In this video we're going to be working with our 2006 Ford Explorer. We're going to show you how to move and replace your vehicle's serpentine belt tensioner. If you like this video, please click 'Subscribe'. We have a ton more information on this and many other vehicles. If you need this part for your car, you can follow the link down in the description over to 1AAuto.com. Here are the items you'll need for this repair.

Loosen the clamp on the air box side of the intake duct with a flat blade screwdriver. You'll then want to disconnect the breather lines. There's a little green tab here that you just pull back and pop them off. You'll then need to undo the clamp on the throttle body. You'll then want to remove the intake duct.

For some jobs like your alternator or idler pulleys, it may not be necessary to remove the belt fully. However, if the pulley has been dragging from a bad bearing or a weak alternator, it's probably damaged your belt a bit too and it's not a bad idea to replace it while you're in here.

Using a 1/2" drive ratchet, place it into the square drive of the serpentine belt tensioner and rotate the tensioner clockwise to release pressure and remove the belt from one of the pulleys. It's usually easiest to do this from a smooth pulley. Then carefully release tension and remove your ratchet. Remove the serpentine belt from under the A/C compressor and then pull the loop up and through over your tensioner. You'll then want to get it out from under the crack where it loops over the water pump. You've already unhooked it from the idler pulley on this side so loop it out from the grooved idler pulley and the power steering pump and remove your belt.

Remove the three ten millimeter bolts along the top of the serpentine belt tensioner with the ten millimeter socket and ratchet. You can then remove your tensioner from the vehicle.

Here we have our old tensioner that we removed from our vehicle and our new part from 1AAuto.com. As you can see, these parts are exactly the same with the same half inch square drive, same arm and spring mechanism, the same three bolt mounting flange and the same pulley on the bottom. This tensioner is responsible for keeping your serpentine belt up as tight as it can until the belt has stretched past its limits, however the spring mechanism can fail, overtensioning or undertensioning the belt as well as the pulley itself going bad. If you have any of these problems, this new part from 1AAuto is going to go in direct fit, just like your original equipment, and fix you up right.

Reinstall the serpentine belt tensioner along with its three ten millimeter bolts. Once you've got the bolts started, go ahead and tighten them down with your ten millimeter socket and ratchet.

Now reinstalling the serpentine belt on this is going to be pretty difficult to show. You want to start with a loop and send it down and around the crank pulley. Now you're going to take the passenger side of the belt and bring it down between the tensioner and the A/C compressor at the bottom of the motor. With the right side of the belt, you're going to go up and over the water pump pulley all the way to the button of the motor on the driver side, where you'll go under the grooved idler pulley, as well as under the power steering pump pulley. Install your 1/2" drive into the tensioner and rotate it clockwise to release the belt tension. It's usually easiest to get over the alternator, then move your hand to the other side of the engine and go under the smooth idler pulley on the driver side, and then just use a light or your hand to check the belt path and make sure that everything went over and under all the pulleys currently and that it isn't hung up anywhere.

Reinstall the intake duct and pop on the two breather connections, then tighten it down with a flat blade screwdriver.

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 a serpentine belt tensioner on this 2005 Ford F150 with the 4.6L V8 engine. The items you'll need for this are a new serpentine belt tensioner from 1AAuto.com, a 1/2" ratchet, piece of pipe for some extra leverage, a 10mm socket and ratchet, a torque wrench, and a flat blade screwdriver.

Using your screwdriver, just loosen up the hose clamp here and right here. Then push the tab on this hose and pull it free. Then pull your air intake hose free.

Now, your serpentine belt tensioner is located right down here. Using a 1/2" ratchet or breaker bar you just want to insert it into that square hole on the tensioner. Then, using a piece of pipe for some extra leverage, just pull the tensioner back and it will loosen up the belt. You can lift the belt up and off the alternator. Then just carefully let the ratchet back down and pull it free. Now you can pull your belt up and out.

Reach way down and pull the belt off of the AC compressor pulley first, which is way down to the left as you're looking at the front of the engine. Then, once it's off of that, go down and pull it off of the crank pulley, which is right in the center of the engine.

Now to remove your tensioner, you want to remove these three 10mm bolts. We'll fast-forward as Mike removes those. You can see he decided to use air-powered tools here. You can do that as well. It just speeds up the process. Then your tensioner will pull free. On the bottom is the old serpentine belt tensioner; above it is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same.

