Waterless Engine Coolant
I had probably run across the subject sometime but.... I was watching Wheelers and Dealers and they used a chemical, to purge all traces, of water, rust etc, from the cooling system, of a TR6 and ins...

If it's EVANS which is the only waterless coolant I'm familiar with quite a few 7.3L owners switched over to it some years back. As mentioned it's a zero pressure coolant, HOWEVER, one thing to consider if it's the same formulation as it used to be it's basically a mixture of PG and EG coolants and it actually has less cooling capacity than the normal water/EG or water/PG mixtures since the main cooling capacity comes from the water in the coolant mixture and not the glycol component. It wasn't really an issue with the 7.3L engine since it had such a robust cooling system to start with, but other systems might not fair as well. This subtle fact is never discussed or documented for obvious reasons, but AFAIK it is in fact true. What to me knowledge that has never been thoroughly tested and documented is how much difference there actually is in the cooling capacity/effectiveness of the two systems.
As mentioned it can be a bear to get all the water out and one way IIRC was after filling your system was to drain it a couple of times and save the drain and cook it on your stove to remove more of the water and then refill. Quite a hassle, but it was important to do to get those last traces of water out.
Just something to consider if you're thinking of going this route.
