5. Stand away from the radiator opening. Hot
steam may blow out or hot engine coolant
may even splash out.
Use Ford Premium Cooling System Fluid
E2FZ-19549-AA (in Canada, Motorcraft CXC-8-B)
or an equivalent premium engine coolant that
meets Ford specification ESE-M97B44-A. Ford
Premium Engine Coolant is an optimized
formula that will protect all metals and rubber
elastomers used in Ford cooling systems for 4
years or 50,000 miles (80,000 km).
Do not use alcohol or methanol antifreeze or any
engine coolants mixed with alcohol or methanol
antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may
harm your engine cooling system. The use of an
improper coolant may void the warranty of your
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.
