I've used this in my ford small block Capri and like it, but there are some things that you need to know.
It doesn't cool as well as water....pretty much nothing does, so you may run a little warmer, but given the boiling point of Evans is much higher, you have far more overhead, plus as has been said, no pressure. It's also flamamble, but then pretty sure anti freeze mix is as well. I'm going to try some and see exactly what flamable means.....readily catches on fire, or you have to be letting it drip on a red hot manifold. Finally, make sure all your hose connections are sound. This stuff finds it's way out of where water/ antifreeze would not.
Overal, I'm a fan. It's great for cars that sit around a lot, as the anti corrosive additives never fall out of solution, as can happen with regular anti freeze, plus should last indefinitely, but still can absorb water, so keep your cooling system sealed and keep any spare in a sealed container.
