2003 Lincoln Town Car Intake Manifold Parts Q&A

• Q: How to service the intake manifold on 2003 Lincoln Town Car?

  A: Service of the intake manifold should start with disconnecting the ground cable from the battery as well as draining the engine cooling system. Start the procedure by disconnecting both the air cleaner and outlet pipe followed by separating the fuel spring lock coupling. The first step of the service requires removing the wiper mounting arm together with the pivot shaft and accessory drive belt. A hoist must raise the car and technicians must disconnect both the Crankshaft Position (CKP) sensor electrical connector and the pin-type retainers from A/C compressor studs. The technicians must detach the Power Steering Pressure (PSP) switch and A/C compressor clutch as well as the oil pressure sensor and power steering electrical connectors. The technician should lower the vehicle while disconnecting fuel charging wiring electrical connectors attached to all eight ignition coils and fuel injectors. You must disconnect the accelerator cable as well as the speed control actuator cable, throttle return spring and cable retaining bolts before taking them out of the Exhaust Gas Recirculation (EGR) system module tube heat shield. First disconnect the EGR system module tube heat shield bolts and then proceed to remove the electrical connector and vacuum hose together with the EVAP canister purge valve vacuum hose. The generator cable receives disconnection alongside the electrical connector and harness location retainer until the bolts can be removed with the generator mounting bracket. Disconnect the upper radiator hose and check the Idle Air Control (IAC) valve and Throttle Position (TP) sensor electrical connectors as well as disconnecting the heater water hose. The technician removes the EGR system module tube nut that connects to the EGR system module while separate the fuel charging wiring pin-type retainer from the crash bracket and takes out the cables from the same bracket. The crash bracket bolt requires removal after you secure it to a rubber band or tie strap to prevent contact with the cylinder head and detach the stud. The vacuum system starts by disconnecting hoses followed by vacuum harness removal. After that both the generator harness position retainer from LH front stud and the fuel charging wiring pin-type retainer from the manifold's rear need removal. The ground wire connector must be detached from its location on the RH rear stud while also disconnecting the coolant temperature sensor electrical connector. The first step involves removing the bolts and eight ignition coils before proceeding to detach the bolts and water outlet adapter. Remove the water thermostat while discarding its O-ring and detach all bolts which secure the intake manifold after you discard the existing gaskets and prepare both sealing surfaces for cleaning. Begin installation by placing the gasket locator tabs into the slots found in the cylinder head while installing new intake manifold gaskets. First install the intake manifold with a gentle bolt tightening before you install ignition coils and complete their bolt tightening process. First install the crash bracket then loosely place the bolt and stud and finally install a new O-ring and the water thermostat. The water outlet adapter bolts must be installed loosely first before tightening them according to their specified order and ultimately tightening the stud and bolts. Install the EGR system module tube to its module before installing the EGR tube heat shield and securing all bolts. Worm-style clamps of proper size should be used to link the heater water hose before positioning the clamp. The IAC control valve and TP sensor electrical connectors need connection while their cables must be mounted to the crash bracket before applying new clamps to the upper radiator hose. Fasten the generator mounting bracket into position followed by bolt installation. Proceed to link the electrical connector at the generator and then connect the generator cable along with the harness location retainer. The system requires positioning of the vacuum harness to connect a vacuum hose to the EVAP canister purge valve before installing all vacuum hoses and electrical connector. Install all cables on the EGR system module tube heat shield before connecting the accelerator cable with its speed control actuator cable and throttle return spring followed by attaching cable retaining bolts. Secure the wiring electrical connectors of the fuel charging system to both the eight fuel injectors and their associated ignition coils followed by the coolant temperature sensor wire. After raising the vehicle you must connect the power steering, oil pressure sensor and PSP electrical connectors and A/C compressor clutch while attaching the pin-type retainers to the A/C compressor bracket. The operation must also include connecting the CKP sensor electrical connector. Procure the fuel spring lock coupling followed by installing all its components including the access drive belt and wiper mounting arm and pivot shaft before mounting the outlet pipe and air cleaner. The battery ground cable needs to be reconnected while inspecting engine oil and performing engine cooling system fill-up and bleeding.
