2002 Chevrolet Silverado 2500 HD V8 6.0L Air Conditioning 2 Piece Serpentine Drive Belt Component Kit TRQ BPA05089

Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the internet. 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 part 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 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.

If you were to look right down here, you're gonna see a clamp. If you were to look at the other end where it connects on to the throttle body, you're gonna see another clamp. You can go ahead and loosen those up. Also, if you come right up here, you're gonna see an 8-millimeter bolt, look, if you loosen that up, you can take this right out. Once you have that out of the way, and the clamps are loosened, you can wiggle this around. I'm gonna draw it off of the throttle body right here, and I'm gonna take them right there. Take it off of right here, remove it from the vehicle. So now that we have the intake and the little shell out of the way here, it gives us a nice, clear view. You don't necessarily need to take off the shell but I just like to have it out of the way. Go ahead and relieve your tension like that. And then, I'm just gonna take the belt off of the idler pulley here, and then I can let go of that. We'll get our serpentine belt right out of the way. Let's go ahead and remove the belt. Okay, looking at our new tensioner, you can tell that you're gonna have three mounting bolts. I'm gonna use my 15-millimeters socket and my ratchet and I'm gonna remove all 3. There will be one located here, one located much lower, down near thermostat housing, and then, also one over towards the driver's side top. Start with the hardest one.

Here's our tensioner friends. Now, once you confirm that your new tensioner is correct and it matches the original, it's time to get the bolts and everything back in. You're gonna notice that two of your bolts are long and one short. The short bolt is going to be the lowest bolt, the other two longer bolts are going to be the upper bolts. I always start in all of my bolts before I tighten any of them up completely. Now, it's time to torque these. Torque them to 37 foot-pounds. All right. Go ahead and take one side, go down and around the passenger's side of the water pump which is this right here, and then, put it over the crank, which is the main pulley over there. I'm just gonna circle it. Put it up and then slide it around. I'm gonna take one, and I'm gonna come up and over the tensioner right here. And then, the other side. I'm gonna bring it down and around the water pump and then underneath the power steering pump. It's gonna fit right inside the ribs perfectly. Then, I'm gonna come up, make sure it's sitting in those ribs. There it is. Come up and over the alternator right here. This looks good. Make sure everything is situated approximately where it needs to be. That looks great. I'm gonna grab my tensioner tool. Put it on there, relieve tension. Now, I'll take this, bring it right underneath the idler pulley. This is your idler pulley. Get our tool off, give it a nice tug. And then of course, double check all of your pulleys. Every one of them that has the rib side that goes up against the belt, you need to make sure it is sitting perfectly inside the ribs. If you're wondering what your belt routing should look like, you can find it right on the front. Get our intake back on here, it's gonna go right underneath this hose here. Line it up there. Grab this, slide it in. Push it all the way in so it's up against the whole throttle body. Make sure your clamps are nice and tight. Your hose over here should have a little clippy-do. Ours is actually broken but it's going to push in right there and that will hold it secure. Put this cover back on here, just slide it all the way back so it's sitting inside the pitons. Put this down and tighten up your bolt.

If you were to look right down here, you're gonna see a clamp. If you were to look at the other end where it connects onto the throttle body, you're gonna see another clamp. You go ahead and loosen those up. Also, if you come right up here, you're gonna see an 8-millimeter bolt. If you loosen that up, you can take this right out. Once you have that out of the way, and the clamps are loosened, you can wiggle this around. I'm gonna draw it off of the throttle body right here, and I'm gonna come right there, take it off of right here, remove it from the vehicle.

