Catalytic Converter: Service and Repair
Catalytic Converter Replacement (RWD)
Removal Procedure
Caution: Always wear protective goggles and gloves when removing exhaust parts as falling rust and sharp edges from worn exhaust
components could result in serious personal injury.
Caution: In order to avoid being burned, do not service the exhaust system while it is still hot. Service the system when it is cool. An
accumulation of dirt and corrosion may make removing exhaust components difficult. Applying a penetrating oil on the threads of the bolts
may assist in the removal of these components.
1. Raise the vehicle. Refer to Vehicle Lifting.
2. Support the catalytic converter assembly.
3. Remove the 3 oxygen sensor electrical connections and clips.
4. Remove the nuts from the muffler flange bolts.
