    NOTICE

    Keep all parts clean from contaminants.

    Contaminants may cause rapid wear and shortened component life.


  1. Evacuate as much fuel and oil as possible from the cylinder head before installing the injector. Several evacuations may be necessary. Use Tooling (E) to remove the fuel and oil from the cylinder head.

  1. Use Tooling (B) to clean injector seating (5) .

  1. Use Tooling (C) to clean tip bore (6) .

    Note: Do not reuse seals. Use new seals for installation.

  1. Lubricate the bore lightly with a 50/50 mix of clean engine oil and Tooling (D) .

  1. When you install a new injector the E-Trim value must be programmed into the engine control module. The injector confirmation code may need to be programmed into the engine control module. E-Trim Value (X) is a twelve digit alphanumeric code that is supplied with the data sheet that comes with the new injectors. Injector Confirmation Code (Y) is a four digit numeric code. Both of the codes are located on the top of electronic unit injector (2) . Use the following menu to program the E-Trim value.

    • ECM Summary Screen

    • Service Menu

    • Calibration

    • Injector Code Calibration


    NOTICE

    When an electronic unit injector is replaced, the new electronic injector code must be programmed into the engine's personality module software by using the calibration menu on the Electronic Service Tool. If the new electronic injector code is not entered, the characteristics of the previous electronic unit injector is assumed.

    If it is not possible to immediately reprogram the electronic injector code into the personality module software, the engine will not be severely harmed. The new electronic injector code should be reprogrammed as quickly as possible in order to optimize engine performance.


  1. Install electronic unit injector (2) and unit injector clamp (4) .

    Note: Use new bolt (3) .

  1. Install bolt (3) .

  1. Connect harness assembly (1) to electronic unit injector (2) . Tighten harness assembly (1) to a torque of 2.50 ± 0.25 N·m (22 ± 2 lb in).

End By: Install the rocker shafts. Refer to Disassembly and Assembly, "Rocker Shaft and Pushrod - Install".
