It doesn't take a gearhead to know that engine coolant is vitally important to the overall health of your car or truck. Still, thousands of vehicle owners ignore their coolant every year to the detriment of their precious powertrains. Prestone wanted to demonstrate just how important coolant is to the health of an engine, but this isn't the sexiest topic on earth. So did Prestone spend big bucks on a CGI simulation? How about boring us with a video showing how long it takes for a vehicle sans fluids to go up in smoke? Nope. Instead Prestone gave some well-trained pyromaniacs high-powered blow torches and melted the aluminum engine block of a General Motors 3.6-liter V6.

Hit the jump to watch as GM's high-feature V6 feels the heat of several blowtorches. It only took about 20 minutes to mutilate everything but the crankshaft and cylinder sleeves, but Prestone cut the carnage down to three manageable minutes.
