2002 Ford E-250 Econoline Intake Manifold Parts Questions & Experts Answers

• Q: How to service the lower intake manifold on 2002 Ford E-250 Econoline?

  A: A vehicle technician must start the lower intake manifold service by taking out the intake manifold spacer assembly followed by disconnecting the EGR valve vacuum hose. The upper fitting of the EGR valve tube first requires removal followed by disconnecting the radiator upper hose from the lower intake manifold while also separating the water bypass hose from the heater water hose. Strict attention must be given to components connected to fuel since highly flammable fuel mixtures exist requiring removal of the fuel lines and fuel injector electrical connectors. The procedure also requires disconnecting the fuel injector electrical harness from both the fuel injector supply manifold and IMRC electrical connector and fuel pressure regulator vacuum line. All components of the fuel charging system together with the IMRC will be detached with the removal of the lower intake manifold. To replace the lower intake manifold the integrated manifold air recovery control system must be taken off. Before removing the lower intake manifold you need to remove the bolts which include a long one and a short one. Discard the sealing components consisting of the left and right intake manifold gaskets alongside the rear end seal and the front end seal. Start by applying sealant to the mounting points of the front and rear end seals. After that, install both end seals and set the intake manifold gaskets on the appropriate locations. Sealant application to the mounting points of the lower intake manifold needs to occur within fifteen minutes before installing it while positioning it properly. The installation of long and short bolts requires a two-step process whereby you tighten them first to 5 Nm (44 inch lbs.) followed by 10 Nm (89 inch lbs.). Connect all fuel lines after which you must complete the installation of the fuel pressure regulator vacuum line and the IMRC electrical connector. Securely attach both the upper radiator hose to the lower intake manifold as well as the EGR valve vacuum hose while installing the EGR valve tube upper fitting. First establish a connection between the heater water hose and the water bypass hose then the fuel injector electrical harness with the fuel injector supply manifold and electrical connectors. Conclude the installation by adding the intake manifold spacer assembly.
