Downstream Heated Oxygen Sensor: Installation
WARNING: This page is about a different car, the 2003 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
- 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 bank 1 sensor 2 with anti-seize compound, if necessary. Install the bank 1 sensor 2 and tighten to specification. See TORQUE SPECIFICATIONS . Connect bank 1 sensor 2 harness connector. Lower vehicle.
