Maintenance
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Note: Do not use stop leak pellets, cooling
system sealants or additives as they can
cause damage to the engine cooling or
heating systems. The vehicle warranty does
not cover this damage.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See Adding Engine Coolant
in this chapter.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red. As long as the
engine coolant is clear and uncontaminated,
this color change does not indicate that the
engine coolant has degraded or that you
drain the engine coolant, flush the system
or replace the engine coolant.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant
concentration should be tested with a
refractometer, for example Robinair®
coolant and battery refractometer 75240.
We do not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
•
Do not mix different colors or types of
coolant in your vehicle. Make sure the
correct coolant is used. Mixing of
engine coolants may harm the engine’s
cooling system. The use of incorrect
coolant may harm engine and cooling
system components and may void the
warranty. Use prediluted engine
coolant meeting the Ford specification.
See Capacities and Specifications
(page 241).
Note: Automotive fluids are not
interchangeable. Do not use engine coolant,
antifreeze or windshield washer fluid outside
of its specified function and vehicle location.
Adding Engine Coolant
WARNINGS
•
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, you
must have the cooling system drained,
chemically cleaned with Motorcraft
Premium Cooling System Flush, and
refilled with engine coolant as soon as
possible. Water alone (without engine
coolant) can cause engine damage, for
example corrosion, overheating or
freezing.
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you.
Do not put engine coolant in the
windshield washer fluid reservoir. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.
•
•
Do not use alcohol, methanol, brine or
any engine coolants mixed with alcohol
or methanol antifreeze. Alcohol and
other liquids can cause engine damage,
for example overheating or freezing.
Do not add coolant further than the
MAX mark.
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 the cap is loosened
slightly.
Do not add extra inhibitors or additives
to the coolant. These can be harmful
and compromise the corrosion
protection of the engine coolant.
