Greetings,

What is everyone using for coolant?   Is anyone using Redline Water Wetter?   There was some speculation on the RX-7 Club site that it might damage the water seals, though lots of people use it, and no one has been able to cite a single case of damage.  It certainly looks like the best cooling solution would be to use distilled water, and water wetter.  I can do that for at least 9 months of the year, but would need some minimal freezing protection a few months.   Eventually, maybe I can reach a compromise with just enough antifreeze to prevent freezing.  Cheers,

Rusty
