@tarphenry , I did a test on a Toyota Hilux for the viscous fan.
You can do this with someone in the bus, engine warmed up properly.
Stop the engine, hold the fan still with a bundled rag, have the engine started and ran at say 2000 rpm. As the engine starts to require the fan you can can feel the clutch start to grab gently at first and then more aggressively. It'll eventually become obvious to let it go. Then it'll roar into action and settle when finished with.

BACK TO THE PLOT- After further testing, I can prove that it is in fact the FAN !!! it passes the newspaper test with flying colours but when it reaches a certain point it becomes easier to turn thus stopping it cooling the water. when you stop the car and allow it to cool a little the fan starts to work again. I ran the car without the fan attached and the the rad was hot top to bottom so the pump and stat are functioning correctly. I like it when a plan comes together
I have sent you a PM. As you have now proved it's the viscous fan, my mod will work fine to replace it.
 
Don't know. Mine was registered 1995 but when I went into the main dealer they told me it was a '96 spec car, so they were building the 96 spec car a year earlier in 1995. Work that out!
Standard practice to start building a revamped vehicle some months ahead of release to build up stock.
