2018 FORD FUSION engine coolant

AUTO-START-STOP (If Equipped)
The system helps reduce fuel consumption
by automatically shutting off and restarting
the engine while your vehicle is stopped.
The engine will restart automatically when
you release the brake pedal. In some
situations, your vehicle may restart
automatically, for example:
• To maintain interior comfort
• To recharge the battery
Note: Power assist steering is turned off
when the engine is off. WARNINGS
Always fully apply the parking brake.
Make sure you shift into park (P) for
vehicles with an automatic
transmission. Switch the ignition off and
remove the key whenever you leave your
vehicle. Before opening the hood or
performing any maintenance, fully
apply the parking brake, shift into
park (P) or neutral (N) and switch the
ignition off. Always switch the ignition off before
leaving the vehicle. If the ignition is
switched on an automatic restart
may occur at any time. The system may require the engine
to automatically restart when the
auto-start-stop indicator illuminates
green or flashes amber. Failure to follow
this instruction could result in personal
injury. The Auto-Start-Stop system status is
available at a glance within the information
display. See Information Displays (page
96
). Enabling Auto-Start-Stop
The system is automatically enabled every
time you start your vehicle if the following
conditions are met:
•
The Auto-Start-Stop button is not
pressed (not illuminated).
• Your vehicle exceeds an initial speed
of
3 mph (5 km/h) after you have
initially started the vehicle.
• Your vehicle is stopped.
• Your foot is on the brake pedal.
• The transmission is in drive (D).
• The driver's door is closed.
• There is adequate brake vacuum.
• The interior compartment has been
cooled or warmed to an acceptable
level.
• The front windshield defroster is off.
• The steering wheel is not turned rapidly
or is not at a sharp angle.
• The vehicle is not on a steep road
grade.
• The battery is within optimal operating
conditions (battery state of charge and
temperature in range).
• The engine coolant is at operating
temperature.
• Elevation is below approximately
10,000 ft (3,050 m)
.
• Ambient temperature is moderate. The green Auto-Start-Stop
indicator light on the instrument
cluster will illuminate to indicate
when the automatic engine stop occurs. If the instrument cluster is
equipped with a grey
Auto-Start-Stop indicator light,
it is illuminated when automatic engine
stop is not available due to one of the
above noted conditions not being met.

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. Do not put coolant in the windshield
washer reservoir. If sprayed on the
windshield, coolant could make it
difficult to see through the windshield. To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly. Do not add coolant further than the
MAX
mark.
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 475).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
262
Fusion (CC7) Canada/United States of America, enUSA, Edition date: 201705, Second Printing Maintenance

Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We
recommend, Robinair® Coolant and
Battery Refractometer 75240 (Rotunda
tool part number: ROB75240). We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
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.
Adding Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Failure to follow this
instruction could result in personal
injury. 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. It is very important to use prediluted
coolant meeting the correct specification
in order to avoid plugging the small
passageways in the engine cooling system.
See Capacities and Specifications
(page 322). Incorrect prediluted coolant
use can cause damage not covered by the
vehicle Warranty. If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.
2. Add prediluted coolant meeting the correct specification. See
Capacities
and Specifications (page 313).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap, turn
it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle.
Note: During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
Do not mix different colors or types of
prediluted coolant in your vehicle. Mixing
of prediluted coolant or using an incorrect
prediluted coolant may harm the engine
or cooling system components and may
not be covered by the vehicle Warranty.
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the cooling system.
3. Refill with prediluted coolant as soon as possible.
Water alone, without prediluted coolant,
can cause engine damage from corrosion,
overheating or freezing.
263
Fusion (CC7) Canada/United States of America, enUSA, Edition date: 201705, Second Printing Maintenance

Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community's regulations and standards
for recycling and disposing of automotive
fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage. If you drive in extremely hot climates:
•
It may be necessary to decrease the
coolant concentration to 40%.
• A coolant concentration of 40%
provides improved overheat
protection. Coolant concentrations
below 40% decrease the freeze and
corrosion protection characteristics of
the coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
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.
264
Fusion (CC7) Canada/United States of America, enUSA, Edition date: 201705, Second Printing Maintenance

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
WARNINGS
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. 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. 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.
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.
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 pull off the road. You can continue to
drive your vehicle.
