Pure water actually transfers heat better than a coolant mix.
Coolant provides good system corrosion protection and provides a good lubricant.
Coolant is also better to guard against freezing.
Water Wetter is a better choice if you don't need to worry about freezing.
Water with Water Wetter provides better cooling a lubricant and corrosion protection.
If you take your car to the track, you may also find that most tracks will not let you use coolant.
