Oxygen (O2) Sensor: Installation
- Whenever an oxygen sensor is removed, its threads must be coated with anti-seize compound before it is reinstalled. New oxygen sensors will already have this compound applied to threads.
- Install oxygen sensor in exhaust pipe and tighten sensor to 30 ft. lbs. (41 N.m).CAUTION: Correct torque of O2 sensor is critical to prevent crushing glass beads in graphite anti-seize compound. Crushing glass beads will cause sensor to seize in exhaust manifold, causing necessary replacement of exhaust manifold upon next removal attempt.
- Reconnect electrical connector to oxygen sensor. Lower vehicle from hoist. Reconnect negative battery cable.
