(6 pack) Royal Purple 01600 Purple Ice Super-Coolant Radiator Additive - 12 oz.

Antifreeze/Coolant Additive Purple Ice 12.00 oz Bottle Each Keeping it cool is one of the keys, and Royal Purple - Purple Ice is the king of cool. 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. When using Purple Ice with an antifreeze / water mix, Royal Purple recommends adding 1 ounce of Purple Ice per quart of cooling system capacity. For straight water (racing) applications, Royal Purple recommends adding 1.5 ounces of Purple Ice per quart of cooling system capacity.
