Many years ago I couldn't afford antifreeze, and the worst fear was opening the cap on a radiator and it looking like tomato soup! There is no way I would BUY Dex Cool that looks like tomato soup already, and pour it in my radiator. I've had nothing but great results using Prestone ethylene glycol and distilled water at 50/50 mix. I'm 62 now so I can't see changing anything at this late stage of the game.
