4. Remove the HO2S electrical connector clip from the junction block bracket.
5. Using the J39194, remove the HO2S (1).
Installation Procedure
Important: A special anti-seize compound is used on the HO2S threads. The compound consists of a liquid graphite 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 have the compound
applied to the threads. If a sensor is removed and is to be reinstalled, the threads must have an anti-seize compound applied before installation.
1. If reinstalling the old HO2S, coat the threads with anti-seize compound GM P/N 12377953 or equivalent.
Notice: Refer to Fastener Notice.
2. Using the J39194, install the HO2S (1).
Tighten the HO2S to 41 N.m (30 lb ft).
