NASHVILLE, TN – Cummins Filtration has released its Fleetguard ES Compleat Glycerin, a heavy-duty engine antifreeze/coolant that uses non-toxic glycerin in lieu of traditional ethylene glycol (EG) or propylene glycol (PG), according to www.businesswire.com. Glycerin is derived from renewable sources and is the primary byproduct of the biodiesel manufacturing process.


Cummins Filtration conducted extensive testing and field trials to approve glycerin as the base for this new coolant. All tests confirmed that ES Compleat Glycerin prediluted coolant provides the anti-freeze, anti-boil, heat transfer, and corrosion protection required of today’s fully formulated, heavy-duty antifreeze/coolant. The new formula also meets or exceeds the performance specifications of all heavy-duty engine OEMs, including Cummins CES 14603 (refer to AEB 99.01).

With extended service intervals of 150,000 miles (250,000 km or 4000 hrs), ES Compleat Glycerin offers freeze protection to -32 degrees F and offers 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.

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. And with specially designed Fleetguard coolant test strips and refractometers, field testing is quick and easy. Fleetguard ES Compleat Glycerin prediluted coolant extends service intervals, reducing maintenance time.

Cummins recently received an Eye on Innovation Award from the National Biodiesel Board for the company’s efforts to provide customers with guidance on how to use B-20 successfully and for work in supporting the assurance of biodiesel quality.
