3. Raise and support the vehicle. Refer to Vehicle Lifting.
4. Remove the HO2S (4) from the exhaust pipe.
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.
2. NOTE: Refer to Fastener Notice.
Install the HO2S (4) to the exhaust pipe.
Tighten the sensor to 42 N.m (31 lb ft).
