Warnings
WARNING: Throughout this guide,
you will find warnings identified by the
warning symbol. Warnings remind you
to be especially careful to reduce the risk
of personal injury.
Diesel Engine Information
The diesel engine fuel system is a
pressurized two-stage filtration system
and consists of:
• A frame-mounted Fuel and Water
Separator primary filter with an electric
fuel pump and water drain
• An engine-mounted secondary fuel
filter
• A fuel injector for each cylinder (8
total)
• A high-pressure fuel pump
• A high-pressure fuel rail for each
cylinder bank (2 total)
• Numerous high-pressure pipes from
the high-pressure pump to the rails,
and rails to the injectorsThe fuel and water separator removes
both water and impurities from the fuel.
The engine-mounted filter filters finer
impurities from the diesel fuel. The
engine-mounted fuel filter and the
frame-mounted fuel filter should be
changed at the recommended service
interval or when indicated by the
information display LOW FUEL PRESSURE
message. See Scheduled Maintenance
(page 319).
The fuel and water separator should be
drained at regular intervals (recommended
at every oil change) or when indicated by
the information display and water in fuel
indicator light. See Fuel Quality (page
106).
Proper fuel filter maintenance and prompt
water draining when the water in fuel light
illuminates is essential to prevent injection
equipment damage. Ignoring the water in
fuel light or the information display
message WATER IN FUEL DRAIN FILTER
can cause your vehicle to go into a reduced
power mode.
A frame-mounted electric fuel pump
located inside the fuel and water separator
draws fuel from the fuel tank to provide
pressurized fuel to the engine. The fuel
pump contains a pressure relief valve for
overpressure protection in the event of
restricted flow.
The fuel injection system is controlled
through the powertrain control module.
Engine Protection Mode
Ford diesel engines are equipped with
engine protection and emission control
systems. These systems monitor critical
temperatures and pressures, and modify
engine operation accordingly. These
modified engine performance
characteristics are normal.

Environment

Engine Oil Pressure Gauge
Indicates engine oil pressure. At normal
operating temperature, the level indicator
is in the normal range. If the pressure gauge
falls below the normal range, stop your
vehicle, switch off the engine and check
the engine oil level. Add oil if needed. If the
oil level is correct, have your vehicle
checked by an authorized dealer.
Engine Coolant Temperature
Gauge
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator is in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
possible, switch off the engine and let the
engine cool.
Fuel Gauge
The fuel gauge indicates about how much
fuel is in the fuel tank.
The arrow adjacent to the fuel pump
symbol indicates on which side of your
vehicle the fuel filler door is located.
Note:The fuel gauge may vary slightly
when your vehicle is moving or on a slope.Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty
reaches 50 mi (80 km), 25 mi (40 km),
10 mi (20 km) and 0 mi (0 km) for all
vehicle keys.
Note:The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Distance to Empty
Indicates the approximate distance your
vehicle can travel on the fuel remaining in
the tank. Changes in driving pattern can
cause the value to not only decrease but
also increase or stay constant for periods
of time.
Configurable Gauge
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator is in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop your vehicle as soon
as possible and verify the airflow is not
restricted by snow or debris blocking
airflow through the grille.
Special operating conditions such as
snowplowing, towing, or off-road use may
cause higher than normal operating
temperatures. See Special Operating
Conditions Scheduled Maintenance
(page 329).
To lower the transmission temperature
into the normal range, alter the severity of
your driving conditions. Operating the
transmission for extended periods with the
gauge in the higher than normal area may
cause internal transmission damage. If the
gauge continues to show high
temperatures, see an authorized dealer.

