Maintenance and care The cooling system in your vehicle is filled with Ford Extended Life Engine Coolant F6AZĆ19544ĆAA or equivalent meeting Ford specification WSSĆM97B44ĆD. To maintain the integrity of the coolant and the cooling system and maintain the warranty on the cooling system: • Add the type of coolant originally equipped in your vehicle. If you are unsure which type of coolant your vehicle requires, contact your local dealer. • Do not mix the factoryĆfilled coolant with a greenĆcolored Premium Engine Coolant such as E2FZĆ19549ĆAA, meeting Ford specification ESEĆM97B44ĆA. Mixing of Ford Extended Life Engine Coolant with a conventional green coolant can result in degraded corrosion protection. • A large amount of water without engine coolant may be added, in case of emergency, to reach a vehicle service location. In this instance, the cooling system must be drained and refilled with a 50/50 mixture of engine coolant and distilled water as soon as possible. Water alone (without engine coolant) can cause engine damage from corrosion, overheating or freezing.
