• Q: How to Service and Repair an Intake Manifold for Lower on 2002 Ford Mustang?

  A: The service and repair of the lower intake manifold becomes possible after removing the upper intake manifold together with partial coolant removal from the system. Start by draining fuel pressure from the system before disconnecting both the vacuum tube and electrical wiring of the fuel pressure sensor followed by fuel injection supply manifold separation. Users must first position the engine wire harness to the side before removing the electrical connector of the Intake Manifold Runner Control (IMRC) actuator. The next operation requires uninstalling the heater bypass tube and heater hose and EGR vacuum tube and EGR tube and coolant hoses with upper radiator hose and water bypass hose. The maintenance specialist disconnects the electrical connector before removing the fuel injection supply manifold and fuel injectors together as one unit while remembering how the short and long bolts should fit back during reassembly. Take out the lower intake manifold by removing eight short bolts and six long bolts which should be discarded together with the intake manifold gaskets. Installation begins by putting silicone gasket and sealant along front and rear end seal mounting points after end seals and intake manifold gaskets get installed. The installation of the lower intake manifold requires that the sealant application process takes no longer than four minutes. Then, position the manifold before sealing the mounting points with silicone gasket and sealant. Use the following two-step procedure to tighten bolts: apply 5 Nm (44 inch lbs.) and then 10 Nm (89 inch lbs.). Squeeze the fuel injection supply manifold together with its fuel injectors and reconnect their electrical connectors while also joining their corresponding coolant hoses, EGR tube and EGR vacuum tube. The assistance of water helps to lubricate the O-ring before the heater hose and heater bypass tube installation followed by IMRC actuator electrical connector connection and engine wire harness positioning with pin-type retainer attachment. The last steps include joining the fuel supply manifold with fuel pressure electrical connector and vacuum hose while installing the upper intake manifold prior to properly bleeding the cooling system for accurate engine cooling.
