Engine Description
WARNING: This page is about a different variant/trim than selected.
The 6.0L diesel engine is:
- a four-cycle turbocharged V-8 with overhead valves.
- 6.0 liter (365 cubic inch) displacement.
- separated into two banks, the right bank numbered 1, 3, 5, 7 and the left bank numbered 2, 4, 6, 8.
- rated at 325 horsepower and 560 lb-ft torque
The cylinder block has been designed to withstand the loads of diesel operations by using:
- a two-piece crankcase.
- internal piston cooling oil jets.
- a forged steel crankshaft.
- powdered metal, fractured connecting rods.
The piston is:
- made of an aluminum alloy.
- fitted with an upper keystone compression ring.
- fitted with a lower rectangular compression ring.
- fitted with oil control rings.
The piston pins are:
- a free-floating type permitting the piston pin to move/float freely in the piston pin bore.
- retained in the piston-by-piston pin retainers.
The camshaft is:
- supported by five insert-type camshaft bearings.
- of the roller camshaft design.
- driven by the crankshaft through the use of the crankshaft gear and the camshaft gear.
The hydraulic valve tappets:
- minimize engine noise.
- maintain zero valve lash.
- incorporate camshaft follower guides.
- incorporate a roller follower design that reduces camshaft wear.
The cylinder heads are designed:
- to incorporate electrohydraulic fuel injectors.
- to locate the fuel injectors in the center of the combustion chambers between the rocker arms.
- with external high-pressure oil galleries.
The glow plug system is:
- designed to preheat the cylinders for faster cold weather starts and smoke reduction.
- controlled by the powertrain control module (PCM).
- mounted directly into the cylinder heads.
The optional block heater is:
- designed to heat the engine coolant and oil for improved cold weather starts.
- located near the starter.
- powered by a 120 volt external power source.
- replaceable, but not repairable.
The fuel injection system used on the engine:
- is controlled by the powertrain control module (PCM).
- utilizes a frame mounted electric fuel pump.
- circulates fuel through a combination fuel filter, fuel heater and water separator assembly.
- uses eight electrohydraulic fuel injectors.
The engine lubrication system:
- is divided into two systems: the low-pressure system lubricates the engine, the high-pressure system actuates the fuel injectors.
- is cooled by an engine oil cooler.
- utilizes an oil pressure sensor and an oil pressure regulator.
