Premium Purple Ice Super-Coolant - 12 oz.

Royal Purple's Purple Ice is a high-performance, synthetic radiator coolant additive designed to enhance the efficiency of water/glycol pressurized cooling systems. It reduces engine heat by lowering the surface tension of the radiator fluids, which improves heat transfer. The product also helps prevent the formation of scale deposits in the radiator, ensuring optimum coolant flow. Additionally, Purple Ice lubricates the water pump seals, providing additional protection.

Purple Ice should always be used in conjunction with antifreeze, especially in regions where freezing temperatures occur. It is compatible with all current OEM/factory and major brand automotive antifreeze, including traditional green ethylene glycols, as well as OAT/HOAT antifreezes (e.g., DexCool, Ford and Chrysler orange, gold, pink, European and Japanese OEM red, pink, etc.).

The advanced 2-in-1 corrosion inhibitor and wetting agent in Purple Ice provides year-round defense against corrosion, while also reducing the surface tension of the radiator coolant to help lower engine temperatures. Extensive testing has confirmed that Purple Ice outperforms comparable products in reducing coolant temperatures, while offering extra corrosion protection.

It is important to ensure that the cooling system is working properly and free of blockage and corrosion before using Purple Ice. Bottled, filtered drinking water is recommended, and distilled water should only be used when mixed with a minimum of 50% antifreeze.

When using Purple Ice with an antifreeze/water mix, the recommended dosage is 1 ounce per quart of cooling system capacity. For straight water (racing) applications, the recommended dosage is 2 ounces per quart of cooling system capacity. Purple Ice should be added once a year or every 30,000 miles (when used with antifreeze) or every 15,000 miles (when used in a straight water cooling system), whichever comes first, to maintain optimal performance.

It is important to note that Purple Ice does not provide freeze protection, and users should follow the manufacturer's recommendations when antifreeze is required. Additionally, if another brand of coolant additive has been used in the system, it is recommended to drain and flush the system before using Purple Ice.

Purple Ice is compatible with cooling system additives intended to stop or slow leaks, but users should be aware that such stop-leak products often coat the interior surfaces of the cooling system, potentially diminishing the effects of Purple Ice.

Purple Ice is suitable for use in diesel engines, where it can improve heat transfer and reduce cavitation. However, it should not be used with other heat-transfer or cooling-enhancing products or "water wetters." If such a product has been used in the cooling system, the system should be drained and flushed before using Purple Ice.

In summary, Royal Purple's Purple Ice is a high-performance radiator conditioner that optimizes coolant flow, reduces engine heat, and provides year-round corrosion protection for water/glycol pressurized cooling systems, including those in both gasoline and diesel engines.
