Draining WARNING: To avoid personal injury, do not unscrew the coolant pressure relief cap while engine is operating or hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. CAUTION: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated it must be recycled or disposed of correctly.Note: About 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.
Filling-Bleeding CAUTION: Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the proper concentration and fluid level in the degas bottle.When adding engine coolant, use a 60/40 mixture of clean drinkable water and engine coolant.To maintain the integrity of the coolant and the cooling system:Add Premium Engine Coolant E2FZ-19549-AA (CXC-8-B in Canada, F5FZ-19549-CC in Oregon) or an equivalent meeting Ford specification ESE-M971144-A. Do not add orange-colored EXTENDED LIFE COOLANT such as F6AZ-19544-A or equivalent, meeting Ford specification WSS-MM44-D. Mixing coolants may degrade the coolant's corrosion protection. Do not add alcohol or methanol or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing. Do not mix with recycled coolant unless it meets the requirements of Ford specification ESE-M97B44-A. Not all coolant recycling processes meet this specification; use of such a coolant may harm the engine and cooling system components.
