How to replace the oxidation catalytic converter on 2009 Buick Lucerne?

The installation process starts with vehicle elevation alongside supporting measures. Make a mark 36 mm (1.4 in) behind the oxidation Catalytic Converter weld on the outlet pipe before making a cut. You need to cut the converter outlet pipe at its marked cut point following removal of oxidation Catalytic Converter to Muffler assembly nuts. You must move the Muffler assembly gently toward the rear for clearance before extracting the oxidation Catalytic Converter off the vehicle and tossing out the gasket. Upon installation users should slide 2 service clamps around the oxidation Catalytic Converter outlet pipe while avoiding any tightening force. Install a fresh mating gasket between both catalytic converters while possibly needing to lower your exhaust system for the converter-to-Muffler connection. Position the oxidation Catalytic Converter between the three-way Catalytic Converter and Muffler assembly before applying 47 nm (35 lb ft) of torque to the nuts. Position each clamp at the middle of the Catalytic Converter output pipe yet direct their ends toward opposite directions before bringing them together as closely as feasible. Check that the oxidation Catalytic Converter fits properly to the Muffler assembly before tightening the clamps to 54 nm (40 lb ft). After finishing installation lower the vehicle to inspect exhaust leaks.
