In engineering you can break down systems to indiv components an analyze. I was just trying to explain. If folks don't get the principles and understand the thermodynamic laws then so be it. I think some are just talking past each other. Regardless, there was plenty of engineering that went into the cooling system if you want to use examples from other industries that do not apply to how a car works ok, but that doesn't mean that principle matter. My only point was you can raise flow higher to the point you short circuit the cooling and create hot spots in the block and even the radiator. Cavitation was an issue Chrysler worried about.
