Polyorganic Acid Technology Extended Life Coolant 50/50 Yellow

POAT ELC 50/50 Coolant Yellow is a ready-to-use, extended-life antifreeze/coolant formulated with advanced Polyorganic Acid Technology (POAT), designed to offer superior corrosion resistance and thermal stability for gasoline and diesel engines. This 50/50 blend of ethylene glycol and deionized water delivers excellent freeze protection, efficient heat transfer, and boil-over resistance. The phosphate-, silicate-, nitrate-, and amine-free formulation protects critical cooling system metals—such as aluminum, steel, copper, brass, and cast iron—from rust, corrosion, and scale buildup. The bright yellow color allows for easy fluid identification and leak detection. Engineered for extended service intervals up to 600,000 miles or 6 years, POAT ELC 50/50 Coolant Yellow reduces maintenance requirements and supports reliable engine operation in commercial fleets and heavy-duty equipment.
