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
322
20˚F ( 29˚C).
