Re: Engine Fan clutch operation Q.

1. The fan clutch is viscous material, that
2. As it heats up, it becomes more solid.
3. As it becomes solid, the fan turns with the engine.
4. Clutch Test, try to turn the fan with the engine off, and:[*] Engine Hot , the fan should not turn easily.[*] Engine Cold, the fan should spin easily
