  Q: How to replace the Exhaust Hanger and Insulator from the converter to the transmission on Buick Rainier?

  A: Replacing the exhaust system insulator, hanger, and bracket from the converter to the transmission requires first raising the vehicle. First remove the heated Oxygen Sensor electrical connection before removing the nuts from the Catalytic Converter pipe-to-Exhaust Manifold connection and discard both the old exhaust seal and nuts. Start by removing the nuts which connect the Catalytic Converter pipe to the Muffler followed by the bolt anchoring the Exhaust Hanger to the transmission mount before taking out the transmission mount. The installation process begins by removing both the Catalytic Converter and Exhaust Hanger assembly before dissembling the Exhaust Hanger from the Catalytic Converter. First position the Catalytic Converter into the vehicle while installing the Exhaust Hanger to it then reinstall the assembly combined with the Catalytic Converter and Exhaust Hanger. Attach the transmission mount with a 30 nm (22 ft. Lbs.) bolt securing the Catalytic Converter pipe hanger right before reinstalling the transmission mount. Secure the Catalytic Converter pipe to the Exhaust Manifold with a new exhaust seal before evenly threading the nuts by hand against the exhaust flange until secure then tighten them to 50 nm (37 ft. Lbs.). Reconnect the h2os electrical connector after lowering the vehicle.
