Extreme Extended Life antifreeze/coolant by Zerex meets the Cummins CES 14603 and Caterpillar ECI specifications for heavy-duty applications without requiring supplemental silicate additives at first fill. The patented new formula protects against liner pitting and corrosion, hardwater scale, and other deposits.

“Add one bottle of Extreme Extended Life Extender at the 300,000-mile (or 7,000-hour mark), and you can go up to 600,000 miles (or 14,000 hours) without draining,” said Dave Turcotte, chief formulation engineer for Zerex. “It's compatible with other brands of ethylene glycol-based coolants, so therefore it can be used for mixed fleets with gasoline engines.”
