Ol' Red Racing Coolant has a boiling point up to 260 degrees Fahrenheit (126.6 Celsius) under 15psi and freezing point down to -30 degrees Fahrenheit (-34.4 Celsius). The additives reduce surface friction in the closed loop cooling system allowing the engine to run cooler. This helps to reduce internal engine wear maintaining more horsepower and extended life. Meets or exceeds all industry performance standards of ASTM-D-52116, is virtually non-toxic, phosphate free and safer for the environment. PROUDLY MADE IN THE USA!
