How do you bleed air out of coolant system 2003 ford excursion 5.4 liter?

To bleed air out of the coolant system in a 2003 Ford Excursion with a 5.4-liter engine, first ensure the engine is cool and the radiator cap is off. Start the engine and let it idle with the heater set to maximum heat; this will help circulate the coolant and air. As the engine warms up, keep an eye on the coolant level and add coolant as necessary. Once the thermostat opens, you should see air bubbles escaping, and the level should stabilize—recheck and secure the radiator cap afterward.
