To replace the catalytic converters on various engine models, 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.

Raise the vehicle and remove the engine under cover, then detach the catalytic converter-to-exhaust manifold nuts, discarding the old gasket.

First, disconnect the negative battery cable from the remote ground terminal.

Remove all gasket material from mating surfaces carefully to avoid scratching, and inspect for warpage using a straightedge and feeler gauge; any excessive warpage requires replacement or resurfacing.

Position the exhaust manifold with a new gasket and install the mounting bolts finger tight, ensuring the gaskets are identified by the correct cylinder designation and exhaust port position.

The remainder of the installation follows the reverse order of removal. Finally, start the engine and check for exhaust leaks between the manifold and cylinder head as well as between the manifold and exhaust pipe.

Disconnect the oxygen sensor electrical connectors and remove the sensors.

Install the manifold and thread the mounting nuts, tightening them in three or four equal steps from the center out.

Disconnect the oxygen sensor wire.

A catalytic converter is an emission control device that reduces pollutants in the exhaust gas stream. There are two types of converters: the conventional oxidation catalyst and the three-way catalyst.

Clean the manifolds with solvent and dry them with compressed air, check the mating surfaces for flatness with a precision straightedge and feeler gauges, and inspect the manifolds for cracks and distortion, replacing or resurfacing them if necessary.
