glass beads. The graphite burns away, but the glass beads remain, making the sensor easier to remove. New or service sensors already have the
compound applied to the threads. If you remove an oxygen sensor and if for any reason you must reinstall the same oxygen sensor, apply the anti-seize
compound to the threads before reinstallation.

1. Coat the threads of the heated oxygen sensor with the anti-seize compound P/N 5613695, or the equivalent if necessary.
2. Install the heated oxygen sensor. Tighten the HO2S to 41 Nm (30 lb. ft.).
3. Connect the HO2S electrical connector.
4. Lower the vehicle.
