additives in your gasoline powered vehicle. These additives may harm your engine cooling system. Follow the recommended service interval for changing your engine coolant. NOTE: When adding to or changing your engine coolant, it is important to maintain a coolant concentration between 40% ( 11˚F [ 24˚C]) and 60% ( 62˚F [ 52˚C]) depending on your local climate conditions. When coolant concentration falls below 40%, you will lose freeze protection; above 60%, your engine may overheat on a warm day. If coolant concentration is outside this range, you may lose corrosion and rust protection for the metals in your engine cooling system. NOTE: Do not use an engine coolant that does not meet all 14 requirements of Ford specification ESE-M97B44-A. The use of a coolant that does not meet the 14 requirements may void your warranty for the engine cooling system. Use only a premium, nationally recognized brand name engine coolant. 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. NOTE: Always dispose of used automotive fluids in a responsible manner. Follow your community's standards for disposing of these types of fluids. Call your local recycling center to find out about recycling automotive fluids. Leave the coolant in all year. Make sure that the coolant will not freeze at the temperature level in which you usually drive during winter months. Keep an engine coolant in your engine that has a protection rating of at least 20˚F ( 29˚C). 322
