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 tensioner on this 2005 Volkswagen Jetta. The items you'll need for this is a 15 and 17 millimeter socket and ratchet, T25 Torx bit, an M10 12-point bit, flat blade screwdriver, torque wrench, and jack and jack stands.
Using your pick, 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 just inserts into that special lug nut and then removes the same as the other lug nuts, using a 17 millimeter socket. If you have air powered tools, you can raise your vehicle then remove the lug nuts. If you don't, loosen the lug nuts while the vehicle is on the ground, then raise and support the vehicle and remove them the rest of the way. 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.
Using a 15 millimeter socket and ratchet, just put it on the tensioner and pull back. Pull the belt up this front pulley. Release the tensioner and pull the belt off this pulley. Remove the 15 millimeter bolt on the tensioner. Now, you can remove that pulley.
Then, using your M10 12-point bit and the appropriate socket size, in this case, I think we used a 13, you just want to loosen up and remove that bolt. Now, your tensioner will pull free.
There's a wider tab and smaller tab. The wider tab goes up here, smaller tab down here. We'll fast-forward as Mike replaces that M10 bolt and tightens it up.
Then, replace the pulley and the bolt that holds the pulley in place, and just tighten that up. Put your ratchet back on the tensioner, tuck the belt onto that larger pulley, and pull the tensioner back, and put it onto the front pulley. Release the tensioner. Then, just replace that panel and all 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.
