J 39194-C Oxygen Sensor Wrench
Notice: The oxygen sensor uses a permanently attached pigtail and connector. Do not remove the pigtail from the oxygen sensor. Damage to or removal of the pigtail connector could affect proper operation of the oxygen sensor.
Notice: The use of excessive force may damage the threads in the exhaust manifold/pipe.
Important:
• The in-line connector and louvered end must be kept clear of grease, dirt or other contaminants. Avoid using cleaning solvents of any type. DO NOT drop or roughly handle the heated oxygen sensor (HO2S). • The HO2S may be difficult to remove when the engine temperature is less than 48°C (120°F).
Important: A special anti-seize compound is used on the heated oxygen sensor threads. The compound consists of a liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service replacement sensors will have the compound applied to the threads. If a sensor is removed and is to be reinstalled, the threads must have an anti-seize compound applied prior to installation.
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the sensor to 42 N·m (31 lb ft).
Important: Use care when securing the HO2S electrical lead into the trough on the exhaust heat shield, as not to pinch the lead.
