Intake Manifold (Lower)

INTAKE MANIFOLD (LOWER)

Fig. 4 Lower Intake Manifold Assembly:

REMOVE OR DISCONNECT
1. Fuel rail.
2. Radiator hose from thermostat housing.
3. Electrical connection at temperature sensor.
4. Heater pipe nut at throttle body.
5. Mounting bolts.
6. Lower intake manifold.
7. Gaskets.

CLEAN
^ Gasket material from mating surfaces.

INSTALL OR CONNECT
1. Gaskets.
2. Lower intake manifold.
^ Installing the bolts in the vertical holes of the manifold will align the intake bolt grommet bores with the threaded holes in the cylinder heads. This will minimize the possibility of cross-threading and/or damage to the grommets which could result in leaking intake manifold gaskets.
3. Lower intake manifold mounting bolts. Insert rubber isolators fully into manifold flange before tightening any fasteners.

TIGHTEN
^ Draw lower manifold in place by tightening bolts gradually, starting with the middle bolts and working in a circular pattern. DO NOT tighten one side or one end fully.
^ Bolts to 25 Nm (18 lb. ft.).
^ Remove the two bolts in the vertical holes of the intake manifold.

4. Heater hose pipe nut at throttle body.
5. Electrical connection at temperature sensor.
6. Radiator hose to thermostat housing.
7. Fuel rail.
