FUEL INJECTOR (w/ DPF) REMOVAL

Note


  • When replacing the injectors (including shuffling the injectors between the cylinders), common rail or cylinder head, it is necessary to replace the injection pipes with new ones.

  • When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.

  • After removing the injection pipes, clean them with a brush and compressed air.


  1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM


    1. Start up the engine.

    2. Turn the A/C switch on.

    3. Operate the cooler compressor at an engine rpm of approximately 1,000 for 5 to 6 minutes to circulate the refrigerant and collect compressor oil remaining in each component into the cooler compressor as much as possible.

    4. Stop the engine.

    5. Using SST, let the refrigerant gas out.

      SST

    Tech Tips

    If the injector compensation code is not correctly registered, it may cause malfunctions.


    1. Read the injector compensation code Click here.

    2. Check that the compensation code of the installed injector is the same as the code registered in the ECM. If the code is not as specified, register the injector compensation code of the injector Click here.
