In this video, we will show you how to change your serpentine belt tensioner. If your belt is squeaking, sometimes it can be because this tensioner has gone bad. It's not holding enough tension against your belt. This is on a 2001 Malibu. It should be the same as any '97 to '03 Malibu with the 3.1 liter engine. Tools you'll need are a jack or engine hoist, 15mm and 18mm sockets with ratchets and extension, and then you need a 3/8 drive. You either need a flexible bar or the ratchet handle.
Your serpentine belt is obviously right here on the passenger side of your engine. What you actually need to do, is remove this engine mount which involves removing two 18mm bolts here, and then two 15mm nuts, one there and one down there. That is the engine mount, so you either need to support here with an engine crane, or you need to use a jack and support underneath the oil pan here. Do not jack the car up yet. You actually just want to support the weight of the engine. Spray some penetrating oil on those studs down lower. I cheat a little bit and use a 15mm socket, with an impact wrench. There's no reason you can't reach everything pretty easily with just a regular ratchet and extension. Now, I've got my 18mm socket on here. I'm going to loosen up one of these bolts. I'm going to start loosening the other bolt. You're going to see the engine falling which is actually more the car rising. What you want to do now is take your jack. Jack the engine up. Now, it's supporting the engine. You can remove these bolts the rest of the way. This mount, slide it back right out.
I'm just going to remove these two lines just to make it easier for you to see. What you want to do, is take your jack. Jack the engine up a little bit extra. Right down in here is your tensioner. What I have is a little flex arm. What you want to do with this flex arm is put it down. Here is a 3/8 inch hole at the bottom of the tensioner. You want to put it in just like that. You see right here is my bar. I'm going to reach in, and pull the bar up which pulls on the tensioner and releases the tension on the belt. You can pull the belt off, and slowly release your bar back down. Be careful not to pinch your fingers. Take the bar out, and then just take your belt off above with this.
Here's your alternator. Your tensioner is right down here, 15mm socket. It just comes up and out. I'm going to take that bolt out.
Here's the original tensioner, and a new tensioner from 1A Auto. You see it's all the same. It has the little marking to hold it in the right spot. Put the bolt through. Put it down in. Start the bolt first. Make sure that that detent holds it. Tighten up the bolt.
Here is your belt routing diagram. This is key. Make sure you have this before you take the belt off. If you don't have this, make sure you draw yourself a diagram similar, so you can get the belt on again. It's hard to film this, so you just have to take my word that I'm doing what I say I'm doing. Take your belt. You want to put a loop down underneath the crankshaft which is the lowest largest pulley, and in the A/C compressor which is the pulley that's lowest and closest to the front of the vehicle. It comes up under this power steering pulley right up over here. I'm going to reach down, and pull it, and point it back to this idler pulley here, and then around under the tensioner pulley. I can pull it up on top of my alternator right here. Now, I'm all routed except for the idler pulley. I'm going take my 3/8 bar, put it down in to my tensioner. I need both hands. Pull the bar up. Grab on my belt here, and slip it under that idler pulley, then let my tensioner go. I got a couple off a little bit here. Just check, make sure your belt is on correctly everywhere. It doesn't look like it's quite on my crank pulley correctly. Pull up again on the tensioner. Reach down. Flip it a little bit. Now, it's on there correctly. It appears to be on everywhere correctly.
We're just going to speed through putting this stuff back in. Put the mount back down in there. You can let your engine down just a little bit. Start the two top bolts on the mount. Preliminarily tighten them up. You can let the engine all the way down. Take the jack out. Start your 15mm nuts on top. Preliminarily tighten them as well. Here, I'm just reconnecting those hoses that I moved out of your way. Now, use a wrench. Make sure that the mount bolts are tight, but not too tight.

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 2008 Chevy Equinox. The process is basically the same for any Equinox or Torrent of this vintage with the 3.4-liter V6. If your tensioner is going bad, you'll notice some squeaking when you turn on accessories such as your air conditioning. Mostly when your air conditioning compressor comes on you'll hear some squeaking because the belt is not tight enough. The tools you'll need are a flat blade screwdriver; 10mm, 15mm and 18mm sockets with ratchets and extensions; a 3/8 drive ratchet or flex handle.
To get to it you do have remove the intake tube, not too difficult. There's a plug here. You just take a little tab move it to the side, pull that off, and then there are two clamps to loosen. Okay, I'm going to speed this up a little bit. What I found actually is you only need to loosen up the clamp that's on the engine side, or closer to the engine, and then you pull the tube off the engine.
Now there are a couple of clips you just pull off with your thumbs. You can lift this up to get your air box up and off. There's a little safety clamp here that you'll want to remove carefully, and then you can disconnect this harness, pull this right out, and your 10mm bolt right back here, remove that. Probably take your air cleaner out, now your air box will come right up. Pull it back. There is a harness right here, just pull that. Now take your air box out.
You'll want to put a jack right underneath the engine. Now with the air box out of the way, you want to basically unbolt your engine mount, and it's 18mm bolts on the outside and then the inner ones are 15mm. Before you undo the inner ones, you want to just jack up your engine a little bit enough so that you see that mount start moving up, and then you can remove the three 15mm bolts.
In this next part it's a little difficult to see what I'm doing, so I kind of drew an arrow. The arrow points to your belt tensioner, and you can see down at the bottom if you're looking at it in good enough resolution that the tensioner has a small 3/8 square hole in it, so you take a 3/8 drive flex handle. If you jack up the engine enough you can probably get a regular ratchet handle on there and you put it into that square hole and you'll see what you do with it.
