2001 Ford E-250 Econoline Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the lower intake manifold on 2001 Ford E-250 Econoline?

  A: A service or repair operation of the lower intake manifold starts with the removal of the intake manifold spacer assembly followed by disconnecting the EGR valve vacuum hose. The service begins with removing the upper fitting of the EGR valve tube after which you disconnect the radiator upper hose from the lower intake manifold and the water bypass hose and heater water hose. Heavily combustible fuel mixtures exist within the system thus you must disconnect all fuel lines and electrical connectors of the fuel injectors. Thirdly remove the fuel injector electrical harness from both the fuel injector supply manifold and the IMRC electrical connector and the fuel pressure regulator vacuum line. All components related to fuel charging and IMRC will be extracted along with the lower intake manifold. The IMRC needs to be extracted together with any lower intake manifold replacement. The next step involves removing both long and short lower intake bolts before taking out and discarding sealing components including left and right intake manifold gaskets and the front end together with the rear end seal. Begin by applying sealant to the front and rear end seal mounting points of the intake manifold before installing both end seals followed by placing the gaskets. Correctly position the lower intake manifold during the fifteenth-minute period after applying sealant and distribute the sealant coat on mounting points. The installation requires you to position both bolts at their correct places before tightening them at two different torque levels of 5 Nm (44 inch lbs.) and then 10 Nm (89 inch lbs.). Technical team members will reconnect the fuel lines and fuel pressure regulator vacuum line together with the IMRC electrical connector. Proceed with installing the upper radiator hose onto the lower intake manifold then connect the EGR valve vacuum hose and assemble the EGR valve tube upper fitting. To conclude the repair work connect the water bypass hose with the heater water hose then attach the fuel injector electrical harness to the fuel injector supply manifold before installing the intake manifold spacer assembly while connecting the fuel injector electrical connectors.
