Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace an O2 Sensor on this 2006 Jeep Liberty with a 3.7 Liter V6 Engine, and both upstream and downstream O2 sensors are actually the same part and a similar process on this vehicle. We're just going to show you one of them. All you'll need for this are a new O2 sensor from 1AAuto.com, and a 7/8 inch O2 socket and ratchet or a 7/8 inch wrench.

Right here, is your bank 2 upstream O2 sensor, and here is your bank 2 downstream O2 sensor. On the other side, is your bank 1 upstream O2 sensor, and your bank 1 downstream O2 sensor, and this is the one we're going to show you the procedure on.

First, pull the harness free and then push on the tab on the connector and pull it free. For this particular O2 sensor you have a choice of which tool you can use. You can either use the O2 socket and a ratchet or you can use the 7/8 inch wrench. You really just loosen it with one of these tools and then you can remove it, the rest of the way by hand.

On the right, is the old O2 sensor. On the left, is the new one from 1 A Auto. You can see they're identical and will mount exactly the same. Twist your new O2 sensor into place and just tighten it up. Then re-clip your harness, and plug it back in. Now, you're all set.
