General maintenance information • decreased engine coolant concentrations below 40% will decrease the freeze protection characteristics of the engine coolant and may cause engine damage. • refer to the chart on the coolant container to ensure the coolant concentration in your vehicle will provide adequate protection at the temperatures in which you drive. Vehicles driven year-round in non-extreme climates should use a 50/50 mixture of engine coolant and distilled water for optimum cooling system and engine protection. Coolant conditioner (liquid) For engines filled with green-colored Motorcraft Premium Engine Coolant, a supplemental coolant additive FW-16 meeting Ford specification ESN-M99B169-A has been added to the coolant in this engine. This additive aids in the prevention of rust and scale buildup on the internal parts of the cooling system. Prevention of rust and scale buildup allows for proper dissipation of heat generated by combustion. See the scheduled maintenance guide for recommended intervals.
