Intake Manifold Repair Procedures

Removal and Installation

1. 1
   Remove the engine cover.
2. 2
   Disconnect the negative battery cable.

   Tightening torque: 3.9 ~ 5.9 N·m

3. 3
   Disconnect the wiring connectors and harness clips, then remove the wiring and protectors from the intake manifold.

   1. OCV (Oil Control Valve) Intake Connector (A)

      

   2. Alternator Connector (A)

      

   3. VIS (Variable Intake System) Connector (A)

      

   4. MAPS (Manifold Absolute Pressure Sensor) and IATS (Intake Air Temperature Sensor) Connector (A)

      

   5. ETC (Electronic Throttle Control) Connector (A)

      

4. 4
   Disconnect the PCV (Positive Crankcase Ventilation) hose (A).

   

5. 5

6. 6
   Remove the ETC (Electronic Throttle Control) module bolts (A). (Refer to Engine Control/Fuel System - ETC System)

   Tightening torque: 9.8 ~ 11.8 N·m

   

7. 7
   Remove the intake manifold support (A).

   Tightening Torque: 18.6 ~ 24 N·m

   

8. 8
   Remove the intake manifold (A) and gasket (B).

   Tightening Torque: 18.6 ~ 24 N·m

   

   When installing the intake manifold, tighten the bolts and nuts to the preliminary torque, then tighten the bolts and nuts to the specified torque in the sequence shown.

   

9. 9
   Installation is the reverse of removal.

   When installing, replace the gaskets with new ones.
