Description






DESCRIPTION





The thermal viscous fan drive (3) is a silicone fluid filled coupling used to connect the fan blades to the water pump shaft (4). The coupling allows the fan to be driven in a normal manner. This is done at low engine speeds while limiting the top speed of the fan to a predetermined maximum level at higher engine speeds.
