Mopar 68234997AB Exhaust And Catalytic Converter

Start by raising the vehicle and securing it on jackstands. If applicable, spray penetrating oil on nuts and bolts for easier loosening. For 2.4L engines (2014 and earlier), remove the oxygen sensor and rear portion of the exhaust system, then detach the converter from the exhaust manifold. For 2.7L engines, remove the front exhaust manifold/catalytic converter by disconnecting oxygen sensors and other components. For rear exhaust manifold/catalytic converter, remove the engine cover, splash shield, crossunder pipe, and oxygen sensors. For 3.5L engines, remove the front and rear exhaust manifold/catalytic converters by disconnecting oxygen sensors and other fasteners. For 3.6L engines, remove the rear catalytic converter by loosening clamps and fasteners, then guide the converter out from the bottom. Before installing the converter, use anti-seize compound on threads and tighten the fasteners securely. Installation is the reverse of removal for all models.

Inspect the exhaust manifold for cracks or damage, replacing it if necessary, and clean the threads of the mounting bolts, replacing any that are damaged.

Disconnect the oxygen sensor electrical connectors and remove the sensors.
