J 39194-C Oxygen Sensor Wrench
Notice: The HO2S uses a permanently attached pigtail and connector. This pigtail should not be removed from the HO2S. Damage or removal of the pigtail or connector could affect proper operation of the sensor.
Important: Removal of the sensor is easier if the exhaust system is slightly warmed up. Be careful that the exhaust is not hot to work on safely. Moving the sensor back and forth while applying penetrating oil to the threads will aid in the removal and will decrease the chance of exhaust pipe thread damage.
Notice: Silicone based products will contaminate the HO2S. Use only a nickel based anti-seize compound that does not contain silicone.
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the oxygen sensor-to-exhaust manifold to 45 N·m (33 lb ft).
Important: DO NOT apply any material in the HO2S-1 harness connector such as grease or dielectric compound.
