How to replace the upper intake manifold on Buick LaCrosse?

Start by turning off ignition power before removing the air inlet duct. The fuel system needs to have pressure relieved using ch 48027 either manually or automatically followed by disconnecting pressure and evaporative emission hoses at the engine using metal collar quick connect fitting service and plastic collar quick connect fitting service. Mishandling of the purge line needs removal from its retainer, and the fuel feed hose bracket bolt, with no need to disconnect the ecm electrical connectors during fuel feed hose repositioning. Start by removing the ecm bracket with its-based unit before you disconnect the purge solenoid electrical connection and extract the wiring harness from the right side of the Intake Manifold. Start by disconnecting the Fuel Injector electrical connector from its bracket before moving on to the Throttle Body electrical connector and next removing the Brake Booster Vacuum Hose and check valve and baro sensor electrical connector and finally the positive crankcase ventilation (PCV) hose. The upper Intake Manifold needs removal by extracting the Intake Manifold bolts (1-6) and discarding the upper Intake Manifold gasket. Clean and inspect both the Intake Manifold and all sealing surfaces when disassembly becomes required. To install the manifold begin by constructing and installing it while screwing down the Intake Manifold bolts (1-6) at 23 n.m (17 lb ft) following the specified sequence. Reinstall the pcv hose and Brake Booster Vacuum Hose and check valve together with the Throttle Body electrical connector and baro sensor electrical connector. First install the wiring harness and bracket on the right side of the Intake Manifold after you connect the Fuel Injector electrical connector to both the injector itself and the bracket. Tighten the bracket bolts to 10 n.m (89 lb in). Reinstall the purge solenoid electrical connector while placing the ecm bracket with its ecm component in position. Secure the fuel feed hose bracket and bolt into place with 10 n.m (89 lb in) torque.
