Hi, I'm Mike 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 the AC belt on this 2005 Volkswagen Jetta. The items you'll need for this is a 15mm and 17mm socket and ratchet, a T25 Torx bit, a flat blade screwdriver, a torque wrench, and jack and jack stands.

Use your pick to remove these caps. For one of these lug nuts, you're going to have to use a key. The key can be found in your trunk with the spare tire. It inserts into that special lug nut, and then removes the same as the other lug nut using a 17mm socket. If you have air powered tools, you can raise your vehicle and then remove the lugs nuts. If you don't, loosen the lug nuts while the vehicles on the ground. Then raise and support the vehicle and remove them the rest of the way. Then your wheel will pull free.

Next, you want to remove this panel. It's held in with a series of T25 screws. There's also a few of them down here. We'll fast-forward as Mike removes those. Now you can pull this panel down. Pull down the front first and then it slides out.

Now, using a 15mm socket and ratchet, put it on the tensioner and pull back and pull the belt off this front pulley. Release the tensioner and pull the belt off this pulley.

Take your new belt and put your ratchet back on the tensioner. Tuck the belt onto that larger pulley, then pull the tensioner back, and put it on to the front pulley. Release the tensioner. Then replace that panel and all of the screws and tighten them up.

Replace your wheel, and you'll realize here that lug nuts are a bit easier than lug bolts. You have to try to hold the wheel in place while you put a lug bolt through. You want to balance it on the hub, and eventually the bolt will line up and push in. Then you want to tighten those preliminarily, and replace and tighten up each of those. Then lower the vehicle and tighten them up the rest of the way. Torque each of these to 100 foot-pounds in a crossing pattern, and replace your lug nut caps.
