How to Service the Heated Oxygen Sensor on Mercury Milan?

The first step for servicing the Heated Oxygen Sensor (HO2S) requires disconnecting the electric connector. Apply penetrating and lock lubricant to the sensor threads and use it as a helping agent during extraction. The Exhaust Gas Oxygen Sensor Socket is needed to extract the HO2S. Correctly set the torque wrench to the specified torque value then tightly fasten the sensor to 48 Nm (35 lb-ft). The HO2S threads should get a thin layer of anti-seize lubricant before the reverse installation process takes place.
