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 serpentine belt tensioner on this 2003 Chevy Monte Carlo. It's the same part and similar process on these Monte Carlos from 1995 to 2005. And the items you'll need include a new serpentine belt tensioner from 1AAuto.com, a 3/8 inch ratchet, and a 10mm, 13mm, and 15mm socket and ratchet.

Your serpentine belt tensioner is located right here, but before we can remove that, we have to remove a couple other things. So remove these two, and these two 13mm nuts, and once those are removed you can lift that brace bar up and off. Then remove these two 10mm nuts. Lift the bottle up and out, and set that aside.

And now, using a 3/8 inch ratchet, just push it into the square and hold on the tensioner. Then pull back, and then pull the belt off the alternator. And that will loosen it up off the tensioner as well. Then release the tension on the tensioner and pull your ratchet free. Now, to remove the tensioner, you want to remove this 15mm bolt, and we'll fast-forward as Mike does that. And pull your tensioner up and out.

Take your new tensioner and line up that tab with this hole here. Take your bolt, push it through the tensioner, and feed the tensioner down in place. Make sure that tab goes into the hole, and that it's all lined up. And we'll just fast-forward as Mike tightens up that 15mm bolt.

Now, using your 3/8 inch ratchet, again, put it into the tensioner and pull up on it. And then just put your belt back on the alternator pulley, and then release the tension on the tensioner and pull the ratchet free. Now line up this slot onto this tab right down here, and just feed the bottle down into place. And make sure those top holes go down onto those studs, and then replace those two 10mm nuts. Take your brace bar and put it back down onto these studs up here. And then replace those four 13mm nuts, and tighten them up.
