2018 FORD F450 SUPER DUTY 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 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 gradient. Switch the ignition on. The fuel gauge will
indicate approximately how much fuel is
left 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.
The needle should move toward F when
you refuel your vehicle. If the needle points
to E after adding fuel, this indicates your
vehicle needs service soon.
After refueling some variability in needle
position is normal:
•
It may take a short time for the needle
to reach F after leaving the gas station.
This is normal and depends upon the
slope of pavement at the gas station.
• The fuel amount dispensed into the
tank is a little less or more than the
gauge indicated. This is normal and
depends upon the slope of pavement
at the gas station.
• If the gas station nozzle shuts off
before the tank is full, try a different
gas pump nozzle.
Low Fuel Reminder
A low fuel reminder triggers when the
distance to empty value reaches 50 mi
(80 km) to empty, with additional
warnings at 25 mi (40 km), 10 mi (20 km)
and 0 mi (0 km) to empty, provided the
message is cleared each time. An
additional warning at
75 mi (120 km) to
empty is provided when the MyKey is being
used.
Variations:
Note: The distance-to-empty warning can appear at different fuel gauge positions depending
on fuel economy conditions. This variation is normal.

MANUAL CLIMATE CONTROL (If Equipped)
Fan speed control:
Adjusts the volume of air circulated in the vehicle.
A
Power:
Press to switch the system on and off. When the system is off, it
prevents outside air from entering the vehicle.
B
Air distribution control:
Press to switch air flow from the windshield,
instrument panel, or footwell vents on or off. You can distribute air through any
combination of these vents.
C
Note:
At least one of these buttons remain on while the system is on.
Recirculated air:
Press to switch between outside air and recirculated air. The
air currently in the passenger compartment recirculates. This may reduce the
time needed to cool the interior (when used with A/C) and reduce unwanted
odors from entering your vehicle.
D
Note:
Recirculated air may turn off (or prevent you from switching on) in all air
flow modes except MAX A/C to reduce the risk of fogging. Recirculation may
also turn on and off in Panel or Panel/Floor air flow modes during hot weather
in order to improve cooling efficiency.
Temperature control:
Adjusts the temperature of the air circulated in your
vehicle.

MAX Defrost: Turn to the right to switch on defrost. Air flows through the
windshield vents and the fan adjusts to the highest speed. You can also use
this setting to defog and clear the windshield of a thin covering of ice. The heated
rear window also turns on when you select maximum defrost.
F
Note:
To prevent window fogging, you cannot select recirculated air when
maximum defrost is on.
MAX A/C:
Turn to the left for maximum cooling. Recirculated air flows through
the instrument panel vents, air conditioning turns on and the fan adjusts to the
highest speed.
G
A/C:
Press to switch the air conditioning on or off. Use A/C with recirculated
air to improve cooling performance and efficiency.

HINTS ON CONTROLLING THE
INTERIOR CLIMATE
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.
151
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, First Printing Climate Control

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.
Manual Climate Control
Note: To reduce fogging of the windshield
during humid weather, adjust the air
distribution control to the windshield air
vents position. Automatic Climate Control
Note:
Adjusting the settings when your
vehicle interior is extremely hot or cold is
not necessary. The system automatically
adjusts to heat or cool the interior to your
selected temperature as quickly as possible.
For the system to function efficiently, the
instrument panel and side air vents should
be fully open.
Note: If you select AUTO during cold
temperatures, the system directs airflow to
the windshield and side window vents. In
addition, the fan 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 automatically uses
recirculated air to maximize interior cooling.
Fan 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 185). 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 364).
