2016 FORD F750 heating

You have limited engine power when in the
fail-safe mode, so drive the vehicle with
caution. The vehicle will not be able to
maintain high-speed operation and the
engine will run rough. Remember that the
engine is capable of completely shutting
down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely
possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without repairing
the engine problem increases the chance of
engine damage. Take your vehicle to an
authorized dealer as soon as possible.
Engine Fluid Temperature
Management (If Equipped) WARNINGS
To reduce the risk of collision and
injury, be prepared that the vehicle
speed may reduce and the vehicle
may not be able to accelerate with full
power until the fluid temperatures reduce. Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle has been designed to pull a
trailer, but because of the added load, the
vehicle
’s engine may temporarily reach
higher temperatures during severe
operating conditions such as ascending a
long or steep grade while pulling a trailer
in hot ambient temperatures. At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP message may appear
in the information display.
You may notice a reduction in the vehicle
’s
speed caused by reduced engine power.
In order to manage the engine fluid
temperatures, your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction will depend on
the vehicle loading, towing, grade, ambient
temperature, and other factors. If this
occurs, there is no need to pull off the road.
The vehicle can continue to be driven while
this message is active.
The air conditioning may turn on and off
during severe operating conditions to
protect the engine from overheating. When
the engine coolant temperature decreases
to a more normal operating temperature,
the air conditioning will turn on once again.
If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Stop your vehicle as soon as safely possible and shift the transmission into
Park (P).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After
several minutes, if this does not
happen, follow the remaining steps.
3. Switch the engine off and wait for it to
cool before checking the coolant level.
4. If the coolant level is normal, you may restart your engine and continue on.

5. If the coolant is low, add coolant,
restart the engine and take your vehicle
to an authorized dealer. See Adding
engine coolant in this chapter for more
information. Refer to fail-safe cooling
for additional information.
ENGINE COOLANT CHECK -
6.7L DIESEL WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield. 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. Do not add coolant further than the
MAX mark.
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information. See
Scheduled Maintenance
(page 314).
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. The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between
-30°F
(-34.5°C) and -34°F (-36.5°C).
Note: For best results, coolant
concentration should be tested with a
refractometer such as Robinair® Coolant
and Battery Refractometer 75240. We do
not recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Engine Coolant
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. This damage
would not be covered under your vehicle ’s
warranty.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red. As long as the
engine coolant is clear and uncontaminated,
this color change does not indicate the
engine coolant has degraded nor does it
require the engine coolant to be drained, the
system to be flushed, or the engine coolant
to be replaced.

•
Do not mix different colors or types of
coolant in your vehicle. Make sure the
correct coolant is used. Mixing of
engine coolants may harm your
engine ’s cooling system. The use of an
improper coolant may harm engine and
cooling system components and may
void the warranty. Use prediluted
engine coolant meeting the Ford
specification. See Capacities and
Specifications (page 251).
• In case of emergency, a large amount
of water without engine coolant may
be added in order to reach a vehicle
service location. In this instance, the
cooling system must be drained,
chemically cleaned with Motorcraft
Premium Cooling System Flush, and
refilled with engine coolant as soon as
possible. Water alone (without engine
coolant) can cause engine damage
from corrosion, overheating or freezing.
• Do not use alcohol, methanol, brine or
any engine coolants mixed with alcohol
or methanol antifreeze (coolant).
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 engine coolant.
Add prediluted engine coolant meeting the
Ford specification (Motorcraft Orange
Antifreeze/Coolant Prediluted). See
Capacities and Specifications
(page
251).
Note: Generic coolants marketed for all
makes and models may not meet the Ford
specification and may cause damage to the
cooling system. This damage may void the
warranty. 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 engine coolant
(Motorcraft Orange Antifreeze/Coolant
Prediluted) to the FULL COLD level. For all
other 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 of a vehicle with
an overflow system, follow these steps to
add engine coolant.
1. Turn the engine off and let it cool.
2. When the engine is cool, wrap a thick
cloth around the coolant pressure relief
cap on the coolant reservoir (a
translucent plastic bottle). Slowly turn
cap counterclockwise until pressure
begins to release. When you are sure
that all the pressure has been released,
use the cloth to turn it
counterclockwise and remove the cap.
3. Fill the coolant reservoir slowly with prediluted engine coolant to within the
FULL COLD level, or between the MIN
and MAX marks (within the COLD FILL
RANGE), as listed on the engine
coolant reservoir. If you removed the
radiator cap in an overflow system, fill
the radiator until the coolant is visible
and radiator is almost full. If coolant is
added to bring the level within the
COLD FILL RANGE when the engine is
not cold, the system may remain under
filled.
4. Replace the cap. Turn until tightly installed. Cap must be tightly installed
to prevent coolant loss.
Whenever coolant has been added, the
coolant level in the coolant reservoir
should be checked the next few times you
drive the vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the proper level.
196
F650750 (TBC), enUSA, First Printing Maintenance

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.

F650750 (TBC), enUSA, First Printing Maintenance

Check the fluid at the normal operating
temperature of 196°F (91°C) to 215°F
(102°C) on a level surface. The normal
operating temperature can be reached
after approximately
20 mi (30 km).
High Fluid Level Fluid levels above the safe range may
result in transmission failure. An overfill
condition of transmission fluid may cause
shift and engagement concerns, and
possible damage.
High fluid levels can be caused by an
overheating condition.
Adjusting Automatic Transmission
Fluid Levels
Note:
Use of a non-approved automatic
transmission fluid may cause internal
transmission component damage.
Before adding any fluid, make sure the
correct type is used. The type of fluid used
is normally indicated on:
• the dipstick handle.
• See
Capacities and Specifications
(page 256).
If necessary, add fluid in
8 fl oz (250 ml)
increments through the filler tube until the
level is correct. If an overfill occurs, excess fluid should be
removed by a qualified technician.
Note:
An overfill condition of transmission
fluid may cause shift and engagement
concerns, and possible damage.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
BRAKE FLUID CHECK WARNINGS
Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death. Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with
plenty of water and contact your physician.

All Vehicles
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.
Ford Motor Company has recommended
maintenance intervals for various parts
and component systems based upon
engineering testing. Ford Motor Company
relies upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle. Additives and Chemicals
This owner's manual and the Ford
Workshop Manual list the recommended
additives and chemicals for your vehicle.
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle ’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using a Ford-approved flushing
chemical.
Emissions Control System WARNING
Because of high engine
compartment and exhaust system
temperatures resulting from
emissions equipment, do not park, idle or
operate your vehicle in dry grass or other
dry ground cover where the possibility of
ground fire exists. 315
