Diagram of BMW 740il cooling system?

The cooling system of the BMW 740iL includes key components such as the radiator, water pump, thermostat, coolant reservoir, and hoses. Coolant circulates from the engine to the radiator, where it dissipates heat before returning to the engine. The thermostat regulates the flow of coolant based on temperature, ensuring optimal engine performance. The system also features a fan to enhance airflow through the radiator, particularly when the vehicle is stationary or moving at low speeds.
