• Q: How to Service and Repair an Intake Manifold on 2001 Ford Explorer?

  A: One should start by draining engine coolant along with separating the radiator overflow hose for lower intake manifold servicing work. First disconnect the water heater tube from the water bypass hose then remove the upper intake manifold followed by the engine coolant temperature (ECT) electrical connector. First disconnect the heater water hoses together with the PCV heater hoses from the water heater tube while removing the wire harness retainer nut. Proceed by disconnecting the upper radiator hose and you must also remove the water bypass hose using the clamps. The first step involves cutting the connections for eight fuel injector electrical connectors along with the fuel line followed by disconnecting the ground strap at the back of the lower intake manifold and the water temperature indicator sender electrical connector. The first step involves taking out the CMP sensor together with the camshaft synchronizer and unfastening the bolts to extract the lower intake manifold. Discard the lower gasket during this procedure. For installation, clean the gasket surfaces of the lower intake manifold, cylinder heads, and cylinder block using Metal Surface Cleaner F4AZ-19A536-RA or an equivalent that meets Ford specification WSE-M5B392-A. Apply a 1.6 mm (0.06) bead of Silicone Gasket and Sealant F7AZ-19554-EA or an equivalent that meets Ford specification WSE-M4G323-A4 in the corners where the cylinder head and cylinder block meet, then position the four lower gaskets, ensuring the intake manifold seal tabs fit into the notches of the lower intake manifold gaskets. Press along the entire intake manifold seal to make silicone sealant appear before placing the lower intake manifold and starting the bolts. The installation of lower intake manifold requires a two-step procedure where initial pressure reaches 10 Nm (89 inch lbs.) before advancing to 32 Nm (24 ft. lbs.). After reinstalling the camshaft position (CMP) sensor along with the camshaft synchronizer, reconnect the rear ground strap as well as the water temperature indicator sender electrical connector and eight fuel injector electrical connectors. First attach the fuel line followed by mounting the water bypass hose through its two clamps before installing the upper radiator hose and heater water hoses and wire harness retainer nut. The last sequence includes engine coolant temperature (ECT) electrical connector connection along with the water heater bypass hose attachment to heater tube, two PCV heater hoses securement to heater tube followed by upper intake manifold installation and radiator overflow hose reconnection before engine cooling system filling.
