, and should
normally decrease after driving for a short time.
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 toUsing the
engine block heater (if equipped)in theDrivingchapter of the
Owner’s Guide.
When operating in cold weather, use a minimum of 45 Cetane Diesel fuel
or use Cetane improvers from a reputable manufacturer.
Do not crank the engine for more than 30 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.

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.
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. Do not
increase engine speed until the oil pressure gauge indicates normal
pressure.
STOPPING THE ENGINE
Turn the ignition to 3 (OFF).
On E-Series vehicles:To prolong engine life (after extended high
speed or maximum GVW operation), it is recommended that a hot engine
be allowed to operate at low idle for about 7–10 minutes which would
allow sufficient time for the turbocharged engine to cool down.
On F-Super Duty vehicles:To prolong engine life (especially after
extended high speed, high ambient temperature, or high GVW/GCW
operation), it is recommended that a hot engine be idled for 3-5 minutes
which will allow the turbocharged engine to cool down.
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.
At temperatures below 20°F (–7°C), Number 2–D diesel fuel may thicken
enough to clog the fuel filter. Your vehicle is equipped with either an

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.
