1. Turn OFF the ignition.
2. Raise the vehicle. Refer to Vehicle Lifting.
3. Disconnect the sensor electrical connector.
4. Use the J 39194-B in order to carefully back out the heated oxygen sensor.
Installation Procedure
IMPORTANT: A special anti-seize compound is used on the heated oxygen sensor threads. The compound consists of graphite suspended in fluid
and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already
have the compound applied to the threads. If a sensor is removed from an engine and if for any reason is to be reinstalled, the threads must have
anti-seize compound applied before reinstallation.
1. Coat the threads of heated oxygen sensor/catalyst monitor with anti-seize compound GM P/N 5613695, or equivalent if necessary.
NOTE: Refer to Fastener Notice in Service Precautions.
2. Install the heated oxygen sensor.
Tighten
Tighten the HO2S 1 (pre-catalytic converter) to 41 N.m (30 lb ft).
3. Connect the sensor electrical connector.
4. Lower the vehicle. Refer to Vehicle Lifting.
