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 engine serpentine belt. This is a 2011 Silverado 1500. It has the 5.3-liter engine. This process is the same for many SUVs: the Yukons, Tahoes, as well as Sierras and Silverados with this 5.3-liter. The only tool you'll need is a 15 millimeter socket with a ratchet.
Your serpentine belt is right here, and you can see this is your tensioner, right here. What you want to do is use a 15-millimeter socket and ratchet. You just push that down and then you can pull your serpentine belt off all the pulleys.
When you go to put your serpentine belt back on, it's important that you do it in the right order. You're going to want to use this belt diagram as a reference, just to make sure. When you put your belt back on, it should look exactly like this diagram. The red belt in the picture here is your AC belt. It's a separate belt entirely.
It's a little hard to video, but we'll do our best. He puts a loop down around the power steering pulley there and then comes up around the water pump and down around the main crank pulley. All the while, he's holding it on the alternator and then he puts it over on the tensioner. Basically, he's got the belt routed 100% except for the middle idler pulley. Now he pulls it down near the idler pulley and he's going to grab the wrench, put it on the tensioner, push the tensioner down, and push the belt underneath the idler pulley there. Then just check it and make sure it's on all the pulleys correctly.

Okay, so you don't have to remove the intake tube here to do your serpentine belt, but it just makes it a lot easier to film. So, we're going to start by loosening this tensioner, which tensions the drive belt. But before removing your belt, there's usually a belt path diagram under the hood somewhere. This truck doesn't have it, but you can also take note of it, and draw your own on a piece of paper. So, we're going to take a 15 mm socket, and a breaker bar, and put it on the tensioner. Going to push it down to loosen it. Can pop the belt off. It's just going to come right off. Then you can slowly let the tensioner go back. That's about as far back as it's going to go. Let's see if I can get it up, over the hose here. Then pull the breaker bar off.
All right, so this is the old belt here. It's pretty worn out, you can see it's getting glazed. Inside, the ribs are pretty worn. Even had a little pin hole here, right here, there's a little pin hole in it, so that's no good. This is the new belt from 1AAuto.com. You can see it's got the same amount of ribs, it's the same width. It's just brand new. That's going to fit great. It's a perfect match in length to the old belt as well.
Okay, now we're going to install our serpentine drive belt. Lay it down, like that. Then run it up, around the idler pulley, over the alternator. Down around the power steering. Goes up and over the water pump. And goes back, down around the crank pulley. Make sure it's sitting in all the pulleys as you go around them. It's sitting in all the pulleys. Can actually pull it tight a little bit. Then take our breaker bar, slide breaker bar around the belt, so I can push it down. Feed the belt over. Make sure it stays in the crank pulley. Can get a little tricky. Kind of walk it over the pulley tensioner. This pulley's new, so it's not as stretched out as the old one, so it's going to be a little bit more difficult to get on. But just before you release it, make sure it's around all the pulleys, and seated in the grooves. Once you're sure it's like that, just gently release the tensioner. You can see it's nice and tensioned up. And it's looped around all the pulleys.

So, to get started on doing your serpentine belt, you want to make sure your engine is off, obviously. Once you've done that, you want to make sure that you pay attention to the belt routing, so you know exactly the way that the new belt is going to go on. If you were to follow the belt coming over in this direction towards the passenger side, this upper pulley right here is the tensioner. You're going to get on that with either a 15-millimeter wrench or, of course, your serpentine belt tool. I'm going to turn that clockwise. It's going to relieve tension, and I'll take the belt right off. I'll bring this up here, so it hangs out. Now, I'm going to remove the belt. There it is, friends.
When I'm doing these serpentine belts, the first place I like to start is way down at the bottom at the crank. So, I'm going to take one of my ends, put it down along the bottom of that crank, and try to get the belt, so the grooves sit on the grooves of the actual crank pulley. I'm going to bring this around. And now, I'm going to line it up with the direction that the belt originally ran, coming around to the water pump here. Back down around the power-steering. Up over the alternator. Down under the idler pulley.
Okay. So, this looks good. Have it around the tensioner. I'm going to double-check to feel as though it goes around all the pulleys. Oh, look right down here, I can see it's coming right off that power steering pulley. Loosen up the belt a little bit. Slide it in. This looks good. The next thing I want to do is relieve tension from the tensioner, and slide the belt underneath the smooth pulley of the idler. Slide this right over the idler. Carefully release. Now, what I want to do is I want to check to make sure that the belt is sitting on all the pulleys flush.
If you have it hanging over, there's pretty good odds that you're going to damage your belt, and you're going to have to re-replace it again. That feels good. Ok this one. Yeah. Perfect. We'll get our tool out of here, and then we'll start it up and check it.
That looks good. Let's go ahead and start up the vehicle. We're going to run it for approximately 15 seconds, turn it back off, and then double-check.

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.
