I now live in Vegas (which is way hotter in Florida) and a lot of mechanics and car enthusiasts here use more coolant than water. It's up to you. I was told by a radiator shop that vehicles that just add water are more prone to rust. One more thing, your water pump and other cooling components need the lubrication of the coolant. But it's up to you.
