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.

In the Buick Regal vehicles' systems, the Intake Manifold is instrumental in admission of air or air/fuel mixture into each cylinder head intake port thereby determining power and performance. In prior designs, the manifold was made of cast iron or aluminum; however, the current models are mostly small and lightweight plastic for better fuel economy and heat. Some manifolds have upper and lower halves having gaskets, coolant passages, and sensors used by the engine to regulate the car. Original equipment manifolds are comparatively less efficient as they do not have runner shapes, materials and configurations that are inherent with an manifold which means they generate more horsepower and torque. Therefore, through change of aluminum manifold, drivers can get improved airflow and dispersion if there is an addition of an engine modification. As with long intake manifolds, variable-length intake manifolds consequently improves power, torque, and fuel efficiency with the use of speed and pressure of airflow depending on the load condition; resulting to more efficient and powerful engines.
