Now, this vehicle is missing the belt path diagram. Normally it would be under the hood or up here on the cowl somewhere, so I'm going to go ahead and draw my own on it. We'll start up top with the AC pulley. The belt then goes down the to bottom, to our alternator. We have our fan pulley right in the middle and to the inside of them. All the way down at the bottom, we have our crank pulley, which we'll make larger than the rest. We then have our water pump pulley, our power steering pump pulley up here at the top right, and down below our power steering pump and close to the water pump, we have our tensioner pulley.

Now, we'll draw the belt, which goes over our A/C, under our alternator, up over the fan pulley here, and down and around the crank pulley. The crank pulley comes up, and goes over the tensioner, under the power steering, around the power steering – I've drawn this a little tight here – under the water pump, and back up over to our A/C pulley. Now, we have a good path of where it goes. We can be confident, removing our belt, that we'll make sure it goes back in the exact same path.

Using a 15-millimeter wrench, we'll loosen the bolt at the center of our tensioner pulley. Do not remove this fully. Just loosen it up enough that when we adjust the tension, the pulley will move freely. It should only take a couple of turns. If your vehicle's been run recently, be careful, because this housing up here is very hot. Using a 15-millimeter socket, ratchet, and extension, we'll loosen this tensioner bolt here until we can remove our belt. You can see as we loosen it, it moves our pulley down, taking pressure off of our serpentine belt. Once the tension's off, it's easiest to remove the belt from a smooth pulley, like our water pump pulley here. We'll slide the belt off of it.

Install your belt starting around the crank pulley at the bottom. The right side goes over the fan pulley. The belt goes over the fan pulley, under the alternator, over the A/C compressor, under the water pump pulley, over the power steering pulley, and over the belt tensioner as well. It may be easier to go over the belt tensioner and around the power steering pump before going under the water pump pulley in the same way that we removed it.

With a new belt, you may have to loosen up the tensioner some more. Tighten the tensioner bolt with your 15-millimeter socket, ratchet, and extension. Feel the belt to make sure that it's on there snug, with a little bit of flex. If you have it on there too tight, it'll break, too loose, and it won't turn the pulleys properly. You may have to make an adjustment after you get the vehicle running again. Before running the engine, after you've tightened down the tensioner, make sure you tighten down that center 15-millimeter bolt on the tensioner pulley.

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 on this 2005 GMC Savanna 2500. It has the 6 liter V8 engine in it. The only tools you're going to need for this is a 10 millimeter and a 15 millimeter socket and ratchet and a flat blade screwdriver.

The first thing that you want to do is remove these two 10 millimeter bolts that hold in your air intake box. Now disconnect the harness to the air intake box. Set it aside. Then, you want to use a flat blade screwdriver to just loosen up this clamp. With the clamp loosened up, you should be able to just lift and pull out your air intake box. Now, using a flat blade screwdriver, loosen up the clamp on this part of the air intake. Once that's loosened up, you should be able to just pull that up and out.

Now, you want to remove your radiator overflow bottle. Just remove the 10 millimeter bolt that holds it in place. Then it will just lift up and pull out and you just want to set that aside. Now that you can see the serpentine belt, you want to use a 15 millimeter socket and ratchet and place it on the tensioner pulley. You just want to push that down and it will loosen up the belt and you'll be able to pull it off the alternator and then pull it off all the other pulleys. Just pull it up and out.

Here's a belt diagram to help you out. It's pretty difficult because it's a little tight in there to film putting the belt back on. Where we'll start is down on the right side with the power steering. Then, we'll put the belt up over the water pump, then down around the crank, and then up on our tensioner, under the idler pulley and then we'll pull the tensioner and get it onto the alternator.

