2023 FORD F650/750 clock

WARNING: Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank.
WARNING: 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.
WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling.
An engine that suddenly becomes noisy or
operates poorly after a fuel fill could be
using substandard fuel. We recommend
that you purchase diesel fuel from a
reputable fuel station.
Use only clean, approved containers that
prevent the entry of dirt or water whenever
you store diesel fuel.
Do not store diesel fuel in a galvanized
container. The fuel dissolves the zinc in the
galvanized container. The zinc will then
remain in the fuel. If you run the
contaminated fuel through the engine, the
zinc damages the fuel injectors. Engine
damage caused may not be covered by
the vehicle warranty.
Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
• Place the 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 when filling.
• Do not use a device that would hold
the fuel pump handle in the fill position.
Fuel Filler Cap
WARNING: 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.
Note: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.
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. Bring your vehicle to a complete stop
and 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.
4. Refuel your vehicle as required.
5. Replace the fuel filler cap, turn it
clockwise until you feel a strong
resistance.
Fuel Fill Rate
Your vehicle has a fuel fill pipe that is able
to accept fuel up to 20 gal (75 L) per
minute from a fuel-dispensing nozzle.
Pumping fuel at greater flow rates may
result in premature nozzle shut off or spit
back.
111
Fuel and Refueling

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.
4. Refuel your vehicle as required.
5. Replace the fuel filler cap, turn it
clockwise until you feel a strong
resistance.
If the fuel cap warning lamp or a warning
message appears in the instrument cluster,
you may not have installed the fuel filler
cap correctly.
If the fuel cap warning lamp remains on,
at the next opportunity, safely pull off of
the road, remove the fuel filler cap, align
the cap properly and reinstall it. The check
fuel cap warning lamp or warning message
may not reset immediately. It may take
several driving cycles for the indicators to
turn off. A driving cycle consists of an
engine start-up (after four or more hours
with the engine off) followed by normal
city and highway driving.
FUEL CONSUMPTION
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank after running out of fuel. Included in
the advertised capacity is an empty
reserve. The empty reserve is an
unspecified amount of fuel that remains
in the fuel tank when the fuel gauge
indicates empty.
Note:The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Filling the Fuel Tank
For consistent results when refueling:
• Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1,000 mi (1,600 km) of driving (this is
your engine’s break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km) to 3,000 mi
(4,800 km). Also, fuel expense, frequency
of fill ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the fuel tank, record
the amount of fuel added.
3. After at least three fill ups, fill the fuel
tank and record the current odometer
reading.
4. Subtract your initial odometer reading
from the current odometer reading.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per
gallon) fuel consumption, divide miles
traveled by gallons used.
113
Fuel and Refueling

Do not use supplemental engine oil
additives because they are unnecessary

ENGINE COOLANT CHECK -
6.7L DIESEL
WARNING: Do not remove the
coolant reservoir cap when 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.
WARNING: Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield.
WARNING: To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly.
WARNING: Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 319).
Note:Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant
WARNING: Do not add engine
coolant when the engine is hot. Failure
to follow this instruction could result in
personal injury.
WARNING: Do not remove the
coolant reservoir cap when 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.
Note: Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
233
Maintenance

Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See Cooling System Capacity
and Specification (page 297). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and may
not be covered by the vehicle Warranty.
Note: Coolants marketed for all makes and
models may not be approved to Ford
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
For vehicles with overflow coolant systems
with a non-pressurized cap on the coolant
recovery system, add coolant to the
coolant recovery reservoir when the engine
is cool. Add prediluted coolant to the
maximum level. For all vehicles which have
a coolant degas system with a pressurized
cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator,
follow these steps to add engine coolant:
1. Turn the engine off and let it cool.
2. Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.
3. Fill the coolant reservoir slowly with
prediluted engine coolant to within the
minimum and maximum range on the
engine coolant reservoir. If you
removed the radiator cap in an
overflow system, fill the radiator untilthe coolant is visible and the radiator
is almost full. If coolant is added to
bring the level within the minimum and
maximum range when the engine is not
cold, the system may remain under
filled.
4. Replace the coolant reservoir cap, turn
it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant
reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the proper level.
Note:If prediluted coolant is not available,
use the approved antifreeze concentrate
diluting it to 50/50 with distilled water. See
Cooling System Capacity and
Specification (page 297). Using water that
has not been deionized may contribute to
deposit formation, corrosion or plugging of
the small cooling system passageways.
If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.
Note:During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
In case of emergency, you can add a large
amount of water without prediluted
coolant in order to reach a vehicle service
location. On arrival do the following:
1. Drain the cooling system.
2. Chemically clean the cooling system.
We recommend Motorcraft Premium
Cooling System Flush.
234
Maintenance

