2005 Lincoln Navigator Intake Manifold Parts Q&A

• Q: How to service and repair the intake manifold on 2005 Lincoln Navigator?

  A: Start the repair process of the intake manifold by first removing its four throttle body bolts before unscrewing the four fuel rail bolts. First detach the locking clip for fuel injectors and fuel rail then remove fuel injectors from the rail and dispose the 2 O-ring seal from each injector. Starting with the vacuum tube assembly removal from the intake manifold proceed to remove the rod locking clips of the charge motion control valve before extracting the stud bolt then the 2 bolts and finally removing the complete CMCV. Two positive crankcase ventilation (PCV) heater element bolts need removal while discarding the O-ring seal. You need to detach the engine noise shield insulator present on the intake manifold. Remarkably begin the process of assembly by attaching the engine noise shield insulator to the intake manifold. Install a new O-ring seal first while lubricating it with engine oil then fit the PCV heater element before tightening the 2 bolts to 6 Nm (53 inch lbs.). Secure the CMCV by adding the stud bolt with two bolts which receive 10 Nm (89 inch lbs.) torque before placing CMCV rod locking clips. Fasten the vacuum tubing onto the intake manifold before adding clean engine oil to new O-ring seals and then inserting them onto each fuel injector. The fuel rail gets its fuel injectors put together through locking clips before install onto the intake manifold with fuel rail bolts secured at 10 Nm (89 inch lbs.). Start by installing the throttle body and finish the bolt installation process by securing them at 9 Nm (80 inch lbs.) followed by rotating them an extra 90 degrees.
