NOTE:
- New oxygen sensors are coated with assembly paste; the paste must not get into slots of oxygen sensor body.
- For a used oxygen sensor, only coat threads with hot bolt paste. This paste must not come into contact with sensor slots. Hot bolt paste.
- Electrical wire of oxygen sensor must always be secured in the same position when installing so that contact with the exhaust pipe is avoided.
- Tightening specification: 55 Nm