Here, we're going to try to show you the best we can. You can see he's feeding it down over the power steering then up over the water pump. Then, he puts it up over the alternator, and down around the idler pulley. You can't really see it but he's trying to feed it down around the crank and then he's going to pull it up and place it on the tensioner. You can see, we can kind of see he's feeding it down around the crank right there. All that's left is getting it onto that tensioner. Now with the belt in place, you want to put that 15 millimeter socket on the tensioner. You want to push down on that. That will allow you to align the belt on all of the pulleys. Make sure you have it in place. Make sure you have it place and then you just want to tighten the tensioner back up. Just take that part of your intake and put it back down. Put it into position and just use a flat blade screwdriver to tighten up the clamp. Now, you can reinstall your air intake box. You can see there are two holes here. They line up with the two pegs on the van. You just want to feed that down in there. Get it into position. Then using a flat blade screwdriver, you just want to tighten up that clamp where it connects. You can see there, he actually loosened up the part of the intake he put in before this. He loosened it up just so he can angle it and push this part down. Then you just want to tighten both those clamps back up if you have to do that.

We'll just fast forward here. You'll want to put in those 10 millimeter bolts that secure the intake box and reconnect the harness. Then you want to realign your radiator overflow bottle. Put it into position and replace the 10 millimeter bolt in that.

In this video, we're going to be working with our 1996 GMC Sierra K1500. We're going to show you how to remove and replace your vehicle's serpentine belt on the 5.7-liter V8.

Here are the items you'll need for this repair: 3/8 ratchet

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.

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 am Mike Green, and I am one of the owners of 1AAuto. I want to help you save time and money repairing and maintaining your vehicle. I am going to use my 20 plus years experience, restoring and repairing trucks like this, to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly, that is going to save you time and money. Thank you, and enjoy the video.

This video, we will teach you how to remove and replace the serpentine belt 2000 Chevy S-10 Blazer Same for most of these blazers and Jimmy's, as well as the pick-ups, and Sonomas, with the 4.3 liter V-6.

Use an eight millimeter wrench and disconnect the negative side of your battery. You want to find your belt routing diagram, which is usually right here above your radiator. Just be familiar with it and how it shows you to route the belt. Sometimes the most frustrating part of this can be trying to get the belted routed again after you've taken it off. You don't know how it is supposed to be routed. So much make sure you understand basically what this is telling you and what it translates into as far as how your belt is routed.

Okay. Now you want to take a 3/8s drive ratchet handle, and 3/8s is the measurement of the square drive gear basically. You insert that... Your belt tensioner is right down there where I am going with the wrench, you can see it right there. You insert the drive into a square hole in the tensioner and then you turn the tensioner counterclockwise. You can see as I do that the belt loosens up and then you can slide it right off the idler pulley right there. Then release your tensioner. Now you are going to grab your belt, pull it off from the pulleys, and then just kind of pull it up and out, then off at the crank. There's your belt out.

Okay, to get your belt back on, you basically just want to follow the routing diagram. What I am going to do first is loop it down and around the crank pulley here, then up and around the water pump, then down around the power steering. I am not going to really be able to film that. I will film myself doing it but you won't be able to tell what I am doing. Basically, that's what you want to do first is go down around the crank, up and around the water pump, and then around the power steering.

Okay, so to do that I am going to take my belt. Just going to take a big loop and just push it right down and reach down into there. Sometimes you can get one hand down and guide it into the right spot. Now that I have it down and around the crank correctly. So we will go around the water pump. Then I will push a loop down over here. Go down and around the power steering pulley. Get off the crank just a little bit. So now the belt is loosely... Oops the belt came off. I will show you here.

Okay, so now you can see that the belt is really loosely routed down around the crank down there, the back up around the power steering pulley here, and obviously very loose. What we will do is pull on the tensioner and then we'll push this down and around the idler pulley. Take my 3/8s drive. Then push the tensioner down counter- clockwise as far as it can. Now I am pushing the belt down and around my idler pulley here. Let up on my tensioner. Just to quickly check. It is around the tensioner pulley, around the alternator, the idler, the AC, down and around the power steering, and it is pretty hard to see but way down in there it is around the crank properly. Now we can take our negative battery cable and reconnect it.

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 show you how to replace the serpentine belt on this 1996 Chevy Tahoe with the 5.7-liter V8 engine. The items you'll need for this is a new serpentine belt from 1AAuto.com, a 10mm socket and ratchet with an extension, and a 3/8" ratchet.

