2021 FORD EXPEDITION coolant temperature

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 111).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 339).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle. There are some things to keep in mind that
may improve your fuel economy:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back
home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
There are also some things you may want
to avoid doing because they reduce your
fuel economy:
• Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly
terrain.
• Do not rest your foot on the brake
pedal while driving.
• Avoid carrying unnecessary weight.

ENGINE OIL CHECK
To check the engine oil level consistently
and accurately, do the following:
1. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run the engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes for the oil to drain into the oil
pan. Checking the engine oil level too
soon after you switch the engine off
may result in an inaccurate reading.
5. Open the hood. See
Opening and
Closing the Hood (page 335). 6. Remove the dipstick and wipe it with
a clean, lint-free cloth. See
Under
Hood Overview (page 336).
7. Reinstall the dipstick and remove it again to check the oil level. See
Engine Oil Dipstick
(page 337).
8. Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See
Capacities
and Specifications (page 392).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.
Adding Engine Oil WARNING: Do not remove the filler
cap when the engine is running.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.

Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 392).
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 may 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 a short period for the engine to cool.

Expedition (TB8) Canada/United States of America, enUSA, First-Printing Maintenance

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.
You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no
need to stop your vehicle. You can
continue to drive. The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after
several minutes, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See
Scheduled
Maintenance (page 483).
The automatic transmission does not have
a transmission fluid dipstick.
