Abstract With the introduction of EURO VI emission legislation, many innovations in the cooling system and its components became necessary to deliver the increased cooling performance requirements without an increase in fuel consumption. Some examples are radiators charge air coolers and EGR coolers with a high performance density, new fan actuators with improved control capabilities and, for the first time, a Visco actuator for the coolant pump. Whilst the components and there interaction got optimized, the principal architecture of the cooling module was, except some few exceptions, the same as originally introduced in the 1980s: The direct cooling system. In this system the individual cooling tasks are cooled directly in individual components by cooling air. This is typically the HVAC condenser, the charge air cooler and the radiator.