First, we need to just remove this cable. Just 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" ratchet, just push it into that square hole, and 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, then carefully let the ratchet up and pull it out. Then, remove your belt the rest of the way and pull it over that fan.

In the back is the old serpentine belt; up front is the new one from 1A Auto. They're identical, and they'll fit exactly the same. 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. 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" ratchet back into your tensioner, push down, and put the belt up onto the alternator. Then carefully release the ratchet and pull it out. Now, 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 Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20 plus years of 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'll be showing you how to remove and replace the serpentine belt on this 2002 GMC Sierra process is the same for many '99 to '07 GMC and Chevy Trucks with the 4.8, 5.3 and 6.0 litre engine. Only tools you'll need are flat blade screw driver, and a 15 millimeter socket and ratchet.

First, you want to move your intake hose by removing or loosening two clamps, one there and one there. We're going kind of speed up through this part here. You need your screwdriver to kind of pry in and break the rubber loose from the plastic, maybe twist it a little bit as well, and then pull it from the throttle body. Also a little clip that holds the radiator hose in, pry that out with your screwdriver as well. Then I'll install it back on my intake hose. Make it easier for later.

Now you can see tension is right here, so what you're going to do is take a 15 millimeter socket and ratchet. Put the socket on there. Move the ratchet clockwise, and that takes the tension off. You can pull the belt either off your tensioner, or I'm actually over here pulling it off of the idler pulley in the middle. Then, slowly release this back. It's going to actually go back further than original point. Now get your wrench back off. Now your belt winds around all its pulleys and down around the crank pulley. Let's pull it off and pull it right up.

To put the belt back on what you want to find is your routing diagram. We're going to be using this one right here. The solid belt is the one that we're going to be looking at. What you're going to do is actually feed it down and around your crank pulley first, then up and over your water pump around your power steering. Then up in here and then you'll pull. What I usually do is pull on here, and then pull it up onto the alternator. Of course I can't really film it that well, so you have to take my word for it that, that's what I'm doing. I'm going to take the belt feed it down and make a loop. Make sure it goes all the way around the crank pulley, up over the water pump here, down and around the power steering pump.

First, I went down and around my crank pulley, up and around the water pump with the backside of the belt. Then around the power steering pump. Now I have this part that I can hold, to put onto the alternator and put it there for a second. Here's my socket and my 15 millimeter bolt on my tensioner. While I pull this way on the tensioner, take the belt and pull it up, and onto the alternator, and the tensioner took over, and I'm just going to push it on a little more to my idler pulley here. It's pretty well centered. After you have the belt on, just a quick check. Make sure it's on all the pulleys. Look way down at the crank pulley and make sure that it's on correctly down there. Also, obviously, over here, the alternator and the power steering pulley, everything looks good.

We're going to fast forward through the section, which is just putting that tube back in, basically, and push in the rubber on to the plastic, tightening up the clamps and reinstalling that little clip that held the radiator hose to it. After that, you should be pretty much all set.

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 I'm going to show you how to replace a serpentine belt. This 2005 Chevy Silverado has the 4.3 Liter V6 so this procedure is the same for any Silverado or Sierra that has the 4.3 Liter V6 from 1999 through 2007.

The serpentine belt is pretty easy. First, make sure you find your belt diagram. This is the 4.3 Liter V6 so there's the diagram and it matches up with what's in the engine compartment. Removing the belt is pretty easy. Put a 3/8 inch drive ratchet right in here. Pull on that. See that loosens the belt. Move it from the idler pulley up top. Release that slowly. Then you pull your belt right off.

To put the belt on, you want to follow the pattern. You can't really see this but I'm going to go down around the crank pulley first, then I bring this up and around the water pump here. Then it goes from the water pump down to the power steering pulley here, up to the A/C pulley, across the tensioner and the alternator. I'm just going to reach down and make sure everything is pretty much on the way it should be. Now, you can press down when you see the belt starts to tighten up as you try and press it on to the idler here. Then we take our wrench, put it in, press down. That gives us the slack to put the belt right in here. Then just check. Make sure it's on all the pulleys correctly. It's in the grooves. It's actually not quite on there correctly, so pull it off here. Okay, the new belt is on.
