  Q: How to Properly Install an Intake Manifold on a Mercury Grand Marquis?

  A: Position the gasket tabs exactly on the slots of the block before installing new intake manifold gaskets. Check that the gasket tabs align with the slots of the block then position the intake manifold before applying a hand torque on its specified mounting bolts. Start by installing eight Ignition Coils which require equivalent eight bolt tightening before adding and securing the fuel injection supply manifold to four studs. The procedure begins with installing the crash bracket bolt and stud in a loose manner followed by water Thermostat and water outlet adapter bolt attachment with loose tightening. The coolant sensor connector should be connected alongside the fuel charging wiring harness position retainer near the back of the intake manifold. Following this step tighten the bolts according to the specified sequence while fastening the stud. The cables should be connected to the crash bracket which requires bolt tightening before you install and tighten the Throttle Body. Install the nut and bolt while positioning the wiring bracket and connect wiring connectors to the bracket which should include the LH heated oxygen sensor electrical connector. One must install the EGR tube to the EGR Valve after attaching the fuel charging wiring harness pin-type retainer to the crash bracket. Install the EGR tube heat shield while securing its bolts followed by wiring up the ground connector at the RH rear stud. After attaching the heater water hose the clamp must be positioned before connecting electrical connectors to both IAC control valve and TP sensor. Put the upper radiator hose in position before placing the clamps in place and then mount and bolt the generator bracket. Install the generator harness position retainer to the LH front studs while connecting the generator electrical connector, cable and harness pin-type retainer. First position the vacuum harness before connecting it to the EVAP Canister Purge Valve and mains and EGR vacuum regulator solenoid through wires. Begin with attaching the PCV tube before installing the vacuum harness between the EVAP canister purge valve and main chassis vacuum supply line and EGR valve. Attach the cables to the EGR tube heat shield before you proceed to connect the Accelerator Cable with the speed control actuator cable and throttle return spring. Wire the electrical connectors of fuel charging to all eight Fuel Injectors and ignition coils as well as the electrical connectors of differential pressure feedback EGR. When executing this step, raise the vehicle to install the EGR tube onto the Exhaust Manifold and join electrical connectors to the PSP switch and the oil pressure sensor while adding the oil bypass filter. Secure the pin-type retainer on the A/C compressor bracket after connecting its electrical connector between the A/C compressor and CKP sensor. After installation of the RH Catalytic Converter assembly proceed with lowering the vehicle along with Drive Belt installation. Insert the wiper mounting arm with pivot shaft and then fit the fuel line before installing the air cleaner outlet tube. Add the battery ground cable before inspecting engine oil and completing the engine cooling system filling procedure.
