vehicle’s engine cooling system.
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,
refer to Refill capacities in the
Capacities and specifications
chapter.
Have your dealer check the engine
cooling system for leaks if you
have to add more than a liter
(quart) of engine coolant per
month.
Severe winter climate
If you drive in extremely cold
climates (less than –36°C [–34°F]),
it may be necessary to increase the
coolant concentration above 50%.
