Royal Purple Purple Ice Cooling System Optimizer - 12oz

This 12oz bottle of Royal Purple Purple Ice is a radiator conditioner that uses an advanced 2-in-1 formula. It works as both a corrosion inhibitor and a wetting agent, giving you year-round protection against rust and other corrosive elements in your cooling system.

The wetting agent is key here; it works to reduce the surface tension of your coolant. Lower surface tension means the coolant can spread more easily and make better contact with the hot metal surfaces inside your engine and radiator. This improved contact helps to transfer heat away more efficiently, which can lead to lower overall engine temperatures. It’s a solid option for anyone looking to get a little more out of their cooling system’s performance.
