REMOVAL
NOTE: The oxygen sensor uses a permanently attached pigtail and connector. This pigtail should not be removed from the oxygen sensor. Damage or removal of the pigtail or connector could affect proper operation of the oxygen sensor.
1. Turn ignition Off.
2. Disconnect electrical connector at the oxygen sensor.
3. Use a liquid penetrate before removing sensor.
NOTE:
^ Removal of the sensor is easier if the exhaust system is warmed up slightly. Be careful that it is not too hot to work on safely. Various types of penetrating oils applied to the threads while moving the sensor back and forth will also aid in removal.
^ Do not allow penetrating oils to contact the upper (air reference) portion of the sensor. This is the area between the hex and lead wires.
4. Remove oxygen sensor.
INSTALLATION
NOTE: Silicone products will damage oxygen sensor. Use only nickle based anti-seize compound that does not contain silicone.
1. Apply anti-seize compound Saturn PIN 21485279 (or equivalent) to the threads of the oxygen sensor.
2. Install oxygen sensor in exhaust manifold.
Torque: 30 N.m (22 ft-lbs)
NOTE: Take care when handling the oxygen sensor, it should not be dropped or roughly handled. The attached pigtail and connector and the louvered end must be kept free of dirt, grease or other contaminants. Avoid using cleaning solvents of any type.
3. Connect the electrical connector at the oxygen sensor. Push until a click is heard.
