Notice: Refer to Excessive Force and Oxygen Sensor Notice in the Preface section.
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 burns 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.
Notice: Refer to Component Fastener Tightening Notice in the Preface section.
Tighten
Tighten the HO2S to 42 N·m (31 lb ft).
