Removing the oxygen sensor from the exhaust manifold may be difficult, if the sensor was overtightened during installation. Use tool C-4907 or equivalent, to remove the sensor. The threads in the exhaust manifold must be cleaned with an 18mm X 1.5mm X 6E tap. If the same sensor is to be reinstalled, the threads must be coated with an anti-seize compound such as Loctite® 771-64 or equivalent. New sensors are packaged with anti-seize compound on the threads and no additional compound is required. Sensors must be tightened to 20 ft. lbs. (27 Nm).
