2001 Ford Excursion Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the intake manifold on 2001 Ford Excursion?

  A: Keep all smoke and open fire away from fuel components because flammable mixtures exist when servicing or repairing the intake manifold. Start by disconnecting the ground cable of the battery and draining all the coolant from the system. Begin by removing the air cleaner outlet tube followed by compressing and sliding off its hose clamp to disconnect the water outlet hose and extracting the accelerator cable splash shield. Remove pressure from the fuel system before disconnecting both accelerator and speed controls together with their return spring. The compuvalve and vaporizer should be removed first before positioning the accelerator cable bracket to the side on bi-fuel vehicles. Detach the PCV vacuum hose together with the coolant lines and vacuum elements on the brake booster and engine sensor control portion of the harness. Move the removal of the right-hand bolt because you need to move the radio interference capacitor to the side. Disconnect both vacuum lines along with all five right-hand fuel injector and five ignition coil electrical connectors. The technician disconnects the idle air control motor electrical connector and bypass hose together with the heater hose. The service requires detachment of all EGR transducer connectors and throttle position sensor links as well as EGR transducer vacuum tubing and supporting bracket. The EGR valve requires repositioning toward the exhaust manifold tube but the technician must detach the upper fitting while loosening the lower fitting and unplug the EGR valve vacuum line. Start by removing the four bolts on the throttle body adapter along with the gasket before removing any EGR bracket by removing all its bolts. First disconnect the five left-hand fuel injector electrical connectors with ignition coil connectors and next disconnect the water temperature indicator sender unit electrical connectors. The generator along with ignition coils need ten bolts removed followed by detaching the fuel injection supply manifold through removal of fuel lines and vacuum connector at the fuel pressure regulator. First remove the bolt then place the capacitor to the side where you can disconnect the cylinder head temperature sensor and take out the water thermostat with its housing. Follow the removal sequence for bolts and upper intake manifold as well as intake manifold gaskets before discarding these gaskets. Remove the four bolts securing the fuel injection supply manifold before separating the upper and lower intake manifolds by taking off their ten bolts while avoiding the use of metal scrapers or abrasive tools on aluminum retainer plate surfaces when cleaning all mating points. Place the lower intake manifold onto the upper intake manifold and install its ten bolts loosely before tightening them twice first to 2 Nm (18 inch lbs.) then to 10 Nm (89 inch lbs.). Along with positioning the fuel injector supply manifold you should install its seven bolts. Place the water thermostat and housing in position before installing the upper intake manifold with gaskets and loosely install its bolts for two tightening stages: first 2 Nm and then 25 Nm. Follow up by connecting the cylinder head temperature sensor and left-hand radio interference capacitor along with fuel line and vacuum line installation on the fuel injection supply manifold. Position each of ten ignition coils before bolting them down then install the generator. Follow the procedure to connect the electrical connector for the water temperature indicator sending unit and attach fuel injector electrical connectors and ignition coil connectors from the left-hand side position to their matching units. Install the EGR solenoid bracket under proper placement and bolt it into position. Use a new gasket to install the throttle body adapter by securing four bolts with two-step tightening procedure starting at 9 Nm (80 inch lbs.) and continuing to 85 - 95 degrees. The installation process includes hand-tigthening the EGR valve fittings before torquing them to 40 - 60 Nm (30 - 44 ft. lbs.). Additionally, connect EGR solenoid vacuum and electrical connectors and EGR valve-to-exhaust manifold tube and install the EGR valve vacuum line. The installation requires connecting EGR transducer bracket and vacuum lines and EGR transducer and throttle position sensor electrical connectors. The next sequence is to connect the heater hose alongside the idle air control motor bypass hose and connector as well as the five right-hand fuel injector electrical connectors and five right-hand ignition coil connectors and then the vacuum line. Position the right-hand radio interference capacitor then install vacuum lines to connect the brake booster with the engine control sensor wiring harness before connecting PCV vacuum and coolant hoses. The installation of compuvalve and vaporizer units must be followed by accelerator bracket assembly and acceleration cable and speed control cable attachment with return spring insertion. The last procedure includes adding the accelerator cable splash shield while connecting the engine water outlet hose and positioning the hose clamp before filling the cooling system and reconnecting the battery ground cable.
