Intake Manifold Upper

Upper Intake Manifold

Removal

1. Disconnect and isolate the negative battery cable.
2. Disconnect the Inlet Air Temperature (IAT) sensor electrical connector.






3. Remove the air inlet hose from the throttle body.






4. Disconnect the Manifold Absolute Pressure (MAP) sensor electrical connector.






5. Disconnect the PCV hose (1), purge hose (2) and power brake booster hose (3) from the upper intake manifold.
6. Disconnect the electrical connector from the electronic throttle control (5).
7. Remove the fasteners from the throttle body and cylinder head and remove the throttle bracket (4).






8. Remove the wiper module, strut tower support and EGR tube (1).






9. Disconnect the electrical connectors from the manifold tuning valve (1) and short runner valve (2).






10. Remove the fasteners (2) from the intake manifold support brackets.
11. Remove the upper intake manifold retaining bolts, insulation foam pad and manifold. Clean all gasket sealing surfaces.

Installation

1. Clean and inspect the gasket sealing surfaces.
2. Position the new gasket.
3. Install the upper intake manifold insulator foam.
4. Install the upper intake manifold. Tighten the bolts to 12 Nm (105 in. lbs.) starting in the center working outward in a cross sequence pattern.






5. Install the intake manifold support brackets. Tighten fasteners (2) to 12 Nm (105 in. lbs.).






6. Connect the electrical connectors to the manifold tuning valve (1) and short runner valve (2).






7. Install the throttle bracket (4). Tighten fasteners to 12 Nm (105 in. lbs.) at the throttle body and 28 Nm (259 in. lbs.) at the cylinder head.
8. Connect the harness connector to the electronic throttle control (5).
9. Connect the PCV hose (1), purge hose (2) and power brake booster vacuum hose (3) to the intake manifold.






10. Install the EGR tube (1), strut tower support, wiper module and cowl panel.






11. Connect the Manifold Absolute Pressure (MAP) sensor harness connector.






12. Install the inlet hose and connect the IAT sensor harness connector.
13. Connect the negative battery cable and tighten nut to 5 Nm (45 in. lbs.).
