Cummins Filtration has released its environmentally-friendly Fleetguard ES Compleat OAT (Organic Acid Technology) Coolant in a nitrite, amine and phosphate free formulation.


ES Compleat OAT does not contain borate or silicate, and it offers solid liner pitting protection and improved aluminum protection.

With extended service intervals of 300,000 miles, ES Compleat OAT offers freeze protection to -34 degrees and provides ultimate liner pitting, corrosion, aluminum and solder protection for longer system life. The coolant is compatible with gaskets, elastomers and other non-metallics in the engine and is suitable for all diesel, gasoline and natural gas engines.

According to tests conducted by Cummins, the NAP-free ES Compleat OAT coolant provides the anti-freeze, anti-boil, heat transfer and corrosion protection required of today's fully formulated, heavy-duty antifreeze/coolant. The new formulation meets ASTM and the performance specifications of most major OEMs including those for Cummins, Detroit Diesel, MAN, Volvo, MACK, and Navistar.

The coolant is available in both concentrated and premixed formulations. The premixed OAT formula eliminates the need for mixing concentrated product with water.
