How to Change the Water Pump on a Cummins 5 9L Turbo Diesel

How to Change the Water Pump on a Cummins 5.9L Turbo Diesel

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.

How do I Repair a 2001 Dodge 2500 RAM Cummins Turbo Diesel

How do I Repair a 2001 Dodge 2500 RAM Cummins Turbo Diesel?

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.

How to Remove a 12 Valve Cummins Injection Pump

How to Remove a 12-Valve Cummins Injection Pump

The Cummins B series of diesel engines are best-suited for light and medium trucks. The 6BT is a six-cylinder engine with two valves per cylinder, for a total of 12 valves. The Cummins 6BT is typically turbocharged and appears in Dodge trucks from 1994 to 1998, such as the Dodge Ram 2500. This engine uses an injection pump to keep the fuel at high pressure. The removal of the injection pump from a 12-valve Cummins engine requires the No. 1 cylinder to be in the top dead center position.

Instructions

    1

    Remove the cable from the negative battery terminal with a socket wrench. Disconnect the throttle linkage from the engine and remove the fuel drain manifold. Detach the fuel lines and the electrical wiring from the injection pump. Disconnect the fuel air control tube.

    2

    Disconnect the support bracket for the injection pump with a socket wrench. Remove the bracket for the oil filler tube from the front cover of the injection pump. Place a shop rag over the opening in the gear cover to keep debris out of the gear housing.

    3

    Connect a turning tool to the opening in the flywheel housing and attach an extension to the turning tool. Push the top dead center pin on the flywheel housing as you turn the flywheel with the turning tool. Stop turning the flywheel when the pin drops into the gear timing hole. Remove the pin from the hole and detach the turning equipment from the flywheel housing.

    4

    Remove the lock screw and washer from the injection pump with a socket wrench. Tighten the lock screw to 22 foot-pounds with a torque wrench to hold the crankshaft in place. Pull the drive gear for the injection pump from the crankshaft with a gear puller.

    5

    Disconnect the three mounting nuts from the injection pump with a socket wrench and detach the injection pump from the engine. Remove the gasket for the injection pump and clean the mounting surface for the gasket with a shop rag.
