5. Raise and support the vehicle to an appropriate height to reach the HO2S. Refer to Vehicle Lifting.
6. Remove the HO2S from the exhaust manifold.
Installation Procedure
Important: 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.
Notice: Refer to Fastener Notice.
2. Install the HO2S to the exhaust manifold.
