  Q: How to service the intake manifold on Mercury Milan?

  A:

  The service procedure for the intake manifold begins with hoisting the vehicle in neutral mode while disconnecting the battery ground cable. The procedure starts with removing the air cleaner outlet pipe followed by disassembly of the two nuts and bolt from the generator air inlet duct which needs a torque of 6 Nm (53 lb-inch) for reinstalling. Use the locking ring depressors to disconnect both brake booster vacuum tube and evaporative emissions (EVAP) tube from their intake manifold connections. Remove the fuel rail insulator from the engine compartment by first disconnecting both swirl control valve electrical connectors and detaching the two wiring harness pin-type retainers. Detach the electrical connector pin-type retainer along with removing seven screws that secure the underbody cover when installed. Manual transaxle vehicles need two bolts removed to position the Clutch Slave Cylinder aside and the bolts get tightened at 22 Nm (16 lb-ft) when reinstalled. Before installing the air pump return to service, vehicles with air need users to disconnect their electrical connector first then detach three securing bolts before setting the pump aside with a torque of 30 Nm (22 lb-ft). After disconnecting the vacuum hose from the intake manifold remove the radiator hose retaining clip followed by the intake manifold lower bolt installation with a torque of 18 Nm (13 lb-ft). You need to separate and remove the manifold absolute pressure (MAP) sensor wiring harness pin-type retainer along with engine oil pressure (EOP) switch electrical connector and intake manifold runner control (IMRC) actuator from their respective plugs. Position the wiring harness to the side. During reinstallation of the Starter connect the S-terminal wire along with the nut which requires a torque of 12 Nm (9 lb-ft). Proceed by disconnecting the Throttle Body electrical connector then discard the gasket before removing its four bolts for placement aside and ensure proper torque of 10 Nm during reinstallation. First detach both pin-type retainers from the intake manifold by observing its different bolt sizes for future installation. Next remove the seven bolts to set the intake manifold aside so you can reach and tighten the crankcase vent hose clamp and EGR Tube to 18 Nm (13 lb-ft). The crankcase vent hose requires release of the clamp to begin the disconnection process after which you should detach the Knock Sensor electrical connector pin-type retainer along with removing the EGR tube. Reinstallation should be executed with a torque of 55 Nm (41 lb-ft). To complete the task remove the intake manifold before discarding both gaskets then reinstall everything in reverse order while using new gaskets for the TB and intake manifold.
