Water Wetter is a good product but it isn't going to solve your problem. Water Wetter isn't a problem solver, it is just a good idea that helps the coolant work a little better. I run 100% water in my Duster with a bottle of water wetter and the car runs cool but it isn't because of the Water Wetter, it is because is has a good radiator and a shroud and a big fan and the correct pulley ratio and all that other stuff.
