Disassembly

  1. Remove the heater hose.
  1. Remove the Supercharger (SC) bubbler hose.
  1. Remove the upper and lower SC bypass actuator vacuum tubes.
  1. Remove the 2 bolts and the EGR system module.
  1. Disconnect the vacuum tube from the fuel rail and pressure temperature sensor.
  1. Remove the 4 fuel rail bolts.
  1. Remove the 8 fuel injector clips and the 8 fuel injectors from the fuel rail.

  1. NOTICE: Use O-ring seals that are made of special fuel-resistant material. Use of ordinary O-ring seals can cause the fuel system to leak. Do not reuse the O-ring seals.

    Remove and discard the 16 fuel injector O-ring seals.
  1. Remove the 10 bolts and the SC .
  1. Remove the vacuum tube.
  1. Remove the Intake Air Temperature 2 (IAT2) sensor.
  1. Remove the 5 bolts and the Charge Air Cooler (CAC) tube assembly.
  1. Remove the 2 CAC coolant connector tubes.
  1. Remove the 13 bolts and the lower intake manifold cover.
  1. Remove the 10 bolts, the 2 CAC rail supports and the CAC .

Assembly

  1. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

    NOTE: Apply threadlock and sealer to the CAC bolts prior to installation.

    Position the CAC , the 2 CAC rail supports and install the 10 bolts. Tighten in the sequence shown in 2 stages.
  1. Install a new gasket, the lower intake manifold cover and the 13 bolts. Tighten in the sequence shown.

  1. NOTE: Apply clean engine coolant to the new CAC coolant connector tube O-ring seals.

    Install new O-ring seals on the CAC coolant connector tubes.
  1. Install a new gasket, the CAC coolant tube assembly and the 5 bolts.
  1. Install the IAT2 sensor. Tighten in 2 stages.
  1. Install the vacuum tube.
  1. Install a new gasket, the SC and the 10 bolts. Tighten in the sequence shown in 2 stages.

  1. NOTE: Lubricate the new O-ring seal with clean engine oil prior to installation.

    Install new O-ring seals on each of the fuel injectors.
  1. Install the 8 fuel injectors onto the fuel rail and install 8 new fuel injector clips.
  1. Install the fuel rail and fuel injector assembly onto the intake manifold.
  1. Install the 4 fuel rail bolts.
  1. Connect the vacuum tube to the fuel rail and pressure temperature sensor.
  1. Install a new gasket, the EGR system module and the 2 bolts.
  1. Install the upper and lower SC bypass actuator vacuum tubes.
  1. Install the SC bubbler hose.
  1. Install the heater hose.
