2020 FORD F-250 cooling

Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range
(between L and H). If the needle falls
below the normal range, stop your vehicle,
turn off the engine and check the engine
oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked by an
authorized dealer.
Engine Coolant Temperature
Gauge
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.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator will be in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
safely possible, switch off the engine and
let the engine cool.
Fuel Gauge
Note: The fuel gauge may vary slightly
when your vehicle is moving or on a slope.
The fuel gauge indicates about how much
fuel is in the fuel tank.
The arrow adjacent to the fuel pump
symbol indicates on which side of your
vehicle the fuel filler door is located. Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty
reaches
75 mi (120 km) to empty for
MyKey, and at 50 mi (80 km), 25 mi
(40 km), 10 mi (20 km) and 0 mi (0 km)
for all vehicle keys.
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Transmission Fluid Temperature
Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator will be in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grill. Also,
higher than normal operating temperature
can be caused by special operation
conditions (i.e. snowplowing, towing or
off-road use). Operating the transmission
for extended periods with the gauge in the
higher than normal area may cause
internal transmission damage. You need
to alter the severity of your driving
conditions to lower the transmission
temperature into the normal range. If the
gauge continues to show high
temperatures, see an authorized dealer.
Turbo Boost Gauge
(If Equipped)
Indicates the amount of manifold air
pressure in the engine.
DEF Gauge
(If Equipped)
Indicates the current DEF level.

HINTS ON CONTROLLING THE
INTERIOR CLIMATE -
VEHICLES WITH: AUTOMATIC
TEMPERATURE CONTROL
General Hints
Note: Prolonged use of recirculated air may
cause the windows to fog up.
Note: You may feel a small amount of air
from the footwell air vents regardless of the
air distribution setting. Note:
To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on.
Note: Do not place objects under the front
seats as this may interfere with the airflow
to the rear seats.
Note: Remove any snow, ice or leaves from
the air intake area at the base of the
windshield.
Note: To improve the time to reach a
comfortable temperature in hot weather,
drive with the windows open until you feel
cold air through the air vents.
Automatic Climate Control
Note: Adjusting the settings when your
vehicle interior is extremely hot or cold is
not necessary. Automatic mode is best
recommended to maintain set temperature.
Note: The system adjusts to heat or cool
the interior to the temperature you select
as quickly as possible.
Note: For the system to function efficiently,
the instrument panel and side air vents
should be fully open.
Note: If you select AUTO during cold
outside temperatures, the system directs
air flow to the windshield and side window
air vents. In addition, the blower motor may
run at a slower speed until the engine warms
up.
Note: If you select
AUTO during hot
temperatures and the inside of the vehicle
is hot, the system uses recirculated air to
maximize interior cooling. Blower motor
speed may also reduce until the air cools.

We recommend the following cold
weather idling guidelines:
•
You can use Motorcraft® cetane
improvers or non-alcohol-based
cetane improvers from a reputable
manufacturer as needed.
• Maintain the engine cooling system
properly.
• Avoid shutting the engine down after
an extensive idling period. Drive your
vehicle for several miles with the
engine at normal operating
temperatures under a moderate load.
• Consider using an engine block heater.
• For extended idle times use an
approved idle speed increase device.
Winter Operating Tips for Arctic
Operation -20°F (-29°C) and Below
The following information is a guideline
only and is not to be the only source of
possible solutions in resolving extreme
cold temperature issues.
Starting Aids WARNING: Do not use starting
fluid, for example ether, in the air intake
system. Such fluid could cause
immediate explosive damage to the
engine and possible personal injury.
The use of the factory engine block heater
assists in engine starting in extreme cold
ambient temperatures
See Engine Block
Heater (page 176). Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
the upfitter switches in the overhead
console. This allows the operator to
elevate the idle RPM for extended idle
periods, as well as aftermarket equipment
such as PTO operation. You must configure
this feature even if ordered from the
factory. See your authorized dealer for
required upfitting.
Operation in Snow and Rain
Vehicle operation in heavy snowfall or
extreme rain conditions may feed
excessive amounts of snow or water into
the air intake system. This could plug the
air filter with snow and may cause the
engine to lose power and possibly shut
down.
We recommend the following actions after
operating your vehicle up to
200 mi
(320 km) in snowfall or extreme rain:
• Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do not
remove the foam filter) and reset the
air filter restriction gauge.
Note: Removal of the foam filter degrades
your vehicle performance during snow and
hot weather conditions.
• Extreme rain: The air filter dries after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Refer to Air filter and restriction gauge in
the Maintenance chapter for more
information. See
Changing the Engine
Air Filter (page 347).

How to Start Operator Commanded
Regeneration
WARNING: Stay clear of the
exhaust tailpipe during regeneration. Hot
exhaust gases can burn you badly.
Note: You cannot use the operator
commanded regeneration until the diesel
particulate filter load percentage has
reached 100%. The diesel particulate filter
load percentage fluctuates up and down
when driving your vehicle due to active and
passive regenerations.
Note: During the use of operator
commanded regeneration, you may observe
a light amount of white smoke. This is
normal. You may not be able to use
operator commanded
regeneration if the service engine
soon warning lamp appears in the
information display
Information Display Procedure
Start with your vehicle engine and when it
has reached the normal operating
temperature, press the information display
control button on the steering wheel. See
Information Display Control
(page 81).
If a message advising that the exhaust
filter is full appears in the information
display, press the OK button as instructed.
Answer yes to this prompt and then follow
the next prompts regarding the exhaust
position required to initiate operator
commanded regeneration. Be sure to
understand each prompt. If you are not
sure what is being asked by each prompt,
contact an authorized dealer. The display
confirms the operation has started and
when it has finished. If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See
Information Messages
(page 120).
Answer yes to this prompt and then follow
the next prompts regarding exhaust
position required to initiate operator
commanded regeneration. Be sure to
understand each prompt. If you are not
sure what is being asked by each prompt,
contact an authorized dealer. The display
confirms the operation has started and
when it has finished. You can also drive to
clean the filter. When the system is at the point
of oversaturation, the service
engine warning lamp illuminates
and a message appears in the information
display. You cannot initiate filter cleaning.
You must have your vehicle checked as
soon as possible.
Once operator commanded regeneration
starts, engine speed increases to
approximately 1600 rpm and the cooling
fan speed increases. You will hear a
change in audible sound due to engine
speed and cooling fan speed increases.
It is not necessary to open the hood on the
engine compartment. Once operator
commanded regeneration completes, the
engine speed returns to normal idling. The
exhaust system remains very hot for
several minutes even after regeneration is
complete. Do not reposition the vehicle
over materials that could burn until the
exhaust system has had sufficient time to
cool. Depending on the amount of soot
collected by the diesel particulate filter,
ambient temperature and altitude,
operator commanded regeneration lasts
approximately 30 minutes.
