Duramax Engines Is Built To Last Longer

The Duramax Engines feature an integral oil cooler which is somewhat similar to those found on various other medium-duty engines in pickup trucks. However, the Duramax Engines' cooler is not located in the end-tank of the radiator as is the usual design procedure. The integral oil cooler on the Duramax Engines is physically mounted onto one of the sides of the block. This position allows all of the coolant liquid flowing from the water pump to be channelled through the Duramax Engines' integral oil cooler prior to it passing through the hot motor. The result of this unique configuration is that the cooling of the oil is increased and so is the Duramax Engines' life expectancy.

Duramax Engine Has An Innovating Cooling System

The Duramax Engine features a cooling system which sprays motor oil directly onto the piston itself. This feature of the Duramax Engines is completely innovative and reflects General Motors' commitment to ongoing Duramax Engines' engineering innovation, research, and development. The oil spray is directed towards the rear of the piston bowl on the Duramax Engines. This oil spraying allows added cooling capabilities to the piston and is designed to add durability and reliability and many years of extra life to the Duramax Engine Turbocharged V8 Diesel pickup truck.

Diesel Duramax Engine Features An Allison 1000 Tranny

The Diesel Duramax Engine also has a transmission oil cooler which, when employed in conjunction with the five-speed automatic Allison 1000 transmission, becomes mounted in a position below the main radiator of the Duramax Engines. This transmission oil cooler is able to prevent excess heat from the transmission mechanism being transmitted into the cooling system of the Duramax Engines directly. The transmission oil cooler takes in air from front bumper openings in the Diesel Duramax Engine, especially at speed.

Diesel Engine Duramax Has A Transmission Oil Cooler

The transmission oil cooler was made considerably larger in the Diesel Engine Duramax than in previous General Motors diesels. For example, previous General Motor diesels utilized 3/8 inch lines while the Duramax Engines' transmission oil cooler uses 5/8 inch lines. The fluid flow rate has also been increased in the Duramax Engines. The Duramax Engines' transmission oil cooler is able to flow a total of 6 gallons per minute of transmission fluid. Due to this much greater flow rate the cooling of the transmission fluid is far more efficient than in previous engines prior to the Diesel Engine Duramax.

Duramax Diesel Engine Has A Heavy Duty 21 Inch Fan

The Duramax Diesel Engine also features a 21 inch diameter fan made of composite elements. This feature of the Duramax Engines was meticulously engineered to provide ample cooling in the roughest and hottest of operating conditions for the Duramax Engines. This Duramax Engines fan is mounted inside a fan shroud made of two separate pieces and has a greater capacity modulated clutch than previous diesel engines from General Motors Corporation developed and manufactured prior to the Duramax Diesel Engine.

Duramax Diesel Engines Are Extraordinarily Rugged

It is obvious that a larger fan is able to direct a greater volume of air through the main engine coolant radiator in order to keep the entire powertrain cooler in the Duramax Diesel Engines. The larger sized modulating clutch for the Duramax Engines' fan is designed to minimize the noise from the fan, and the fan shroud which is set up in two pieces is able to be opened up so that service technicians may easily access the area in the Duramax Diesel Engines. All of these are factors which add up to one rugged diesel engine family, the GM Duramax Engines!
