Intake Manifold - Lower: Installation
- Clean and inspect sealing surfaces of cylinder head and manifold. Gaskets can be reused provided they are free of cuts or tears.
- 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.
- Install fuel rail with injectors.
- Install manifold attaching bolts and tighten in sequence shown in (Fig 1) to 12 N.m (105 in. lbs.). Remove bolt used for aligning manifold.
- Connect the fuel injector electrical connectors.NOTE: Make sure fuel injectors are located in the correct location and position, as upper intake manifold interference could occur.
- Install screw attaching fuel rail support bracket to the throttle body support bracket.
- Connect fuel supply hose to fuel rail. (Refer to FUEL LINE DISCONNECT FITTINGS )
- Install upper intake manifold. (Refer to INSTALLATION - UPPER )
