All the series i race in do not allow antifreeze so distilled water and one bottle of water wetter do the trick for me !

should I run water wetter in my LS7?

Without coolant I'd suggest checking your ph pretty often, or even with coolant if it's a few years old. Distilled water is IMO going to quickly become corrosive in the cooling system environment . Water wetter should help raise the ph, but there is not a lot of it and so it cannot push the ph as high or buffer as well as a gallon or two of coolant. Water wetter and distilled water might be more stable ph-wise than coolant, but I would not bet on it and ph test strips are only $8 or so.

water will eat the aluminum in heads pretty well unless you use a corrosion inhibitor. I've seen a lot of Mercedes heads with the coolant passages eaten so badly that they couldn't seal the head gasket..and the head was junk. Keep an eye on the PH if you want to run straight water..Probably OK for a track car, where everything gets drained pretty frequently, but not on a daily driver..Just my 2 cents

yep. watch the pH or change it every couple years.

water wetter works by lowering the surface tension so the nucleate boiling bubbles are smaller and works best when you coolant mixture is less than 50/50.

one mans experience with a similar blue antifreeze mix coolant additives
