Building on more than 112 years of heavy-duty truck and powertrain excellence, Mack is now introducing Bulldog-branded coolants.

“Bulldog coolants formulated to exacting Mack powertrain standards deliver the very best protection for our customers’ Mack equipment,” said David McKenna, director of powertrain sales and marketing of Mack Trucks. “Mack Bulldog Extended Life and Heavy-Duty coolants offer a lower cost of ownership while providing optimal operating performance.”

Mack Bulldog Extended Life (ELC) Coolant is a carboxylate-based, organic additive technology that contains nitrite and delivers a service life of 600,000 miles or 12,000 hours or 48 months, with no extender needed. It is silicate- and phosphate-free, and can be distinguished by its red color.

Mack Bulldog Heavy-Duty (HD) PF Coolant fully formulated, phosphate free coolant contains the first dose of supplemental coolant additives. It offers a service life of 300,000 miles or 6,000 hours or 24 months and has a purple or fuchsia color.

Mack Bulldog Coolants are designed for use in a wide variety of cooling system applications, including on-road, off-road and stationary engine applications, and vehicles fueled with gasoline, diesel and natural gas. They provide outstanding corrosion protection for aluminum, brass, cast iron, steel, solder and copper, and reduce hard water scale formation, according to the manufacturer.

Available as part of Mack’s integrated product offering, Mack Bulldog coolants were also developed to meet or exceed the requirements of the American Society for Testing and Materials (ASTM), Technology & Maintenance Council (TMC), and most other major engine and truck original equipment manufacturers. Mack Bulldog Extended Life Coolant also meets the Caterpillar EC-1 requirements.
