2007 Ford Crown Victoria Intake Manifold Parts Questions & Experts Answers

• Q: How to service the intake manifold on 2007 Ford Crown Victoria?

  A: The intake manifold servicing process starts with independent operation of the fire suppression system (if installed) while hoisting the vehicle at a neutral position. Binary connection of the fuel tube spring lock coupling must happen together with battery ground cable removal and engine cooling system draining. Serious servicing starts by removing both the wiper mounting arm and outlet pipe combined with pivot shaft and air cleaner. The eight fuel injector electrical connectors join eight ignition coil-on-plugs for removal. The maintenance process begins with removing two bolts that secure the intake manifold shield followed by shedding the shield and continuing to disconnect the brake booster vacuum hose along with all quick connect EVAP canister purge valve hoses and the positive crankcase ventilation (PCV) tube from the throttle body spacer. The EGR system module needs its vacuum and electrical connectors cut along with the intake manifold-to-throttle body spacer vacuum hose and electrical generator connector. The four generator bracket bolts need removal along with the bracket to access the coolant thermostat. Remove the electric connections of the throttle control and throttle position (TP) sensor while releasing the heater hose spring clamp and removing the heater hose. Begin by taking out the EGR system module tube then detach the wire harness retainer from the intake manifold crash bracket if available before removing the crash bracket bolts without allowing them to touch the cylinder head. The technician disconnects both the fuel rail pressure and temperature sensor vacuum and electrical connectors before removing the wire harness retainers from the left-hand front fuel rail stud and the rear of the intake manifold. First detach the ground connector from the right-hand rear fuel rail stud bolt and afterward remove the eight bolts securing the intake manifold along with wasting the gaskets. Prepare the sealing surfaces by cleaning them and position new intake manifold gaskets properly to match the slots from the cylinder head. The eight bolts of the intake manifold should be hand-tightened first while the eight ignition coil-on-plugs can be adjusted last. Place the new intake manifold crash bracket followed by a loose installation of the bolt and stud bolt and finish by torquing all bolts to 25 Nm (18 ft. lbs.) through the given sequence. First, apply the same torque value to the crash bracket bolt before adding the EGR system module tube and intake manifold shield with two bolts which need to be tightened to 12 Nm (9 ft. lbs.). The throttle control and TP sensor electrical connectors should be attached first before installing the coolant thermostat as well as the generator bracket with four bolts fastened to 10 Nm torque (89 inch lbs.). Reattach the generator electric connection and mount the EVAP canister purge hoses from the throttle body to EVAP canister purge valve before connecting the intake vacuum hose to the throttle body spacer including the EGR system module's vacuum and power links. Connect the PCV tube quick connect coupling to the throttle body spacer while installing brake booster vacuum hose to the intake manifold and heater hose accompanied by its spring clamp. To proceed with the repair work, begin by reconnecting the vacuum and electrical connectors of the fuel rail pressure and temperature sensor and then move to the eight fuel injector electrical connectors. Insert the wire harness retainer at the intake manifold rear side then connect it to the left-hand front fuel rail stud. The wire harness retainer should be mounted to the intake manifold crash bracket then a ground connector should be attached to the right-hand rear fuel rail stud bolt. The last installation steps include reassembling the wiper mounting arm and pivot shaft together with connecting the fuel spring lock coupling followed by air cleaner and outlet pipe installation and grounding the battery and filling the engine cooling system for bleeding. A repowered fire suppression system requires activation for this step.
