Installation steps:

Step1.Park your Vehicle, set the parking brakes and open the hood

Step2.Disconnect the negative battery terminal. Remove the plastic cover. Loosen the 10mm nut. Remove the negative clamp from the battery.

Step3.Locate the oxygen sensor on your Vehicle. Do not touch the sensor or the heat shield until the engine cools down.

Step4.Press the connector and pull it away to unplug the oxygen sensor. Use a flat head screwdriver to press the locking tab on the connector before you pull it.

Step5.Place the oxygen sensor socket on the sensor and break it loose. If the sensor cannot be loosened spray penetrating oil and let it sit for at least 10 minutes. This will make it easier to remove the old Vehicle oxygen sensor.

Step6.Install the new oxygen sensor. Tighten the new Vehicle oxygen sensor to the recommended torque. If you are not sure what the correct torque call your Chevy dealer.

Step7.Connect the oxygen sensor wire harness by plugging it in.
