2004 Mercury Sable Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the lower intake manifold on 2004 Mercury Sable?

  A: A service and repair operation on the lower intake manifold starts with draining engine coolant then disconnecting the fuel tube spring lock coupling. Start the service by disconnecting and moving the upper intake manifold and then the left-hand and right-hand valve covers. The service process requires discretion of FRP sensor vacuum connections alongside electrical interfaces and fuel injector electrical connectors. In the first step remove the fuel injection supply manifold together with fuel injectors as an assembly followed by disconnecting the heater hose and separating the Engine Coolant Temperature (ECT) sender's electrical connector and ECT sensor's electrical connector and degas bottle hose. To continue the procedure remove the Camshaft Position (CMP) sensor after disconnecting the upper radiator hose from the thermostat housing. The lower intake manifold bolts need removal until the intake manifold gaskets and end seals can be extracted. A metal surface cleaning agent should clean all surfaces which need sealing before installation. You need to remove both the sealant and cleaning the sealing area once again if the lower intake manifold does not secure within four minutes and you must allow it to dry totally before repeating the process. The installation requires silicone treatment at the four cylinder block-to-cylinder head seams followed by proper placement of lower intake manifold gaskets and end seals. The intake manifold needs installation with an odd-even bolt tightening approach starting at 15 Nm (11 ft. lbs.) and proceeding to 32 Nm (24 ft. lbs.). Reinstall the CMP sensor and implement the upper radiator hose into the thermostat housing along with reconnecting both ECT sensor electrical connector and degas bottle hose. Install the heater hose and ECT sender electrical connector before you place the fuel injection supply manifold along with its fuel injectors in their proper assembly. Connect both fuel injector electrical connectors before you join the electrical and vacuum connections of the FRP sensor. The last steps involve installing both valve covers together with the upper intake manifold and reconnecting the fuel tube spring lock coupling prior to performing engine cooling system filling and bleeding.
