2000 Buick Century Parts Questions & Experts Answers

• Q: What tools and steps are required to service and repair the heated oxygen sensor (HO2S 1) on 2000 Buick Century?

  A: The necessary tool for heated Oxygen Sensor (HO2S 1) repair or servicing is heated Oxygen Sensor socket (J 39194-B). Initially detach the electrical connector. Caring use of the heated Oxygen Sensor socket (J 39194-B) is needed to remove the sensor because temperatures below 48°c (120°F) make it difficult to break loose and prevent damage to Exhaust Manifold or Exhaust Pipe threads. Check all power sources off before starting the installation process and remove the electrical connection. The threads of the heated Oxygen Sensor require special anti-seize compound made of graphite suspension in fluid with glass beads just like new or service sensors. Prior to reinstalling the sensor on serviceable components also apply the anti-seize compound p/n 5613695 or its identical alternative to the threads. Tighten the installed heated Oxygen Sensor to 42 ± n.m (31 lb ft) for the ho2s 1 that exists before the catalytic converter. Finally, reconnect the electrical connector.
