2001 Lincoln Continental Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the intake manifold on 2001 Lincoln Continental?

  A: All repair and servicing of an intake manifold begins after disconnecting the battery ground cable and emptying the engine cooling system. First step requires disconnecting the fuel line before removing the air cleaner outlet tube. The service starts with nut removal from the engine sensor control wiring at the valve covers and follows with removing the nut and bolt to relocate the generator battery lead before disconnecting both the generator electrical connector and generator mounting bracket bolts and nuts. The bypass tube must be detached from its coolant hoses and Engine Coolant Temperature (ECT) sensorconnector before stud removal along with bypass tube disposal of O-rings. To access the throttle body the technician must disconnect the mass air flow sensor connector then separate it from the accelerator snow shield. After taking out the bolt and pushpin they can remove the shield. The technician should disconnect the accelerator cable and speed control actuator cable from the throttle body. Remove first the bolts and accelerator cable bracket and then disconnect the chassis vacuum supply tube and positive crankcase ventilation tube and engine vacuum supply line. The technician disconnects the fuel pressure sensor vacuum line and its electrical connector alongside the evaporative emissions return line and heater water hose and the vacuum lines which service both the EGR valve and EGR vacuum regulator solenoid. Detach all electrical connectors of the eight fuel injectors and three engine control sensors from their positions on the Idle Air Control (IAC) valve, Throttle Position (TP) sensor and Mass Airflow (MAF) sensor. The procedure requires starter electrical connector separation followed by EGR tube and ignition coil detachment at the EGR valve before moving on to detach the engine wiring harness holders from intake manifold studs. Position all wiring harnesses to the side after these steps. The sequence-ordered removal of intake studs and bolts will allow you to uninstall the intake manifold assembly together with its intake gaskets for disposal. Start by removing the EGR valve and idle air control valve after which you should progress to remove the throttle body component and put in new gaskets if required. Remove the unit consisting of the fuel manifold with injectors by taking out the four bolts to clean all sealing surfaces. Start by putting new intake manifold gaskets in place first before installing fuel injectors in the correct order then unite them with fuel manifold while tightening their four bolts. Place the throttle body along with a new gasket on its surface then install all bolts before applying 9 Nm torque force together with an additional 90-degree rotation. Installation of new idle air control gasket requires a new idle air control valve which needs to be tightened to 9 Nm (80 inch lbs.) and then receive an additional 90 degree rotation. You should install the EGR valve together with its gasket while executing two stages of tightening. Begin by fastening the bolt to 20 Nm (15 ft-lbs.) torque before adding another 90-degree rotation. After placing the intake manifold in position, install its bolts and studs without full torque then torque them to the specified sequence. Reposition all engine wiring harness holders onto their respective intake manifold studs after which connect the vacuum line with EGR tube to the EGR valve while reattaching engine control sensor wiring to both IAC valve and TP sensor and MAF sensor as well as all eight fuel injectors. Install engine wiring harness covers before connecting electrical connectors with vacuum lines to an EGR vacuum regulator solenoid, heater water hose, main evaporative emissions return line along with the vacuum line and electrical connector to the fuel injection pressure sensor. After reattaching the chassis vacuum supply tube and positive crankcase ventilation tube the technician should install the engine vacuum supply line followed by the accelerator cable bracket and speed control actuator cable. Install the snow shield then add the bolt with pushpin and connect the mass air flow sensor wires after placing new O-ring seals onto the water bypass tube. Enhance safety by keeping the O-ring seal intact throughout the installation procedure. The cylinder-head O-ring should undergo cleaning before applying Premium Engine Coolant E2FZ-19549-AA (green) or recycled coolant which meets Ford specification ESE-M97B44-A and water to the water bypass tube O-ring. Position the water bypass tube support braces onto the intake manifold inner studs before installing the bypass tube while attaching two studs. Attaching the generator mounting bracket in place while you join the generator electrical connector and position the generator battery lead followed by fastening the nut and bolt. The engine control sensor wiring electrical connector should be installed onto the engine coolant temperature sensor and bypass tube hoses must be reinstalled followed by securing the two nuts to retain engine control sensor wiring on the valve cover. The procedure ends by reattaching the fuel line followed by installing the air cleaner outlet tube and reconnecting the battery ground cable and starter and ignition coils and performing cooling system filling and bleeding.
