Royal Purple Purple Ice Radiator Super Coolant Additive

Purple Ice is a high performance, synthetic, radiator coolant additive. It reduces engine heat by reducing the surface tension of the radiator fluids for improved heat transfer. Purple Ice also helps to prevent the formation of scale deposits in the radiator for optimum coolant flow, and it lubricates the water pump seals. Purple Ice should always be used in conjunction with antifreeze in regions where freezing temperatures occur. Purple Ice is compatible with traditional ethylene glycol antifreeze (green) and GM Dex-Cool® antifreeze. Note: Purple Ice should not be used in new radiators until anti-freeze has been cycled through the system.
