To bleed the cooling system of a 2001 BMW 525, first ensure the engine is cold and the radiator cap is removed. Start the engine and turn the heater to the maximum setting. Allow the engine to reach operating temperature, and monitor the coolant level in the expansion tank; add coolant as necessary. Once the thermostat opens (indicated by warm air from the heater), check for air bubbles in the tank, and repeat the process until no bubbles are visible and the coolant level stabilizes. Finally, replace the radiator cap and check the coolant level again after the engine cools down.
