Diesel Lubrication System
It is important to change the engine oil at
the recommended service intervals or
when indicated by the information display
to maintain oil viscosity. Extending the oil
and filter change interval beyond the
recommended interval can negatively
affect engine performance, fuel economy
and engine life. See Engine Oil Check
(page 186).
Engine and secondary cooling system
The cooling system contains a primary
cooling loop to cool the engine and a
secondary cooling loop to cool the
transmission, charge air, and fuel. The
coolant serves three primary purposes: to
provide heat transfer, freeze point
protection, and corrosion protection using
additives.
Vehicles with diesel engines typically are
used to carry heavy loads and accumulate
mileage rapidly. These two factors may
cause the additives in the coolant to wear
out in a shorter time. You can find more
information about coolant additives and
coolant change intervals in the coolant
chapter. See
General Maintenance
Information (page 314). Operating the
engine with insufficient coolant or coolant
additive can cause severe engine damage. Selective catalytic reduction system
Your vehicle is equipped with a selective
catalytic reduction system designed to
reduce emission levels of nitrogen oxides
from the exhaust of your diesel engine. This
system relies on the use of Diesel Exhaust
Fluid (DEF) that you must replenish at
certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes
contaminated will result in vehicle speed
limitations or result in your vehicle entering
an idle-only mode. See
Selective
Catalytic Reduction System (page 95).
Minor Troubleshooting Guide
If the engine won ’t crank WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to the start position, the lights
become dim or go out, the battery
connections may be loose or corroded, or
the battery may be discharged. If there is
a clicking or stuttering sound coming from
the engine compartment when you turn
the key to the start position, this may also
indicate a loose or corroded battery
connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.

•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, See
Jump Starting the Vehicle (page 153).
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump.
• Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive •
Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter
If fuses burn out WARNING
Replacement fuses and circuit
breakers must always be the same
rating as the original equipment
shown. Never replace a fuse or circuit
breaker with one of a higher rating. Higher
rated fuses or circuit breakers could allow
circuit overloading in the event of a circuit
malfunction, resulting in severe vehicle
damage or personal injury due to fire. Burned-out or blown fuses usually indicate
an electrical short-circuit, although a fuse
may occasionally burn out from vibration.
Insert a second fuse. If this fuse
immediately burns out and you cannot
locate the cause, return your vehicle to
your dealer for a circuit check. See
Changing a Fuse
(page 170).
Selective catalytic reduction system
speed limit and Idle-only modes
If the vehicle ’s speed is limited or in an
idle-only mode, the selective catalytic
reduction system may be limiting the
vehicle ’s functions due to low or
contaminated DEF. Check the DEF. See
Selective Catalytic Reduction System
(page
95).

PROTECTING THE
ENVIRONMENT
You must play your part in protecting the
environment. Correct vehicle usage and
the authorized disposal of waste, cleaning
and lubrication materials are significant
steps toward this aim.
NOISE POLLUTION CONTROL
In order to keep to the federal exterior
noise regulations, your vehicle may be
equipped with noise emission items.
Depending on your vehicle configuration,
it may have all or some of the following
items:
Air Intake System
Inspect the air cleaner. Do not alter its
location. Do not alter inlet and outlet
piping.
Body
Inspect wheel well splash shields, cab
shields and under hood insulation for
deterioration, dislocation and orientation.
Cooling System
•
Inspect the fan for blade damage. If
you find any damage, replace with the
recommended parts. Inspect for
fan-to-shroud interference and any
damage to shroud, such as cracks and
holes.
• Do not change fan ratio or alter fan
spacer dimensions and positions.
• Inspect fan clutch for proper operation.
Make sure the fan is disengaged when
cooling of the engine is not required.
• Inspect radiator shutters (if equipped)
for proper operation. The shutters
should be open during normal
operating temperatures. Engine
Valve covers and block covers damp-out
engine mechanical noise. If they need
replacing, make sure to replace them with
the recommended parts. Check for
mechanical isolations.
Transmission Enclosure
Inspect for cracks, holes and tears. Clean
any deposits, such as oil, dirt and stones.
Exhaust System
•
Inspect for leaks at various joint
connections and loose clamps.
• Perform a visual inspection for cracks
or holes in the muffler and tail pipe.
• Always use the recommended
replacement parts.
• Do not change the tail pipe elbow or
offset tail pipe orientation from the
standard position as originally received.
• To avoid abnormal changes in vehicle
sound levels, it is necessary for the
owner to perform inspections and
necessary maintenance at specified
intervals. See Scheduled
Maintenance (page 314).

