2004 Ford Focus Intake Manifold Parts Q&A

• Q: How to service and repair the intake manifold on 2004 Ford Focus?

  A: Service and repair procedures on the intake manifold start with cooling fan motor removal together with shroud and continued by lower intake manifold bolt removal. The service starts by removing the air cleaner outlet tube while loosening its retaining clamps and the accelerator control snow shield. First disconnect the emissions breather tube from its position before you detach the throttle position (TP) sensor electrical connector to set the wiring harness aside. The next procedure requires you to remove the idle air control (IAC) valve electrical connection and place the wiring harness besides. Begin throttle cable disconnect by unfastening both accelerator cable and speed control cable from the throttle linkage plus the removal of accelerator cable bracket retaining bolts. The next step includes evaporative emissions hose removal followed by disconnection of the temperature manifold absolute pressure (TMAP) sensor electrical connector and all electrical connectors whose wires must be placed aside. Unplug the electrical connector of the outward intake manifold runner control (IMRC) actuator while you undo the vacuum hoses connecting the regulator and power brake tube from its quick release coupling. You must mark the bolt positions first since the indicator tube uses two different bolt sizes before uninstalling both bolts. To remove the intake manifold you need to first take out the seven bolts at the manifold opening after lifting it up to disconnect the knock sensor (KS) wiring harness and the positive crankcase ventilation (PCV) hose. The installation process begins with gasket inspection to decide whether new ones are needed then adds the PCV hose along with connecting the KS wiring harness. You must reinstall the bolts according to markings when you place the intake manifold in position and secure the seven mounting bolts followed by the two oil level indicator tube bolts. After installation of the fuel pressure regulator vacuum hose the IMRC actuator electrical connector needs to be connected followed by the brake booster tube reconnection. You should begin by reconnecting all wiring harnesses and connectors after which you should join the TMAP sensor electrical connector and the evaporative emissions hoses. Next install the accelerator cable bracket before placing in the accelerator cable and speed control cable if the vehicle has this equipment. The repair sequence ends with reattaching the IAC wiring harness and connector as well as the TP sensor electrical wiring harness and connector. Then install the air cleaner outlet tube followed by the accelerator control snow shield and the cooling fan motor and shroud. The conclusion step is installing the lower intake bolt.
