SEAOIL COOLANT is an extended long-life premixed engine coolant formulated using ethylene glycol and deionized water designed to provide reliable cooling system protection for modern automotive engines. The formulation provides effective protection against overheating, boil-over, freezing, rust, corrosion, and scale formation while maintaining stable cooling system performance under varying operating conditions. It is engineered to protect critical cooling system components including aluminum radiators, water pumps, thermostats, water jackets, and rubber seals.
