2001 Mercury Villager Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the lower intake manifold on 2001 Mercury Villager?

  A: A service or repair operation on the lower intake manifold requires a prior step of releasing fuel system pressure. You need to remove both the upper intake manifold alongside all electromagnetic connectors specifically the fuel injector ones and Engine Coolant Temperature sensor connector. Disconnect the H02S heated oxygen sensor electrical connector by removing ground wire bolts and removing the wire harness from its bracket. Reposition the Positive Crankcase Ventilation (PCV) breather tube while removing its wire harness by unclamping the hose and detaching the PCV breather hose before removing the wire straps. Disconnect the water temperature indicator sender electrical connector while removing the spark plug wire bracket through its bolt removal. Prior to handling fuel-related sections exercise caution because the mixtures contain highly flammable elements while pressure relief on fuel system components requires unbolting the fuel lines and unclamping and disconnecting them. The fuel injection supply manifold must have its insulators eliminated before extracting the manifold using bolt removal. The radiator hose upper section requires release of its bolt and clamp to position it aside. Unscrew the upper timing belt cover bolt followed by disconnecting the coolant bypass hose from the water hose connection after loosening its clamp then releasing the heater hose from the heater hose pipe with the same method. Follow the specified sequence when you use a two-step method to take out lower intake manifold bolts and nuts before discarding the gaskets. Remove the lower intake manifold after this operation. Alignment of the lower intake manifold gaskets and lower intake manifold begins installation. Fasten the bolts and nuts in order while tightening them to 4 Nm (35 inch lbs.) at the first stage followed by 9 Nm (80 inch lbs.) in stages two and three. Install the heater hose onto the heater hose pipe then install the clamp afterward and complete the same process for both the coolant bypass hose to the water hose connection and its clamp. The upper timing belt cover bolt must be installed first before hooking up the upper radiator hose and tightening the clamp before putting its bolt. Mount the fuel injection supply manifold to its position after installing its insulating components. Then install all supply manifold bolts. The fuel lines need installation in three stages which start with positioning the fuel line followed by bolt installation then moving to connect the fuel hose before installing the clamp. The installation of the spark plug wire bracket bolt happens while connecting the water temperature indicator sender electrical connector and positioning the PCV breather tube and wire harness for PCV breather hose connection and installation of new wire straps. The process begins by connecting the H02S electrical connector while the wire harness gets attached to the bracket through ground wire bolt installation. Install the upper intake manifold by connecting all electrical fuel injector and ECT sensor connectors.
