How to Check and Replace the Engine Cooling Fan Viscous Coupling

[@Carmafixcars]

It's probably just safer to check the condition of the viscous coupling with the engine off as shown here, if it's easy to spin by hand then it's no good, if it's hard to spin by hand then it's probably good. I wouldn't put my hand in there when the engine is running because it may still catch suddenly. Good video and description of this contraption.
