2002 Mercury Grand Marquis Intake Manifold Parts Q&A

• Q: How to install the intake manifold and its associated components on 2002 Mercury Grand Marquis?

  A: Install the intake manifold by placing gasket tabs inside the block slots prior to adding new intake manifold gaskets. You should install the intake manifold before slowly tightening the specified bolts by hand. The next step involves placing eight ignition coils then tightening their bolts and after that comes the fuel injection supply manifold installation with four stud tightening. First position the crash bracket bolt along with the stud while the water thermostat and water outlet adapter bolts remain loose. Affix the coolant sensor connector along with the fuel charging wiring harness position retainer behind the intake manifold. Tighter bolts need to be installed in their specified sequence while the stud requires a final lock. Attach crash bracket cables then tighten their bolts before installing the throttle body with secured bolts. Secure the wiring bracket in position by installing the nut and bolt followed by wiring connector attachment and LH heated oxygen sensor electrical connector connection. The pin-type retainer of the fuel charging wiring harness needs attachment to the crash bracket while the EGR tube must be connected to the EGR valve. Install bolts on the EGR tube heat shield followed by attaching the ground connector at the RH rear stud position. Place the heater water hose while applying the clamp before plugging in both connection wires to the IAC control valve and TP sensor. First install the upper radiator hose along with clamps before installing the generator mounting bracket along its bolts. Connect the generator electrical connector along with its cable and pin-type retainer before installing the generator harness position retainer on the LH front studs. Position the vacuum harness and then link the vacuum hose to the EVAP canister purge valve before connecting its electrical connector alongside vacuum supply to the EGR vacuum regulator solenoid. The first process involves installing the PCV tube after which you must connect both the vacuum harness and vacuum hoses used on the EVAP canister purge valve and the main chassis vacuum supply line with the EGR valve. The cables require relocation onto the EGR tube heat shield then you should connect the accelerator cable alongside the speed control actuator cable and throttle return spring. Attach the eight fuel injector and ignition coil wiring electrical connectors together with the differential pressure feedback EGR electrical connectors. Before putting up the vehicle for installation of the EGR tube and exhaust manifold connection start with the PSP switch and oil pressure sensor electrical connector and end by installing the oil bypass filter. The electrical connector for the A/C compressor and CKP sensor must be joined followed by attachment of the pin-type retainer to the A/C compressor bracket. After installing the RH catalytic converter assembly proceed by lowering the vehicle to finish with the installation of the drive belt. Connect the fuel line before you install the air cleaner outlet tube and the wiper mounting arm alongside pivot shaft. The technician finishes by attaching the battery ground cable before testing the engine oil. They then complete the process by filling the engine cooling system.
