2000 Lincoln LS Intake Manifold Parts Q&A

• Q: How to service and repair the upper intake manifold on 2000 Lincoln LS?

  A: The service and repair process for the upper intake manifold begins with disconnecting the ground cable and draining from the engine cooling system. Start by removing the engine appearance cover together with the air cleaner outlet tube. The procedure starts by disconnecting TP sensor connectors and IAC solenoid connectors with electrical connectors while unfastening accelerator cables and speed control cables and removing the cable bracket. Disconnected hoses must include throttle body hoses and their components which are coolant hoses as well as Positive Crankcase Ventilation (PVC) hose alongside vapor purge hose. The service technician should disconnect both the Exhaust Gas Recirculation (EGR) vacuum hose and the EGR to exhaust manifold tube nut. Start by extracting the accelerator and cruise control cables from the bracket after removing cowl vent screen and vacuum hoses attached to it. Unplug the differential pressure feedback EGR electrical connector before removing the stud and nut under which the differential pressure feedback EGR transducer will be placed aside. Begin by removing the fuel pressure sensor shield using its nut and bolts after disconnecting the vacuum hose attached to the upper intake manifold rear. Properly disconnect both the electrical connector of the Intake Manifold Tuning Valve (IMTV) and the Exhaust Vacuum Regulator (EVR) by removing their electrical connector and vacuum line connections. First remove the support bolt from the upper intake and bolt from the front intake manifold followed by upper intake manifold bolts then check the gaskets for replacement needs. The first step for installation includes setting the upper intake manifold with its gaskets in position before installing the fuel pressure sensor shield using the nut for fastening. Screw and tighten the upper intake manifold bolts following their specified installation order. The differential pressure feedback EGR installation requires securing its stud and nut before adding the upper intake manifold support bolt alongside the upper intake support bolt. The EVR installation requires an electrical connection and vacuum line attachment followed by connecting IMTV electrical wires along with the vacuum hose to the upper intake manifold's rear surface. The procedure includes connecting the differential pressure feedback EGR electrical connector followed by installation of the accelerator and cruise control cables into the bracket and the vacuum hoses into their respective mounting bracket. The installation process includes putting back the cowl vent screen after you connect both the EGR to exhaust manifold tube nut and its vacuum hose. The throttle body installation requires reattachment of all hoses together with the coolant hoses and PVC hose and vapor purge hose. The cable bracket needs installation with bolt fasteners followed by accelerator cable connection with speed control and TP sensor and IAC solenoid electrical wiring. The procedure ends by replacing the air cleaner outlet tube together with the engine appearance cover while also filling engine cooling system reservoirs and reconnecting the battery ground cable.
