How to replace the Heated Oxygen Sensor 2 on 2007 Buick LaCrosse?

The replacement process of heated Oxygen Sensor 2 starts with vehicle elevation and support. When disconnecting the heated Oxygen Sensor (HO2S) electrical connector exercise caution while twisting the connector to prevent damaging Exhaust Manifold/pipe threads. Moderate or low engine temperatures below 48°c (120°F) will cause the Oxygen Sensor to resist easy removal. Handle the ho2s by removing it with care to maintain the integrity of both the in-line electrical connector and the louvered end free from dirt and grease and other debris. For sensor reuse during installation add anti-seize compound to threads by using p/n 5613695 or an equivalent product. Position and snug the ho2s with torque between 2 to 42 n.m (31 lb ft), then connect its electrical connector before lowering the vehicle.
