ABSTRACT:
Engine cooling system including a cooling water passage having cooling water jackets formed in the engine and a water pump for circulating cooling water through the water passage. A driving motor is provided for driving the water pump and a control circuit for the motor receives an engine speed signal so that the speed of the water pump is decreased to a predetermined low level when the engine temperature is low so that the engine can be warmed up rapidly while maintaining a cooling water circulation for preventing local overheating of the engine.
