Here are the items you'll need for this repair: 13mm socket, ratchet, socket extension, torque wrench

Be sure your vehicle has a belt path diagram somewhere on the cowl or under the hood before removing the belt. If it's missing or unclear, be sure to draw it somewhere under the hood or take a good picture. Put the 3/8 drive of a ratchet into the square on your serpentine belt tensioner and turn it counterclockwise to release tension. Then simply pull the belt off of any one of the pulleys, slowly release the tension from the tensioner. Remove your ratchet, and take the belt off of the pulleys.

Your idler pulley is located at the top center of the engine at the front, right between your alternator and your A/C if your vehicle came equipped. Use a 13mm socket and ratchet to remove the 13mm bolt in the center of the pulley. Remove the pulley from the vehicle.

Now our pulley is still in okay shape, so rather than waste a new part, we're going to reinstall it, but installing your new part will be exactly the same. Simply line up the bolt, which is captured inside of the pulley so it doesn't come out. We'll bring that in as far as we can by hand and then tighten it down with our 13mm socket and ratchet before torqueing. Torque this bolt to 37 foot pounds. Make sure that it rolls smoothly and freely.

Hook the serpentine belt around the crank pulley or harmonic balancer from the passenger side. Be sure that it seats fully into the grooves of the pulley and doesn't lay over the edge on either side. Wrap the driver's side of the belt around the water pump, under the power steering pump on the other side, and up and over the AC compressor. I already have the left side wrapped around the tensioner here just because that's where it falls. Then, from over the AC compressor under the idler pulley, reinstall the ratchet into the tensioner. Turn the ratchet counterclockwise to release the tension, and install your belt over the alternator. Take a second just to look around and make sure that your belt is seated and routed properly before releasing the tension and removing your ratchet.

Hi, I'm Don 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 idler pulley on this 2002 Chevy Suburban. It's the same part and process on these Suburbans from 2000 to 2008. The items you'll need for this are a new idler puller from 1Aauto.com, a 10 and 15 mm socket and ratchet, and a flat blade screw driver.

Start off by loosening these two hose clamps, using your flat blade screw driver. We'll just fast forward as Don does this. Just pry this clip out and then pull the hose back. You may need a flat blade screwdriver to help you pry it free. Then pull forward and lift it up and out.

Next, remove these two 10mm bolts, and we'll fast forward as Don does that. Pry the clip on this hose out of the fan shroud. Then remove these four clips around your shroud. To remove these clips, you just pry up the center and then pull the clip out. We'll fast forward as Don does this to the other three. Now, just pull that hose back and lift the shroud straight up and out.

Using a 15 mm socket and ratchet, just put it here on the tensioner. Push down on the tensioner and pull the belt up and over the idler puller. Then, carefully release then tension on the tensioner and loosen this 15 millimeter bolt. We'll just fast forward as Don loosens that. Once you loosen that enough it will just pull free with the pulley. Now, to separate the bolt from the pulley, you just need to pry off this ring and then pull the bolt out.

On the left is the old idler puller. On the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Put the bolt back into the idler pulley and then slide that nut down, and then that ring. Make sure that ring's pushed all the way back down in and that you bend those tabs back down if they got popped up when you pried it off. Then, push the pulley back into place with the bolt and just start hand tightening it. Once you've got it started you can use your ratchet to tighten it up the rest of the way. Now, push back down on the tensioner and push the belt back underneath the idler pulley. Then carefully release the tension on the tensioner and pull the ratchet free.

Now, to replace the shroud just push it back down into place. Then replace those four clips. Just push them back down into place and push the center down to lock them. Push the hose back into place and then replace those two 10 mm bolts.

Now, take this air intake hose and push it back down into place on the air intake box, and then, on to the engine. Then just tighten up those two hose clamps. Then just re-clip that hose to the air intake hose, and you're all set.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the idler pulley on this 1996 Chevy Tahoe with the 5.7-liter V8 engine. It's the same part in similar process on a large variety of GM vehicles, and it fits the Tahoes from 1996 to 2008. The items you'll need for this include: a new idler pulley from 1AAuto.com; a 10mm and 13mm socket and a ratchet with an extension; and a 3/8-inch ratchet.

First, we need to just remove this cable. Push back on that tab and pull the harness up and out. Next, you want to remove this series of 10mm bolts that line this panel. We'll just fast-forward as Don removes each of those. Now, lift that shroud up and off.

Now, using your 3/8-inch ratchet, just push it in to that square hole. Then when you push down on it, it will loosen up the tension on the belt allowing you to pull it free. Just start off by pulling off the alternator, and then carefully let the ratchet up, pull it out, remove your belt the rest of the way, and pull it over that fan. Your idler pulley is located right here, and it's held in with a 13mm bolt. Just go ahead and remove that. Once that's removed, the pulley will pull right off.

Take your new idler pulley and push it into place with the bolt already through it, and just tighten that bolt up. Now, to put the serpentine belt back on, you're going to want to use this belt routing diagram. If you don't have AC, you use the dash line. If you do, then you're going to use the solid line, and you just want to follow this and put your belt on in this order. It's kind of hard to show Don doing it, so we're just going to fast-forward as he fits it over each of the pulleys.

When all that's left is your alternator, put that 3/8-inch ratchet back into your tensioner, push down, put the belt up on the alternator, and then carefully release the ratchet and pull it out. Fit that shroud back down into place, and make sure all of your holes are lining up. We'll just fast-forward as Don replaces that series of 10mm bolts. Now, just push that harness back into that clip and push it down into place.
