ABSTRACT:
Engine cooling system including cooling water passages having cooling water jackets formed respectively in the hot temperature portion and the cold temperature portion of the engine and water pumps for circulating cooling water through the water passages. Driving motors are provided for driving the water pumps and a control circuit for the motors receives an engine speed signal so that the water pump for the water passage to the cold temperature portion of the engine is stopped when the engine temperature is low so that the engine can be warmed up rapidly while maintaining a cooling water circulation through the water passage in the hot temperature portion for preventing local overheating of the engine.
