Mack Releases Proprietary Bulldog Coolants
Aug 30, 2012 1:14 PM
Mack Trucks has released two proprietary Bulldog-branded coolants—Mack Bulldog Extended Life (ELC) and Mack Bulldog Heavy-Duty PF—that are designed for use in a variety of cooling system applications, including on-road, off-road and stationary engine applications, and in vehicles fueled with gasoline, diesel and natural gas.
According to Mack, both coolants provide corrosion protection for aluminum, brass, cast iron, steel, solder and copper, and reduce hard-water scale formation.
“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 for Mack Trucks. “Mack Bulldog Extended Life and Heavy-Duty coolants offer a lower cost of ownership while providing optimal operating performance.”
The ELC coolant uses a carboxylate-based, organic additive technology that contains nitrite and delivers a service life of 600,000 mi. 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, the company said.
The PF coolant is a fully formulated, phosphate-free coolant that contains the first dose of supplemental coolant additives. It offers a service life of 300,000 mi. or 6,000 hours or 24 months and has a purple or fuchsia color.
Both coolants were developed to meet or exceed the requirements of the American Society for Testing and Materials (ASTM) (ASTM D6210 and ASTM D3306), Technology & Maintenance Council (TMC) (TMC RP329 and TMC RP351), and most other major engine and truck original equipment manufacturers.
The Mack Bulldog Extended Life coolant also meets the Caterpillar EC-1 requirements.