3. Refill with prediluted coolant as soon
as possible.
Water alone, without prediluted coolant,
can cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or non-specified
additives to the coolant. These can be
harmful and compromise the corrosion
protection of the coolant.
Engine and Secondary Cooling
System Refill Procedure
The following procedure should be used
when refilling the engine or secondary
cooling systems after it has been drained
or become extremely low:
1. Before you remove the cap, turn the
engine off and let it cool.
2. When the engine is cool, wrap a thick
cloth around the cap. Slowly turn cap
counterclockwise until pressure begins
to release.
3. Step back when the pressure releases.
4. When you are sure that all the pressure
has been released, use the cloth to turn
the cap counterclockwise and then
remove it.
5. Slowly add prediluted engine coolant
to the coolant reservoir until the
coolant level is within the minimum
and maximum range as listed on the
reservoir.
6. Reinstall the pressure relief cap.7. Start and run the engine at 2000 rpm
for 2 minutes.
8. Shut engine off, and remove the
pressure relief cap as previously
outlined.
9. If required, add prediluted engine
coolant to the coolant reservoir until
the coolant level is within the minimum
and maximum range as listed on the
reservoir.
10. Engine cooling system: Repeat steps
5 through 9 until the coolant level has
stabilized (is no longer dropping after
each step) and the upper radiator
hose at the radiator is warm to the
touch (indicating that the engine
thermostat is open and coolant is
flowing through the radiator).
11. Check the secondary cooling system.
Repeat steps 1 through 10 until the
coolant level has stabilized (is no
longer dropping after each step) and
the lower passenger side of the
secondary radiator is warm to the
touch (indicating secondary
thermostat is open and coolant is
flowing through the entire system).
12. Check the coolant level in both
systems before you drive your vehicle
the next few times.
13. If necessary, add prediluted engine
coolant to the coolant reservoirs until
the coolant level is within the
minimum and maximum range as
listed on the reservoir. After any
coolant has been added, check the
coolant concentration.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
235
Maintenance

It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See Cooling System Capacity
and Specification (page 298). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and may
not be covered by the vehicle Warranty.
Note: Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
For vehicles with overflow coolant systems
with a non-pressurized cap on the coolant
recovery system, add coolant to the
coolant recovery reservoir when the engine
is cool. Add prediluted coolant to the
maximum level. For all vehicles which have
a coolant degas system with a pressurized
cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator,
follow these steps to add engine coolant:
1. Turn the engine off and let it cool.
2. Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.
3. Fill the coolant reservoir slowly with
prediluted engine coolant to within the
minimum and maximum range on the
engine coolant reservoir. If you
removed the radiator cap in an
overflow system, fill the radiator until
the coolant is visible and the radiator
is almost full. If coolant is added to
bring the level within the minimum and
maximum range when the engine is not
cold, the system may remain
underfilled.4. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant
reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the proper level.
Note:If prediluted coolant is not available,
use the approved antifreeze concentrate
diluting it to 50/50 with distilled water. See
Cooling System Capacity and
Specification (page 298). Using water that
has not been deionized may contribute to
deposit formation, corrosion or plugging of
the small cooling system passageways.
If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.
Note:During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
Note:In case of emergency, you can add a
large amount of water without coolant in
order to reach a vehicle service location.
Water alone, without coolant, can cause
engine damage from corrosion, overheating
or freezing. When you reach a service
location, you must have the cooling system
drained, flushed and refilled using the
correct specification prediluted coolant or
antifreeze concentrate. See Cooling
System Capacity and Specification (page
298).
