So my NM 3.2 overheated yesterday. It only took a few hundred metres up a hill accelerating hard with an empty medium weight trailer on. I stopped as soon as I could safely.

With the motor stopped I could spin the fan freely.

Time for viscous clutch attention??

I'm sorry for the late reply. I only used one tube of 18ml Toyota oil and I can confirm that my viscous coupler is working as good as ever.

Certainly if it was spinning freely, and was certainly warm enough to be resistant to spin, absolutely try Chris's excellent instructions on how to reco it. Other wise buy a new one, shop around you will get one for under $300. At the same time double check all the other key elements to the cooling system.

The visco should not free spin when the engine is up to temp, in fact well before

Look at the videos I posted. If it's free spinning after switching the engine off (engine warm) the coupler needs servicing. The second video shows how the coupler should behave.

I tried to get the oil from Toyota yesterday and they had run out. So this morning I rang Mitsubishi, they told me that the unit could not be fixed and would have to be replaced. I got two tubes today from another Toyota place.

Another silly question. When the vehicle is at operating temperature and you are driving on a motorway at 100K should the fan be operating?

Next stupid question when the vehicle is at operating temperature and the motor off should you be able to turn the fan by hand?

Yes

and

Yes

When it is up to Op temp it is still possible to spin the fan by hand, your should notice it is more rigid than when it was first cold. It can be hard to pick this. The key is that when at Op temp and the engine is turned off you will see the fan stop instantly and not continue to rotate.
If you start the engine when cold and turn the engine off after say 30 or slightly more seconds of running a good fan will still pin less than 4 revolutions more.

If in doubt reco it or replace it. My old one behaved like the above so I thought it was some other part of the cooling system after replacing most other components with still no fix to the problem, I decided to tackle the visco and ended up replacing it and the problem was fixed.
