Removal & Installation

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. Ensure sensor is free of contaminants. Avoid using cleaning solvents of any type. Sensor may be difficult to remove when engine temperature is less than 120°F (48°C). Always use anti-seize compound on threads before installation. Tighten O2 sensor(s) to 33 ft. lbs. (45 N.m).
