U1P-Cool UltraCool OAT Antifreeze + Coolant is an ethylene glycol-based coolant utilizing Organic Acid Technology (OAT). It features extended life corrosion inhibitors derived from organic acids, providing maximum protection against rust and corrosion in engine cooling systems. This formulation is free from nitrite, amine, phosphate, and silicate (NAPS Free) and does not contain 2EH acid or any other organic acid that could be aggressive to hoses and gaskets. With proper maintenance, UltraCool OAT Antifreeze + Coolant guarantees protection for up to 1,000,000 miles or 10 years, whichever comes first, and does not require Supplemental Coolant Additives (SCAs) due to the high stability and slow depletion of its organic corrosion inhibitors. UltraCool is suitable for use in modern heavy-duty diesel engines. For optimum performance Antifreeze + Coolant concentration should be maintained between 40-60% by volume.
