ABSTRACT:
The cooling system of an engine consists of a cooling fan for cooling an engine coolant and a drive pulley which is, in turn, drivably rotated by the crank shaft of the engine. The mechanical connection between the drive pulley and the cooling fan is released during engine acceleration under urban area cruising conditions, in order to stop or slow down the rotational speed of the cooling fan.
