Intake Manifold Installation Upper Intake


    Object Number: 31659  Size: SH
  1. Install a NEW upper intake manifold gasket into the groove of the intake.
  2. Important: Two stud type bolts installed into the lower intake manifold diagonally opposite from each other will aid in positioning upper intake manifold to the lower intake manifold.


    Object Number: 31649  Size: SH
  3. Install the upper intake manifold. Do not pinch the injector wires between the upper and lower intake manifolds.

  4. Object Number: 31828  Size: SH

    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.

  5. Install the upper intake manifold bolts and studs.
  6. Tighten the upper intake manifold bolts and studs:
  7. Tighten

    1. Tighten the upper intake manifold bolts and studs on the first pass to 5 N·m (44 lb in).
    2. Tighten the upper intake manifold bolts and studs on the final pass to 10 N·m (88 lb in).

    Object Number: 31868  Size: SH
  8. Install the vacuum hoses.

  9. Object Number: 31466  Size: SH
  10. Install ignition coil and studs.
  11. Tighten
    Tighten the ignition coil studs to 12 N·m (106 lb in).

Intake Manifold Installation Lower Intake

    Important: Do not reuse intake manifold gaskets. Always install new gaskets.


    Object Number: 38512  Size: SH
  1. Apply sealant to the intake manifold gasket, cylinder head side.
  2. Install the gaskets onto the cylinder head.
  3. Notice: Apply the proper amount of the sealant when assembling this component. Excessive use of the sealant can prohibit the component from sealing properly. A component that is not sealed properly can leak leading to extensive engine damage.


    Object Number: 26744  Size: SH
  4. Apply a 5 mm (0.197 in) bead of approved sealant to the front and rear engine block sealant areas. Extend the sealant bead 13 mm (0.499 in) up the cylinder head in order to seal and retain the gaskets.

  5. Object Number: 26743  Size: SH
  6. Apply a 5 mm (0.197 in) bead of approved sealant to the back of the engine block sealant areas. Extend the sealant bead 13 mm (0.499 in) up the cylinder head in order to seal and retain the gaskets.

  7. Object Number: 31510  Size: SH
  8. Install the lower intake manifold to the engine. Apply an approved sealant to the lower intake manifold bolts.
  9. Install the lower intake manifold bolts.

  10. Object Number: 31698  Size: SH
  11. Use the tightening sequence shown in order to tighten the bolts in three steps.
  12. Tighten

    1. Tighten the bolts in the first pass to 3 N·m (27 lb in).
    2. Tighten the bolts in the second pass to 12 N·m (106 lb in).
    3. Tighten the bolts in the final pass to 15 N·m (11 lb ft).

    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.

  13. Install oxygen sensor wire support bracket and nut.
  14. Tighten
    Tighten nut to 11 N·m (97 lb in).

  15. Install EGR inlet tube, clamp, and bolt.
  16. Tighten
    Tighten bolt to 25 N·m (18 lb ft).

  17. Install canister purge system tubing.
  18. Install PCV valve and hose.
