    Q:
    How to replace a catalytic converter? Posted by Customer
    A:
    The following is a generalized procedure for most catalytic converters. The specifics vary among tile engines used in these vehicles. Many exhaust specialist shops are able to replace catalytic converters at a lower cost than what you might pay for a new one from a dealer.Raise the vehicle and support it securely on jackstands.Disconnect the electrical connector from the related oxygen sensor and remove the sensor.Support the other sections of the exhaust system as necessary.Remove the retaining nuts from the front and rear catalyst mounting flanges.Remove the catalyst and pull off the gaskets.Installation is the reverse of removal. Replace any rusted or damaged fasteners along with the gaskets.
