How to Access and Replace the Lower Intake Manifold on a Buick Regal?

The process begins with upper Intake Manifold removal followed by generator brace then drive belt tensioner with mounting bracket and heater water bypass inlet pipe extraction. The installation sequence begins by first removing the exhaust gas recirculation (EGR) outlet pipe from both the lower Intake Manifold and afterward removing the radiator inlet hose from its water outlet housing position and disconnecting the engine coolant temperature (ECT) sensor electrical connection. Starting with the generator brace brackets' bolts and bracket removal, move to remove the evaporative emissions canister purge solenoid valve. First remove all bolts from the lower Intake Manifold while also taking out the manifold and gaskets and seals. Manifold replacement requires complete water outlet housing bolt and stud removal together with the housing, gasket, and Thermostat, and ect sensor removal. Evaluate the uniformity of inlet flange surfaces then clean both bolted surfaces and Intake Manifold attachment points from adhesive remnants. The ect sensor installation requires 25 nm torque (18 ft. Lbs.) following reinstallation. You should mount the water outlet housing and its bolts and stud while maintaining a torque of 27 nm (20 ft. Lbs.). Prior to installing the lower Intake Manifold gaskets apply gm p/n 12346286 sealer or equivalent to their ends then install the gaskets and manifold. Use thread lock gm p/n 12345382 or equivalent on the two concealed bolts and tighten each of the 12 lower Intake Manifold bolts in sequential order to 15 nm (11 ft. Lbs.). Reroute the evaporative emissions canister purge solenoid valve followed by the generator brace bracket connected with bracket bolts tightened to 50 nm (37 ft. Lbs.). Reconnect the ect sensor electrical connector and install the radiator inlet hose onto the water outlet housing. You should then attach the egr outlet pipe to the lower Intake Manifold and tighten the bolt to 29 nm (21 ft. Lbs.). To complete the repair install the drive belt tensioner and generator brace and upper Intake Manifold.
