The oxygen sensor has a permanently attached pig-tail and connector. This pig-tail should not be removed, since removal will affect proper operation of oxygen sensor.
1. Disconnect electrical connector from oxygen sensor.
2. Using a suitable wrench, carefully remove sensor from exhaust manifold or pipe. The oxygen sensor may be difficult to remove when engine temperature is below 120°F. Use caution, since excessive force may damage threads in exhaust manifold or pipe.
3. If new sensor is being used, install sensor into manifold or pipe.
4. If old sensor is being reused, coat threads with anti-seize compound, Part No. 5613695 or equivalent, then install into manifold or pipe.
5. Torque oxygen sensor to 30 ft. lbs., then reconnect electrical connector.
