Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly: that's going to save you time and money. Thank you and enjoy the video.
In this video, we're going to show you how to replace the serpentine belt tensioner on this 1998 Volkswagen Beetle. This vehicle has the 2.0 liter. The only tools you'll need are a pair of locking vice grip pliers and a 13mm socket and ratchet or a wrench.
First, start by pulling your oil dipstick out and pull up on this cover and remove it. Put the dipstick back in so nothing gets in there. Now, looking down here, here's your tensioner, right here. I'm just going to pull this hose up out of the way. Here is your tensioner, your belt goes right around here, and the alternator right here. What you can do is reach right under and if you can pull on your belt and you can see the tensioner move at all, you know that it's weak and It needs to be replaced. To remove the belt, you take a socket. It goes right onto this knob right here with an extension and then just pull it like that and then just reach right around your alternator and pull the belt off your alternator. Then, you can carefully let your tensioner back up.
There you saw me do it with a socket and extension, now you can also use a pair of vice grip locking pliers and lock on to that square that's on top of the tensioner and release the tension from the tensioner that way.
You can just leave the loop right down like that. Your tensioner is held on by three bolts here. Use a 13mm socket with a small extension and a ratchet. You could use a wrench as well. I'm just going to fast forward as I remove those three bolts. Like I said, use a 13 mm socket with a ratchet and extension. You could also use a 13mm wrench. These bolts should not be too tight. Once you take the bolts out, you're going to slide down under that bracket, up and out.
The new tensioner from 1A Auto is just like the old one. Put it down and underneath and bring it back up and let's start the bolt that goes to that bracket first. We'll speed up here again. For those bolts just put them in by hand first, thread them in most of the way and then tighten them up with your wrench. You want to tighten them probably about 25 to 30 foot-pounds. Here's a belt diagram and really all you need to do to take the tensioner off is to just take it off the alternator on top but if you did happen to take it off all the way, this will help you get it back together correctly. The nub on the new one is slightly smaller so I just went to a pair of vice grip pliers, push them down, pull out your pin and slowly let the tensioner do its work. Remove your oil dip stick and put your cover back on. It slides into a little cushion in the back and then two in the front. Once you've got that you put your oil dip stick back in and you're all set.

I hope this how to video helps you out and next time you need parts for your vehicle, think of 1AAuto.com. In this video, we'll show you how to replace a serpentine belt tensioner on this 2003 Volkswagen Passat and this vehicle has the 1.8 liter T motor, it has a turbo motor. The only tools you'll need are a 17 millimeter wrench and a 13 millimeter wrench. In this video we just showed you replacing the tensioner itself.
If you wanted to replace the belt at the same time which is usually a good thing to do, you can check out our other videos and you'll see a video for replacing the serpentine belt on this vehicle as well. The tensioner for your alternator belt is right up here, 17 millimeter wrench, put it on there and pull on the tensioner and flip the belt off and let the tensioner back. There are three 13 millimeter bolts here. My 13 millimeter wrench on there. Here's my 17 millimeter giving me a little extra leverage. We'll just loosen that off. I'm just going to speed it up as I loosen the third one up. Then, these bolts actually pretty easily come up by hand and so that's basically what I'm doing here is once I have them loosen up just backing them out by hand. This one goes off and tensioner comes up right up and out.
New tensioner from 1A Auto. This is a great one. What I'm going to do is put these bolts into place. This makes it a little easier to get it down on there. Put the tensioner down into place here. That top bolt going in. I have two bolts going in and hand thread it in. Once again, I'll turn on the speed here as I thread those bolts in and then pull them narrowly, tighten them up with the wrench. I'm going to tighten them up. Just use your wrench. It should probably be about three, three to five pounds but we're going to tighten it with this wrench. This will do the trick. The new tensioner does come with a little stop in it so we'll put our 17 millimeter wrench on there, pull on a little bit and pull that stopper on right out. Then, slowly let back. Now, you can see that belt sticking right up through there. I'm going to grab onto my tensioner, that 17 millimeter. Pull it loose. Pull the belt right up onto the alternator, let the tensioner loose so I can see it now. My bolt actually came off of that power. Reach down there. Is that on there? Let it tight up. Just look down in see down, cranked correctly. The power straightened up correctly. It's maybe a little off here. Push it on the points a little bit more and it's all set.

The part fit and functions perfectly. 4 stars due to the poor packaging. The part almost punctured the box because there was only the packets of air that had popped during transit.
