So Fix it

An engines firing order is the sequence that each cylinder is used in power delivery. The firing order for the 6.6L turbo diesel V8 in the 2004 Chevrolet Silverado 2500 2WD is 1-2-7-8-4-5-6-3.

Gasoline Versus Diesel

In a gasoline engine, the distributor or Engine Control Unit sends electricity to individual spark plugs to ignite fuel in each cylinder in a specific order. In a diesel engine it is determined by the order in which fuel is injected into each cylinder.

Cylinder 1

Engine firing orders always start with cylinder number one, which on this engine is located at the front left of the engine from the drivers point of view.

Cylinder Banks

GM V8 cylinders are numbered 1-3-5-7 on the left (drivers) side of the engine, and 2-4-6-8 on the right (passenger) side.

The Cummins B Series of engines are diesel engines for trucks and industrial applications. The six-cylinder, 5.9-liter version has appeared in Dodge Ram trucks since 1989. These engines are turbocharged and require an effective cooling system to prevent the engine from overheating. The water pump in a Cummins 5.9-liter diesel engine is on the front of the engine, below the cooling fan. The replacement of the water pump in this engine requires the removal of additional components.

Instructions

1

Remove the cable from the negative terminal of both batteries with a socket wrench. Place a drain pan under the radiator drain and remove the drain plug. Wait for the coolant to drain from the radiator and replace the drain plug.

2

Detach the electrical connectors from the air temperature sensor and the mass airflow sensor if your vehicle is so equipped. Detach the inlet tube for the turbocharger and remove the housing for the air filter with a socket wrench. Remove the alternator assembly.

3

Rotate the tensioner assembly clockwise with a long-handled wrench to relieve the tension on the accessory drive belt, then disconnect the belt. Remove the mounting bolts for the water pump with a socket wrench and disconnect the water pump from the engine. Remove and discard the O-ring from the water pump.

4

Install a new O-ring onto its mounting groove on the water pump. Install the water pump so that the weep hole on the water pump faces down. Torque the mounting bolts for the water pump to 18 foot-pounds with a torque wrench.

5

Install the accessory drive belt with a long-handled wrench. Connect the alternator assembly and torque its mounting bolts to 30 foot-pounds with a torque wrench. Install the air filter housing and attach the inlet tube for the turbocharger. Attach the electrical connectors to the air temperature sensor and mass airflow sensor.

6

Refill the radiator with coolant and connect the cables to the negative battery terminals with a socket wrench. Start the engine and allow it to warm up. Check and correct any coolant leaks.

Repairing a 2001 Dodge Ram 2500 equipped with the 5.9 liter Cummins diesel motor may be simple or difficult, depending on the required repairs. The 5.9 liter, 24-valve Cummins diesel was available in model years 1998 through 2002 before being replaced with a common rail injection system. Many repairs may be completed by a do-it-yourself owner, while others should be performed by a professional mechanic. The first step in repairing your Dodge 2500 is to identify the problem and all affected parts.

Instructions

1

Diagnose the issue with the Ram by evaluating the pickups performance and referring to the manufacturers auto repair guide. Stalling, slow throttle response or lack of power may indicate an issue with the fuel systems or turbo charger. Trouble shifting could mean a transmission problem. The 2001 Dodge Ram 2500 is also equipped with a data port located underneath of the dash board on the drivers side. Plug a code reader, available at most auto parts stores or through a professional mechanic, into the port and read any codes that may indicate issues with one or more of the trucks operating systems.

2

Identify the components and parts that operate the affected systems and test their performance. Note any under-performing, or broken, parts for replacement. Check to make sure that routine vehicle maintenance, such as oil change and transmission service intervals, are also up to date.

3

Remove broken, or malfunctioning parts, and take them to a local auto parts store to match for replacement. Use only parts that are application-specific to the 2001 Dodge Ram 2500, or intended for universal use. Install new parts according to the manufacturers specifications and perform any neglected routine maintenance.

4

Test drive the vehicle under variable driving conditions and evaluate whether or not the issue has been solved by the replaced or repaired parts. If not, refer back to the manufacturers auto repair guide and re-evaluate the source of the Ram 2500s problem.

The New Beetle comes equipped with a variety of engines, including a 1.8-liter engine with a turbocharger. The cylinder head in a New Beetle is a platform that sits on top of the engine block and forms part of the combustion chamber. A gasket between the cylinder head and engine block ensures a tight seal between the two components. The procedure for removing the cylinder head gasket in a New Beetle requires you to put the lock carrier in the service position. The lock carrier is the front assembly that includes the front bumper, headlights and radiator support.

Instructions

1

Disconnect the front bumper from the lock carrier with a socket wrench. Remove any electrical wiring needed to move the lock carrier into the service position. Disconnect the quick-release screws from the front insulation panel. Then, remove the air guide between the air filter and lock carrier. Release the retaining clamps that attach the wiring harness to the left radiator frame.

2

Remove the No. 2 mounting bolts from the lock carrier with a socket wrench and support it with Support 3369. Remove the remaining mounting bolts from the lock carrier and pull the lock carrier out as far as it will go. Fasten 6 mm bolts to the lock carrier and fender to secure the lock carrier in place.

3

Disconnect the cable from the negative battery terminal to ensure the engine doesnt start while you are removing the cylinder head gasket. Detach the cooling fan drive belt from its pulleys and remove the cooling fan from the engine.

4

Drain the coolant from the radiator into a container and store for later use. Disconnect the intake manifold from the engine with a socket wrench. Detach the accessory drive belts from their pulleys.

5

Remove the regulator valves for the wastegate bypass and the evaporative emissions canister from the engine with a socket wrench. Detach the mass airflow sensor from the engine.

6

Disconnect the housing for the air cleaner with a socket wrench. Detach the wiring harnesses for the engine-coolant temperature sensor and any other electrical components needed to access the cylinder head. Detach the breather line from the crankcase.

7

Remove the fuel lines and oil line from the cylinder head. Disconnect the heat shield and turbocharger from the exhaust manifold with a socket wrench. Detach the coolant hose from the rear of the cylinder head.

8

Detach the upper cover for the timing belt with a socket wrench. Turn the crankshaft clockwise to align the timing mark on the crankshaft with the top dead center mark on the crankcase. Loosen the Torx bolt on the timing belt tensioner with a T45 Torx wrench and push the tensioner down to relieve the tension on the timing belt.

9

Remove the timing belt from the gear of the camshaft, and remove the Torx bolt from the timing belt tensioner with the T45 Torx wrench. Rotate the bracket for the timing belt tensioner forward to access the valve cover and then remove the valve cover with a socket wrench.

10

Disconnect the mounting bolts for the cylinder head with a socket wrench. Lift the cylinder head from the engine block and remove the gasket from the engine block. Clean the remaining traces of gasket material from the cylinder head and engine block with a gasket scraper. Clean the bolt holes on the cylinder head with a shop cloth and blow them dry with compressed air.
