Mack Defense and Phillips & Temro Industries (PTI) have partnered to prepare U.S. Army M917A3 heavy dump trucks for harsh cold temperatures, with an engine heating solution that allows the trucks to start and operate more efficiently and effectively in extreme cold weather.

When activated, the PTI engine heating system circulates warm coolant throughout the engine to provide even heat distribution. Thermostatically controlled heat distribution ensures fast starts for critical applications needed by the U.S. Army. Warming the coolant also reduces fuel consumption, emissions, and engine wear, all critical factors. When equipped with the PTI system, the M917A3 truck is designed to start in extreme temperatures as cold as -40°F and provides optimized cold start performance.
