Fan assembly is is silly money too. Fan assembly + coupling genuine -£392 as set.
Some upgrade to 300TDI version viscous.

No sensor and no wire Tony.

I've already searched after we spoke about the first time around

@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.

Pre EGR hasn’t got the 3rd head sensor

The third sensor has nothing to do with aircon or my aircon fans mod.

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.

A diagnostic reading of the BECM will give the build date if you are ever up this way.

RangeRoller dt · Oct 13, 2019

There’s also a member here that can supply you the original build sheet but I mustnt mention his name.

Grrr knows him

A Vin decode can give a date of manufacture

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.

Yip, just cut the vacuum pipe out of site and it never opens. The ECU operates the electronic valve as it pleases but never draws the mechanical valve open. All looks official under the bonnet. Just don't function man!!
