I want to help you save time and money repairing and 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 idler pulley for you serpentine belt on this '98 explorer. The procedure's the same for a lot of explorers with both the V6 and V8 engines. The tools you'll need are 8mm wrench, flat blade screwdriver, 3/8 drive ratchet handle, and a 15mm socket ratchet and handle. Disconnect the negative battery cable with an 8mm or 5/16 wrench. You're going to want to pull your intake hose back, which is fairly easy. You're going to loosen up this clamp here and then you want to unclamp your air filter box. Pull that off of your throttle body. Pull this up and you can flip this up and move it away. Now to remove the belt, right here is your belt tensioner and you want to take a 3/8 drive ratchet handle and it is square hole right in the tensioner. Put my wrench down in there and push down and you can the belt loosen up and slide it right off of the idler pulley and let your wrench back up, and you can take the belt off of all the components. Reach down and lift it off of the crank shaft and it comes up and off.

This right here is your idler pulley. Once you get your belt off you can actually test it, just try to shake it back and forth and spin it and you shouldn't hear any noise. If you hear noise or you feel play you'll want to replace it. This one actually is in good shape so we'll put it right back on. You got your 15mm socket on there, and a little trick for extra leverage, I put a larger wrench down around my ratchet handle and I pull nice and easy on the big wrench and that gives me the extra leverage and keeps my hands out of this area so they don't get cut up. Once it's loose, I can just use my ratchet. Then you do need to twist this little lock washer off. The bolt comes out and see there's little bushing right here. Here's a new pulley from 1AAuto, the original pulley. You can see they're both the same. We tested this one and it was still in good shape so I'll put that one back on. It's pretty easy. You put the bolt through and make sure this washer gets on the back, hold everything together, put it right back into place.

I'm going to use the same trick with my big wrench, tighten up and put the belt back on, very important. Here's your belt diagram. It shows how the belt is routed. What we want to do is make a little loop and work it around the crank shaft here first and then we'll work around everything else. Make that loop and make it tight and pass the belt under the shaft of the fan a little bit, get it into your other hand, get it up under the crank shaft and around the whole crank shaft and the top. Take the belt up and over the water pump, around the power steering pump and ac compressor, over the alternator and into the tensioner, press on it here. Make sure everything's lined up well. Push your tensioner down and in with your wrench then slide the belt underneath the idler and then you're all set. Put the air hose back over. Push it on the there, push it back in here. Then the three tabs right here, make sure they go into the right slots. Clip it back on. Make sure that's pushed on there well. Tighten your clamp back up. Make sure all these connections are still good. You're all set.

We hope this helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet, please feel free to call us toll free at 888-844-3393. We're the company that's here for you on the internet and in person.

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.

Okay, friends. To get started on replacing our idler pulley, we're gonna have to remove the serpentine belt. To do that, you're gonna have to relieve tension with the tensioner right down here. But before we go ahead and do that, just take a quick note of your serpentine belt routing. Meaning by that is how it goes around all of the pulleys. Once you have a quick note of that, just go ahead and use your 3/8 ratchet, we're gonna come right down into the groove, turn this counterclockwise, that's gonna release the tension, and we'll take the belt right off of the idler pulley.

At this point, we can continue on to removing our 13-millimeter headed bolt right here, and that'll remove the idler pulley. There's the idler pulley. Next, we need to remove this tab right here so we can get our mounting bolt out of there. Most times with these, what you can use is a pair of cutters. We're just gonna grab onto one of these ears, try to break this off. At this point, we can take the bolt with our washer off, and then remove the adapter as well. There's our idler pulley.

Now, we just wanna inspect this area here where the mounting plate is gonna be. We wanna make sure that it's nice and clean. After you're sure of that, go ahead and take your little adapter here, put it on the backside of the brand new pulley, start your bolt through. This looks great. Just like this. Now, let's get this onto the engine.

First, what we're gonna do, is we're just gonna go ahead and snug this up so it's bottomed out. Once we've done that, let's torque it to 37 foot-pounds. Now that that's torqued, let's get our belt back on there.