We're just going to put our old one back in because it works fine. Just feed your serpentine belt tensioner back down into place with one bolt at the top already in. Then, once you get it lined up, just tighten that bolt in by hand, and then replace the other two bolts and tighten them all up. Then torque each of these to 25 foot-pounds.

Now you want to follow this belt diagram as you're putting the belt back on. You can reference it again throughout the process. Mike's also going to explain the easiest way to put the belt back. First step for putting the belt on is to make a sharp bend in your new belt. You want to feed that between your tensioner pulley and the idler pulley and go down that way. Need to help it along a little bit here. As that loop goes down, reach down, and this is your AC compressor down here. Put the loop down and around your AC compressor. Now, I'm going to take a loop and loop it down. It's going over the tensioner pulley, but I'm going down and around the crank pulley. Then hopefully you can see on the crank pulley, make sure it gets onto the crank pulley. Then a little tight up and around the water pump pulley here. Then there's an idler pulley, and your power steering pump pulley. I'll leave it off of the alternator for right now. Loop it around the power steering pump pulley over here, around this idler pulley.

Take my pipe, pull as far as I can on the tensioner. I should be able to lift the belt up. I'm going to try and take it off of this idler pulley, get it up onto the alternator, pull my tensioner, and then push the belt down. You can see the idler pulley's the last one, so push it right down under. Replace your air intake hose. Reconnect this hose and then tighten up those two hose clamps.

Hi, I'm Mike Green. I'm one of the owners of 1AAuto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20+ 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 install correctly. That's going to save you time and money. Thank you and enjoy the video.

In this video we're going to be replacing the serpentine belt tensioner on this 1997 Ford expedition. This procedure is the same for any Expedition, Excursion, F150, Navigator, even Blackwood; as long as you've got a 4.6L, 5.4L, or even the V10, this is the same. The tools you'll need are 8 mm 5/16 wrench to disconnect your battery, a 1/2-inch ratchet bar, and a bigger wrench to help you get your belt, and then a 10 mm socket and ratchet to remove the bolts. That size could change by vehicle but probably not.

What you want to is disconnect your negative battery cable. On these trucks it's either a this is a standard 5/16, or 8 mm's also work.

Okay, so you're obviously going to have to remove your serpentine belt. The belt tensioner has a 1/2-inch square hole in it, so basically what I'm showing you here is that's a 1/2-inch drive handle that is in the tensioner, so basically you want to take a 1/2-inch drive socket handle and get it into the tensioner. Now I'm going to take a large wrench and actually get it on that handle, which gives me more leverage, and then you pull up on the wrench, and then I'm going to fast motion here. Once you pull the wrench aside, you can pull the belt right off of the alternator. Then you basically you don't have to pull it all the way off, probably get the tensioner out, but you have to pull it at least partway out.

Your serpentine belt tensioner is right here. It attaches with three bolts: one there, one right down there, and one here. Those are 10 mm bolts. Okay, a little fast forward through the kind of monotonous stuff. Don't try to work this fast at home. Goes to here. I've got my wrench on this last one, not a lot of room to get my hand down in there to push. I'm having a lot of trouble with it, so I'm going to do here put this block of wood down in there to contact the wrench, and then use a little old-school impact here. Got it, loosen it up. Okay, and again, after that little tip, we'll go through a little fast forward. And again, do not try and duplicate my lightning-fast hands there.

The tensioner fell off and fell down, and so, there is the tensioner out of the vehicle. Obviously, our tensioners will not be exactly the same. This tensioner is fine, so I'm actually just going to mount it right back on the vehicle, which is going to be fun. The tensioner mounts in this way with the pulley facing in. So what I'm going to do is I'm going to get it down in there, and them I'm going to get this first bolt in, the easiest one to reach. So I feed it down, and I get my hand under here to support the tensioner, manage to the tensioner in place, get that first bolt in. One in place, and then the hardest one will be this right down here. I got all three bolts in place. I'll hand tighten them, and then I'll tighten them up.

Okay, we're going to some fast motion so you won't have to watch all this boring junk. I'm just using a little bit of air ratchet there, a little bit, and then tightening it with my hand.

Once those are tight, then you're ready to put your serpentine belt back on. When you're ready to put your serpentine belt back on, you definitely want to find this diagram right here. This is your routine diagram, and it's really going to be difficult for me to video putting the belt on; so I'm going to kind of show you what the best practice is.

