How to replace the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1 on Chevrolet Astro?

Try raising the car before you start replacing Bank 2 Sensor 1 of the HO2S. Take off the connector from the HO2S before you continue. Take out the HO2S using the J 39194-B Oxygen Sensor Wrench. If you think it might help, put a small amount of GM 5613695 anti-seize compound on the new oxygen sensor threads; this product contains liquid graphite and glass beads to help take it off later. Use the Oxygen Sensor Wrench (J 39194-B) to fit in the HO2S and turn it until it reaches 42 N.m (31 lb ft). When it's done, attach the HO2S harness connector and then lower the vehicle.
