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.
At normal operating temperature, the
engine coolant temperature will be in the
middle range of the gauge. If the engine
coolant temperature exceeds the normal
range, the gauge will be highlighted. Stop
your vehicle as soon as safely possible,
switch off the engine and let it cool.
Engine Oil Temperature Gauge
If the engine oil temperature exceeds the
normal range, the engine is overheating.
Reduce engine speed as soon as safely
possible to allow the engine to cool. If you
continue to operate the engine at high
engine speeds, the engine speed reduces
automatically to prevent engine damage.
Engine Oil Pressure Gauge
Oil pressure varies with engine speed. The
pressure rises as engine speed rises and
drops as engine speed drops. If the pressure drops below the normal
range of the gauge, a warning lamp
illuminates and a message appears in the
information display. Stop your vehicle as
soon as it is safe to do so and switch the
engine off. Check the engine oil level.
Gauge Mode
On the right side of the instrument cluster,
you can configure which gauges are
displayed.
WARNING LAMPS AND
INDICATORS
The following warning lamps and
indicators alert you to a vehicle condition
that may become serious. Some lamps
illuminate when you start your vehicle to
make sure they work. If any lamps remain
on after starting your vehicle, refer to the
respective system warning lamp for further
information.
Note:
Some warning indicators appear in
the information display and operate the
same as a warning lamp but do not
illuminate when you start your vehicle.
Anti-Lock Braking System If it illuminates when you are
driving, this indicates a
malfunction. You will continue
to have the normal braking system
(without ABS) unless the brake system
warning lamp is also illuminated. Have the
system checked by your authorized dealer.

CHANGING THE ENGINE AIR
FILTER
Please see an authorized dealer.
ENGINE COOLANT CHECK 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. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
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. WARNING:
Do not add coolant
further than the MAX mark.
Check the concentration and level of the
coolant only when the engine is cold at the
intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 279).
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.
The coolant reservoir is behind an access
panel on the left side of the of the engine
compartment. The cold minimum and
maximum marks are located on the front
inboard corner of the coolant reservoir.
MAX
is located just below where the black
top meets the translucent reservoir lower.
MIN
is located 3/4 in (20 mm) below the
black top. 158
Ford GT (CGX) Canada/United States of America, enUSA, Edition date: 202010, First-Printing MaintenanceE244128

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 do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant
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.
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.
It is very important to use prediluted
coolant meeting the correct specification
to avoid plugging the small passageways
in the engine cooling system. See
Capacities and Specifications
(page
205). Do not mix different colors or types
of coolant in your vehicle. Mixing of engine
coolants or using an incorrect coolant may
harm the engine or cooling system
components and may not be covered by
the vehicle warranty. Note:
Coolants marketed for all makes and
models may not meet our specifications
and may cause damage to the cooling
system. Resulting component damage may
not be covered by the vehicle warranty.
If the coolant level is at or below the
MIN
mark, add prediluted coolant immediately.
Only check the coolant level or add coolant
when the system is cold.
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 205).
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. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.
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.

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. Contact the Ford GT Concierge to obtain assistance.
See About This
Manual (page 5).
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.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management 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.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
