2016 FORD F750 lock

If you have to add more than 1.0 quart (1.0
liter) of engine coolant per month, have
your authorized dealer check the engine
cooling system. Your cooling system may
have a leak. Operating an engine with a
low level of coolant can result in engine
overheating and possible engine damage.
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 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 COLD FILL
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 COLD
FILL 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).
Secondary cooling system: Repeat
Step 5 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).
11. Reinstall the pressure relief cap. Shut
the engine off and let it cool.
12. Check the coolant level in the reservoir before you drive your vehicle
the next few times (with the engine
cool).
13. If necessary, add prediluted engine coolant to the coolant reservoir until
the coolant level is within the COLD
FILL RANGE as listed on the reservoir.
After any coolant has been added,
check the coolant concentration. See
Adding Engine Coolant
earlier in
the chapter for more information.
Whenever coolant has been added, the
coolant level in the reservoir should be
checked the next few times you drive the
vehicle. If needed, add prediluted engine
coolant to bring the coolant level to the
proper level on the reservoir.
Recycled Engine Coolant
Ford Motor Company does not recommend
the use of recycled engine coolant since a
Ford-approved recycling process is not yet
available.

State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle
’s paint finish, wiper blades or
washer system.
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.

4.
Allow the engine to idle for at least one
minute.
5. Turn the air conditioning (if equipped) on and allow the engine to idle for at
least one minute.
6. Release the parking brake. With your foot on the brake pedal and with the
air conditioning on, put the vehicle in
drive (D) and allow the engine to idle
for at least one minute.
•If you do not allow the engine to
relearn its idle trim, the idle quality
of your vehicle may be adversely
affected until the idle trim is
eventually relearned.
7. Drive the vehicle to complete the relearning process
•The vehicle may need to be driven
10 mi (16 km) or more to relearn the
idle and fuel trim strategy along
with the ethanol content for flexible
fuel vehicles.
If the battery has been disconnected or a
new battery has been installed, the clock
and radio settings must be reset once the
battery is reconnected.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.
Battery Management System (If
Equipped)
The battery management system (BMS)
monitors battery conditions and takes
actions to extend battery life. If excessive
battery drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate
control fan, heated steering wheel, audio
and navigation system. A message may be shown in the information displays to alert
the driver that battery protection actions
are active. These messages are only for
notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
Electrical accessory installation
To ensure proper operation of the BMS,
any electrical devices that are added to
the vehicle should not have their ground
connection made directly at the negative
battery post. A connection at the negative
battery post can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
Note:
Electrical or electronic accessories
added to the vehicle by the dealer or the
owner may adversely affect battery
performance and durability, and may also
affect the performance of other electrical
systems in the vehicle.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
which matches the electrical requirements
of the vehicle. After battery replacement,
or in some cases after charging the battery
with the external charger, the BMS requires
eight hours of vehicle sleep time (key off
with doors closed) to relearn the new
battery state of charge. Prior to relearning
the state of charge, the BMS may disable
electrical features (to protect the battery)
earlier than normal.
