This is my experience so far using Evan"s waterless coolant in another collector car. Cast iron block, aluminum radiator, silicone hoses ( a modified classic morris mini pickup). Stuff was not cheap (about $52.00/gal), although the mini only uses a couple gallons. They want you to ideally have NO water in your cooling system(but you can have 3%). I was dealing with a freshly rebuilt motor, new radiator, hoses and heater core, so no problem there. It seemed to work like penetrating oil in finding any small leak, but again I was dealing with a fresh rebuild, so I might of had those leaks anyway. It runs a little hotter (10 degrees F maybe). Now for the good--No water therefore no pressure buildup from steam. You could run a system like our cars have and not have to worry about boiling over (stuff boils at 325 degrees F--if you're there you already have problems). Never needs changing, will not promote rusting (great for our cars that might sit a long time between uses). So far I'm pleased but it is kind of a pain to get going (prep and $) Ross
