CHANGING THE ENGINE OIL
AND OIL FILTER WARNINGS
Do not handle a hot oil filter with
bare hands.
Continuous contact with used motor
oil has caused cancer in laboratory
mice. Protect your skin by washing
with soap and water. If your vehicle is equipped with a diesel
engine, an Intelligent Oil Life Monitor™
calculates the proper oil change service
interval. When the information display
indicates: OIL CHANGE REQUIRED, change
the engine oil and oil filter. See
Information Displays
(page 62).
The engine oil filter protects your engine
by filtering harmful, abrasive or sludge
particles and particles significantly smaller
than most available will-fit filters. See
Motorcraft Parts
(page 254).

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
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
Capacities and Specifications (page 258).
Using water that has not been deionised
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
Capacities and
Specifications (page 258).
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 additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community ’s regulations and standards
for recycling and disposing of automotive
fluids.
191
F-650/750 (TBC) , enUSA, First Printing Maintenance

Adding Coolant
WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
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 Capacities and
Specifications (page 258). 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 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
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
Capacities and Specifications (page 258).
Using water that has not been deionised
may contribute to deposit formation,

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 while the pressure releases.
4. When you are sure that all the pressure
has been released, use the cloth to turn
it counterclockwise and remove the
cap.
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
Step 5 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).

DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL
Your vehicle is equipped with a diesel fuel
conditioner module located on the
frame-rail under the driver-side floorboard
near the transmission.
You should drain water from the
module assembly whenever the
warning light comes on and the
message center directs you to drain the
water separator. This will occur when
approximately 8.45 fl oz (250 ml) of water
accumulates in the module. If you allow
the water level to exceed this level, the
water may pass through to the engine and
may cause fuel injection equipment
damage.
Draining the Diesel Fuel
Conditioner Module (DFCM) WARNING
Your vehicle must be stopped with
the engine off when draining the
Diesel Fuel Conditioner Module. Fuel
may ignite if the separator is drained while
the engine is running or vehicle is moving. Note:
If you drain the diesel fuel conditioner
module while the system is running air will
enter into the fuel system. The engine will
not operate properly if air enters the system.
Note: With fuel tank levels above 3⁄4 tank
it may be necessary to loosen the bowl three
turns before opening the drain. This will
actuate an anti-siphon valve at the fuel and
water separator inlet and prevent the fuel
from siphoning out of the tank.
Note: A loose drain valve can allow air to
enter the fuel system and cause drivetrain
issues. The engine will not operate properly.
Be sure that you fully tighten the drain valve. 1. Stop your vehicle and shut off the
engine.
2. Locate the diesel fuel conditioner module and place an appropriate
container under the drain port. 3.
Rotate the drain counterclockwise until
the O-ring is visible. Allow the diesel
fuel conditioner module to drain for
approximately 25 seconds or until
clean fuel is observed. Rotate the drain
clockwise to tighten it. If no liquid
drains, there may be a clog in the drain.
Have the conditioner module serviced
by an authorized dealer.
4. Make sure that you fully tighten the drain valve and then remove the
container from under your vehicle.
5. Restart the engine. If the WATER IN FUEL DRAIN FILTER or WATER IN FUEL
DRAIN FILTER SEE MANUAL message
and light continues to illuminate, have
the fuel system checked and repaired.
FUEL FILTER - 6.8L
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.
