Removal Procedure

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  1. Disconnect the negative battery cable.
  2. Relieve the fuel pressure. Refer to Fuel Pressure Relief Procedure in Engine Controls.

  13. Remove the 2 bolts and the coolant line (5) from underside of the intake manifold.
  14. Remove the brake booster hose from the intake manifold.
  15. Remove the PCV hose from the intake manifold.
  16. Remove the breather hose from the intake manifold.
  17. Remove the fuel pressure regulator vacuum hose from the intake manifold.
  18. Remove the bolt that holds the fuel line bracket (9) to the intake manifold.
  19. Disconnect the wiring harness from the retaining clamps.
  20. Remove the banjo fitting and washer from the rear end of the fuel rail.

    21. Object Number: 467905 Size: SH
  21. Remove the 2 bolts that hold the fuel lines to the fuel rail.
  22. Remove the 2 bolts and the intake manifold front support bracket.
  23. Remove the 2 bolts and the intake manifold top support bracket.

    24. Object Number: 468062 Size: SH
  24. Remove the 9 nuts and 4 bolts from the intake manifold.
  25. Remove the intake manifold from the cylinder head.
  26. Remove the intake manifold gasket from the cylinder head.
  27. Inspect the intake manifold for cracks, warpage or other damage.
  28. Clean the gasket sealing surfaces.
  29. Remove the following components from the intake manifold and transfer as necessary:
    30. • The Throttle Body (7)
    • The EGR valve (2)
    • The EGR pipe
    • The MAP sensor (3)

Installation Procedure

    Object Number: 468062 Size: SH
  1. Install the following components to the intake manifold as necessary:
    2. • The Throttle Body (7)
    • The EGR valve (2)
    • The EGR pipe
    • The MAP sensor (3)
  2. Install the new intake manifold gasket to the cylinder head.

    3. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  3. Install the intake manifold to the cylinder head. Secure the intake manifold with the 9 nuts and the 4 bolts.