So now that we have the intake and the little shell out of the way here, it gives us a nice, clear view. You don't necessarily need to take off the shell but I just like to have it out of the way. Go ahead and relieve your tension like that. And then I'm just gonna take the belt off of the idler pulley here and then I can let go of that. We'll get our serpentine belt tore right out of the way. Let's go ahead and remove the belt. Go ahead and take one side, go down and around the passenger side of the water pump, which is this right here, and then put it over the crank, which is the main pulley over there. Just gonna circle it, put it up and then slide it around. I'm gonna take one and I'm gonna come up and over the tensioner right here, and then the other side. I'm gonna bring it down and around the water pump and then underneath the power steering pump. It's gonna fit right inside the ribs perfectly. And then I'm gonna come up. Make sure it's sitting in those ribs. There it is. Come up and over the alternator right here. This looks good. Make sure everything is situated approximately where it needs to be. That looks great. I'm gonna grab my tensioner tool, put it on there, relieve tension. Now I'll take this, bring it right underneath the idler pulley. This is your idler pulley. Get our tool off, give it a nice tug, and then of course double-check all of your pulleys, every one of them that has the rib side that goes up against the belt, you need to make sure it's sitting perfectly inside the ribs.

Wondering what your belt routing should look like? You can find it right on the front. Gonna take back on here. It's gonna go right underneath this hose here, line it up there, grab this, slide it in, push it all the way in so it's up against the whole throttle body. Make sure your clamps are nice and tight. Your hose over here should have a little clippy-do. Ours is actually broken. But it's gonna push in right there and that will hold it secure. This cover back on here, just slide it all the way back so it's sitting inside the pitons, put this down and tighten up your bolt.

Remove the negative terminal from the battery. Just use a 8-millimeter wrench and just slide that out of the way. Take this cover off. You can just use a 8-millimeter socket. Remove this bolt. Just pull the cover up and slide forward. Loosen up this worm clamp right here. Use a straight blade screwdriver. Loosen this clamp as well. Take this hose bracket off of the intake. Just use a trim tool and pop this off just like that. Grab it right here. Just rock it back and forth, sliding it forward and also right here. Pop it off and pull it up. Now you're gonna use a serpentine belt tool. We're gonna use the 15-millimeter adapter on the end of it. If you don't have one, you can just use a 15-millimeter wrench. Just be careful. Loosen up the tension on it as if you're turning it clockwise and then over on the idler, just take the belt off. Release the tensioner. Pull off your tool. Take the belt off. I'm just gonna take it off the harmonic balancer with a crank pulley. Slide it off the tensioner. Slide it over the water pump just to keep it out of the way. If you're just doing the AC belt down below, you can just leave the belt off at this point. You wouldn't have to take it off all the way. If you're replacing it, take it off the alternator, off the power steering pump and the idler pulley.

Take this shield off. There's a bolt there, bolt there, there. Sometimes there's three bolts here. Sometimes just two. Use a 15-millimeter socket. And take the cover down. Now the belt has broken on this vehicle so I don't have a belt on here but if you needed to remove the belt first, just use a 3/8 drive ratchet and a extension and just go into the tensioner right here and then in clockwise motion, loosen up the tension on the belt. Slide the belt off. You're gonna take the belt off behind the harmonic balancer or the crank pulley and it loosen the tension up and just slide the belt all the way off. Now take a 15-millimeter socket. Remove the two bolts in the bottom of tensioner. And slide it out. Take the new tensioner and put it back in position. Take the bolts. Get the bolts started. And tighten the bolts down. And torque these bolts to 37 foot-pounds. Take the new belt. Go over the crank pulley. You're gonna go behind the crank pulley and then go over to the AC compressor, get it around the pulley and then around the tensioner pulley. All right. Once that's all lined up from there and take your socket and extension or ratchet and extension and pull the tension off the belt as you slide the belt on the rest of the crank pulley. Just make sure it's on there good, in all the grooves. And it looks good.

Take this cover, bolts lined up. And snug them all up. All right. Take the serpentine belt. I'm gonna go around the crank pulley down below and come up. Take one side of the belt. Just go over the tensioner pulley. The other side goes on...back side goes over the water pump and then you're gonna go down around the power steering pump pulley and then up to the alternator. Take your belt tensioner tool, carefully while you're holding the belt near the idler pulley over here. Take the tension off the tool, the tensioner, and slide it onto the idler. Just double check, make sure the belt is up over all the pulleys. It looks good. Take tool off. Should be good. Take the snorkel, line it up. Put on the throttle body and then over here on the airbox or over the mass airflow sensor, hook this holder on just like that. Your straight blade screwdriver. Tighten up the worm clamp. Snug that up and tighten this one up. Very good. Slide the cover in position. And tighten down the bolt. Take the negative terminal. Connect it to the battery. Use a 8-millimeter wrench and tighten it up. Just make sure it's not wiggle loose. Looks good.

