Lower Intake Manifold
Lower Intake ManifoldMaterial:
Removal
CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
1. Disconnect the fuel tube spring lock coupling. For additional information, refer to Fuel Delivery and Air Induction.
2. Drain the engine cooling system. For additional information, refer to Cooling System.
3. Remove the push rods.
4. Disconnect the fuel rail pressure (FRP) sensor electrical connector.
5. Disconnect the 6 fuel injector electrical connectors.
6. Disconnect the upper radiator, degas bottle and heater hoses.
7. Disconnect the engine coolant temperature (ECT) sensor electrical connector.
8. Disconnect the camshaft position (CMP) sensor electrical connector.
9. Remove the 8 bolts and the lower intake manifold.
10. Remove the intake manifold gaskets and the end seals.
Installation
1. Using metal surface cleaner, clean all the sealing surfaces.
2. NOTE: If the lower intake manifold is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
Apply silicone gasket and sealant at the 4 cylinder block-to-cylinder head seams.
3. Install the lower intake manifold gaskets and end seals.
^ Position the intake manifold gaskets.
^ Position the intake manifold end seals.
4. Install the intake manifold. Tighten the 8 bolts in 2 stages in the sequence shown.
^ Stage 1: Tighten to 15 Nm (11 ft. lbs).
^ Stage 2: Tighten to 32 Nm (24 ft. lbs).
5. Connect the CMP sensor electrical connector.
6. Connect the engine ECT sensor electrical connector.
7. Connect the upper radiator, degas bottle and heater hoses.
8. Connect the 6 fuel injector electrical connectors.
9. Connect the FRP sensor electrical connector.
10. Install the push rods.
11. Connect the fuel tube spring lock coupling.
12. Fill and bleed the engine cooling system.
