  Q: How to install the intake manifold and its components on Ford E-150?

  A:

  First step to install the intake manifold involves placing intake manifold gaskets with the intake manifold before conducting bolt installation in a loose manner. Before proceeding with installation apply the Thermostat housing to the engine block before placing the thermostat and a new O-ring seal. The therapist housing bolts need sequence tightening with intake manifold bolts because you must first loosely install the bolts on the thermostat housing and then perform two stages of tightening: 2 Nm (18 inch lbs.) followed by 25 Nm (18 ft. lbs.). Starting from the intake manifold bracket attach the pushpin retainer while adding the screws and 10 coils afterward move the LH fuel charge wiring harness into place before securing it with bolts. Fitting the RH fuel charging wiring harness requires stud bolts followed by adjustment of the transmission fluid level indicator tube and fitting the retaining nut. Fit together the 10 ignition coil electrical connectors, 10 fuel injector electrical connectors, FRP sensor electrical connector and vacuum connector with the coolant hose. Professional technicians should apply the Throttle Body adapter gasket first to the assembly before tightening the bolts in two sequence: starting at 9 Nm (80 inch lbs.) then adding an additional 90-degree (1/4 turn). Ensure a secure connection of the Brake Booster with evaporative emission hose and Positive Crankcase Ventilation (PCV) coolant hose together with heated PCV tube and engine vacuum harness and Throttle Position (TP) sensor electrical connector with its red clip pushed in place. After connecting the electronic Throttle Body (TB) electrical connector with its red clip and installing an upper radiator hose you should connect the fuel hose spring lock couplings. The generator installation requires ground Battery Cable connection after which the engine cover goes on and the assembly of air cleaner components follows before cooling system filling.

  Q: How to remove the intake manifold on a 4.6L engine on Ford E-150?

  A:

  Initiating 4.6L intake manifold removal requires safety precautions like eliminating fuel component exposure to tobacco smoke or flames together with fuel system pressure relief to avoid unintended spraying. Start the procedure by removing the engine cover along with the disconnecting of the fuel supply tube spring lock coupling. You must disconnect the Battery Cable ground then empty the cooling fluid from the system. You should first disconnect all quick connect couplings before removing the PCV tube and then the Throttle Body. Unplug eight Ignition Coils while separating the upper radiator hose and heater coolant hose. The generator pulley requires generator wiring harness retainer disconnection followed by clockwise tensioner rotation to remove the accessory Drive Belt while generator support bracket bolts must also be removed. First remove the transmission fluid level indicator and tube bolt before putting indicator and tube in a suitable position. The technician disconnects the vacuum harness connector alongside the crankcase vent tube quick connect coupling from the LH valve cover as well as the EGR system module electrical connector and the vacuum hose connector. Seperate the exhaust manifold-to-EGR system module tube and secure the removal of two bolts from the EGR system module by discarding its gasket. The technician needs to remove the fuel pressure and temperature sensor electrical connector followed by the EVAP system vapor tube quick connect coupling from the intake manifold and disconnect the PCV coolant hose from the throttle body adapter. Disconnect the vacuum harness connector from the intake manifold and every one of the eight fuel injector electrical connectors. Remove the heater outlet tube from the rear of the RH cylinder head by disconnecting its wiring harness retainer then its coolant hose connection before removing the stud bolt. Position the heater outlet tube to the side for work. Detach the two electrical connector position retainers from the support bracket followed by placing the wiring harness onto the transmission. To remove the Thermostat system begin by discarding the O-ring seal while doing away with the two bolts, thermostat housing and thermostat. Use a discard bin to remove the intake manifold gaskets before inspecting the manifold for any damage when taking out the nine bolts and manifold. Clean the sealing surfaces with a plastic scraping tool before using silicone gasket remover. Place the new intake manifold gaskets next to the intake manifold before installing it loosely with the nine bolts. Install a new thermostat O-ring seal before putting on the thermostat housing and installing the two bolts in a loose manner. The installation requires stages to tighten the eleven bolts with a torque wrench. Begin by using 2 Nm (18 lb-in) and then proceed to 25 Nm (18 lb-ft). First secure the two electrical connector position retainers on the support bracket and place the heater outlet tube in position while installing and fastening the stud bolt to 25 Nm (18 lb-ft). Connect the tubing to the heater outlet tube while you also attach the wiring harness retainer at the rear of the RH cylinder head and fit the eight fuel injector electrical connections. The PCV coolant hose must be attached to the throttle body adapter followed by vacuum harness connector installation to the intake manifold and an EVAP system vapor tube quick connect coupling to the intake manifold position. Connect the fuel pressure and temperature sensor electrical connector while positioning the EGR system module along with its new gasket and secure the two bolts with 25 Nm (18 lb-ft) torque. Screw the exhaust manifold-to-EGR system module tube by securing both upper and lower fittings with 42 Nm (31 lb-ft) torque. Close the EGR system module vacuum hose after reconnecting its electrical connector before joining the crankcase vent tube quick connect coupling to the LH valve cover. Also install the transmission fluid level indicator with its tube bolt which requires 28 Nm (21 lb-ft) of torque. Screw the transmission fluid level indicator into its tube before tightening both parts to 10 Nm (89 lb-in) while also connecting the vacuum harness connector. Install the generator support bracket followed by the three bolts while reconnecting the generator wiring harness retainer then use the tensioner to rotate clockwise for generator pulley accessory drive belt assembly. You need to join the heater coolant hose with the upper radiator hose and the fuel supply tube spring lock coupling. First install the eight ignition coils while positioning the PCV tube and then connect the quick connect couplings. Complete the installation by attaching the throttle body along with the engine cover and battery ground cable. Then perform a cool system fill-up and bleeding procedure.
