2002 Lincoln LS Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the upper intake manifold on 2002 Lincoln LS?

  A: Begin repairs of the upper intake manifold by first disconnecting the battery ground cable along with draining the engine cooling system. Begin servicing of the upper intake manifold by first removing both the engine appearance cover and air cleaner outlet tube. Remove the wire retainer from the stud before disconnecting the Throttle Position (TP) sensor and Idle Air Control (IAC) solenoid electrical connectors. The mechanism starts with accelerator and speed control cable removal followed by unbolting the cable bracket and its retaining hardware. The technician must disconnect the throttle body hoses that encompass both coolant lines together with Positive Crankcase Ventilation PVC hose and vapor purge hose and also remove the vacuum hose. First remove the exhaust manifold-to-Exhaust Gas Recirculation valve tube nut plus cowl vent screen as well as mounting bracket vacuum hoses. Afterwards remove the mounting bracket brace and Exhaust Gas Recirculation valve tube nut. The differential pressure feedback EGR electrical connector must be disconnected followed by removing stud and nut to set the differential pressure feedback EGR transducer aside. First disconnect the vacuum hose attached to the rear of the upper intake manifold before removing the fuel pressure sensor shield using its nut and bolts. The Intake Manifold Tuning (IMT) valve electrical connector requires both vacuum line and electrical connector disconnections in order to carry out the procedure. Disassemble the upper intake support bolt together with the front intake manifold support bolt before removing the upper intake manifold and checking its gaskets for replacement if needed. When installing the upper intake manifold secure the bolts by hand and afterward fit the fuel pressure sensor shield and fasten it with the provided nut. Follow the specified sequence to tighten all upper intake manifold bolts before you install the differential pressure feedback EGR along with its nut and stud. The installation requires fitting the upper intake manifold support bolt and upper intake support bolt so you can proceed to attach the EGR vacuum regulator solenoid as well as the IMT valve electrical connector and vacuum hose to the upper intake manifold's rear surface. The differential pressure feedback EGR electrical connector needs to be reconnected after installing the bracket by clipping vacuum hoses into their corresponding places on the mounting bracket. You should first install the brace and cowl vent screen before you can attach both the exhaust manifold-to-EGR tube nut and the vacuum hose. The installation process involves connecting all throttle body hoses including coolant hoses with PVC hose and vapor hose before proceeding to set up the cable bracket and attach accelerator and speed control cables. Last steps involve connecting TP sensor and IAC solenoid electrical connections, installing the air cleaner outlet tube, the engine appearance cover while filling the engine cooling system and reattaching the battery ground cable.
