A failing or damaged catalytic converter can adversely affect the emissions your vehicle produces. In some states, a failing catalytic converter can cause the vehicle to fail inspection. However, most owners can change the catalytic converter with a few simple tools and a little automotive knowledge. The repair can be done within a hour. Before working on the exhaust system, let the car sit for a hour to ensure the exhaust system has completely cooled.
Tools Used: Tools, Automotive jack, Jack stands, PB Blaster, Wrench set
Replace Catalytic Converter
Lift the front of the vehicle with an automotive jack. Slide jack stands under the vehicle, positioning them under the frame rails to secure the vehicle while working underneath it.
Spray PB Blaster on the two bolts securing the catalytic converter to the center exhaust pipe, the two bolts holding the converter to the front exhaust pipe and the two bolts holding the converter support bracket to the body.
