• 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 prediluted
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 escapes as you unscrew the cap.
Add prediluted engine coolant meeting the Ford specification.
See Capacities and Specifications for more information.
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
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Always dispose of used automotive fluids in a responsible manner. Follow
your community's regulations and standards for recycling and disposing
of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides improved freeze point
protection. Engine coolant concentrations above 60% decrease the
overheat protection characteristics of the engine coolant and may
cause engine damage.
If you drive in extremely hot climates:
• It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
• A coolant concentration of 40% provides improved overheat
protection. Engine coolant concentrations below 40% decrease the
corrosion and freeze protection characteristics of the engine coolant
and may cause engine damage.
