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 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.
