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 replace the upper oxygen sensor in this 2005 Hyundai Elantra with a 2.0 liter. Tools you'll need: you'll need a 12 millimeter socket and ratchet and probably a piece of pipe for some extra leverage. You'll also need a special 02 sensor socket with a corresponding ratchet.
I've located the coil next to the air box on the left hand side, driver side of the engine. I'm going to access it by removing four 10 millimeter bolts that hold the engine cover in place.
I'm going to speed up here. What you saw Donny do there before was, he used a piece of pipe on his ratchet to give him some extra leverage. These bolts that hold the heat shield on can be hard to break free. As you see, they do come out. There are those who would say that you don't have to remove your heat shield, and that may be true, but you do run the risk. If you don't remove your heat shield, you run the risk of possibly putting a slice in the 02 sensor wire when you reinstall it. We prefer to just take the extra step and remove the heat shield. I'm sliding the harness out of the clip on the heat shield. I'm going to take a flat blade screw driver and put it into the connector. See, on the top is a clip. Just give a little twist. You'll hear it click, and you can pull out the connector. Pull the heat shield, up and off.
I get my 7/8 inch socket and it's especially designed for oxygen sensors. You can see the cut out. It will slip right over the wire. I'm going to use a socket wrench and pipe. Once it's broken free, just twist. If it doesn't, just continue to work it around.
I've got my new part from 1A Auto, exact replacement. I'll put the heat shield back on threading the parts through. We'll speed up here, as we install the four bolts that hold the heat shield and then tighten them up. Plug in the new sensor back in, making sure you hear it click, then routing the harness through the clip. The final step is to put the engine cover back on.
