RACECOOL is a specifically formulated for todayfts high performance applications, including aluminum cooling an engine components. Not everyone is not a RACER or a HOT RODDER, the family van and drive to work cars donftt typically need better heat transfer like a high performance Engine. So RACECOOL is not for the average driver or the average engine. It is for the racer and hot rodder. It is designed not as antifreeze but rather a high performance coolant. Its primary purpose is to extract heat while protecting metals. RACECOOL has a pH of 10.5 and is a phosphate free low silicate formulation providing the best protection against aluminum degradation. RACECOOL has also completed extensive ASTM testing at Amalgatech laboratories which includes ASTM-D 1384 glassware test , ASTM-D 2908 water pump see water pump and ASTM-D 3306. By doing this accredited laboratory testing, as well as real world applications, we believe RACECOOL is absolutely the best high performance raceready coolant available to racers and riders.
