Removal & Installation

To locate oxygen sensor, see Figure-23. Oxygen sensors are 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 sensor to specification. See TORQUE SPECIFICATIONS .
