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.

I want to help you save time and money repairing and maintaining your vehicle. I've been using 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 be showing you how to replace the AC belt, which is a smaller belt, down below on these engines. This is a 2002, with a six-liter. This is the same as basically any '99 to '07 with a V8 4.8 liter, 5.3 liter or 6.0 liter. The tools you'll need are a flat blade screwdriver, a 15-mm socket with a 3/8 ratchet and extension.

You're going to start out by removing your intake hose assembly because you do need to remove that because you would need to take the serpentine belt off first. We're going to speed up through this part here. Use your screwdriver to 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 and also pry it. There's a little clip that holds the radiator hose in. Pry that out with your screwdriver as well.

Now install back on my intake hose to make it easier for later. Now you can see your tension's right here, so what you're going to do is take a 15-mm socket and ratchet and put this socket on there and you just move the ratchet clockwise and that takes the tension off. You can pull the belt either off of your tension, or I'm actually over here pulling it off of the eyelet pulley in the middle and then slowly release this back.
It's going to actually go back further than the original point. That will get your wrench back off.

You're going to want to remove this protection plate. It's five 15-mm bolts. I'm going to do it with an impact wrench real quick. Make it fast, and I'll make it even faster by hitting the fast forward button. Now you can easily see up in here. Here is our serpentine belt, which we loosened. This is our tensioner for our AC belt and there is our AC pulley over here. You just want a 3/8 ratchet, goes right into this square hole here, and clockwise, release the tension, slip the belt back off the crank pulley and then you can take the belt and snake it back around and pulling it off.

You can see this belt; it's in pretty rough shape. You're going to take your new belt and feed it up over the crank, behind the other serpentine belt, and I just put it right in behind. I feed it around the AC pulley. What I want to do is feed it around and get it set on the crank pulley here.
Then I have set it up on the AC pulley as well, but a ratchet with an extension and push the belt up within there, pull that down, flip that up on top of the tensioner pulley, then reach in from the side here, and put my belt correctly onto my AC pulley. Then, let my tensioner back and then feel all the way around my AC pulley and see all the way around the crank and its all set on there.

Now, you're going to put the shield back on, and I'm just going to fast forward through that. It's nothing more than putting those 15-mm bolts back in and tightening them 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 and 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 and 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.
I'll show you that. You can't really feel it very well. Of course I can't really can't film that well, so you'll have to take my word for it that that's what I'm doing. You can take your belt, feed it down and just make a loop that goes all the way around the crank pulley, over the water pump here and down and around our steering pump.

First I went down and around my crank pulley, up and around the water pump with the backside of the belt and then around the power steering pump. Now I have this part that I can hold to put onto the alternator. I'll just put it there for a second. I'll move my socket around my 15-mm bolt on my tensioner.
Then while I pull this way on the tensioner, I take the belt and pull it up and onto the alternator. Then the tensioner takes over and then I'm just going to push it on a little more so my idle is over here. Make sure 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, and also, obviously, over here, the alternator and the power steering pulley. Everything looks good.

We're going to fast forward through this section, which is just putting that tube back in basically and pushing the rubber onto 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. We've been selling auto parts for over 30 years!

What's up, guys? I'm Andy from 1A Auto. Today I'm gonna show you how to remove and reinstall the serpentine belt on this 2008 Chevy Silverado with a 4.3L V-6 engine. If you need parts for your vehicle, click the link in the description and head over to 1aauto.com.

One thing you want to keep in mind, when you're doing a serpentine belt is which routing the belt is. Before you take it off, it's a good idea to take a picture with your phone. If you don't have any reference of the belt, sometimes there's a key on the vehicle itself. This vehicle does not have it.

We will take this serpentine belt tool, we actually sell this at 1aauto.com. Slide the tool into the tensioner, right here. And then there's a hose over here that's kind of in your way a little, so pull up on the tensioner. Just going to hold this. Make sure you don't have anything in the path of this. You don't want to slip and let go of this and have it hit you in the face or anything.

So, we'll pull up on this. We're going to pull the belt off of this idler, right here. We will pull it off the alternator. Pull it off the tensioner. Pull it off the crank, the water pump, the power steering pulley, and then off the AC compressor. Then I'll slide this belt over the tool and pull it out. There's the belt.

A good thing to practice when you're doing this is to take the new belt and line it up with the old belt, and make sure they're the same length. We don't have a new belt, so we're just going to reuse the old one.

All right, we're going to remove this tool before we put the belt on. It'll just make it easier to maneuver the belt around to position. So, first we're gonna install the belt on the crank pulley. Slide it over the water pump, and over on the power steering pulley, up around the AC compressor, and over the water pump. We're going to skip the idler, for now, 'cause we'll put that on last. Over to the tensioner.

So now that those are all lined up, I can take the belt tool, slide this in position, and put some tension on the belt. Slide this up, and slide it under the idler pulley. Remove the tool. Then check all the pulleys, and make sure the belt is in position and hasn't jumped off any of the teeth. And that looks pretty good.

Then we can just start it real quick and then shut it off, and just make sure everything is still in position.

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 have to replace the serpentine belt on this 2002 Chevy Suburban with the 5.3 liter V8 engine and the 130 amp alternator. The items you'll need for this are a new serpentine belt from 1AAuto.com, a 10 and 15mm socket and ratchet and a flat blade screwdriver.

Start off by loosening these two hose clamps, using a flat blade screwdriver. We'll just fast forward as Don does this. Now, 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 10 millimeter bolts. We'll fast forward as Don does that. Then, 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 will fast forward as Don does this to the other three. Now, just pull that hose back and lift the shroud straight up and out.

Right here is your tensioner. Just put the 15 millimeter socket and ratchet on it and push down on the ratchet. This will release the tension on the belt and you can pull the belt from the pulleys. You want to just reach down and pull it off all the pulleys and the belt will be free and you can just pull it up and out.

Now, located on the front of your truck, you will see this serpentine belt diagram. You want to follow this when you're putting your belt back on. Really, it's hard to show us doing it. So, you're going to have to refer to that but it's pretty simple to follow. Everything is where it needs to be. You can see he starts with the lower pulleys. He just starts feeding the belt down around each of them, following that diagram. We'll fast forward as he does the majority of this. Once you've got it on all but one pulley, push back down on the tensioner and double check. Make sure your belt's on all the pulleys properly and not just half on some of them. Then just get it in to position and then carefully release the tension on the tensioner and pull the ratchet free.

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

Take the air intake hose and push it back down in to place on to the air intake box and then on to the engine. Then just tighten up those two hose clamps and just re-clip that hose to the air intake hose and you're 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, 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.
