Ford GT (2018 year). Manual — part 41

2. Leave the engine running until the

coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, 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 274).

The automatic transmission does not have
a transmission fluid dipstick.

Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission
does not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.

Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.

BRAKE FLUID CHECK

WARNINGS

Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of

incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other

materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death.

Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with

plenty of water and contact your physician.

A fluid level between the MAX and
MIN lines is within the normal
operating range and there is no need

to add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your
vehicle checked immediately.

E244129

To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.

Only use fluid that meets Ford
specifications. See Capacities and
Specifications (page 204).

POWER STEERING FLUID
CHECK

The hydraulic fluid reservoir is under the
hood. The fluid is used for power steering,
active aerodynamics and the active
hydraulic suspension. Keep the fluid level
between MIN and MAX marks as shown
on the reservoir.

E248557

Note: This procedure must be followed to
prevent over filling of the reservoir.

1.

Start the engine and make sure that
the steering wheel is at the straight
ahead position. Do not move the
steering wheel after this time.

2. Allow the engine to idle in Park for 2

minutes then shut the engine off.

3. After the engine has been off for 5

minutes, check the hydraulic fluid level
in the reservoir.

4. The MIN / MAX marks are on the front

face of the reservoir. If the level is
above the MIN line on the reservoir DO
NOT add fluid.

5. If the level is below the MIN line, add

only enough fluid to bring the level to
a point between the MIN and MAX
lines.

6. DO NOT add fluid past the MAX line.

WASHER FLUID CHECK

WARNING

If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze

protection. Failure to use washer fluid with
antifreeze protection in cold weather could
result in impaired windshield vision and
increase the risk of injury or accident.

Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See Capacities and
Specifications (page 204).

State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle’s paint finish, wiper blades or
washer system.

FUEL FILTER

Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.

CHANGING THE 12V BATTERY

WARNING

Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after

handling.

The Ford GT uses a lithium Ion battery.

The battery is located inside the right front
fender. For battery maintenance or
replacement, contact an authorized dealer.

When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.

Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This may also affect the
performance of other electrical systems in
the vehicle.

Because your vehicle’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance.

To restore the settings, do the following:

1.

Apply the parking brake.

2. Shift into park (P) or neutral (N).

3. Switch off all accessories.

4. Press the brake pedal and start your

vehicle.

5. Run the engine until it reaches normal

operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 212). Reset the radio
station presets. See Audio System
(page 212).

6. Allow the engine to idle for at least one

minute.

7.

Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.

Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.

Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.

Battery Charger and Maintainer

If you plan to have your GT parked for more
than two weeks without driving it, connect
the battery charger and maintainer
provided. This charger connects simply to
the jump start(+) and (-) posts as shown
in the illustration below.

E235907

1.

Connect the positive (+) red cable to
the positive (B) post.

2. Connect the negative (-) black cable

to the negative (A) post.

The battery charger and maintainer
charges the battery to a full charge and
then monitor the charge as the car sits. If
the battery charge level drops, the
maintainer turns on to keep the battery
fully charged. You can keep the car stored
with the charger and maintainer attached.
For further information on the charger, see
the instructions provided with the charger.

Note: If the battery state of charge has
dropped below 10.5 volts, the battery will
have gone into its under voltage protection
mode. If this has occurred, connect the
charger and press the reset button on the
charger for 10 seconds. this will wake up the
battery to allow it to receive a charge.

Note: The GT battery charger and
maintainer is designed for the Lithium
battery used on Ford GT. Use only this
device. A charger designed for a lead acid
battery may damage the lithium battery in
your GT.

Battery Management System

(If

Equipped)

The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables the electrical systems to protect
the battery.

Use the charger to bring the battery back
to full charge.

Electrical Accessory Installation

Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.

CHECKING THE WIPER
BLADES

E142463

Run the tip of your fingers over the edge of
the blade to check for roughness.

Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.

CHANGING THE WIPER
BLADES

Replacement blades are available at your
Ford dealer.
