It depends on where you live and the temperatures expected as to whether or not you need antifreeze for freeze protection. Plain water has better heat transfer than ethylene glycol so if you don't encounter freezing conditions, water is preferred. However distilled water is a poor choice, deionized water would be preferable.

If you require antifreeze, do NOT use the extended cycle (usually red) stuff, it's inhibitor system is primarily aimed at aluminum radiators and blocks - go with the old traditional inorganic corrosion inhibitor package stuff - usually green. I generally find PEAK brand to be readily available.
