KOOL-IT® Supreme Coolant Treatment is chemically engineered to reduce the surface tension of coolant, thus allowing it to more deeply penetrate metal surfaces at vital heat-transfer areas. This decreases operating temperatures and significantly reduces the possibility of engine overheating. Due to its unique chemical composition, KOOL-IT is very effective in preventing damage from electrolysis, corrosion, and pitting. The overwhelming majority of failures associated with aluminum radiators found in most newer vehicles are due to corrosion. This corrosion is a result of deficient chemical protection within the coolant. KOOL-IT is the easiest and most cost effective way to protect a radiator or heater core (and prevent warranty claims) from declining and damage that can lead to system failure. Compatible with all types of antifreeze, Kool-It provides the type of total cooling system protection required for today's modern cars and trucks.
