    Q:
    How to replace the exhaust heat shield for the catalytic converter on Buick LaCrosse? Posted by Customer
    A:
    The replacement process for Catalytic Converter heat shields starts by lifting the vehicle while maintaining its support. Exhaust system support must be implemented to avoid any movement. Start by taking off the Catalytic Converter followed by disconnecting the oxygen sensor wiring harness from its position on the heat shield. Begin by taking out the rivets holding the heat shield in place before extracting the heat shield piece. To install the new shield nonatomically position it in position then use rivets to secure it into place. Return oxygen sensor wiring harness to the heat shield followed by reinstallation of the Catalytic Converter. Test your vehicle's exhaust system and underbody for leaks when you remove the support then inspect the system for contact before letting your vehicle down.
