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.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community's regulations and standards for recycling
and disposing of automotive fluids.
Severe climates
If you drive in extremely cold climates:
Note: It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
Note: A coolant concentration of 60% will provide improved freeze point
protection. Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine coolant
and may cause engine damage.
If you drive in extremely hot climates:
Note: It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
Note: A coolant concentration of 40% will provide improved overheat
protection. Decreased engine coolant concentrations below 40% will
decrease the corrosion/freeze protection characteristics of the engine
coolant and may cause engine damage.
Vehicles driven year-round in non-extreme climates should use prediluted
engine coolant for optimum cooling system and engine protection.
Engine fluid temperature management (EcoBoost™ engine only)
WARNING: To reduce the risk of collision and injury, be prepared
that the vehicle speed may reduce and the vehicle may not be able
to accelerate with full power until the fluid temperatures reduce.
Your vehicle has been designed to pull a trailer, but because of the added
load, the vehicle's engine may temporarily reach higher temperatures
during severe operating conditions such as ascending a long or steep
grade while pulling a trailer in hot ambient temperatures.
