2017 FORD F750 service

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 316).
• 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.
94
F-650/750 (TBC) , enUSA, First Printing Fuel and Refueling

Do not use alcohol-based additives to
improve cetane quality, to prevent fuel
gelling or any other use. The use of alcohol
additives may result in damage to the fuel
injectors and system. See Capacities and
Specifications (page 263).
The Vehicle Warranty may not cover
repairs needed to correct the effects of
using an aftermarket product that does
not meet Ford specifications in your fuel.
RUNNING OUT OF FUEL -
GASOLINE
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you run out of fuel:
• You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal. With keyless ignition, just start
the engine. Crank time will be longer
than usual.
• Normally, adding 1 gal (3.8 L) of fuel is
enough to restart the engine. If the
vehicle is out of fuel and on a steep
grade, more than
1 gal (3.8 L) may be
required.
• The service engine soon indicator may
come on. See
Warning Lamps and
Indicators (page 58).
RUNNING OUT OF FUEL -
DIESEL
Avoid running out of fuel. This allows air to
enter the fuel system and may make it
difficult to restart your vehicle. If your vehicle runs out of fuel:
•
Normally adding
4–5 gal (15– 19 L) of
fuel is enough to restart the engine. If
your vehicle is out of fuel and on a
steep grade, more than
5 gal (19 L)
may be required.
• You must purge trapped air from the
system before restarting the engine.
Purging Air From the System
Switch the ignition on for 30 seconds and
then switch the ignition off. Repeat this
operation six times in a row to purge any
trapped air from the fuel system.
Any remaining air in the system self-purges
when the engine starts. The engine may
run rough or produce white smoke when
air remains in the fuel system. This is
normal and stops after a short period. If
the engine continues to run rough, have
your vehicle checked as soon as possible.
Starting the Engine
Do not crank the engine for more than 10
seconds as starter damage may occur. If
the engine fails to start, switch the ignition
off and wait 30 seconds before cranking
the engine again. See
Starting a Diesel
Engine (page 86).
SELECTIVE CATALYTIC
REDUCTION SYSTEM - DIESEL
Your vehicle may have a selective catalytic
reduction system. The system helps reduce
emission levels of oxides of nitrogen from
the exhaust system. The system
automatically injects diesel exhaust fluid
into the exhaust system to enable correct
selective catalytic reduction system
function.
Note: Selective catalytic reduction systems
are not fitted to vehicles in markets where
only high-sulfur diesel fuel is available.

F-650/750 (TBC) , enUSA, First Printing Fuel and Refueling

Note:
For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you repair the contaminated system.
To service a contaminated or inoperative
system, see an authorized dealer.
REFUELING - GASOLINE WARNINGS
Fuel vapor burns violently and a fuel
fire can cause severe injuries.
Read and follow all the instructions
on the pump island.
When refueling always shut the
engine off and never allow sparks or
open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. Stay outside your vehicle and do not
leave the fuel pump unattended
when refueling your vehicle.
Keep children away from the fuel
pump; never let children pump fuel.
Wait at least 10 seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into
the fuel tank. Stop refueling after the fuel pump
nozzle automatically shuts off for the
second time. Failure to follow this
will fill the expansion space in the fuel tank
and could lead to fuel overflowing. Do not remove the fuel pump nozzle
from its fully inserted position when
refueling. Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
•
Place approved fuel container on the
ground.
• Do not fill a fuel container while it is in
the vehicle (including the cargo area).
• Keep the fuel pump nozzle in contact
with the fuel container while filling.
• Do not use a device that would hold
the fuel pump handle in the fill position.
Fuel Filler Cap WARNINGS
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury. If you do not use the correct fuel filler
cap, excessive pressure or vacuum
in the fuel tank may damage the fuel
system or cause the fuel cap to disengage
in a crash. Failure to follow this warning
could result in serious personal injury. The fuel tank has a threaded fuel filler cap.
Note:
If you must replace the fuel filler cap,
replace it with a fuel filler cap that is
designed for your vehicle. The vehicle
Warranty may be void for any damage to
the fuel tank or fuel system if the correct
genuine Ford, Motorcraft or other certified
fuel filler cap is not used.
When refueling the vehicle fuel tank do the
following.
1. When your vehicle has stopped, shift into neutral (N) or park (P).
2. Apply the parking brake and switch the
ignition off.
3. Turn the fuel filler cap counterclockwise and remove it.

F-650/750 (TBC) , enUSA, First Printing Fuel and Refueling

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.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:
1. Your vehicle has run out of fuel —the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Refueling (page 100).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.

Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.
If the vehicle ’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.
EMISSION CONTROL SYSTEM
- DIESEL
Oxidation Catalytic Converter and
Diesel Particulate Filter System (If
Equipped) 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 diesel oxidation
catalytic converter or the diesel particulate
filter. The diesel oxidation catalytic
converter and the diesel particulate filter
heat up to very high temperatures after
only a short period of engine operation and
remain hot after you switch the engine off. Your vehicle has a diesel particulate filter.
The diesel particulate filter is an inline filter
in the exhaust system that reduces carbon
emissions by trapping exhaust particles
before they reach the tailpipe. The diesel
particulate filter looks similar to a
traditional exhaust catalyst and is part of
the exhaust system under your vehicle. The
105
F-650/750 (TBC) , enUSA, First Printing Fuel and Refueling

Note:
You cannot use the operator
commanded regeneration until the diesel
particulate filter load percentage has
reached 100%. The diesel particulate filter
load percentage fluctuates up and down
when driving your vehicle due to active and
passive regenerations.
Note: During the use of operator
commanded regeneration, you may observe
a light amount of white smoke. This is
normal. You may not be able to use
operator commanded
regeneration if the service engine
soon warning lamp appears in the
information display
Information Display Procedure
Start with your vehicle engine and when it
has reached the normal operating
temperature, press the information display
control button on the steering wheel. See
Information Display Control (page 45).
If a message advising that the exhaust
filter is full appears in the information
display, press the OK button to set the
display to Y. Answer yes to this prompt
and then follow the next prompts
regarding exhaust position required 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.
If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See
Information Messages
(page 64).
Answer yes to this prompt and then follow
the next prompts regarding exhaust
position required 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. When the system is at the point
of oversaturation, the service
engine warning lamp illuminates
and a message appears in the information
display. You cannot initiate filter cleaning.
You must have your vehicle checked as
soon as possible.
Once operator commanded regeneration
starts, engine speed increases to
approximately 2000– 2500 rpm and the
cooling fan speed increases. You will hear
a change in audible sound due to engine
speed and cooling fan speed increases.
It is not necessary to open the hood on the
engine compartment. Once operator
commanded regeneration completes, the
engine speed 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
108
F-650/750 (TBC) , enUSA, First Printing Fuel and Refueling

filter system. You can switch off automatic
regeneration until better driving conditions
are available, for example steady high
speed driving. You can then switch
automatic regeneration back on to clean
the diesel particulate filter.
Switching Automatic Regeneration
Control On and Off
To switch operator commanded
regeneration on and off, use the
information display control on the steering
wheel. See Information Display Control
(page 45). Scroll to the exhaust cleaning
message and then select Y or N to switch
it On or Off.
How to Interrupt or Cancel Operator
Commanded Regeneration
If you need to cancel the operator
commanded regeneration, pressing the
brake, accelerator or switching the engine
off stops the procedure. Depending on the
amount of time you allowed the operator
commanded regeneration to operate, soot
may not have had sufficient time to be fully
eliminated, but the exhaust system and
exhaust gas may still be hot. If you shut
your vehicle off during operator
commanded regeneration, you may notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal.
Filter Service and Maintenance
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be removed
for ash cleaning at approximately
120,000 mi (190,000 km)
or it may need
to be replaced with a new or
remanufactured part. Actual mileage
varies depending on engine and vehicle operating conditions. The filter may need
to be replaced with a new or
remanufactured part at approximately
250,000 mi (400,000 km)
. Actual
mileage varies depending on engine and
vehicle operating conditions. If filter service is required, the
engine control system warning
lamp illuminates in the
information display. If there are any issues with the
diesel particulate filter system,
the engine control system
warning lamp and a service
engine soon warning lamp
illuminate to inform you that
your vehicle requires service. Have your
vehicle checked as soon as possible.
Resonator and Tailpipe Assembly
Maintenance
Aftermarket devices or modifications to
the exhaust system may reduce the
effectiveness of the exhaust system as
well as cause damage to the exhaust
system or engine. This may also degrade
vehicle performance and could lead to
engine damage that may not be covered
by the vehicle Warranty.
Emission Control System Laws WARNING
Do not remove or alter the original
equipment floor covering or
insulation between it and the metal
floor of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal
floor. Failure to follow these instructions
may result in fire or personal injury. 109
F-650/750 (TBC) , enUSA, First Printing Fuel and Refueling

In the United States, federal law and
certain state laws prohibit removing or
rendering the emission control system
inoperative. Similar federal or provincial
laws may apply in Canada. We do not
recommend any vehicle modification
without determining applicable law.
Tampering with emissions
control system, including related
sensors or the diesel exhaust
fluid injection system can result in reduced
engine power and the service engine soon
warning lamp illuminating in the
information display.
Tampering with a Noise Control
System
Federal law prohibits the following acts or
the causing thereof:
• The removal or rendering inoperative
by any person other than for purposes
of maintenance, repair or replacement
of any device or element of design
incorporated into any new vehicle for
the purpose of noise control prior to its
sale or delivery to the ultimate
purchaser or while it is in use.
• The use of the vehicle after such device
or element of design has been removed
or rendered inoperative by any person.
Among those acts, which the United States
Environmental Protection Agency may
presume to constitute tampering are the
acts listed below:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer ’s
specifications. The complexity of the diesel engine makes
it so the owner is discouraged from
attempting to perform maintenance other
than the services described in this Owner's
Manual.
If you experience difficulty starting the
engine, rough idling, excessive exhaust
smoke, a decrease in engine performance
or excess fuel consumption, perform the
following checks:
•
A plugged or disconnected air inlet
system or engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Check engine oil level.
• Wrong fuel or oil viscosity for the
climatic conditions.
If these checks do not help you correct the
engine performance problem you are
experiencing, have your vehicle checked
as soon as possible.
