Maintenance and care 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. If your coolant is not green in color, consult your dealer or a qualified technician before adding coolant. Do not add orange coolant or recycled coolant to your vehicle originally equipped with conventional green 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 the warranty of your vehicle's engine cooling system. 194
