The Royal Purple Purple Ice Radiator Super Coolant Radiator Additive 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. Its advanced technology reduces surface tension of the coolant providing improved wetting at critical liquid-to-metal interfaces throughout the cylinder heads and engine block. Purple Ice provides corrosion protection, for all type of coolant. It helps to prevent the formation of scale deposits in the radiator for optimum coolant flow, and it lubricates the water pump seals.


Note: Purple Ice should always be used in conjunction with antifreeze in regions where freezing temperatures occur. Compatible with traditional ethylene glycol antifreeze (green) and GM Dex-Cool® antifreeze.



Performance Advantages:

  • 2-in-1 corrosion inhibitor and wetting agent,
    enhanced protection of aluminum

  • Reduces surface tension of a coolant allowing more heat
    to transfer outside the radiator resulting in more horsepower

  • Fewer hot spots in the engine and cylinder heads,
    reducing the possibility of failure of critical engine components

  • Maintains a cleaner system, prevents overheating, and
    extends the life of the water pump

  • Safe to use with water-only or anti-freeze/water blends


Recommended Treat Rate:*

  • For use with antifreeze:
    1 oz. / quart of cooling system capacity

  • For straight water applications:
    1.5 oz. / quart of cooling system capacity

  • *Minimum of 20% antifreeze is recommended in street driven vehicles.


Test Results:

Extensive testing confirms Purple Ice reduces coolant temperatures better than comparable products while providing extra corrosion protection. For example, the average operating temperature of a 350 c.i.d. V8 engine (equipped with 160° thermostat) when dyno-tested with different coolants are:
