How to Maintain an Oxygen Sensor on 2004 Jeep Liberty?

First, allow the engine to cool, as these parts of the exhaust system get really hot during use. Support the vehicle and then carefully separate the wire from the O2S sensor, trying not to tug straight on the wire. Remove the O2S sensor with the help of a tool made for this job, then clean out the threads in the exhaust pipe using a recommended tap. Be mindful, the threads on the new sensor are already coated with anti-seize, so you shouldn't add any more. Install the O2S sensor and tighten to 30 Nm or 22 ft. lbs, then connect the wires before bringing the vehicle down.
