Removal & Installation

  1. O2 sensor is mounted in exhaust pipe just below exhaust header. It is equipped with a permanent pigtail, which must be protected from damage when sensor is removed. Carefully disconnect engine harness from O2 sensor connector. DO NOT pull on oxygen sensor wiring when disconnecting sensor connector. Remove O2 sensor with Socket (C-4907). Sensor may be difficult to remove when engine temperature is less than 120°F (48°C).
  2. Ensure sensor is free of contaminants; avoid using cleaning solvents of any type. Clean the threads in exhaust manifold with an 18 mmx1.5 x 6E tap. If installing original sensor, the sensor threads must be coated with an anti-seize compound. New O2 sensors are packaged with compound already on threads. Tighten sensor to 20 ft. lbs. (27 N.m).
