Maintenance and care Checking and adding washer fluid for the liftgate The opening for this reservoir is located on the left side of the vehicle above the tail lamp. Be sure to close the cover after filling and before closing the liftgate. The reservoir must be filled slowly to allow trapped air to escape. Use of a funnel is recommended for easier filling. CHECKING AND ADDING ENGINE COOLANT Check the engine coolant level in the reservoir at least once a month. If the engine coolant has not been checked for a long period of time, the engine coolant reservoir may eventually empty. If this occurs, add engine coolant to the coolant reservoir. For more information on engine coolant maintenance, refer to Adding engine coolant to the reservoir in this chapter. Automotive fluids are not interchangeable; do not use engine coolant, antifreeze, or windshield washer fluid outside of their specified function and vehicle location. When adding engine coolant Ford recommends Ford Premium Cooling System fluid, which is an optimized formula that will protect all metals and rubber elastomers used in Ford engines for four years 145
