Interesting. Makes you wonder how the Evans got a reputation of being a go to product and better than antifreeze. Straight water has always been rated a better coolant than either but the downside is there is no rust or corrosion inhibitors. I know straight water does cause issues because I left some in the 47 for about a year and as you can see in the photo, managed to get quite a bit of rust started. That was a rebuilt engine which hadn't had water in it for years and was nice and clean before the water was left in. Another poster convinced me to go with a product called NoRosion. Must say the water didn't appear to be rusty when I looked the other day after almost another year.

NoRosion isn't recommended for aluminum radiators but a companion product called HyperKuhl which performs the same anti rust and corrosion function is.norosion.com/hyperkuhlcoolant.htm

It might be worthwhile to try the straight water with an inhibitor until it does get time for antifreeze and see how the car performs once you start driving it. IIRC, the 47 took about a bottle for the amount of water in the car.
