2004 Ford Taurus Intake Manifold Parts Questions & Experts Answers

• Q: How to service the upper intake manifold on 2004 Ford Taurus?

  A: A proper procedure to service the upper intake manifold starts by disconnecting the battery ground cable. Unplug the air cleaner outlet pipe by detaching its tubes followed by releasing both clamps. The service procedure starts by eliminating pin-type retainers and the snow shield before unfastening the accelerator cable and speed control cable and throttle return spring from the throttle body. Disassemble the bolts before setting the accelerator cables along with the bracket to the side. As part of the procedure remove the electrical connectors from the Throttle Position sensor and Intake Air Control (IAC) while you release the harness retainer from the throttle body stud bolt. Begin by disconnecting the vacuum hose combined with the Evaporation Emissions return tube after which remove the upper intake manifold support bracket bolt and nut and position the bracket and harness to the side. To accomplish this step first loosen the nut and then detach the Exhaust Gas Recirculation (EGR) tube from the EGR valve before proceeding to disconnect the Positive Crankcase Ventilation (PCV) tube from the upper intake manifold. Separate the fuel supply manifold pressure sensor vacuum tube as well as the PCV tube from the PCV valve before removing both parts. The installer disconnects both the EGR vacuum regulator solenoid and the Intake Manifold Runner Control (IMRC) electrical connectors while detaching the pin-type harness retainer from the upper intake manifold. Before taking out the upper intake manifold bolts, remove its spark plug wire holder section at the valve cover stud and disconnect the radio interference capacitor central wiring connection. Cleaning all sealing areas must be completed before fitting the components while gasket inspection of the upper intake manifold requires replacement if necessary. You should tighten the bolts on the upper intake manifold through two steps starting with hand tight, then proceeding to 10 Nm (89 inch lbs.). You should install the spark plug wire holder onto the valve cover stud before bringing together the radio interference capacitor electrical connector. The EGR vacuum regulator solenoid and IMRC electrical connectors must be connected with a pin-type harness retainer attached to the upper intake manifold. The PCV tube requires reattachment to both the PCV valve and the PCV tube running to the upper intake manifold. Similarly, the fuel supply manifold pressure sensor vacuum tube and PCV tube need reconnection to the upper intake manifold. Tighten the EGR tube's connection to the EGR valve and then mount the upper intake manifold support bracket before fastening both the bolt and the nut. Connect first the vacuum hose with the EVAP return tube before proceeding to connect the TP sensor and IAC electrical connectors and fasten the harness retainer to the throttle body stud bolt. Install the accelerator cable bracket before installing its bolts and attaching the accelerator cable as well as speed control cable and throttle return spring to the throttle body. Position the air cleaner outlet pipe after both pin-type retainers and the snow shield installation along with tube connection using clamps and battery ground cable reconnection.
