Description
Heavy-Duty Antifreeze/Coolant Concentrate – Green
This heavy-duty antifreeze/coolant concentrate is a non-silicate, non-phosphate formulation designed to deliver reliable protection for both light- and heavy-duty cooling systems. It contains an initial charge of supplemental coolant additives (SCA) and a minimum of 2400 ppm Nitrite (as NO₂) to help prevent cavitation erosion and corrosion, especially in water pumps and wet sleeve cylinder liners.
Formulated with a high-performance inhibitor system, this product protects all common cooling system metals and components. Its glycol base, combined with corrosion inhibitors and dispersants, provides year-round protection against freeze-ups, boil-overs, scaling, and engine corrosion. The formula also helps manage minor oil contamination and will not harm automotive finishes or rubber parts.
This coolant is intended for use in a wide range of applications, including passenger cars, SUVs, light trucks, and heavy-duty diesel engines. For optimal performance, follow the manufacturer’s recommendations and implement regular coolant monitoring practices.
Pack Size: 55 Gallon Drum
