Oxygen Sensor 1 (O2S-1)




REMOVAL

NOTE: The O2S-1 uses a permanently attached pigtail and connector. This pigtail should not be removed from the O2S-1. Damage or removal of the pigtail or connector could affect proper operation of the O2S-1.

1. Ignition Off.
2. Disconnect O2S-1 harness connector.
3. Use a liquid penetrate before removing sensor.
4. Remove O2S-1.

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. Applying penetrating oil 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.


INSTALLATION
1. Apply anti-seize compound Saturn P/N 21485279 (or equivalent) to the threads of the O2S-1.

NOTE: Silicone products will damage the O2S-1. Use only nickle based anti-seize compound that does not contain silicone.

2. Install 02S-1 in exhaust manifold.

Torque: 45 N.m (33 ft-lbs)

3. Connect O2S-1 harness connector. Push until a click is heard and pull back to confirm a positive engagement.

NOTE: 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.
