5. Use the J 39194 in order to remove the HO2S.
INSTALLATION
IMPORTANT: A special anti-seize compound is used on the Heated Oxygen Sensor (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. When installing a previously removed sensor, the threads must have anti-seize compound applied
before the installation.
1. Coat the threads of the oxygen sensor with anti-seize compound GM P/N 5613695 or the equivalent if necessary.
2. NOTE: Refer to Component Tightening Note in Service Precautions.
Install the HO2S.
Tighten
Tighten the sensor to 42 N.m (31 lb ft).
