2002 Buick Regal Parts Questions & Experts Answers

  • Q: How to replace the Heated Oxygen Sensor (HO2S) using the J 39194 Oxygen Sensor Wrench on 2002 Buick Regal?
    A: When replacing the heated Oxygen Sensor (HO2S) you must use j 39194 Oxygen Sensor wrench (J 39194) to perform both installation and removal steps. First lift the vehicle while maintaining support under it. Begin by pulling out the retaining tab from the electrical harness connector then the connector itself will unlock. The temperature for this procedure should exceed 48°c (120°F) because lower temperatures make the sensor removal harder and could damage the Exhaust Manifold or pipe threads. When uninstalling the sensor from the Exhaust Pipe with tool j 39194 apply special anti-seize compound to reused sensor threads by using p/n 12377953 or its equivalent. After inserting the Oxygen Sensor into the Exhaust Pipe use the j 39194 torque wrench to apply 41 n.m (30 lb ft) force when tightening the sensor. Secure the ho2s electrical connector with its retaining tab while finished by lowering the vehicle.
