If not, what changes can be made for it to proprely work in these cold conditions?

Our membership is in the main UK based, and the UK doesn't experience temperatures anywhere as low as -50 degrees celcius.

Would have thought your best advice may be from your country's official Toyota importer or converters who specialise in adapting vehicles to these extremes. An example is Arctic Trucks - www.arctictrucks.com - who converted the Toyota vehicles used in the Top Gear Polar Special.

4.5 diesel??? I would suggest petrol, diesel will freeze

Yes you can run a diesel at -50C. I have done it. But as said diesel starts to wax at 0C. The fuel on the pumps in Canada and Alaska was a gasoline/diesel mix. The VDJ will most likely not run on this, my old KZ ran, but badly, additives helped. I also had a heated fuel line fitted. Modern diesel engines are much fussier and I think you will have issues.

That said manufacturers test their vehicles and engines down to very low temperatures and they run without issue. It will depend on the quality of the fuel.

You will also need to find coolant suitable for this temp which is possible in the UK but difficult. I was supplied some by Rock Oil.
