Hi, sound-barrier.

I'm not the brightest light bulb in the pack these days. This subject has been covered previously on RCU probably one hundred times. Unfortunately, today is not a good day for thinking or seeing for me. Perhaps someone will list a search string for us that will point sound-barrier in the proper direction for looking up antifreeze engine baths here on RCU. I would greatly appreciate it. TIA
