2005 Mercury Grand Marquis Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the intake manifold on 2005 Mercury Grand Marquis?

  A: The process for fixing the intake manifold requires you to start by removing the ground cable from the battery then emptying the engine cooling system. Start the service and repair by disconnecting the fuel spring lock coupling followed by removing the air cleaner combined with the outlet pipe. The starting point for intake manifold servicing requires removal of wiper mounting arm and pivot shaft followed by separate detachment of fuel charging wiring electrical connectors from eight ignition coils and eight fuel injectors. Service the exhaust gas recirculation (EGR) tube heat shield by removing all its mounting bolts then disconnect the electrical connector with its vacuum hoses that have attachments to the evaporative emissions (EVAP) canister purge valve. You must first disconnect the generator electrical connector prior to removing generator mounting bracket and its bolts. Start your detachment of the upper radiator hose before continuing with the throttle control and throttle position (TP) sensor electrical connectors and heater hose. The EGR system module tube requires disconnecting its nut before removing the exhaust manifold nut and extracting the EGR tube. The service technician effectively separates the wiring pin-type retainer from the crash bracket and disables crash bracket bolt assembly and finishes the process by extracting the stud. First disconnect both electrical connector and vacuum hose of the fuel pressure and temperature sensor. Also remove the generator harness position retainer from the LH front shed and the fuel charging wiring pin-type retainer from the rear of the manifold. Discontinue the power ground wire from both the RH rear manifold stud along with the coolant temperature sensor electrical connector. First detach eight ignition coils through their respective bolts and then remove the bolts and coolant outlet adapter. First remove the thermostat together with its O-ring before discarding both objects. Proceed by taking out the intake manifold bolts and the intake manifold gaskets while cleaning the sealing surfaces. The gasket locator tabs should be aligned with the cylinder head slots before putting on new intake manifold gaskets. Begin by installing the intake manifold while performing hand-torque on its bolts before installing the ignition coils and proceeding with bolt tightening. Begin by installing the crash bracket and its bolt but leave it loose before tightening the specified bolts as well as the stud. The EGR system module tube needs installation toward the EGR system module and the EGR tube nut requires installation to the exhaust manifold. Install the bolts on the EGR system module tube heat shield before connection of throttle control and TP sensor electrical connectors. Place the thermostat within the housing while adding the O-ring then fasten all housing bolts. The installation of an upper radiator hose requires exchanging hose clamps with the correct size of worm-style clamps. You should install the generator mounting bracket alongside its bolts before connecting the electrical connector to position the vacuum harness and joining vacuum hoses to the EVAP canister purge valve. The procedure requires connecting the electrical connector and vacuum hoses followed by installing the electrical connector and vacuum hose for the fuel pressure and temperature sensor. Reinstall the fuel charging wiring electrical connectors onto the eight fuel injectors and ignition coils while also adding the fuel charging wiring pin-type retainer at the manifold rear and placing the generator harness position retainer onto the LH front stud. Connect the pin-type retainer for fuel charging wire to the crash bracket and attach the ground wire connector to the RH rear stud and the coolant temperature sensor electrical connector. Ending the installation process includes fitting the wiper mounting arm and pivot shaft while reinstating the fuel spring lock coupling followed by air cleaner and outlet pipe installation before reconnecting the ground cable to the battery and completing the engine cooling system fill-up and bleeding operation.
