OPTIMIZED ENGINE PERFORMANCE

Engineers worked to make this already powerful engine perform more efficiently by optimizing its cooling capacity by way of a large radiator and fan and improving the air induction system.

  • The dual-path intake system draws dense, cool air to enhance performance
  • To help maintain optimal operating temperatures, the available Duramax Diesel features an integrated engine after-run cooling function
  • The integrated engine after-run cooling function can continue to idle the engine after extended and exhaustive periods of use and allows for proper cool-down of vital underhood components

STAY COOL UNDER PRESSURE

  • Dense, cool air from the Dual Path Air Induction System is drawn through the hood scoop and the large grille to help optimize horsepower trailering performance
  • A 28" variable-speed cooling fan helps maintain optimal operating temperatures of the available 6.6L Duramax Turbo-Diesel V8 Engine
  • The factory-installed Diesel After-Run feature helps cool down the engine following heavy usage
