Abstract
A cooling system for a vehicle is configured so as to adjust draft volume to the radiator through which engine cooling water is circulated on the basis of the engine operating condition e.g. the temperature of engine cooling water. The cooling system comprises a plurality of motor-fans for cooling the radiator, engine cooling water sensor means provided at radiator hoses, and operational mode control means responsive to the sensor means to selectively control operational modes including a parallel drive mode, a serial drive mode, a partial or single drive mode and an OFF mode. Thus, a desired power supply control for motor-fans is carried out in accordance with an operational mode selected by the operational mode control means, thereby enabling to finely adjust draft volume to effect a desired cooling of the engine.
