Removal Procedure
- Turn the ignition OFF.
- Disconnect the O2S-1 harness connector.
- Use a liquid penetrate before removing the sensor.
- Remove the O2S-1.
Notice: 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.
Important: 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.
Caution: 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 and will decrease the chance of exhaust pipe thread damage.
Installation Procedure
- Apply anti-seize compound Saturn P/N 21485279 (or equivalent) to the threads of the O2S-1.
- Install the O2S-1 in the exhaust manifold.
- Connect the O2S-1 harness connector. Push in the connector until a click is heard and pull back to confirm a positive engagement.
Notice: Refer to Fastener Notice in the Preface section.
Notice: Silicone products will damage the O2S-1. Use only nickel based anti-seize compound that does not contain silicone.
Tighten
Tighten the oxygen sensor to 45 N·m (33 lb ft).
Important: 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.
