G6 V6-3.9L VIN 1 (2006)
INSTALLATION PROCEDURE
1. Coat the threads of the HO2S with anti-seize compound GM P/N 12377953 or equivalent, if necessary.
NOTE: Refer to Heated Oxygen Sensor (HO2S) Resistance Learn Reset Notice.
IMPORTANT: A special anti-seize compound is used on the HO2S 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 is to be reinstalled, the threads must have anti-seize compound applied
before reinstallation.
2. Install the HO2S (1).
NOTE: Refer to Fastener Notice.
Tighten the sensor to 42 N.m (30 lb ft) using the J 39194-B.
3. Connect the HO2S electrical connector (1).
4. Install the CPA retainer (2).
5. Ensure that the HO2S connector clip (3) is attached to the stud on the engine.
