Intake Manifold Lower
INTAKE MANIFOLD LOWERREMOVAL
1. Release fuel system pressure.
2. Disconnect negative battery (1)cable located in trunk.
3. Remove upper intake manifold.
4. Disconnect injector electrical connectors (2).
5. Disconnect fuel supply hose (1) from fuel rail.
6. Remove bolts attaching fuel rail (1 - 4).
7. Remove fuel rail and injectors as an assembly
8. Remove manifold attaching bolts.
9. Remove lower manifold.
10. Inspect manifold.
INSPECTION
Check manifold for: Damage and cracks Gasket surface damage or warpage Damaged fuel injector ports If the manifold exhibits any of these conditions, replace the manifold.
INSTALLATION
1. Clean and inspect sealing surfaces of cylinder head and manifold. Gaskets can be reused provided they are free of cuts or tears.
2. Install lower manifold gasket.
3. Position manifold on cylinder head surfaces.
NOTE: For ease of installing upper intake manifold, install a bolt 2 - 3 turns to the rearmost attaching hole of intake. This will properly position lower manifold.
4. Install fuel rail with injectors and start bolts (1 - 4).
5. Install manifold attaching bolts and tighten in sequence shown in to 12 Nm (105 inch lbs.). Remove bolt used for aligning manifold.
6. Connect the fuel injector electrical connectors (2).
NOTE: Make sure fuel injectors are located in the correct location and position, as upper intake manifold interference could occur.
7. Connect fuel supply hose (1) to fuel rail.
8. Install upper intake manifold.
