How do you bleed cooling system on a 1.6 zetec s fiesta?

To bleed the cooling system on a 1.6 Zetec S Fiesta, first ensure the engine is cool and the radiator cap is off. Start the engine and let it run until it reaches operating temperature, allowing the thermostat to open. Keep an eye on the coolant level and add coolant as necessary while squeezing the upper radiator hose to help release any trapped air. Once the air bubbles have stopped and the coolant level stabilizes, replace the radiator cap and check for leaks.
