1. 210F is warm, but not unreasonable. If it gets above that I would be worried, but I wouldn't be worried if it stays there.

2. Water Wetter works. No brainer.

3. Don't run anti-freeze. As you may remember from chemistry class, impurities lower the boiling point of water and alcohol in anti-freeze boiler much sooner. Anti-freeze is just to keep the water from freezing. To avoid boiling, run straight water. (So why does water wetter work, you ask? Smart cookie. Water wetter does lower the boiling point since it is an impurity, but it uses larger molecules to carry more heat away from the engine. The net result is that it still boils sooner, but it keeps the car cooler in the first place.)
