How to replace the exhaust heat shield for the catalytic converter on 2008 Buick LaCrosse?

A professional technique starts with properly lifting the vehicle using proper equipment and subsequently supporting the exhaust system before removing the Catalytic Converter. Support the exhaust system completely before starting the Catalytic Converter removal process. Start by disconnecting the oxygen sensor wiring harness from the Catalytic Converter heat shield and then remove the rivets holding on the heat shield before finally removing the shield itself. Secure the installation of your new Catalytic Converter heat shield by using rivets. Reinstall the Catalytic Converter by first reconnecting the oxygen sensor wiring harness to the heat shield. Review the exhaust system after removing support to check for leaks and underbody interference before lowering the vehicle.
