- A special anti-seize compound is used on the oxygen sensor threads. The compound consists of a liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New sensors will have the compound applied to the threads.
- If a sensor is removed and is to be reinstalled, the threads must have an anti-seize compound applied before installation. Coat the threads of the HO2S with anti-seize compound, if necessary. Install the HO2S and tighten to specification. See TORQUE SPECIFICATIONS . Connect HO2S harness connector. Lower vehicle.
