The coolant concentration should be
maintained 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 such
as Robinair® Coolant and Battery
Refractometer 75240. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Adding Engine Coolant
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 your engines cooling
system. The use of an improper 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 346).
In case of emergency, a large amount of
water without engine coolant may be
added in order to reach a vehicle service
location. In this instance, the cooling
system must be 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 from corrosion,
overheating or freezing.
Do not use alcohol, methanol, brine or
any engine coolants mixed with alcohol
or methanol antifreeze (coolant). 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 engine coolant.
Unscrew the cap slowly. Any pressure will
escape as you unscrew the cap.
Add prediluted engine coolant meeting the
Ford specification. See Capacities and
Specifications (page 346).
Whenever coolant has been added, the
coolant level in the coolant reservoir should
be checked the next few times you drive the
vehicle. If necessary, add enough prediluted
engine coolant to bring the coolant level to
the proper level.
Recycled Engine Coolant
We do not recommend the use of recycled
engine coolant since a Ford-approved
recycling process is not yet available.
