Kool-It Radiator Flush is formulated with additives that circulate through the cooling system to remove scale, loosen rust, mineral deposits and combustion by-products from the coolant system and radiator of a car or truck. 

Radiators use coolants primarily containing anti-freeze & water. Water contains minerals that form deposits over time on the metal surfaces of your cooling system and radiator. These deposits will reduce the heat transfer rate (which can cause overheating), the deposits also can cause corrosion of the coolant system components and reduce the efficiency and life of the anti-freeze. 

The longer you drive your vehicle without flushing the radiator and replacing the coolant, the more likely that cooling system problems will arise. Extreme driving conditions, such as; operation in hot climates, extended service intervals, stop and go driving, operation in mountainous areas, speeds above 65 mph, towing, etc., increases the chances of harmful deposit formation in the cooling system.
