2022 FORD F-250 engine coolant

•
Make sure that when in operation, the
extension cord plug and engine block
heater cord plug connections are free
and clear of water. This could cause an
electric shock or fire.
• If the engine block heater cord is under
the hood, do not remove the wiring
from its original location. Do not close
the hood on the extension wiring.
• Park your vehicle in a clean area, clear
of combustible materials.
• Firmly connect the engine block heater
cord and the extension cord.
• Check the extension cord for heat
anywhere when the system has been
operating for approximately 30
minutes.
• Unplug and properly stow the system
before starting and driving your vehicle.
The protective cover seals the
terminals of the engine block heater
cord plug when not in use.
• Check the engine block heater system
for proper operation before winter.
HOW DOES THE ENGINE BLOCK
HEATER WORK
The engine block heater warms the engine
coolant. This allows the climate control
system to quickly respond. The equipment
includes a heater element installed in the
engine block and a wire harness. You can
connect the system to a grounded
220-240 volt AC electrical source.
Note: The engine block heater is most
effective when outdoor temperatures are
below 0°F (-18°C).
USING THE ENGINE BLOCK
HEATER
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary. The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the engine block heater longer than
three hours does not improve system
performance and unnecessarily uses
electricity.

Note:
Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel significantly
increases your vehicle ’s exhaust emissions
and reduce engine life due to increased
internal wear.
We recommend Top Tier diesel fuel where
available to help minimize engine deposits
and maintain optimal vehicle and engine
performance.
For additional information, visit
www .t op tier g a s. c om .
You should use ultra-low sulfur diesel fuel
designated as number 1-D or 2-D with a
maximum of 15-ppm sulfur in your diesel
vehicle. You can operate your vehicle on
diesel fuels containing up to 20%
biodiesel, also known as B20. These fuels
should meet the ASTM D975 diesel or the
ASTM D7467 B6-B20 biodiesel industry
specifications. Outside of North America,
use fuels meeting EN590 or equivalent
local market standard. Using low-sulfur diesel fuel
(16-500 ppm) or high-sulfur
diesel fuel (greater than 500
ppm) in your diesel engine will cause
certain emission components to
malfunction which could also cause the
service engine soon light to illuminate
indicating an emissions-related concern.
Diesel fuel is adjusted seasonally for cold
temperature. For best results at
temperatures below 19°F (-7°C), we
recommend using a diesel fuel which has
been seasonally adjusted for the ambient
conditions. Choosing the Right Fuel: Vehicles
Operated Where Ultra Low Sulfur
Diesel Fuel Is Not Required
For the engine to operate reliably on
low-sulfur or high-sulfur diesel fuel, the
engine must be a factory-built high-sulfur
engine (available as a dealer order option
for select markets) or an ultra-low sulfur
diesel fuel configured engine that has been
retrofitted for high-sulfur diesel fuel using
authorized dealer service parts. Failure to
use retrofit components other than those
available through your authorized dealer
results in coolant system damage, engine
overheating, selective catalyst reduction
system or diesel particulate filter damage
and possible base engine damage.
Use only a diesel engine configured for use
with high-sulfur diesel fuel in markets with
diesel fuel that has sulfur content greater
than 15 ppm. Using low-sulfur diesel fuel
(16–500 ppm) or high-sulfur diesel fuel
(greater than 500 ppm) in a diesel engine
designed to use only ultra-low sulfur diesel
fuel could result in damage to engine
emission control devices and the after
treatment system, potentially rendering
the vehicle inoperable.
Vehicles with engines configured for use
with high-sulfur diesel fuel are only
available for sale in countries where
ultra-low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in an ultra-low
sulfur diesel fuel market that are
subsequently exported to non-ultra low
sulfur diesel fuel markets will need to be
retrofitted at the customer
’s expense using
Ford authorized dealer service parts in
order to be reliably operated on non-ultra
low sulfur diesel fuel.

CHECKING THE COOLANT
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 622).
Note: Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29°F (-34°C) and -35°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 remove the
coolant reservoir cap when the engine is
on or 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 add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow
this instruction could result in personal
injury. WARNING:
Do not add coolant
further than the MAX mark. 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.
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.
Note: Automotive fluids are not
interchangeable.
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 467). 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 could
void the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with deionized or
distilled water. See
Capacities and
Specifications (page 467). Using water that
has not been deionized may contribute to
deposit formation, corrosion and plugging
of the small cooling system passageways.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add enough prediluted coolant to reach the correct level.
Note: We do not recommend the use of
recycled coolant.
402
2022 Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202103, First-Printing Maintenance

3.
Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
4. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, repeat step
2.
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.
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
Service your vehicle as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute, as they can cause engine
damage from overheating or freezing:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Severe Climates
If you drive in extremely cold climates, you
may need to increase the coolant
concentration above 50%.
Note: A coolant concentration of 60%
provides improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and could
cause engine damage. If you drive in extremely hot climates, you
may need to decrease the coolant
concentration to 40%.
Note:
A coolant concentration of 40%
provides improved overheat protection.
Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the coolant and
could cause engine damage.
Coolant Change
Change the coolant at specific mileage
intervals. Refer to the scheduled
maintenance information. See
Normal
Scheduled Maintenance (page 628).
Note: Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.

When this occurs, your vehicle still
operates, however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or 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.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine could operate poorly. Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait for a short period of time for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management
(If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
