How do you bleed renualt megane cooling system?

To bleed the cooling system of a Renault Megane, first ensure the engine is cold and the radiator cap is removed. Start the engine and let it reach operating temperature, allowing the thermostat to open. With the heater set to maximum, check for air bubbles in the coolant reservoir; if present, squeeze the upper radiator hose gently to help release trapped air. Once the bubbling stops and the coolant level stabilizes, replace the radiator cap and check the coolant level again after the engine cools down.
