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 experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1Auto.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 removing and replacing the AC belt tensioner, which is down below on the engine. This is a 2002 with a six liter in it. Procedure's, basically the same for any 99 to 07 with the V8. Basically the 4.8, 5.3 and 6.0 liter are all the same tools you'll need are a flat blade screwdriver and a 3/8-inch drive ratchet with a small extension and a 15 millimeter socket.

Okay, you're going to start out by removing your intake hose assembly because you do need to remove that because you need to take the serpentine belt off first.

Okay, and we're going to kind of speed up through this part here. Use your screwdriver to pry in, break the rubber, loosen 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 to install it, back on my intake hose. Make it easier for later.

Okay, so now you can see your tensioner's right here, so we're going to do to take a 15 millimeter socket and ratchet. Put the socket on there, and then that takes the, you just move the ratchet clockwise and that takes the tension off. You can pull the belt either off of your tensioner, or I'm actually over here pulling it off of the idler pulley in the middle, and then slowly release this back. It's going to actually go back further than original point. I'll get your wrench back off.

Okay, you're going to want to remove this protecting plate. It's five 15-millimeter bolts. I'm just going to do it with an impact wrench real quick just to 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's our serpentine belt which we loosened. This is our tensioner for our AC belt, and this is our AC pulley over here. So you just want a 3/8 ratchet, goes right into the square hole here, and clockwise to release the tension, slip the belt back off the crank pulley.

Then you can take the belt, sneak it back around the pulley and off. So if you're wondering if this tensioner is making the squeaking noise, what you usually want to do is kinda come onto here and shake it back and forth a little bit. Even if you spin it, a lot of times it will be silent, but more so when you shake it back and forth. And I don't know if you can see that, but there's a little bit of play in it. So it's a good bet that it's been making some noise.

Okay, so you can see the tensioner as two bolts holding it, one there, then one over on the other side right there.

Okay, so I'm going to fast forward just to remove those two bolts. So my old pulley, new pulley from 1AAuto. You can see there, all the same. It's gonna mount all the same. Take my bolts, put them through. I'm gonna run my .. right up through here. Hold onto it while I start the bolts with the right hand. There are several bolts Put them on by hand, and then tighten them up. Tighten them up to about 40 to 45 foot pounds. And again, we'll just fast forward through me turning the wrench.

Okay. So 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. Feed it around the AC pulley. What I want to do is feed it around, get it set on the crank pulley here. Then I kinda set it up on the AC pulley as well. My ratchet with an extension, and push the belt up, put it in 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.

Okay. Then let my tensioner back. Feel all the way around my AC pulley, and feel all the way around the crank, and it's 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 millimeter bolts back in and tightening them up.

Okay. 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 so the solid belt is the one that we're going to be looking at, and what you're 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, so I'll kind of show you that. Can't really film it very well, so you have to take.

Okay, and of course, I can't really film it that well, so you kind of have to take my word for it. That's what I'm doing. So you can take your belt, feed it down, down, just kinda make a loop that goes all the way around the crank pulley, up over the water pump heater, down and around our steering pump.

Okay, so 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. And so now I have this part that I can hold, so put onto the alternator. Gonna sit it there for a second. Take my socket, put my 15-millimeter bolt on my tensioner.

Okay, and then while I pull this way on the tensioner, take the belt, and pull it up, and onto the alternator. Okay, and the tensioner takes over. I'm just going to push it on a little more to my idler pulley here. Make sure it's pretty well centered.

Okay, so 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.

Okay, and 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. And 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.

In this video, we're going to replace the serpentine belt tensioner on this 2002 Sierra with a six liter. The same procedure for any GMC or Chevy truck, 99' to 07' basically. With 4.8, 5.3, or six liter v8's. Tools you'll need, flat blade screwdriver, 15mm socket and ratchet with a small extension. Symptom of a bad belt tensioner is a squeaking from the front of your engine. Could also be your idler pulley. Just check out our other video to see the idler pulley removal and installation. First you want to move your intake hose. By removing, or loosening two clamps, one there and one there. We're going to speed up through this part here. Use your screwdriver to pry in, break the rubber loose and the plastic, Maybe twist it a little bit as well. Then pull it from the throttle body and also pry ... there's a little clip that hold the radiator hose in, pry that out with your screwdriver as well. Now I'm going to install it back on my intake hose, to make it easier for later.

Now you can see your tensioner is right here. What you're going to do is take a 15mm socket and ratchet and put the socket on there. Then that takes the ... you just move the ratchet clockwise and that takes the tension off. You can pull the belt either off of 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 the original point. Now get your wrench back off. Once you have your belt off, many times you can reach in here and spin these and hear some grinding or shaking, or shake them back and forth and you can there's some play in that pulley. This is your idler pulley here. Many times there is play, this one feels actually pretty good. There is also another tensioner on this vehicle. It's for the AC belt and you can see it right down in there.

