• Q: How to replace the right exhaust manifold on 2000 Buick Regal?

  A: The replacement of the right Exhaust Manifold begins with disconnecting the battery ground cable. Proceed with removal of the right Exhaust Manifold by first removing its fuel injector sight shield followed by the exhaust crossover pipe. First lift the vehicle before removing the egr adapter pipe along with three way Catalytic Converter from the right Exhaust Manifold. The installer must remove clips from the heater hose and wiring harness before detaching them from the fuel injector sight shield bracket followed by right spark plug wire removal. First separate the right engine lift bracket bolt and nut before taking aside the bracket itself. Begin by unplugging the fuel injector sight shield bracket nuts before removing both the bracket and nuts. Keep the Oxygen Sensor's bolt in place by removing all remaining right Exhaust Manifold bolts and nuts. Lower the vehicle before rotating the engine to reach its desired position. Begin by detaching the Oxygen Sensor electrical connector before removing the last connector and the right Exhaust Manifold including its gasket. Remove both the right Exhaust Manifold heat shields while extracting the heated Oxygen Sensor from this section of the exhaust system with necessary replacement of any defective Exhaust Manifold studs. Begin the installation process with Exhaust Manifold stud(s) replacement if extracted and then install the heated Oxygen Sensor. Install new right Exhaust Manifold Gasket before assembling the right Exhaust Manifold and its upper and lower heat shields. The Exhaust Manifold bolt should be mounted behind the Oxygen Sensor while reconnecting its electrical connector. Putting the engine back where it started the process then raising the vehicle allows you to fasten the remaining right Exhaust Manifold bolts and nuts using 30 nm and 22 ft. Lbs. Torque settings. After placing the fuel injector sight shield bracket along with its nuts you must torque them to 30 nm (22 ft. Lbs.). Return the right engine lift bracket to its position and fasten it with a bolt and nut which requires tightening to 30 nm (22 ft. Lbs.). Secure the right Spark Plug Wires before adding wiring harness together with heater hose retaining clips onto the fuel injector sight shield bracket. Secure the three way Catalytic Converter to its position on the right Exhaust Manifold only after checking for leaks in the egr pipe outlet if you disconnected the egr pipe. Seal the egr pipe into the right Exhaust Manifold by torquing the egr pipe bolt to 29 nm (21 ft. Lbs.). After lowering the vehicle you should install the exhaust crossover pipe to the right Exhaust Manifold and reinstall the fuel injector sight shield. Fasten the negative cable for the battery ground.