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.

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.

You remove this cover. There's a bolt right here. Use an 8-millimeter socket. Take that out. And slide the cover up and slide it forward. There's a bracket right here that holds the coolant hoses on. Just use a trim tool and just separate that from that. This one's broken in this vehicle. Now we wanna remove the snorkel and use an 8-millimeter socket, loosen up the worm clamp or you can use a straight blade screwdriver. So right here. Slide this off. And slide it off the throttle body. And pull it out of your way.

And use a 15-millimeter wrench or you can use a belt tensioner tool and just put it on the belt tensioner, loosen this up. Slide the belt off of the idler pulley. Loosen up on the tensioner and slide the belt off the alternator, off the power steering pump pulley, off the water pump, and off the crank pulley. Now your vehicle may have a shield right here. There should be two bolts down below and then two or three bolts up top. They're 15 millimeters. Use a 15-millimeter socket, take that shield down. I'm gonna take a ratchet with a 3/8 extension and slide it right into there of the tensioner. Loosen up the tension on the belt. Then slide the belt behind the crank pulley just like that. Then take the ratchet off. You can slide the belt over the AC compressor and slide it off the crank pulley. And there's two bolts on the AC tensioner. Use a 15-millimeter socket, remove those 2 bolts. All right. Take those bolts out. And just grab the tensioner and slide it out. Take the new tensioner and put it in position. Take the bolts. Get them started. And now I can torque those bolts to 37 foot-pounds.

Take the belt. You can go over the crank pulley and then go behind it. And then slide it over the AC compressor. Get that lined up. And then try to get the belt over the top part of the crank pulley. And make sure it's over the tensioner. And you can try this this way or the opposite way. You could have the belt on this side. Then we'll take the ratchet. As you pull a little bit of tension on the belt, then move the tensioner down and just walk the belt onto the pulley. Oops, slipped off. Can try to slip it over the tensioner like this as well. It's not as easy. Oops. And slip it over. And just make sure the belt is all the way around the pulleys and the AC pulley. And that looks good. And if your vehicle had a shield right here, you wanna replace that shield at this time.

All right. Take the serpentine belt and slide it over the crank pulley first and go over the water pump. The back side of the belt needs to go over the water pump. And go down to the power steering pump and up over the alternator. And then over the tensioner right here. And you hold off on putting it over the idler pulley till last. And now take your belt tensioner tool or a wrench and just take the tension off the tensioner. All right. Now I'm gonna slide the belt close to the idler pulley and take the tension off the tensioner with your wrench or your belt tension tool. Just be careful. And take the wrench off and just double-check all the pulleys. And it looks good. Now take the intake snorkel and line this up with the throttle body. And that's good there. And line it up on the mass airflow sensor just like that. And tighten this up. Tighten up that worm clamp and then same with this one. And take this bracket and then reposition that into that bracket. This one's broken. And slide this cover back on. Get this bolt started. And tighten that up.

You remove this cover. There's a bolt right here. Use an 8-millimeter socket. Take that out. Then slide the cover up and slide it forward. There's a bracket right here that holds the coolant hoses on. Just use a trim tool and just separate that from that. This one's broken in this vehicle. Now we wanna remove this snorkel and use an 8-millimeter socket. Loosen up the worm clamp. Or you can use a straight blade screwdriver. So right here.