You can see that belt is actually looking a little cracked, so I'm going to replace that as well. That will be on a different video, but that's something to keep in mind. You may take your drive belt off and realize that these ones really aren't the problem. Your noise might be coming from the AC tensioner down there. You can check out our other video to see that. To remove your tensioner there's three bolts. You can see one here, one down lower, and then there's one right down below there. Those are 15mm bolts. I'm going to use a 15mm socket with an extension and a ratchet and remove these bolts. I'm going to really speed through taking these bolts off. You don't really need to see me working a ratchet. Pretty all surprised on this truck, truck has got a lot of miles and it doesn't look like this has been replaced before. The bolts came loose pretty easy.

Then, as you probably see here, I actually used my fingers to loosen them or take them out most of the way. Here I am just removing the last top bolt. Now the tensioner comes up and out. Here you can see, here's the original tensioner, new tensioner from 1A Auto. All the same, going to mount the same. What I usually like to do is ... that actually goes in like that. Take our top bolt, put it in, put it down in, and start that top bolt. Take our bottom, long bolt, put it in, start it. Then our third bolt that's way down on the bottom, put it in and start, and then tighten them up. Once again, we'll fly through me just tightening these three bolts. When you tighten the bolts you want to probably give them a final tightening 30 to 35 foot pounds. 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, and then up in here. 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 film it very well, so you'll have to take ... 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. You can take your belt, feed it down, feed it down, and just make a loop. Make sure it goes all the way around your crank pulley, over the water pump here, and down and around the power steering pump. First I went down and around my crank pulley, up and around the water pump, with the back side of the belt. Then around the power steering pump. Now I have this part that I can hold to put onto the alternator.

I'm just going to set it there for a second. Took my socket, put it on my 15mm bolt on my tensioner. Then while I pull this way on the tensioner, I'll take the belt and pull it up and onto the alternator. Then the tensioner takes over and I'm just going to push it on a little more to my idler pulley 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. Also, obviously over here, the alternator and the power steering pulley. Everything looks good. We're going to fast forward though 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.

In this video we're going to be working with our 2002 Chevy Suburban 5.3-liter V8. We're going to show you how to remove and replace the serpentine belt tensioner. This is for the forward serpentine belt that runs all the accessories, with the exception of your air conditioning.

Here are the items you'll need for this repair: flat blade screwdriver, 15mm wrench, 15mm socket, ratchet, socket extension

Loosen the hose clamp just after the mass air flow sensor. This is going to be the second one back from your air box. We'll do this using a flat blade screwdriver. Wiggle and twist the boot to release it from the mass air flow sensor. You may need to use your screwdriver to help peel it back here. These tend to get stuck on pretty good. We'll also remove the one at the throttle body. We'll need to disconnect the hoses from their clamps here. You can either try prying it out there, or there's also a little clamp at the bottom here that you should be able to compress, pop loose with a flat blade, and remove the intake runner from the vehicle.

We've removed some things like the radiator fan and the fan shroud to make it easier to show you what's going on, but you shouldn't need to do this if you're doing this job at home. Before removing your serpentine belt, make sure your vehicle has a belt path diagram under the hood somewhere. If this is missing or faded, you can just draw another one onto the plastic with something like a paint marker. Using a 15mm wrench on the tensioner, rotate the nut clockwise to slack the belt. Pop the belt off of whatever pulley is easiest for you to reach. Let the tension off the pulley and remove your serpentine belt.

You need a 15mm socket, ratchet, and extension to remove the three 15mm bolts on the tensioner bracket.

Reinstall the serpentine belt tensioner onto the water pump housing cover. Two longer bolts go in the upper holes, and the shortest bolt goes in the bottom. Tighten these bolts with a 15mm socket and ratchet.

Install the belt over the front grooves of the harmonic balancer or crank pulley. Bringing the right side over top of the pulley. We'll then go over top of the water pump and loop under the power steering pump, over the alternator, under the idler pulley. I'll keep this piece in my hand. Make sure that everything is seated because this one's kind of tight and you're going to want the room. Using my 15mm wrench, we'll take the tension off of the tensioner pulley, slide the belt over, double-check that our path is right, all of the belt is properly seated, and then let the tension back on.

Reinstall the intake tubing. It's easiest to set it onto the throttle body. Reengage the hoses into their clips and then get the boot over the air box. Then tighten down both clamps with a flat blade screwdriver.