If the diesel particulate filter is near or at saturation, a message requesting
permission to initiate filter cleaning appears in the information display:
Action and Description
Message
Answer yes to this prompt and then follow the prompts
regarding exhaust position as needed to initiate Operator
Commanded Regeneration. Be sure to understand each
prompt. If you are not sure what is being asked by each
prompt, contact an authorized dealer. The display confirms
the operation has started and when it has finished. You can
also drive to clean the filter. See Active regeneration earlier
in this chapter.
Exhaust Filter Full Clean
Soon When the system is at the point
of oversaturation, the service
engine soon light illuminates.
The following message appears in the information display: Action and Description
Message
You cannot initiate cleaning. You must have your vehicle
serviced by an authorized dealer.
Exhaust filter over limit
Service now
Once Operator Commanded Regeneration
starts, the engine ’s rpm raises to
approximately 2000 rpm and the cooling
fan speed increases; you will hear a change
in audible sound due to the fan and engine
speed increase.
It is not necessary to open the hood on the
engine compartment. Once Operator
Commanded Regeneration is complete,
the engine rpm and fan returns to normal
idling. The exhaust system remains very
hot for several minutes even after
regeneration is complete. Do not reposition
the vehicle over materials that could burn
until the exhaust system has had sufficient
time to cool. Depending on the amount of
soot collected by the diesel particulate
filter, ambient temperature, and altitude,
Operator Commanded Regeneration lasts
approximately 30 minutes. Operator Commanded Regeneration
with Automatic Regeneration Control
(If Equipped)
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system. You can switch off automatic
regeneration until better driving conditions
are available, for example steady high
driving. You can then switch automatic
regeneration back on to clean the diesel
particulate filter.

9. Start your vehicle.
Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as you rotate the halves together.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute or damage to the
transmission and tires may occur, or the
engine may overheat.
If your vehicle is stuck in mud or snow, you
may rock it out by shifting between forward
and reverse gears, stopping between shifts
in a steady pattern. Press lightly on the
accelerator in each gear.
POWER TAKE-OFF
Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the vehicle is stationary or mobile. In the
stationary condition, there is limited
cooling air flow through the radiator and
around the vehicle that normally occurs
when a vehicle is moving. The aftermarket
PTO system installer, having the most
knowledge of the final application, is
responsible for determining whether
additional chassis heat protection or
powertrain cooling is required and alerting
the user to the safe and proper operation.
Your vehicle is approved for use as a
Stationary Mode, SplitShaft Mode or
Mobile Mode power source within the limits
and operating guidelines detailed in the
Ford Truck Body Builders Layout Book,
found at
www.fleet.ford.com/truckbbas.com and
through the Ford Truck Body Builders
Advisory Service. The transmission power
source modes are engine specific.

ESSENTIAL TOWING CHECKS
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% of the total weight of the
trailer is on the tongue.
Safety Chains
Note: Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle
hitch.
To connect the safety chains, cross the
chains under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Trailer Brakes WARNING
Do not connect a trailer's hydraulic
brake system directly to your
vehicle's brake system. Your vehicle
may not have enough braking power and
your chances of having a collision greatly
increase. Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations. The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Trailer Lamps
WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required. Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 miles (80
kilometers).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position
P or position N to
aid engine and transmission cooling
and to help air conditioning
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
