2004 FORD SUPER DUTY engine

After servicing the air filter element,
reset the restriction gauge by
pressing the button on the end of
the gauge.
Note:If the vehicle is operated in a
heavy snow storm, in blowing snow
or the vehicle is equipped with a
snowplow, the engine air filter
element may become partially
clogged with snow and/or ice. If this
occurs, the air filter restriction
gauge will move to the CHANGE FILTER mark and the engine may
experience a significant reduction in power output. The vehicle may be
driven under these conditions for up to 160 km (100 miles) without
damage to the engine or related components.
At the earliest opportunity, clear all snow and ice from the air induction
system and reset the restriction gauge by pressing the button on the end
of the gauge. If the air filter restriction gauge moves the CHANGE
FILTER mark after clearing snow and/or ice, then replace the filter.
Reset filter restriction gauge after changing the air filter element.
The air filter warning light on the instrument cluster may be used, in
addition to the underhood restriction gauge, to monitor the condition of
the air filter element. Refer to theEngine air filterwarning light in this
section of the supplement.

STARTING THE ENGINE
Read all starting instructions carefully before you start your vehicle.
For temperatures below 0°C (32°F), the use of the correct grade engine
oil is essential for proper operation.
If your vehicle is equipped with a manual transmission, make sure the
parking brake is set fully 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 set before you turn
the key. Do not press the accelerator during starting.
COLD WEATHER STARTING
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 cleaner decal). Such fluid could cause immediate
explosive damage to the engine and possible personal injury.
Note: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 4 (ON) without
turning the key to 5 (START).Do

2. When the glow plug pre-heat light
turns off, turn the key to 5
(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 light
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 3 (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.
Note:If the engine does not start within five seconds on the first try,
turn the key to 3 (OFF), wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
STOPPING THE ENGINE
Turn the ignition to OFF. 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.
COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and specificationschapter.
At temperatures below–7°C (20°F), Number 2–D Diesel fuel may
thicken enough to clog the fuel filter. Your vehicle is equipped with an
HFCM which acts as a fuel filter/heater/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 this bypass valve
to function and avoid engine fuel starvation, it is recommended that,
during cold weather operation 0°C (32°F) or below, the fuel level in your
Driving
12

tank should not be allowed to drop below 1/4 full. This will help prevent
air from entering the fuel system and stalling the engine.
In cold weather below 0°C (32°F) your Diesel 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.
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 cleaner with snow and
cause the engine to stall and/or lose power.
Refer toAir filter restriction gaugeandEngine air filterin the
Instrumentationchapter 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 your Owner Guide.
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.
