Royal Purple 01600 Coolant Additive, Purple Ice, Treats 20 Quarts, 12 oz., Pack of 4. Purple Ice radiator coolant by Royal Purple is a high performance synthetic additive for your radiator that will reduce engine heat by reducing the surface tension of the fluids in your cooling system. This enables improved heat transfer, optimum coolant flow, and helps to prevent the formation scale deposits in your radiator. It will also help to lubricate the seals in your water pump. One bottle will treat three to five gallons. It is ideal for use in straight water racing applications or in antifreeze/water mixtures. Royal Purple’s Purple Ice is compatible with most ethylene glycol antifreezes (green) and GM Dex-Cool coolants.Notes: Purple Ice should not be used in new radiators until anti-freeze has been cycled through the system.
