Since 1930, coolant has been based on a mixture of ethylene glycol, water, and corrosion inhibitors. Jack Evans spent years researching the optimization of cooling systems. After realizing that a water-based mixture has various physical and chemical properties that limit engine performance and reliability, he finally developed a synthetic coolant in 1993.

Because Hawk coolant is not water-based, it consequently avoids all the problems of conventional coolant. Hawk coolant improves the cooling performance of your cooling system, protects the engine, extends its lifespan, and increases engine reliability.

Hawk coolant has been used for over 20 years by racing teams, in classic cars, as well as trucks, construction equipment, and aircraft. Long-term experience has confirmed that a single application of Hawk coolant eliminates the need for further changes throughout the engine's lifespan.
