I kind of thought that a little too as I read it. I mean, after all, they are going to do and say everything to push their product. However, from a scientific standpoint, what they are saying does make sense. I never really bought into the thought that you had to SLOW the flow down through the radiator to give the water time to properly lose its heat. That means that the water is also flowing slower through the hot engine, and that would only allow the water to get hotter. The basic laws of Thermodynamics are only going to allow water to absorb so much heat before boiling, even with a pressurized system and antifreeze. Overall, I have to agree with the article.
