The oxygen sensor may be difficult to remove when the engine temperature is below 120°F (48°C). Excessive force may damage the threads in the exhaust manifold of exhaust pipe.

1. Start the engine and let it warm up to 120°F (48°C), stop the engine and disconnect the negative battery cable.
2. Detach the electrical connector from the oxygen sensor.
3. Using a special, oxygen sensor socket, remove the oxygen sensor from the exhaust manifold or exhaust pipe.

1. Coat the threads of the oxygen sensor with anti-seize compound 5613695 or equivalent.
2. Install the sensor and tighten it to 30 ft. lbs. (40 Nm).
3. Reattach the electrical connector to the sensor and the negative battery cable.
