What are Duramax Engines?

Duramax engines are configured in inline and V configurations and use 4, 6, or 8 cylinders. They were first sold and used in GMC trucks and diesel vehicles in 2001. Chevrolet also uses these engines in their diesel vehicles. Duramax engines are either simply turbocharged or both turbocharged and intercooled. (Source)

GMC Duramax engines are made of aluminum alloy so they are lightweight and don’t weigh the vehicle down and prevent acceleration. These engines have a complex Active Thermal Management system that allows coolant to flow through the necessary systems while still allowing other parts of the engine to warm up quickly when necessary. This makes this diesel engine more efficient than others. (Source)

Because of how these engines are configured and manufactured, the noise that it makes while running is minimal. However, this doesn’t mean that the engine has compromised power for less noise, as these engines are quite powerful and will allow you to accelerate quickly when in your GMC diesel truck.
