2012 FORD SUPER DUTY heater

If the vehicle’s speed is limited or the vehicle has entered an
idle-only mode
If the vehicle’s speed is limited or in an idle-only mode, the SCR system
may be limiting the vehicle’s functions due to low or contaminated diesel
exhaust fluid (DEF). Check the DEF. SeeSelective catalytic reduction
(SCR) systemin theMaintenance and Specificationschapter for more
information.
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 Motorcraftcetane 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
may remain on for a period of time after engine start. 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.

place. Remove any debris, snow and/or ice on the foam filter by brushing
the surface with soft brush. Do not use water, solvents, or a hard brush
for cleaning the foam filter.
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 the proper 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 listed in thescheduled maintenance information.
•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, especially in cold weather,
can cause a buildup of deposits which can cause engine damage.
The following cold weather idling guidelines are recommended:
•Use Motorcraftcetane improvers or non alcohol-based cetane
improvers from a reputable manufacturer.
•Maintain the engine cooling system properly.
•Avoid shutting the engine down after an extensive idling period. Drive
the vehicle for several miles with the engine at normal operating
temperatures under a moderate load.
•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 (if equipped) (refer to
Engine block heaterin theDrivingchapter of theOwner’s Guide) will
assist in engine starting in extreme cold ambient temperatures.
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.
Idle control:
•Your vehicle may have a factory option for a 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 and rain
Vehicle operation in heavy snowfall or extreme rain conditions may feed
excessive amounts of snow/water into the air intake system. This could
plug/soak the air filter with snow and may cause the engine to lose
power and possibly shut down.
The following actions are recommended after operating the vehicle up to
200 miles (320 km) in snowfall or extreme rain:
•Snow:At the earliest opportunity, open the hood and clear all the
snow and ice from the air filter housing inlet (do not remove the foam
filter) and reset the air filter restriction gauge.
Note:Removal of the foam filter degrades vehicle performance during
snow and hot weather conditions.
•Extreme rain:The air filter will dry after about 15–30 minutes at
highway speeds. At the earliest opportunity, open the hood and reset
the air filter restriction gauge.
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.
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 and the DTE (distance to
empty) will display the amount of
fuel in the currently selected tank.
INTEGRATED ENGINE BRAKING
This feature increases engine braking at higher engine speeds to provide
better grade descent control with less brake and transmission wear and
tear.
This feature is integrated with the tow/haul mode feature. When tow/haul
mode is switched on, the integrated engine braking feature will also be
active. For more information on tow/haul, seeAutomatic transmission
operationin theOwner Guide.

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.