What you want to do is curl your belt up and feed a loop down through here, and then put that loop around the AC compression. Then the same thing: take it, make a loop, feed it down in here to put around your crank, and then feed a loop down here to your power steering pump. Then make sure it's up and over your water pump, and then you basically should be able to pull your belt up, and then you put your handle back into the tensioner here, pull this way on the tensioner, and you should be able to pull up and onto the alternator.

Once you got your belt on, reattach your battery, and start up the car. Listen. Make sure there's no screeching or grinding or anything, and if it's all nice and quiet, then your belt's on there correctly.

We hope this helps you out.

In this video, we're going to show you how to replace the serpentine belt tensioner on this 2003 Ford F250 Super Duty with the 5.4 liter engine. This process is pretty much the same for the 5.4 liter as well as the 6.8 liter, although the 6.8 liter has a little less clearance to get in there. Tools you'll need are a ½ inch drive breaker bar or a ratchet handle with pipe and you'll see how I use that when I reinstall the belt. You'll also need a 10mm socket with a ratchet extension or a 10mm wrench will work. In addition you'll need a stool and you'll hear some squeaking in the background a lot in this video and that's the stool slipping underneath me as I'm leaning over the hood of the truck.

Very important: find your belt routing diagram. On this truck, it's on the driver's side, right near the radiator. It looks like this. This is a very important piece of information. This help helps you get the belt routed correctly. It can be somewhat confusing if you don't have a diagram. If this has been painted over or is missing, I would actually draw a diagram just by hand, just so you have it. It helps.

Here is your tensioner right here, take a ½ inch ratchet, insert it there. Now force your ratchet clockwise to loosen the belt, and then take if off the alternator. Push down on the ratchet, grab the belt and slowly let your tensioner back, and pull the belt off. It goes down around your compresser here. Your tensioner is held on by three bolts: here, here and here, all 10mm. So I don't bore you, I'm going to hit the fast forward button as I remove those three 10mm bolts just using a regular socket and ratchet. The bolts usually come out pretty easy. Loosen them up a few turns and then they'll turn by hand. For the last one, you may have to reach down there with your other hand and hold up the tensioner some while you remove the last bolt.

The new tensioner from 1A Auto is the exact same as the old one. I'm going to put a bolt into it. Put it down in. Start that first bolt. Just fast forward again. Just like when you take it out, you start these bolts in and they'll pretty much thread in by hand. After you thread them in by hand, then, we'll tighten them up. Now tighten these up to about 25 foot pounds or good and tight with a small ratchet like this. Everything is aluminum so you don't want to over tighten it.

Take your new belt from 1A Auto and you want to make a nice tight loop and you're going to stuff it down in between where your tensioner and idler are. You're going to then reach underneath, grab that loop, and pull it through. I know you can't really see this, but I'm just pulling it through and then putting it around my A/C compressor pulley. Keep a loop down and around the crankshaft. After you're around the crankshaft, come up and ignore the alternator pulley for right now and put it down around your power steering pulley way over here. What you do is put a little loop between your bypass pulley and tensioner, get that down around the A/C, then put your loop around the crankshaft, then pull the loop up and around the power steering pulley and then you're on everything except the alternator. Closer up, you can see the belt is way down around the A/C compressor, around the tensioner there, and around the water pump and then down around the power steering pump over here. I can pull it up some. You can see I've got my ratchet in there. Take a piece of pipe; it's going to give me extra leverage to make this job really easy. Before I pull on that, I'm going to pull by belt up and make sure to feel down around the a/c pulley and the crank pulley and the power steering pulley. Everything feels like it's on there correctly. Bring my ratchet up, use the pipe, take the tension off, put the belt on and then slowly . I don't like the way it's looking on my tensioner here. I'm just going to pull it up a little bit. Slowly release that. Take the pipe off and take the ratchet off.

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 tensioner on this 2003 Mercury Mountaineer with the 4.6-liter V8 engine. It's the same part and similar process on most of the Ford, Lincoln, and Mercury trucks that have this same engine. The items that you'll need for this include a new serpentine belt tensioner from 1AAuto.com, 1/2 inch socket bar or ratchet and pipe, long screwdriver, 10mm socket and ratchet, and a torque wrench.

