On my latest project I was thinking of using and evaporative water tank for engine cooling. Just like the original Listers.
That project can be seen here ...

And warm up time can be controlled by the size of the tank.
I will most likely use a pump for circulation rather than rely on thermosyphon, although that simplicity appeals to me also.
My question to all those who use an evaporation tank:...
Do you mix glycol to the water in your systems ?
And if so, does the glycol boil off with the water or does the mixture get slightly more concentrated as steam leaves the system?