Okay, now here's your tensioner, and you're going to need kind of some flexible handle like this. Basically you just want to put the handle in, flex that into the tensioner, and then push it in. Then you're going to pull up on your handle. Okay, let the tension off the belt to get the belt off. Slowly let your handle back down. In the next shot you may notice that the belt is gone, that you do not have to remove your belt to replace the belt tensioner. If you do remove your belt, I have a belt tensioner diagram that you'll see later in the video. Let's remove the belt tensioner with a 15mm socket and ratchet which will remove the bolt here.
Okay, we're going down here and looking at that surface where it mounts. You can see there's a little hole right here. I'm going to make sure with our new tensioner that this little tab goes right into that hole. Bolt it in, and you kind of look down into that tab go in and start our bolt in. Okay, just fast-forward as I put the bolt in, and then use my 15mm ratchet and socket, tighten it up. Tighten it to about 25 to 30 foot-pounds. You don't want to go too tight because it is going into aluminum and you could strip the threads.
Next up we're going to put the belt back on. I am going to pick it up just from having the belt preliminarily routed. Here is a diagram to help you route it if you either took your belt off or if it fell off a couple pulleys and you weren't sure how to get it back on. Put your bar in and pull up on your tensioner. Put your bolt down onto this idler pulley. Make sure your alternator won't off. Let your tensioner go. With your engine jacked up high enough you can get that right out.
Put your belt back on and start the bolts. Okay, you can let your engine down some. Make sure you get the bolts started first. Okay, speed it up here some. I'll start those bolts in. Just make sure the jack is positioned so that the engine is just barely lifting up on that mount and preliminarily tighten those bolts and those are 15mm bolts. Then let the engine down some, put on the 18mm nuts, and then preliminarily tighten them. Then I'm going to tighten the 18mm nuts to 85 foot-pounds and then I'm going to tighten the 15mm bolts to 45 foot-pounds.
Now I'll put my air box down in and my wiring harnesses go up above. Now there's two kind of rubber plugs that go in the holes in the front. Slide them in place and push them forward. Tighten up that bolt nice and firm, and then make sure you put the pin for the wiring harness back in place. Put the air cleaner back in. Make sure it's seated correctly and it does have a little tab here so it goes in the right way. I'm going to put the outside of the air box in first and make sure the harnesses don't get in your way. Down in place, pop that one back on, pop that one back on, make sure that's all back. Tighten up. Be sure to reconnect that hose and that right here and this little lock inserts from the back.

In this video, we're going to show you how to replace a serpentine belt tensioner on this 2006 Chevy Malibu. Your serpentine belt tensioner might be going bad if notice that your belt's a little bit loose, or maybe your alternator squeaks a little bit. Tools you'll need for this repair are flat blade screwdriver, 10 and 15mm sockets with a ratchet, T25 Torx driver, 3/8 inch drive ratchet handle and piece of pipe for some extra leverage.
You're going to want to remove your intake tube. Use a flat blade screwdriver to loosen this clamp here. Pull out this tube, carefully. Use a 10mm socket with a ratchet or wrench and remove this bolt here. Then, over here, use a T25 Torx driver and remove the two screws that hold the top of air box down. Take this out of place. Just pull your tube off and you bring it here. Underneath, you can see, right here, there's a little tab, a little safety tab, pull that out and then press this tab here, disconnect that and take your intake tube off.
Now, we're going to remove two 10mm bolts, one here and one back here. Hit the fast forward button here as I just remove those two bolts and those are 10mm bolts. Removing those two bolts, now, allows you to pull your air box up and out. Now we want a 3/8 inch drive long ratchet and we're going to take the ratchet and here's our tensioner and down at the bottom of the tensioner is a 3/8 inch square hole. I've got my ratchet down in there and I got a piece of pipe. It gives me extra leverage. Move that tensioner counterclockwise. It takes the tension off the belt. Slip the belt right off my idler pulley there, and let that come back nice and easy.
Now, to change my tensioner, it's just a 15mm bolt right here. Use a little fast forward as I remove that bolt. Your tensioner comes up and out.
Here's our old tensioner and a new tensioner from 1A Auto. There are just minor cosmetic differences. It's going to bolt in there exactly the same. Take the bolts out of our old one, and put our new one in there. There is a little nub here and there's actually a hole right here around one-o'-clock. Jjust put your bolt in, make sure you get that nice and flush, and just tighten the bolt in. Speed it up here as we start that bolt and then start tightening it up with our wrench. Tighten it up to about 35 foot-pounds.
At this point, you're ready to put the belt back on. If you wanted to replace your belt, you can just check out our other videos and there's a couple extra steps that you do have to do, as you can see we did augment our tensioner with a new belt but if you don't replace your belt it should just be in the same place, basically, all routed, other than under the idler pulley that's just above the tensioner. To reinstall, put my wrench right down in and make sure it's secure. Pull it up as far as I can and take my belt put it right around that idler, slowly let go of my wrench, and we should be all installed and looking good. Speed up. Make sure you put that damper back on with the two 15mm bolts. Put those in and tighten them up nice and firm, to probably about 35 to 40 foot-pounds.
Now, you're going to want to put your air box back in place. There's two round rubber nubs that go in the two holes in the front here. Tilt it down, get those to take place, and then you have to move your A/C line out of the way a little bit, and make sure it pushes forward and down and a long bolt goes into the back. We'll speed it up here as we tighten up those bolts and get that air box in place.
Bring our air duct back over and plug in the sensor. Now, remember this little safety plug. You just want to turn it over and put that in place. Put our duct down and make sure it's on the engine correctly and all the way. To hook up on your air filter side here, make sure it's tilted way down and then there are three teeth that go in. Make sure it goes on correctly. We'll speed it up here as we put those two T25 Torx screws in place and then the bolt for the air duct near the radiator. Actually, pull this rubber grommet off the hose, put it into the intake first and push the hose down into it, and make sure we tighten up our intake clamp here.
