Duramax Diesel History

The “Duramax” brand was coined by General Motors in 1996 as a variant of the company’s International diesel engine used to build the Navistar subsidiary. This brand is well known for being an industrial-strength truck manufactured with Class 8 trucks during the early 2000s. The original Duramax diesel engine was available in two configurations, depending on how it was ordered from an authorized GM dealer or fleet manager. The “DFI” configuration was installed on all applications using a mechanical injection pump providing sequential fuel injection which supplies fuel to each cylinder individually under an electronically controlled timing. On the other hand, “EFI” was installed on all applications using an electronically controlled fuel injection system. The Duramax EFI was added in 2001 which meant this type of vehicle saw a recent surge in sales.

Duramax Diesel Parts Used Today

Now, let’s start this post off with some basic information on what parts are based on the original Duramax engine. In order to establish a comparison baseline, we’ll use a 2013 Chevrolet Silverado 1500 LTZ equipped with an 8.1-liter Duramax V6 gasoline engine. Of course, this configuration will offer a powerful powertrain while being able to tow up to 8500 pounds while tugging up steep inclines and tight corners in mountain terrain.

The original Duramax is mainly composed of two blocks. The crankshaft, connecting rod bearings, pistons, balancer shafts, and much more are all based on this type of engine. This will all be housed in a dry-sump lubrication system with three oil tanks offering 500 quarts of capacity each. That’s 2200 gallons of oil storage for this engine alone. The cooling system is equipped with thermostatically controlled radiator fans offering both increased cooling capacity and airflow to the engine increasing horsepower at higher RPMs increasing air intake/outtake capability for improved performance.
