    NOTE:

    A special anti-seize compound is used in 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 component and if for any reason the sensor is to be reinstalled, the threads must have anti-seize compound applied before reinstallation. Adhesives, Fluids, Lubricants, and Sealers

    Using a suitable tool, install and tighten the heated oxygen sensor (1). Fastener Specifications
