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.
