[V8] cooling troubleshooting & temp sensors

Is there a way to diagnose viscous fan clutch failure?  Just watch as the engine speed is increased?
   
  My recollection of the majority of V8 overheating threads is that the solution lies with radiator replacement with an OEM radiator, not some aftermarket item.

mechanism I became aware of for the V8Q was a failure of the viscous clutch
that drives the cooling fan ... not sure I'd immediately jump to testing
sensors as on the V8 the electric cooling fan is almost a secondary
mechanism ...