personal injury or sickness may result.
If you splash fuel on your skin, promptly
wash your skin thoroughly with soap
and water. Consult a physician
immediately if you experience an
adverse reaction.
Low Fuel Pressure (If Equipped)
Diesel engine vehicles have a low fuel
pressure detection system.
The following are possible causes for a low
fuel pressure warning message to appear
in the information display:
• Cold start or during cold operation
below 32°F (0°C). If the low fuel
pressure message appears during a
cold start or up to 10 minutes after the
initial cold start, monitor the
information display. If the low fuel
pressure message disappears and does
not re-appear after the engine has fully
warmed up, waxed or gelled fuel is
what most likely caused the message.
Do not use alcohol based additives to
correct fuel gelling. This may result in
damage to the fuel injectors and
systems. Use an anti-gel additive. See
Fuel Quality (page 106).
Note:The vehicle Warranty may be void if
you use additives that do not meet or
exceed Ford specifications. If the low fuel
pressure message persistently appears after
re-fueling and then disappears when the
engine has fully warmed up, consider using
different fuel sources.• Low fuel operation: If the low fuel
pressure message appears when your
vehicle is warm and during low fuel
tank level operation (near empty),
refuel your vehicle. If the message
reappears after fueling, see below. If
the message does not come back, the
low fuel pressure condition was due to
low fuel levels in the fuel tank.
• Normal operation: If the low fuel
pressure message appears during
normal operation when the engine is
fully warm, and fuel level is not low,
you must change the fuel filters
regardless of the maintenance
schedule interval.
• If replacement of the fuel filter does
not remedy the low fuel pressure
message during normal operation as
defined above, take the vehicle to an
authorized dealer.
FUEL QUALITY - DIESEL
Fuel Requirements - Choosing The
Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Required (United
States/Canada/Puerto Rico/U.S.
Virgin Islands And Other Locales)
You should use Ultra-Low Sulfur Diesel
fuel (also known as ULSD) designated as
number 1-D or 2-D with a maximum of
15-ppm sulfur in your diesel vehicle. You
may operate your vehicle on diesel fuels
containing up to 20% biodiesel, also
known as B20. These fuels should meet
the ASTM D975 diesel or the ASTM D7467
B6-B20 biodiesel industry specifications.
Outside of North America, use fuels
meeting EN590 or equivalent local market
standard.
Note:The vehicle Warranty does not cover
damage caused by using an improper type
of fuel or fuel additive.
106
Fuel and Refueling

Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
• Confirm the biodiesel content of the
fuel to be B20 (20% biodiesel) or less
• Only use biodiesel fuel of good quality
that complies with industry standards
• Follow the recommended service
maintenance intervals. See
Scheduled Maintenance (page 319).
• Do not store biodiesel fuel in the fuel
tank for more than 1 month
• Consider changing brands or reducing
biodiesel content if you have cold
temperature fuel gelling issues or a
frequent LOW FUEL PRESSURE
message appearing
• Do NOT use raw oils, fats or waste
cooking greases
Use of biodiesel in concentrations greater
than 20% may cause damage to your
vehicle, including engine and/or exhaust
after-treatment hardware (exhaust
catalyst and particulate filter) failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that may result
in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil is
recommended for fuels with greater than
5% biodiesel (B5). Refer to the Special
operating conditions section under the
Schedule Maintenance chapter for more
information about oil change intervals and
other maintenance when operating on
biodiesel.Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in a diesel fuel. Biodiesel content is often
indicated with the letter B followed by the
percent of biodiesel in the fuel. For
example, B20 indicates a fuel containing
20% biodiesel. Ask the service station
attendant to confirm the biodiesel content
of a diesel fuel if you do not see a label on
the fuel pump.
Biodiesel fuels degrade more easily than
diesel fuels not containing biodiesel and
should not be stored in the fuel tank for
more than 1 month. If you plan to park or
store your vehicle for more than 1 month,
then you should empty your vehicle fuel
tank of biodiesel fuel. You should fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle for a minimum of
30 minutes.
Note:Degraded or oxidized biodiesel can
damage fuel system seals and plastics and
corrode steel parts.
During cold weather, if you have problems
operating on biodiesel, you may need to
use a diesel fuel with lower biodiesel
content, try another brand, or discontinue
the use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add any
aftermarket additives to your fuel if you
use a high quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
injector system or engine.
Use Motorcraft® cetane booster or an
equivalent cetane booster additive if you
suspect fuel has low cetane. Use
Motorcraft® anti-gel & performance
improver or an equivalent additive if there
is fuel gelling.
108
Fuel and Refueling

• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note:Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note:If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire.
WARNING: The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off.
WARNING: Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle (page 190).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note:Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.
