  Q: How to install the intake manifold and its associated components on Ford Excursion?

  A:

  The process begins by placing the thermostat housing before installing the upper intake manifold with its upper intake manifold gasket and inserting bolts while maintaining a loose torque. You should secure the seven bolts on the fuel injector supply manifold only when needed. The bolts must first receive a tightness of 2 Nm (18 inch lbs.) before getting tightened to 25 Nm (18 ft. lbs.). You should connect the cylinder head temperature sensor and also place the LH radio interference capacitor followed by moving fuel lines along with the vacuum line to the fuel injection supply manifold. Proceed to install the 10 Ignition Coils by adding their bolts to the system and then secure the generator. Connect the electrical connector of the water temperature indicator sending unit along with five connectors of the LH fuel injector and ignition coils. Position the EVR solenoid bracket when it exists before final installation. The throttle body adapter needs installation with a fresh gasket followed by tightening four bolts to 9 Nm (80 inch lbs.) and subsequent additional 85-95 degrees rotation. Next install the EVR solenoid vacuum and electrical connectors while tightening the EGR Valve vacuum line and the EGR valve-to-exhaust manifold tube fittings by hand first and then using torque to 40 - 60 Nm (30 - 44 ft. lbs.). The EGR transducer bracket should be installed with necessary vacuum lines connected together with EGR transducer and Throttle Position Sensor electrical connectors. Clamp the heater hose next to the idle air control motor bypass hose and connector and then secure the five right-hand fuel injector and ignition coil connectors. The vacuum line needs installation before securing the RH radio interference capacitor through its bolt. The vacuum lines should be connected both to the Brake Booster and engine control sensor wiring harness and to the PCV vacuum and coolant hoses. Attach the accelerator bracket using bolts while linking the Accelerator Cable with speed control cables and the return spring. Place the air cleaner outlet tube next to the accelerator cable splash shield before affixing the engine water outlet hose properly. The procedure ends with cooling system filling before connecting the battery ground cable.

  Q: How to remove the intake manifold on Ford Excursion?

  A:

  Begin by disconnecting the battery ground cable along with draining the coolant system for the intake manifold replacement procedure. To begin the task start by taking off the air cleaner outlet tube followed by compressing and sliding the hose clamp for water outlet hose and finally the removal of Accelerator Cable splash shield. Before proceeding you need to relieve the fuel system pressure followed by accelerator cable speed control cable disconnection while taking out the return spring to place the accelerator cable bracket to the side. The first step includes cutting connections of the PCV vacuum hose together with coolant lines in addition to braking vacuum systems and engine monitor cables. Use a wrench to remove the right-hand bolt of the radio interference cap then place the cap aside before cutting the vacuum supply line. Continue by disconnecting first the five right-hand fuel injector electrical connectors followed by the five Ignition Coil electrical connectors then the idle air control motor electrical connector and bypass hose and the heater hose. The technician should disconnect EGR transducer and throttle position sensor connectors before positioning the EGR Valve to exhaust manifold tube while detaching upper fittings and loosening lower fittings. Remove the EGR valve vacuum line together with the EVR solenoid electrical and vacuum harness if these components exist. The throttle body adapter needs removal by uninstalling its four bolts along with the gasket. You must detach the EVR bracket when present by removing the bolts. First disconnect the five left-hand fuel injector electrical connectors and then the ignition coil connectors and finally remove the water temperature indicator sender unit electrical connectors. The generator and ignition coils must be removed by dissolving their ten bolts before disconnecting the fuel injection supply manifold by removing its fuel lines and vacuum connector from the Fuel Pressure Regulator. The bolt needs removal before setting the capacitor aside and then disconnecting the cylinder head temperature sensor. First remove the water Thermostat together with the housing unit and then proceed with removing the bolts before extracting the upper intake manifold and intake manifold gaskets that needs disposal. You should detach the fuel injection supply manifold by unbolting its four support points before disassembling the upper from the lower intake manifolds by removing all ten bolts. Regular cleaning of mating surfaces requires caution as metal scrapers and wire brushes together with abrasive tools should be avoided to stay safe from leak paths.
