The rear power distribution box is in the
engine compartment. See Under Hood
Overview (page 160). It has high-current
fuses that protect your vehicle's main
electrical systems from overloads. These
are in the right side of the engine
compartment behind an access door in the
engine surround panel. If replacement of
these high-current fuses is required, see
an authorized dealer. If you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery

ENGINE OIL CHECK
Note: Use a thick cloth to protect your hand
when removing the oil tank cap and dipstick.
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 (Coolant
temperature of 190°F (87.7°C) or
higher).
3. Turn the engine off and wait two to three minutes.
4. Make sure that your vehicle is on level ground.
5. Open the rear hatch. See
Opening
and Closing the Hood (page 157).
6. Unscrew the oil tank cap to remove the
dipstick and wipe it with a clean,
lint-free cloth. See
Under Hood
Overview (page 160). 7. Replace the cap and dipstick and
remove it again to check the oil level.
See
Engine Oil Dipstick (page 161).
8. Make sure that the oil level is between
the minimum and the maximum marks.
If the oil level is at the minimum mark,
add oil immediately. See
Capacities
and Specifications (page 204).
9. If the oil level is correct, replace the cap
and dipstick and make sure it is fully
tightened.
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)
.
Note: High performance vehicles tend to
be driven in such a way the engine
experiences high speed and high load. As a
result, some oil consumption could occur
between oil changes. We recommend that
you check the oil level on a regular basis.
Adding Engine Oil WARNINGS
Do not remove the filler cap when
the engine is running.
Do not add engine oil when the
engine is hot. Hot engine oil can burn
you badly.
Note:
Use a thick cloth to protect your hand
when removing the oil tank cap and dipstick.
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.
To top up the engine oil level do the
following:
161
Ford GT (CGX), enUSA, Edition date: 201711, First Printing MaintenanceE230019

1. Unscrew the oil tank cap.
2.
Add engine oil by pouring oil that meets
Ford specifications into the oil tank.
See Capacities and Specifications
(page 204). You may have to use a
funnel to pour the engine oil into the
opening.
3. Recheck the oil level.
4. If the oil level is correct, replace the cap
and the dipstick and make sure it is
fully tightened.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil tank cap
and dipstick correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.
ENGINE COOLANT CHECK WARNINGS
Never remove the coolant reservoir
cap when the engine is running or
hot.
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. 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 274).
Note: Make sure that the coolant level is
between the
MIN and MAXmarks on the
coolant reservoir when the engine is cold.
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 MIN / MAX 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 inch (20 mm) below the black top. 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
Never remove the coolant reservoir
cap when the engine is running or
hot.
