Enclave AWD V6-3.6L (2009)
Note: A special anti-seize compound is used in the HO2S threads. The compound consists of liquid graphite and glass beads. The graphite tends to burn
away, but the glass beads remain, making the sensor easier to remove. New, or service replacement sensors already have the compound applied to the
threads. If the sensor is removed from an exhaust component and if for any reason the sensor is to reinstalled, the threads must have anti-seize compound
applied before the reinstallation.
1. If reinstalling the old sensor, coat the threads with anti-seize compound GM P/N 12377953, or equivalent.
Caution: Refer to Fastener Caution (See: Service Precautions/Vehicle Damage Warnings/Fastener Caution).
2. Install the HO2S (3) to the exhaust pipe.
Tighten the sensor to 42 Nm (31 lb ft).
3. Connect the HO2S electrical connector (6) to the engine wiring harness electrical connector (5).
4. Install the CPA retainer (4).
5. Lower the vehicle.
