Liquid Chill™ Synthetic Engine Coolant is designed to meet or exceed all stock specifications and exceeds the specs needed to pass ASTM D6210 and ASTM D3306 coolant tests. It's premixed with deionized water, so it's ready to use and safe for all water-cooled engines, protecting against boilover to 265°F and freezing to -26°F (with 15 psi cap)**.The proprietary formula doesn't contain any nasty nitrates, amines, high-fructose corn syrup, phosphates, silicates, borates, and all those other "ates" that will clog up thermostats and radiators, and cause excessive wear on water pumps. However, Mishimoto engineers strongly recommend that you and your children do NOT consume this coolant. Seriously, don't drink it, and keep it on a high shelf so kids and pets can't get to it.Now, by popular demand, we're offering Liquid Chill™ in convenient 64 oz. containers, so you can top your coolant off, quickly refill your dirtbike radiator, or just keep it around as a conversation piece.
