Intake manifold - removal and refitting

Note: If the intake manifold is to be unboltedonly for removal of the cylinder head, then the intake manifold can simply be unbolted from the cylinder head and pushed toward the bulkhead, without disconnecting any hoses, wires or linkage. The following procedure is for complete removal of the manifold from the vehicle.

1 Remove the throttle body as described in

Section 12.

Fuel and exhaust systems 4A•13

2 Label and detach the PCV and vacuum hoses connected to the intake manifold, including those from the vacuum sensor, vacuum servo unit and the air conditioning idle-up actuator - where fitted (see illustration).

3 The intake manifold can be removed with the injectors and fuel rail in place. If the injectors are to be removed from the intake manifold, refer to Section 12.

4 Disconnect the idle speed control valve electrical connector and the hoses from the air pipe at the rear of the manifold.

13.5 From underneath the vehicle, remove 13.6a Unbolt the wiring harness (right the bolt retaining this brace (arrowed) to arrow), then remove the lower manifold bolts the intake manifold

5 Unbolt the upper end of the intake manifold-to-block brace (accessible from under the vehicle), and the upper manifold brace, where fitted (see illustration).

6 Remove the earth strap and mounting nuts/bolts, then detach the manifold from the engine (see illustrations). Note: From under the vehicle, it will be necessary to unbolt the wiring harness, the lower intake manifold bolts, and the two nuts securing the pair of steel pipes to the underside of the intake manifold.
