- 1). Place a small amount of anti-seize on the threads of the O2 sensor.
- 2). Unscrew the old O2 sensor, located in front of or behind the catalytic converter, depending on the year of the Volvo. Place the new O2 sensor into the threaded hole.
- 3). Tighten the O2 sensor until you feel resistance. Do not force the O2 sensor into place or damage may occur to the threads on either the O2 sensor itself or the hole in the piping.
- 4). Connect the electrical connector to the O2 bung.
- 5). Verify that the sensor is functioning properly by turning on the vehicle. Wait for the "check engine" light to come on, then wait for it to turn off. If the "check engine" light cycles properly and does not come back on again after it goes out, the O2 sensor is functioning properly.
