I keep about 75 water 25 coolant in summer and 50/50 in winter. Water will evaporate a bit, but remember its a closed system..it shouldnt empty out once a week.

your motor will atually run a few degrees cooler with straight water. the chemicals in the antifreeze make it run hotter. water will be fine as long as you remember to change it over before winter

I'd use a 50/50 mixture, antifreee/coolant serves two purposes, it lowers your engine coolants freezing point and raises its boiling point. I'd pressure test the cooling sytem, I don't think enough would evaporate using plain water to cause you a problem.

I run straight water with some redline water wetter. I agree with masshole it shouldn't be disappearing at that rate.

If you have coolant dropping, but no visible leak, it could be going out the tailpipes.

you should also run antifreeze because it protects against corrosion. a 25/75 mix is fine for summer and will greatly raise the boiling point of the coolant

Pure water cools better than anti-freeze. But it also has a lower boiling point than a mixture. It does not lube the water pump, and will corrode the system something awefull. Imagine soaking a bare engine block in water for a year. Unless you're on the track only, don't use pure water.

Surfactents like water wetter and blue ice will help a lot. But they don't lube the water pump or prevent corrsion either.