And slide this off. And slide it off the throttle body. And pull it out of your way. And use a 15-millimeter wrench or you can use a belt tensioner tool and just put it on the belt tensioner. Loosen this up. Slide the belt off of the idler pulley. Loosen up on the tensioner and slide the belt off the alternator, off the power steering, pump pulley, off the water pump and off the crank pulley. Now use a 15-millimeter socket and there's 3 bolts holding the tensioner on. Take those three bolts out. And slide that out. All right. Take the new tensioner and you have those three bolts. Two of them are longer. One of them is shorter. And the longer ones go on the longer part of the bracket. The shorter one goes on the shorter part.

And I'm gonna torque these bolts to 37 foot-pounds. Right. Take the serpentine belt and slide it over the crank pulley first. And go over the water pump. The back side of the belt needs to go over the water pump. And go down to the power steering pump. And up over the alternator. And then over the tensioner right here. Then you hold off on putting it over the idler pulley till last. And now take your belt tensioner tool or a wrench and just take the tension off the tensioner. Right. Now I'm gonna slide the belt close to the idler pulley and take the tension off the tensioner with your wrench or your belt tension tool. Just be careful. And take the wrench off and just doublecheck all the pulleys. And it looks good.

Now take the intake snorkel and line this up with the throttle body. And that's good there. And line it up on the mass airflow sensor. Just like that. And tighten this up. Tighten up that worm clamp and then same with this one. And take this bracket and then reposition that into that bracket. This one doesn't...this one's broken. And slide this cover back on. Get this bolt started. And tighten that up.

You remove this cover, there's a bolt right here. Use an 8-millimeter socket, take that out, and slide the cover up, slide it forward. There's a bracket right here that holds the coolant hoses on, just use a trim tool and just separate that from that. This one's broken in this vehicle. Now we wanna remove the snorkel and use an 8-millimeter socket, loosen up the worm clamp, or you can use a straight blade screwdriver. So right here. Slide this off and slide it off the throttle body and pull it out of your way. And use a 15-millimeter wrench or you can use a belt tensioner tool and just put it on the belt tensioner, loosen this up. Slide the belt off of the idler pulley. Loosen up on the tensioner and slide the belt off the alternator, off the power steering pump pulley, off the water pump, and off the crank pulley.

All right, take the serpentine belt and slide it over the crank pulley first and go over the water pump. The backside of the belt needs to go over the water pump. And go down to the power steering pump and up over the alternator. And then over the tensioner right here and you hold off on putting it over the idler pulley till last. And now take your belt tensioner tool or a wrench and just take the tension off the tensioner.

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 how to replace the A/C serpentine belt tensioner on this 2002 Chevy Suburban with a 5.3 liter V8 engine. It's the same part and similar process on these Suburbans from 2000 to 2008. The items you'll need for this are a new A/C belt tensioner from 1AAuto.com, 10mm and 15mm socket and ratchet, flat blade screw driver, and a 3/8 inch ratchet.

Start off by loosening these two hose clamps using your flat blade screw driver. 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 and then pull forward and lift it up and out.

Next, remove these two 10mm bolts and we'll fast forward as Don does that. Then pry the clip on this hose out of the fan shroud, and 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'll fast forward as Don does this to the other three. Then just pull that hose back and lift the shroud straight up and out.

Right here is your tensioner. Just put the 15mm 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, pull it off all the pulleys, and the belt will be free. You can just pull it up and out.

Underneath the front bumper, you'll see this plate and you need to remove these five 15mm bolts. We'll fast forward as Don removes those. Behind the plate, is your A/C belt tensioner and you just use a 3/8 inch ratchet. Just pull down on the tensioner and then pull your A/C belt free. It pulls right off. Right here is your A/C belt tensioner. Sorry for the shaky camera, but you can see it's held in with two 15mm bolts and we'll just fast forward as Don removes those. Then the A/C tensioner will just pull right off.

On the left is the old A/C belt tensioner. On the right is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same. Put your new A/C belt tensioner into place and replace those two 15mm bolts. We'll just fast forward as Don tightens those up. Feed your new A/C belt back up into place and for now, you're really just preliminarily getting it into place, and then, use your ratchet on the tensioner. Now make sure the belt is on all the pulleys and that it's on all the way. Once the belt is in the right position on each of the pulleys, carefully release the tension on the tensioner and pull your ratchet free. Put the skid plate back up into place and replace those five 15mm bolts and tighten them up.

