• Q: How to replace the Heated Oxygen Sensor (HO2S) using the J 39194 Oxygen Sensor Wrench on 2001 Buick Regal?

  A: When replacing the heated Oxygen Sensor (HO2S) the j 39194 Oxygen Sensor wrench (J 39194) serves as the tool for both removal steps and installation. Start by taking the fuel injection sight shield off and turning off the ignition before proceeding. Disengage the ho2s retaining clip from its bracket position before removing the ho2s electrical connector tab from this retaining clip followed by the electrical connector retainer. Safety protocols require vehicle elevation and engine temperature maintenance at 48°c (120°F) for uncomplicated sensor removal procedures. The j 39194 tool helps extract the rear Oxygen Sensor from the rear Exhaust Manifold. The threads of the new or reused sensor require an application of anti-seize compound p/n 5613695 or equivalent material if no compound exists already. To install the rear Oxygen Sensor you should place it into the rear Exhaust Manifold and torque it to 41 n.m (30 lb ft). The last steps involve lower vehicle operations followed by ho2s electrical connector reconnection and electrical connector tab bracket attachment and electrical connector retainer installation and fuel injection sight shield replacement.
