5. Using the J 39194 , remove the position 2 HO2S.
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 already have the
compound applied to the threads. If the sensor is removed and is to be reinstalled, the threads must be coated with an anti-seize compound
before reinstallation.
1. If reinstalling the old HO2S, coat the threads with anti-seize compound GM P/N 12377953 or equivalent.
2. Using the J 39194 , install the position 2 HO2S.
Tighten the sensor to 42 N.m (31 lb ft).
3. Lower the vehicle.
