A 1928 Chev 4 Cooling System that only needs topping up every 6 months

How many Chev 4's do you know that maintain this water level, before, during and after a 200 kilometer drive at speeds of up to 45 mph?

How many Chev 4's do you know that only needs a coolant top up every 6 months?

How many Chev 4's do you know that can run modern coolant, which is normally corrosive to a vintage cooling system?

I only know of 2 myself, Monty the 1928 Chev from Trafalgar, and the Red Chev from The Basin.

If your interested in how this was made possible, please open the 2 links below to dedicated postings on my blog.
