Liquid Heat Reducer
Purple Ice is a high-performance, synthetic radiator coolant additive. It cuts 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.
