2003 Ford Escape Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the upper intake manifold on 2003 Ford Escape?

  A: Service and repair of the upper intake manifold requires beginning with air cleaner outlet tube and cranks case ventilation tube removal before clamping them loose and finally removing the air cleaner outlet tube again. Begin the procedure by uninstalling the three nuts which secure the engine appearance cover then disconnect the throttle cable and speed control cable (if equipped) followed by its bracket bolts. After disconnecting the throttle position (TP) sensor electrical connector the technician should disconnect idle air control (IAC) electrical connector then move on to disconnect the exhaust gas recirculation (EGR) valve vacuum hose and EGR tube nut. Unplug both the vacuum regulator solenoid of the EGR from its electrical connector while you remove its vacuum hose and disconnect the three vacuum hoses behind the intake manifold starting with the chassis vacuum hose and moving to both engine vacuum hose and positive crankcase ventilation (PCV) hose. The service procedure also involves disconnecting the vapor management valve (VMV) vacuum hose along with the two electrical connectors on the left side of the upper intake manifold and the power steering pressure (PSP) sensor electrical connector. First disconnect the bolt that supports the transmission vent hose and bracket before taking out the wire harness nut and eight bolts from the upper intake manifold while discarding the gaskets to thoroughly clean all sealing surfaces. To install the upper intake manifold position it and tighten bolts following a specified sequence while placing new gaskets during that process. Connect the PSP electrical connector while you install the transmission vent tube alongside its bracket with a bolt. Reconnect the wire harness using the nut while installing both electrical connectors at the left intake manifold side and joining the VMV vacuum hose. Secure the upper intake manifold vacuum hoses by reconnecting the chassis vacuum hose, engine vacuum hose and PCV hose at its back end. Complete the electrical vacuum connection of the EGR vacuum regulator solenoid followed by securing the EGR valve vacuum hose through its tube nut. Start with connecting the TP sensor and IAC electrical connectors. Then install the throttle cable bracket bolts and connect both throttle cables and the speed control cable when present. To complete installation place the air cleaner outlet tube properly then add the hoses and clamp them before you add the engine appearance cover.
