Since we're all fumbling about and not really answering the direct question, I'll toss in a few words: The purpose of antifreeze is to prevent freezing and to prevent boilover. It raises the boiling point to 230 degrees (or so) and lowers the freezing point to around -10, depending on the dilution used. It does not cause the engine to run cooler, but allows it to run hotter without damage. My mechanic demonstrated to me that antifreeze does a poorer job of dissipating heat than does plain water by dipping a red hot piece of steel into antifreeze to cool it, then doing the same with plaln water. What a surprise; a noticeable difference of cooling time. Now you know what I know. Karl Wolz
So is there any science to tell us that distilled water plus lubricant and wetter helps an engine stay cooler than a standard 50/50 antifreeze mix? KG6RCR |
