Recycled Engine Coolant
Ford Motor Company recommends that Ford
and Lincoln-Mercury dealers use recycled engine
coolant produced by Ford-approved processes.
Not all coolant recycling processes produce
coolant which meets Ford specification
ESE-M97B44-A, and use of such coolant may
harm engine and cooling system components.
Always dispose of used automotive fluids in a
responsible manner. Follow your community's
regulations and standards for recycling and
disposing of automotive fluids.
Coolant Refill Capacity
To find out how much fluid your vehicle's
cooling system can hold, see Refill capacities for
fluids in the Index.
Have your dealer check the engine cooling
system for leaks if you have to add more than a
quart (liter) of engine coolant per month.
Severe Winter Climate
If you drive in extremely cold climates (less than
34˚F [ 36˚C]), it may be necessary to increase
the coolant concentration above 50%. Refer to
the chart on the coolant container to ensure the
coolant concentration in your vehicle is such that
the coolant will not freeze at the temperature
level in which you drive during winter months.
Never increase the engine coolant concentration
above 60%. Leave a 50/50 mixture of engine
coolant and water in your vehicle year-round in
non-extreme climates.
