I ordered a bottle of water wetter, but haven't mixed it in yet. I guess I misinterpreted the rulebook language. When I read no combustible or flammable coolants, I assumed they were outlawing things like straight alcohol (why anyone would want to use straight alcohol as a coolant is a separate issue).
Right now, the inside of my radiator, block, and all hoses have been exposed to nothing but pure distilled water.
Is it the common interpretation of the rule that water wetter is not allowed?
Steve.
