How to remove and replace the oxygen sensor in a Buick Skylark,Oldsmobile Omega and Pontiac Phoenix?

In L4 engines, the oxygen sensor is a screw-in one located at the exhaust manifold and in V6 engines, it is on the exhaust pipe. For this reason, it is harder to unscrew the sensor when the engine is cold and it would be better if you did it while the engine is operating. In that case, jack up the front of the vehicle and rest it on jack stands to create enough room for your work. On L4 models, extract air cleaner. Oxygen sensor electrical connector should be removed by detaching its terminals. Apply a penetrating oil to the threads of the oxygen sensor during installation ensuring that it penetrates for approximately 5 minutes. Unscrew and remove carefully. Be careful not to damage threads in exhaust manifold/pipe while removing it. Before installing new sensor, coat its threads thoroughly with an anti-seize compound then install it properly. Torque carefully to 30 ft-lb (4.1 m-kg). Reconnect electrical connector to sensor itself as before mentioned. After replacing oxygen sensor reinstall air cleaner on L4 models and lower car on V6models to ground level.When replacing an oxygen sensor, always reset 'sensor' light on dash board panel.

Buick Skylark Oxygen Sensor

The Oxygen Sensor in Buick Skylark vehicles is expected for the control of air/fuel ratio and qualifies for the engine exhausts with a view of generating optimal performance while at the same time lowering emissions. Analyzing the difference in the oxygen content of the exhaust gases and the content of oxygen in the atmosphere, the sensor produces a voltage that controls the engine's frequency of fuel injection. For proper control and compensation, Skylark vehicles usually have at least two Oxygen sensors, before and after the catalytic converter. These sensors are effectively high-temp sensors and can erode over time from contamination which can elevate emissions and reduce gas mileage. In later models of vehicles, there is a sensor used which is known as the air/fuel ratio sensor unlike the oxygen sensor that only measures the air/fuel mixture.

Each OEM Buick Skylark Oxygen Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
