Installation Procedure
Important: A special anti-seize compound is used on 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 components and if for any reason the sensor is to be reinstalled, the
threads must have anti-seize compound applied before the reinstallation
