Change your engine coolant according to the appropriate schedule listed
in the Scheduled Maintenance Guide.
Before adding engine coolant, check the color of the coolant in your
vehicle.
For vehicles with green coolant, 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.
Do not add orange coolant or recycled coolant to your vehicle
originally equipped with conventional green coolant.
For vehicles with orange coolant, use Ford Extended Life Engine
Coolant F6AZ-19544–AA or a DEX-COOL
t
equivalent that meets Ford
specification WSS-M97B44–D.
Do not add conventional green coolant or recycled coolant to
your vehicle originally equipped with orange coolant.
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 your 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.
For vehicles with green coolant, 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.
For vehicles with orange coolant, no recycling process has been
approved at this time 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.
