2004 Cadillac Escalade EXT Catalytic Converter

When replacing the engine, ALL transferred components should be performed. Any debris found should be removed. In cases of engine failure due to severe overheating dealers should also inspect each catalytic converter for signs of melting or cracking of the ceramic °brick°. If damage is observed the converter should be replaced.

The recommended bolt torque is 42 Nm (31 ft. lbs.).

This may result in ceramic debris being drawn into the engine through the cylinder head exhaust ports. If a replacement engine is installed in either of these instances the replacement engine may fail due to the debris being introduced into the combustion chambers when started.

You need to Raise and suitably support the vehicle, remove the muffler, disconnect the Connector Position Assurance retainers and the oxygen sensor electrical connectors, remove the left exhaust manifold pipe nuts and the catalytic converter, slide the catalytic converter hanger out of the exhaust pipe hanger bracket, and remove the oxygen sensors if the catalytic converter is to be replaced.
