Fan Viscous Hub

This is a replacement viscous fan hub.

Jimnys suffer from overheating and a common failure point is the fan hub. It gradually loses is viscous capability and therefore does not cool the engine at high temperatures.

A simple test is to get the engine nice and hot and the stick a rolled up newspaper into the fan. If the fan stops then the hub has failed. If the fan shreds the paper, your fingers and then your arm it is working properly.
