2004 Lincoln Town Car Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the intake manifold on 2004 Lincoln Town Car?

  A: As a starting point begin service and repair on the intake manifold by disconnecting the battery ground cable then draining the engine cooling system. Start by removing the air cleaner outlet pipe-resonator assembly then disconnect the fuel spring lock coupling and uninstall the wiper mounting arm along with its pivot shaft followed by removing the RH cowl extension through pin-type retainers, nuts and bolts. The LH cowl extension requires removal after disconnecting its electrical connector and removing all its bolts. Engine technicians need to remove the electrical connectors providing fuel charging to eight ignition coils and fuel injectors as well as disconnecting the accelerator cable with speed control actuator cable and throttle return spring and its cable retaining bolts. First remove the cables from the EGR system module tube heat shield before you remove its bolts and the shield itself. You must detach the EVAP canister purge valve vacuum hose and the vacuum hoses and electrical connector at the harness location retainer. First disconnect the engine generator bracket by removing the bolts and then proceed to separate the upper radiator hose and break the connection of IAC valve and TP sensor electrical cables. The procedure requires disconnecting the heater hose followed by removing the EGR system module tube nut from the EGR system module and using a wrench to untighten the exhaust manifold nut which allows you to extract the EGR tube. The technician needs to separate the pin-type retainer on the fuel charging wiring that is attached to the crash bracket then remove the cables from the bracket before removing the crash bracket bolt through the use of a rubber band or tie strap to avoid bracket contact with the cylinder head. The next steps are to take out the stud while also disconnecting the vacuum hoses along with the fuel pressure sensor electrical connector. After that, extract the generator harness position retainer from the LH front stud. The fuel charging wiring pin-type retainer at the manifold rear needs removal before you disconnect the ground wire connector from the RH rear stud and the coolant temperature sensor electrical connector. Eliminate the eight ignition coils with their bolts together with the bolts and coolant outlet adapter and thermostat by discarding the O-ring. Complete the process by removing all bolts from the intake manifold then discard intake manifold gaskets before cleaning the sealing surfaces. To install a new gasket first position the tabs from the cylinder head into the slots of the gasket locator. After setting the intake manifold bolts by hand tighten them while installing the ignition coils followed by bolt tightening procedures. Attach the crash bracket components loosely before following the specified sequence for bolt torquing then tightening the stud. Place the EGR system module tube to the EGR system module before you install the EGR tube with its nut at the exhaust manifold along with positioning the EGR tube heat shield and installing its bolts. Connect both IAC control valve and TP sensor electrical connectors then attach cables to the crash bracket while installing the generator mounting bracket and its mounting bolts. Install the vacuum harness before connecting the electrical connector and harness location retainer and route a vacuum hose toward the EVAP canister purge valve. Install the electrical connector and vacuum hoses to the EGR system module tube heat shield then position all attached cables on it. Install first the accelerator cable before adding the speed control actuator cable and throttle return spring and cable retaining bolts. Finally install the eight fuel injector and ignition coil electrical fuel charging wiring connectors. After connecting the coolant temperature sensor electrical connector you should first install the left-hand cowl extension through extending the component and bolting it down before attaching its electrical connectors. For the right-hand cowl extension also start by extending its components and install the pin-type retainers locking onto the extension followed by fastening the extension and its bolts. Before installing the wiper mounting arm and pivot shaft users need to connect the fuel spring lock coupling and install the air cleaner outlet pipe-resonator assembly as well as reattach the battery ground and check engine oil before using worm-style clamps to attach the upper radiator hose while filling and bleeding the cooling system.
