The Royal Purple Ice Super Coolant is a coolant additive designed to reduce coolant temperatures. This combines a corrosion inhibitor, as well as a wetting agent that provides your vehicle with year-round defense against corrosion.
Tests show that when compared to competitive coolant additives, the Purple Ice reduces coolant temperatures more efficiently and effectively than other brands. With antifreeze, mix 1 ounce per quart of coolant. With water, use 2 ounces per quart.
