STAY COOL UNDER PRESSURE

To help maintain optimal operating temperatures of the available Duramax® 6.6L Turbo-Diesel V8 engine, a massive 28" variable-speed cooling fan was added. Dense, cool air from the Dual Path Air Induction System is drawn through both the hood scoop and the large grille to maximize horsepower and help optimize trailering performance. The factory-installed Diesel After-Run feature is designed to help cool down the engine following heavy usage.
