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 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 or an equivalent
engine coolant that meets Ford Specification ESE-M97B44-A.
