• Q: How to Service and Repair an Intake Manifold on 2001 Ford F-150?

  A: The procedure to service and repair the intake manifold starts with disconnecting the ground cable from the battery followed by draining the fuel system pressure. The service starts with draining the engine cooling system followed by separating the engine air cleaner and the air cleaner outlet tube. The accelerator cable snow shield requires bolt removal while the hose clamp needs compressing and sliding for upper radiator hose disconnection. Disconnecting the throttle body cam requires separation of the accelerator cable as well as speed control actuator cable and removal of the accelerator return spring. Detach the accelerator cable bracket bolts before storing the bracket together with cables. The technician disconnects the main vacuum harness and throttle position sensor then removes the engine vacuum regulator connectors followed by fuel pressure regulator vacuum line and vapor management valve vacuum line together with differential pressure feedback EGR sensor electrical connector. Begin by untightening the nut which disconnects the brake booster vacuum line and bracket and then disconnect the fuel lines and the idle air control motor electrical connector. Begin by setting the EGR valve aside from its exhaust manifold tube position and disconnect the upper fitting before gently loosening the lower fitting followed by removal of four bolts which detach the throttle body adapter. First disconnect and remove the positive crankcase ventilation hose then move the power steering reservoir next to each other after taking out its upper and lower bolts followed by disconnecting the eight fuel injectors and removing the eight ignition coils. The generator must be removed after disconnecting the heater hose along with the radio interference capacitors and then following up with the removal of water thermostat and nine bolts to separate the upper intake manifold. The intake manifold should be lifted for access while you disconnect the intake manifold tuning valve connector before discarding both gaskets. Clean all gateway surfaces using a plastic scraper before installing the intake manifold tuning valve along with its attaching bolts. After placing new gaskets on the lower intake manifold, install the bolts to 2 Nm (18 inch lbs.) torque value followed by tightening to 10 Nm (89 inch lbs.). Place new gaskets onto the upper intake manifold before installing nine bolts loosely and connecting the electrical connector of the intake manifold tuning valve. The water thermostat installation requires two-staged bolt tightening as discussed before. You should join the generator electrical connections to the radio ignition interference capacitor while you also install the heater hose and the generator itself. Begin by putting the eight ignition coils into place and subsequent attachment of the eight fuel injector electrical connectors. Place back the power steering reservoir by tightening the two lower bolts and the upper one. You should install the throttle body adapter along with the PCV hose and the four bolts. The EGR valve must be reattached to the exhaust manifold tube with carefully applied hand torque on the fittings before completing bolt tightening. Attach the idle air control motor alongside all fuel lines and connect the brake booster vacuum line and its bracket before installing the retaining nut. Put back the differential pressure feedback EGR connections with all necessary vacuum lines to include vapor management valve vacuum line, throttle position sensor connector, fuel pressure regulator vacuum line, and engine vacuum regulator connector. Complete the main vacuum harness connection then place the accelerator cable bracket with bolts and reconnect the throttle body cam together with the accelerator cable and speed control actuator cable and throttle return spring. Put back the accelerator cable snow shield together with its bolts before linking the upper radiator hose with the proper clamp placement. Conclude the process by putting on the air cleaner system together with the outlet tube before reconnecting the battery ground wire and performing cooling system filling and bleeding.
