2004 FORD SUPER DUTY heater

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.
