In this video, we're going to show you how to replace the serpentine belt on this 2006 Chevy Malibu the with 3.5 liter, same as any of this era Malibu with a 3.5 liter. Tools you'll need are: a flat bade screwdriver, 10 and 15 millimeter sockets with ratchet, T25 torx driver, a 3/8 drive ratchet handle, and possibly a piece of pipe for some extra leverage.

You want to remove your intake tube. Use a flat blade screwdriver to loosen this clamp here. Pull out this tube, carefully and with 10mm socket with a ratchet or wrench, remove this bolt here. Then, over here use a T25 torx driver and remove the two screws that hold the top of your air box down. Ease it out of place. Pull your air box and just kind of bring it up. Underneath, you'll see right here, is a little tab, a safety tab, pull that out and press this tab here, and disconnect that. 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. Doing those two bolts now allows you to pull your air box up and out.

Now, we want a 3/8 inch drive, the long ratchet. 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. So, I've got my ratchet down in there and I've got a piece of pipe; it gives me extra leverage. Move that tensioner, kind of, counter clockwise, takes the tension off the belt. Slip the belt right off of my idler pulley there, let that come back, nice and easy. We're going to remove these two 15mm bolts. And again, we'll just, kind of, hit fast forward a little bit as we're removing those two bolts. We'll move that bracket out of the way. Now, before you take that belt off, here's the diagram right there, just make sure you're familiar with what the diagram tells you as far as how it's routed so you that you can be sure to put it on correctly next time. Then you pull the belt off of the alternator up here and then reach way down and ease it off of the crank and the belt is out.

Here, we have our new belt. What I'm going to do is take a loop and put it way down underneath the crank and way down underneath the A/C pulley. This loop comes up from the crank and goes onto the idler pulley. Then we can run this across to our tensioner. Then up to our alternator, it goes right here to this idler pulley here, down around the water pump. Just make sure it's on the A/C compressor. Now we're basically all routed, with the exception of this idler pulley here. We just want to make sure it's down, correctly in the grooves of all these pulleys. It looks like it's off one groove here on the A/C pulley. It looks good. To reinstall, put my wrench down and make sure it's secure, pull it up as far as I can, pull my belt and put it right around that idler and slowly let go of my wrench. It should be all installed and looking good. We're going to 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, probably about 35 to 40 foot pounds.

Then 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 set it in, making sure your A/C line is out of the way a little bit. Make sure it pushes forward and down. The 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. Plug in the sensor and remember this little safety plug. Turn it over and put that in place. Put our duct down. Make sure it's on the engine correctly all the way. To hook up on your air filter side here, make sure it's tilted way down and then there's three, kind of, 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. Make sure we tighten up our intake clamp here.