The easiest way to get to your tensioner is from underneath. It's right up here, you just take a 1/2 inch ratchet and push it into that square hole on your tensioner. Using a pipe for extra leverage, it makes this a lot easier. You just pull back, release the tension on the belt, and you can pull it free from this pulley. Then when you release the tension on the ratchet, you actually have to take the fan and make sure it doesn't get caught on the wrong side of the handle. Pull it out like that and then pull your ratchet out.

Now I'm going to reach down, and pull the belt off of the pulley where we already loosened it up, and then you can pull this up and out. You've just got to be careful not to get it caught on the fan too much. I'm going to reach way down on this side and I'm going to put my hand in there like that. I can feel the belt and I can pull it up off the pulley that's down here which is if you look on the diagram, I'm pulling it off of this pulley here and while I'm pulling it off of that pulley, I'm going to pull up on the belt because you have to basically pull it right in between this space here. I'm just guiding it up through there. Now the only place it's on here is the big crank pulley. Again, I'm just reaching down and I just have a hold of the belt right here, I'm pulling it out away from the engine to try and get it off of the crank pulley. If I can reach down in here I could pull it out from the crank pulley, pull it out from the water pump, and then just pull the whole thing right up and out.

Now you want to remove these three 10mm bolts on your serpentine belt tensioner. We'll fast-forward as Mike does this. You may realize that we've disconnected that radiator hose, but you don't need to do that, that was just for shooting purposes. Once you remove those bolts, you can just pull that tensioner up and out.

Up top is the old serpentine belt tensioner; below it is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same.

Take your new serpentine belt tensioner and feed it down into place. You want to find a gap in the fan blades, some of the gaps are slightly larger in between each blade. You want to find one of the larger gaps, feed the tensioner down in, and then once you've got it somewhat lined up start feeding the bolts in and just get them started, each one by hand. We'll just fast-forward as Mike tightens all those up. Now torque all three of those to 30 foot-pounds.

To reinstall your new belt, what you want to do is put a loop down around the crank first and get it lined up on your water pump. then you basically have to kind of jam a loop right down in between your tensioner, down to this pulley, and then you can line everything else up. First, we'll take it and we'll put the loop down between the fan and the water pump pulley for the crank. It's almost like you're lassoing the crank a little bit. You reach way down in there and grab the belt with your other hand and flip it around the crank. Going underneath this pulley here, you can see the belt right there. I just got to get it pushed on the crank and guide it with my hand and pull it up and around. It's on the crank. The back side that comes up, the belt that comes up from this side of the crank. You got to push in and push it around your water pump pulley and push this loop, you push this loop down onto that side for right now. We're not going to worry about it too much. The harder part is taking this part of the belt right here. Once you have it down and around the crank and pull it up.

Then you just want to take. You probably can't see my fingers, but I'm just pushing it between the idler pulley and the pulley underneath. Just take a long screwdriver and push it right down through there. Now if you want to reach up from the bottom, grab that belt, pull it through, and put it down around your A/C compressor here. Now from up here, I'm just going to pull that tight around that A/C compressor pulley. I'm reaching down with this hand and making sure it's on there correctly. Then I'll put this, this has to go down now around this idler pulley, and push it down, and it's somewhat ready to go around these two pulleys here. Basically, I've got my belt, I've put it first down around the crank pulley, and then I went down around the A/C pulley. Now it's on the alternator, it's underneath this idler pulley, and when I pull my tensioner, I'll put it around these two pulleys the rest of the way.

A quick check and see it's on the crank correctly. It's really not on this A/C pulley correctly, so I'm going to lightly pull on it and get it on around there correctly. After I do that I'm going to reach up in here and pull on the belt a little more, that will tighten it up. I'm going to use a flexible bar and basically, what you want to try and do is slide the bar up in there and just try to feed it in. You'll have to push out against the fan as you're feeding this in and get it to go into the tensioner. You want to have it at just a little bit of an angle, not straight up and down, angle it, feed it up in, and you really have to push back against the fan and force the part in there. Get on there and now I can pull that as far as I can. Reach up on this side, put the belt on, make sure the belt is on the power steering pulley.

From down here, we've got the belt on there correctly. It's on my crank pulley correctly and it's on this one correctly. This is the one that I fed it onto right here. I'll take the wrench off and, again, you have to push back against the fan some. Actually my fan's caught. I'm going to pull it. Make sure you feed the fan underneath and out. Now from the topside, you can see it's on the alternator correctly and it's on these idler pulleys and the water pump correctly.
