NOTE: When you change or add engine coolant, it is important to maintain your engine coolant concentration between 40% (-11˚F [-24˚C]) and 60% (-62˚F [-52˚C]), depending on your local climate conditions. Below 40% you will lose freeze protection and above 60% your engine may overheat on a warm day. NOTE: The use of an improper coolant may void your warranty for the engine cooling system. Use only a premium, nationally recognized brand name engine coolant. Do not use alcohol, methanol antifreeze or engine coolant mixed with alcohol or methanol antifreeze. If you do not use the proper coolant, the aluminum engine on your vehicle will corrode. Ford Motor Company expressly authorizes the Ford Rotunda engine coolant recycling process and chemicals. Use only Ford Rotunda recycled engine coolant or an equivalent non-Ford Rotunda recycled engine coolant that is certified by the supplier to meet Ford specification ESE-M97B44-A. 270
