2021 FORD F-450 engine

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.

During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator illuminates
when the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See Fuel Quality (page 187).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.
Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.
