Draining and filling the complex cooling system:
Because this car has a mid-engined design, the cooling system is more complex than in a conventional front-engine vehicle. For adequate airflow, the radiator must be located at the front of the car. The waterpump, powered by the engine, must circulate coolant through a complex feed and return system to the radiator for heat exchange. For some great pictures of the MR2 cooling system, check out this website.
