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 radiator 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 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. Use Ford Premium Cooling System Fluid E2FZ-19549-AA (in Canada, Motorcraft CXC-8-B) or an equivalent engine coolant that meets Ford Specification ESE-M97B44-A. Leave the engine coolant in all year. Make sure that the coolant will not freeze at the temperature level in which you drive during winter months. Keep a mixture of engine coolant in your engine that has a protection rating of at least -34˚F (-37˚C), or whatever protection rating is appropriate for the climate in which you live. 256
