Cummins Filtration says its Fleetguard ES Compleat Glycerin heavy-duty engine antifreeze/coolant uses nontoxic glycerin in lieu of traditional ethylene glycol or propylene glycol. Glycerin is derived from renewable sources and is the primary byproduct of the biodiesel manufacturing process. The new formula also meets or exceeds the performance specifications of all heavy-duty engine OEMs, including Cummins CES 14603, according to the company.

With extended service intervals of 150,000 miles (250,000 km or 4,000 hrs), ES Compleat Glycerin is formulated to offer freeze protection to -32 degrees Fahrenheit, as well as liner pitting, corrosion, aluminum and solder protection for longer system life. Cummins Filtration says the coolant is compatible with gaskets, elastomers and other nonmetallics in the engine, and is suitable for all diesel, gasoline and natural gas engines.

The prediluted formula eliminates the need for mixing concentrated product with water, ensuring the cleanest solution enters the cooling system and reducing costly maintenance time, according to the company; and with Fleetguard coolant test strips and refractometers, field testing is quick and easy.
