7. Using the J 39194 , remove the HO2S.
Installation Procedure
Important: A special anti-seize compound is used on the heated oxygen sensor 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 replacement 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 prior to installation.
1. If necessary, coat the threads of the HO2S with anti-seize compound Saturn P/N 21485279 or equivalent.
Notice: Refer to Fastener Notice.
2. Using the J 39194-C , install the HO2S.
Tighten the sensor to 42 N.m (31 lb ft).
