                                                     Duramax Power Diesel Turbo Vane  The Duramax diesel turbocharger increases engine power by pumping compressed air into the combustion chambers, allowing a greater quantity of fuel to com-bust at the optimal air or fuel ratio. The duramax 4094 vvt turbine spins as exhaust gas flows out of the engine and over the exhaust turbine blades, and turns the air intake compressor wheel at the other end of the turbine shaft, pumping more air into the intercooler intake system. The engine control module controls nine vanes for the turbocharger. The vanes are used to vary the amount of boost pressure and can control the boost pressure independent of engine speed. The vanes mount to a unison ring which are rotated to change the vane angle. The engine computer will vary the vane angle ...

                   Cummins Diesel Truck Can Be Equipped With Two Fuel Injection Pumps  The drive belt system may use 1 belt or 2 belts. The drive belt is thin so that it can bend backwards and has several ribs to match the grooves in the pulleys. The drive belts are made of different types of rubbers, chloroprene or EPDM, and have different layers or plays containing either fiber cloth or cords for reinforcement. Both sides of the drive belt may be used to drive the different accessory drive components. When the back side of the drive belt is used to drive a pulley, the pulley is smooth. The drive belt is pulled by the crankshaft balance pulley across the accessory drive component pulleys. The spring loaded drive belt tension-er keeps constant tension on the drive belt to prevent the drive belt from slipping. The drive belt tension-er arm will move when...

                         DIESEL GEAR TOUCH CONTROL FOR 2001-2005 GM/CHEVY DURAMAX                                                                        TOW/HAUL MODE PURPOSE - It is important to note that the customer may accidentally engage the tow/haul button and then comment about delayed or harsh shifts when not pulling a trailer or under heavy load. This is a Normal function of tow/haul mode when used in inappropriate conditions That may contribute to complaints that "cannot duplicate/no trouble found." - Tow /Haul is a mode that will optimize gear selection for operation with heavy loads (such as towing): 1. Optimize acceleration performance for launches and rolling accelerations 2. It reduce shift cycling 3. Opt...

                                                    Cold Weather Starts and Glow Plugs  Glow Plug System Description Duramax diesel engine, air alone is compressed in the cylinder. Then, after the air has been compressed, a charge of fuel is sprayed into the cylinder and ignition occurs, due to the heat of compression. Eight glow plugs are used as an aid to starting. The glow plug initial ON time will vary based on the system voltage and temperature. Lower temperatures cause longer ON times all the times. The ECM provides glow plug operation after starting a cold engine. This post-start operation is initiated when the ignition switch  is returned to Run, from the Start position. This operation helps clean up excessive white smoke or poor idle quality after starting. Control of the instant start system, glow plugs is determine...

My Duramax Diesel Leaks Oil  Measurement of Oil Consumption Engines require a period of time to BREAK IN so that moving parts are properly seated. Therefore, oil economy should not be tested until the vehicle has accumulated at least 6400 km (4000 mi). An exception would be allowed only if an engine is reported to be using more than 0.946 liter (1 qt) in 1600 km (1000 mi). 1. Verify that the engine has no external leaks. Repair as necessary. 2. Verify that the engine is at normal operating temperature (see Owner's Manual or Service Manual). 3. Park the vehicle on a level surface. 4. Wait at least 15 minutes, after the engine is shut off, before checking the oil level to make sure that the oil has had time to drain back into the crankcase. 5. Verify that the oil level is at, but not above, the full mark on the dipstick, and that the proper viscosity and quality oil are being used as recommended in the Owner's Manual. 6. Record the vehicle mileage, d...

                              Duramax Diesel New Cylinder Head Gasket Assembly Cleaning  Special Cleaning Requirements For 2001-2006 vehicles produced with the first generation head gasket, special attention must be given to the cleaning of the engine block and cylinder head surfaces when servicing with a second generation gasket. The crimped areas (1) on the first generation gasket may, over time, allow corrosion buildup where they contact the block and cylinder head surfaces. The second generation gasket has raised ribs that seal at these crimped areas (1). A special cleaning procedure is required to ensure proper sealing. Cleaning Procedure 1. Remove the old head gasket using service manual procedures. Save the gasket for reference until the repair is completed. 2. Place clean rags in the cylinder bores and push-rod openings in order to keep out debris. 3. Carefully clean the gasket ...
