Coolant Additive

KOOL-IT Supreme Coolant Treatment is chemically engineered to reduce the surface tension of a 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.

We formulate Cool Down™ coolant additive not just for gasoline engines. It also works great as a diesel coolant additive. It improves the performance of coolant and is safe for all radiator systems. It's ideal for racing, street, RV and tow vehicle applications.
