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.

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 idler pulley. This is a pulley that doesn't turn any accessories; it's just a pulley that holds the serpentine belt in its routing position. It's pretty easy. There are two tools you'll need. You'll need a 15mm socket with a ratchet handle and you'll also need a T50 Torx driver socket, with the same ratchet handle.

This truck has the 5-liter V8 engine in it. Obviously, your serpentine belt's right here. The first thing you want to do, though, is make sure that your belt diagram is intact. That's going to be a big help when you're putting the belt back on. It actually gives you a little diagram of how to do it. You'll need a 15mm socket on a ratchet. You take the socket and ratchet, put it right down here, on your tensioner bolt, and then you pull this counterclockwise. You can see that the belt loosens up when you do that. So, I pull the wrench that way, then you just slip it right off this idler pulley here. Then, slowly, let your wrench back, and take it off. Then just pull the belt off. Pull it right up. We have to reach down to pull it off the crank pulley, and the belt comes right up and out.

Once you have the belt off, then you can grab on the pulleys. You shouldn't feel any play, and they should rotate smoothly. This one actually has a lot of catching in it. We'll replace it for you. You'll need a T50 Torx driver. Just put that right into the bolt, make sure it's in there well. Once you get the bolt going, it comes off.

There's our original. The new one from 1A Auto is exactly the same. The original is- I'm sticking my finger in there and it's all bound up. This one, obviously works very nicely. It works well. I'll put the bolt in. Just put it right on. It's tight.

To put the belt back on, what you're going to do is take a loop and feed it down, and get it on this crankshaft pulley first, and then hen up around this air pump. Then you're going to flop it over, down here to this power steering pump, up to the A/C, then across. We'll put it on the alternator, and keep it off the idler pulley first. Here's a new belt from 1A Auto. We'll put it down. We'll reach down on the other side of the motor, and pull a loop down onto the crankshaft pulley. Pull some of the slack out. Then take a loop and go down to the power steering pulley way over here on the other side. Bring it up onto the A/C pulley. It goes down around and it comes up from the crankshaft pulley to the air pulley, and then it goes around the tensioner, then around the alternator. This belt is a little bit tighter. What we're going to do is put it around the alternator first. What I'm going to do is just put the socket, I've got the belt around the socket here. Take some tension off with this wrench. First, I'll get it right on the tensioner pulley. Now it's actually on the tensioner pulley. It's on everything correctly. It's on the A/C, it's on the power steering, here on the water pump, way down underneath the crank, and everything. Now, I can pull the tensioner back. Take it and push it underneath this idler pulley. Let the tensioner off. It's all set.

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.

In this video, we're working on this 2001 Chevy Malibu, and this repair is basically the same for any '97-'03 Malibu with the 3.1 liter. We're going to be looking at the serpentine belt idler pulleys, checking them, seeing if they're okay, and then if need be, replacing them. Tools you'll need are a jack or engine hoist, 15mm and 18mm sockets with ratchet and extension. You need a 3/8 inch drive, and you either need a flexible bar or the ratchet handle.

Your serpentine belt is obviously right here on the passenger side of your engine. What you actually need to do is remove this engine mount, which involves removing two 18mm bolts here and two 15 mm nuts, one there and one down there. That is the engine mount, so you either need to support here with an engine crane, or you need to use a jack and support underneath the oil pan here. Do not jack the car up yet. You actually just want to support the weight of the engine. Spray some penetrating oil on those studs down lower, and I've cheated a little bit, with a 15mm socket and an impact wrench. No reason you can't reach everything pretty easily with just a regular ratchet and extension. I've got my 18mm socket on here. I'll loosen up one of these bolts. I'm going to start loosening the other bolt, and you're going to see the engine falling, which is actually more the car rising. What you want to do now is take your jack, and jack the engine up. Now it's supporting the engine. You can remove these bolts the rest of the way. For this mount, slide it back and right out. I'm just going to remove these two lines, just to make it easier for you to see.

Now, what you want to do is take your jack, and jack the engine up a little bit extra. Now right down in here is your tensioner. What I have is a little flex arm. What you want to do with this flex arm is put it down; there is a 3/8th hole at the bottom of the tensioner. You want to put it in, just like that. Here is my bar. I'm going to reach in, and I'm going to pull the bar up, which pulls on the tensioner. It releases the tension on the belt, and you can pull the belt off and then slowly release your bar back down. Be careful not to pinch your fingers. Take the bar out, and then just take your belt off of all the pulleys.

There are two idler pulleys on here: one here and then one right down here. To test those, spin them, listen for any noise, try and shake them back and forth to see if there is any play in them at all. If you do want to change the idler pulley, remove a 15mm bolt and the pulley comes off. I see the idler's in okay shape so I'm going to put it back on, and the same goes for the one down there.

Here is your belt routing diagram. This is key. Make sure you have this before you take the belt off. If you don't have this, make sure you draw yourself a diagram similar, so you can get the belt on again. It's kind of hard to film this, so you're just you're just kind of have to take my word that I'm doing what I'm saying I'm doing. Take your belt, and you want to put a loop down underneath the crankshaft, which is the lowest, largest pulley and then the A/C compressor, which is the pulley that's lowest and closest to the front of the vehicle. It comes up, under this power steering pulley, and right up over here. Now, I'm going to reach down and I'm pulling it back to this idler pulley here, and then around under the tensioner pulley, and then I can pull it up on top of my alternator right here. Now, I'm all routed except for this idler pulley. Now, I'm going to take my 3/8th bar and get down in to my tensioner. Use both hands. Pull the bar up, grab on to my belt here and slip it under the idler pulley and let my tensioner go. I'm off a little bit here. Now check to make sure your belts on correctly everywhere. It's not quite on my crank pulley correctly. Pull up again on the tensioner, reach down and kind of flip it a little bit. Now it's on there correctly. It appears to be on everywhere correctly.

We're just going to kind of speed through putting this stuff back in. Put the mount back down in there, and then you can let your engine down just a little bit. Start the two top bolts on the mount and kind of preliminarily tighten them up. Then, you can let the engine all the way down. Take the jack out. Then start your 15mm nuts on top and preliminarily tighten them as well. Here I'm just reconnecting those hoses that I moved out of your way. Use a wrench. Make sure the mount bolts are tight, but not too tight.
