If you do not want to go the water wetter route. Buy the Honda motorcycle brand of anifreeze and mix it up. It comes in a small container and is silicate free. Some say silicate free is the way to go and others who have used the car antifreeze say it does not matter. I guess the silicates are like an abrasive to the water pump seals. I bought the Honda stuff because I did not need a large container sitting around and I did not need another issue to handle.
