Heavy Duty Extended Life Coolant 100% Green

Heavy Duty Extended Life Coolant 100% Green is a concentrated, ethylene glycol-based antifreeze/coolant engineered for use in heavy-duty diesel and gasoline engines. Formulated with advanced Organic Acid Technology (OAT), it provides exceptional long-term protection against corrosion, scale, rust, and pitting for all key cooling system metals, including aluminum, steel, copper, brass, and cast iron. Free from phosphates, silicates, amines, and nitrites, this low-maintenance coolant supports extended service intervals—up to 1,000,000 miles or 20,000 hours with proper monitoring. As a 100% concentrate, it can be diluted to meet specific freeze protection requirements. The green color provides clear fluid identification and assists with leak detection. Heavy Duty Extended Life Coolant 100% Green is ideal for commercial fleets, off-road equipment, and mixed-engine environments requiring reliable, long-term coolant performance.
