WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. Certain fluids contained in vehicles and certain
products of components contain or emit chemicals known to the State
of California to cause cancer and birth defects or other reproductive
harm.
WARNINGS
Throughout this guide, you will find warnings. Warnings remind you to
be especially careful to avoid personal injury.
NEW VEHICLE BREAK-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,600 km (1,000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 800 km (500 miles) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin theGeneral
Maintenance Informationchapter for more information on oil usage.

DIESEL ENGINE INFORMATION
The Diesel engine fuel system consists of:
•a frame-mounted electric fuel supply pump
•an engine mounted fuel filter/water separator
•a fuel restriction sensor
•a unit injector for each cylinder
The combination fuel filter/water separator removes both water and
impurities from the fuel. The filter should be changed at the
recommended service interval. Refer to the scheduled maintenance guide
for more information. The filter bowl should be drained at regular
intervals or when the WATER IN FUEL light illuminates in the
instrument cluster.
The fuel injectors are located in the center of the combustion chambers
in the cylinder head between the rocker arm assemblies. The glow plug
system and fuel injection system are controlled through the Powertrain
Control Module (PCM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump.
The fuel pump provides pressurized fuel to the engine and is
electronically controlled by the fuel pump PCM relay. The fuel pump
contains a pressure relief valve for overpressure protection in the event
of restricted flow.
Lubrication system
It is important to change the engine oil at the recommended service
intervals, because oil viscosity is important in maintaining the oil
pressure required to actuate the fuel injectors. Extended oil change
intervals can negatively affect engine performance and fuel economy.
Pressurized oil from the turbocharger is also used to actuate an exhaust
backpressure warm-up system (if equipped). Pressurized oil from the
turbocharger is routed to the exhaust backpressure actuator. During
exhaust backpressure operation, the engine’s sound will be altered and
you may notice a change in engine performance while it’s engaged. This
function occurs only during cold weather warm-up cycle.
Fast start glow plug system
The glow plug system consists of:
•eight glow plugs
•the glow plug relay

The air filter element should be
replaced when the colored band on
the gauge reaches the CHANGE
FILTER mark. Engine performance
and fuel economy are adversely
affected when maximum restriction
is reached. After servicing the air
filter element, reset the restriction
gauge by pressing the button on the
end of the gauge.
Air filter restriction gauge, F-250/350/450/550 & Excursion
The restriction gauge, located on
the upper housing of the air cleaner
assembly, monitors the condition of
the air filter element in two ways:
First, the colored indictor inside the
gauge highlights the percentage that
the air filter element is clogged with
dust or contaminants. Refer to
Engine CompartmentinService
Pointschapter.
Second, the gauge contains an electrical switch which illuminates a
warning light on the instrument cluster when the air filter element is
100% clogged. Refer toF-250/350/450/550, ExcursioninWarning
Lightschapter.
Check the air filter restriction gauge whenever the hood is raised to
perform general engine maintenance. If the vehicle is operated in
extremely dusty conditions, check the gauge at least every 800 km (500
miles), or two weeks, whichever comes first.
The air filter element must be
replaced when the colored band on
the gauge reaches the CHANGE
FILTER mark. Engine performance
and fuel economy are adversely
affected when the maximum
restriction is reached.

WATER IN FUEL
•E-Series
•F-250/350/450/550, Excursion
During refueling, it is possible for water-contaminated diesel fuel to be
pumped into your tank. Your vehicle fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL light will illuminate when the ignition is turned to START (as part
of the light function check) and when the fuel filter/water separator has
a significant quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the filter bowl.
Refer to theGeneral maintenancechapter for drain procedure.
Allowing water to stay in the system could result in extensive damage to,
or failure of, the fuel injection system.
Do not drain the water separator while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.
ENGINE AIR FILTER (F-250/350/450/550 & EXCURSION)
The engine air filter warning light
illuminates when the air filter
restriction gauge reaches the
CHANGE FILTER mark.
The vehicle may be driven with the engine air filter warning light
illuminated for up to 400 km (250 miles) without damaging the engine or
related components. However, the air filter elementmustbe replaced at
the earliest opportunity. Refer toAir filter restriction gaugein the
Diesel informationchapter for more information.

4. When the engine starts, release the key. The glow plugs will continue
to be activated for up to two minutes. If the engine is not started before
the activation ceases, the glow plug system must be reset by turning the
ignition key to OFF.
5. 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 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 theGeneral
maintenance informationchapter.
At temperatures below–7°C (20°F), Number 2–D Diesel fuel may
thicken enough to clog the fuel filter. Your engine is equipped with 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 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
in-tank fuel sending unit, 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 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). The sound of the engine
may change also, as an exhaust device engages to improve heater
performance and reduce exhaust smoke.

SCHEDULED MAINTENANCE
The Scheduled Maintenance Services in the scheduled maintenance
guide are required because they are considered essential to the life and
performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle.
CLEANING THE ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•The engine must be cool to the touch before spraying with water.
•Never spray a hot engine with cold water, as damage to the
engine block or engine components may occur.
•Use caution when using a self-serve power washer (1,000 psi
maximum pressure) to clean the engine, as the high-pressure fluid
could penetrate the sealed parts and cause damage.
•Never apply anything to any exposed belts in the engine
compartment, including the belt dressing.
For general cleaning of the engine and engine compartment, spray
Engine Shampoo (ZC-20) on all parts that require cleaning and pressure
rinse the area with cool water.
Cover the highlighted areas to prevent water damage when cleaning the
engine(never wash or rinse the engine while it is running; water
in the running engine may cause internal damage):
