ABSTRACT:
A tandem fan for a motor-vehicle radiator has one fan impeller driven via a fluid friction clutch by the engine shaft. Both fan impellers have belt pulleys with a common driving belt. Overrunning clutches for the two fan impellers ensure the impellers are driven by the drive shaft which is running faster.
