    Q:
    What is the procedure for replacing the Catalytic Converter in the 1998 Pontiac Grand Prix? Posted by Ashok S.
    A:
    For other models, the car should be raised and securely supported on jack stands. Then, the converter should be unbolted from the manifold and intermediate exhaust pipe before removal. Installation follows the reverse order of removal. You can Select Your Vehicle to see complete installation and repair tips.