Now, located at the front of your truck, you'll see this serpentine belt diagram. You want to follow this when you're putting your belt back on and 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 and you can see he starts with the lower pulleys. He just starts feeding the belt down and 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 is on all the pulleys properly and that it's not just half on some of them. Then just get it into position. Then carefully release the tension on the tensioner and pull the ratchet free.

Now to replace the shroud, just push it back down into place. Then, replace those four clips. Just push them back down into place and push the center down to lock them. Push the hose back into place, and then, replace those two 10mm bolts. Now take this air intake hose and push it back down into place on the air intake box and then onto the engine. Then just tighten up those two hose clamps. Then just re-clip that hose to the air intake hose and you're all set.

If you were to look right down here, you're gonna see a clamp. If you were to look at the other end where it connects on to the throttle body, you're gonna see another clamp. You can go ahead and loosen those up. Also, if you come right up here you're gonna see an 8-millimeter bolt, if you loosen that up you can take this right out. Once you have that out of the way and the clamps are loosened, you can wiggle this around. I'm gonna draw it off of the throttle body right here, and I'm gonna take them right there. Take it off of right here, remove it from the vehicle. So now that we have the intake and the little shell out of the way here, it gives us a nice, clear view. You don't necessarily need to take off the shell but I just like to have it out of the way.

Go ahead and relieve your tension like that. And then, I'm just gonna take the belt off of the idler pulley here and then I can let go of that. We'll get our serpentine belt right out of the way. Let's go ahead and remove the belt. Let's remove the five bolts that hold up your skid plate. Now that that's out of the way, we have a clear view of the AC belt tensioner right there. Go ahead and use a 3/8 ratchet with a short extension. Put it right in the slot. When you pull this down, it's gonna relieve tension, and then, we'll just get the belt right off of there. There we are. Take that off of there. I'm gonna take it, I'm gonna go over that AC compressor. And then, I'm gonna start over the top of the crank. Now that we have that up and over the crank, and then, it's heading its way over to the AC pulley, I'm gonna go ahead and pull this down, give myself a little bit of slack. Put the belt up over the tensioner, and then, just start working it over the AC clutch itself. When you do this, you want to try to be as straight as possible because if you come in at an angle, it's not gonna fit very well. Okay, I relieve tension. Now, you just want to check that belt, feel all the way around, make sure it's on the crank perfectly. Now, we're gonna go and put our shield back up on here.

Go ahead and take one side, go down and around the passenger side of the water pump which is this right here, and then, put it over the crank which is the main pulley over there. I'm just gonna circle it. Put it up and then slide it around. I'm gonna take one, and I'm gonna come up and over the tensioner right here. And then, the other side I'm gonna bring it down and around the water pump, and then, underneath the power steering pump. It's gonna fit right inside the ribs perfectly. And then I'm gonna come up, make sure it's sitting in those ribs. There it is. Come up over the alternator right here. This looks good. Make sure everything is situated approximately where it needs to be. That looks great. I'm gonna grab my tensioner tool. Put it on there. Relieve tension. Now, I'll take this, bring it right underneath the idler pulley. This is your idler pulley. Get our tool off. Give it a nice tug. And then, of course, double check all of your pulleys. Every one of them that has the rib side that goes up against the belt, you need to make sure it is sitting perfectly inside the ribs. If you're wondering what your belt routing should look like, you can find it right on the front. We'll get our intake back on here. It's gonna go right underneath this hose here, line it up there. Grab this, slide it in. Push it all the way in, so it's up against the whole throttle body. Make sure your clamps are nice and tight. Your hose over here should have a little clippy-do. Ours is actually broken, but it's going to push in right there and that will hold it secure. Put this cover back on here, just slide it all the way back so it's sitting inside the pitons. Put this down and tighten up your bolt.

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.
