Abstract

A cooling control apparatus for an automobile engine having a radiator and two or more electrically operated fans for circulating air through the radiator. Each fan is operated in response to a different predetermined temperature of the cooling water in the radiator so that first one fan is activated under normal operation and the second fan is operated only under heavier loads or high ambient conditions requiring additional cooling. In one embodiment a fan is operated upon activation of the air-conditioning system to cool its condenser regardless of the cooling water temperature.