Now, if you set your belt inside the grooves, you're gonna see it fits perfectly. Essentially, just make sure it's not hanging off like this. If it does, it'll ruin the belt. Start this onto all my grooves. Make sure you're on all of the flat pulleys as well. This looks great. Okay. So, I have my belt on here now. Now, you just need to double-check. Like I said before, make sure it's sitting inside all the grooves. If it's hanging out, you're gonna ruin your belt.

Okay, friends. So, we successfully replaced our idler pulley. All you have to do now is start up the truck, let her run for 5 or 10 seconds, turn it off, come back out, and double-check to make sure your belt is on all those pulleys properly. Assuming it is, take it for a road test.

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 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.

If you were to look right down here, you're gonna see a clamp. If you were to look at the other end where connects onto the throttle body, you're gonna see another clamp. You can go ahead and loosen those up. Also, if you come right up here, you're gonna see an 8-millimeter bolt. If you loosen that up, you can take this right out. Once you have that out of the way and the clamps are loosened, you can wiggle this around. I'm gonna draw it off of the throttle body right here, and I'm gonna take them right there. Take it off of right here, remove it from the vehicle.

So now that we have the intake and the little shell out of the way here, it gives us a nice, clear view. You don't necessarily need to take off the shell, but I just like to have it out of the way. Go ahead and relieve your tension like that. And then I'm just gonna take the belt off of the idler pulley here and then I can let go of that. We'll get our serpentine belt tool right out of the way. Let's go ahead and remove the belt. To get started on your idler pulley, one of the best things you wanna do is to compare your new one to your old one. You wanna make sure that it's overall the same diameter, which would be the length right here from top to bottom, and you also wanna make sure that the depth is approximately the same. That's gonna be the area where the belt's gonna ride. This looks great, so let's get ready for an install.

Now we're gonna use a 15-millimeter socket, remove the mounting bolt. There it is. So now looking at the backside of it, you can see the area that's holding the mounting bolt in. It's like a little clippy do. It's a single time use and we're gonna break it off. Just going to hit it with some penetrant, let that sit for a second. Now I'm gonna grab some of these cutters and I'm gonna try to grab on to any of these ears I can, try to peen them up and rip this off. You can also use a pocket screwdriver, try to get under there. There we are. We can start separating everything. We'll pull this spacer right off of there. We're gonna reuse that. Grab this stuff, just like that.

Now we're gonna take our new pulley, our old adapter. This is the spacer that goes in between the pulley and the engine itself. We'll put that right along the backside. It should fit right in. That's great. Take it like this. Start the bolt through and now go ahead and start it right into the engine. Go ahead and torque it to 37 foot-pounds. Go ahead and take one side, go down and around the passenger side of the water pump, which is this right here, and then put it over the crank, which is the main pulley over there. I'm just gonna circle it, put it on, then slide it around.

I'm gonna take one and I'm gonna come up and over the tensioner right here. And then the other side, I'm gonna bring it down and around the water pump. And then underneath the power steering pump, it's gonna fit right inside the ribs perfectly. Then I'm gonna come up, make sure it's sitting in those ribs. There it is. Come up over the alternator right here. This looks good. Make sure everything's situated approximately where it needs to be. That looks great. I'm gonna grab my tensioner tool. Put it on there. Relieve tension.

Now we'll take this, bring it right in underneath the idler pulley. This is your idler pulley. Get our tool off, give it a nice tug. And then of course double-check all of your pulleys. Every one of them that has the rib side that goes up against the belt, you need to make sure it's sitting perfectly inside the ribs. If you're wondering what your belt routing should look like, you can find it right on the front. Get our air intake back on here. It's gonna go right underneath this hose here. Line it up there. Grab this, slide it in, push it all the way in so it's up against the whole throttle body. Make sure your clamps are nice and tight. Your hose over here should have a little clippy do. Ours is actually broken, but it's gonna push in right there and that'll hold it secure. This cover back on here, just slide it all the way back so it's sitting inside the pitons. Put this down and tighten up your bolt.
