Hi I'm Mike Green. I'm one of the owners at 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 1AAuto.com. The right parts installed correctly, that's going to save you time and money. Thank you and enjoy the video.
First you want to disconnect your negative battery cable, you probably need to use an 8mm wrench to loosen it. Okay, so right here is your idler pulley and then right down and bellow is your belt tensioner. What you want to do is take a 15mm wrench and put it on to that belt tensioner and then you're going to push it clockwise to loosen the tension on the belt. What I'm doing is I'm using a larger wrench to hook onto that 15mm wrench and give it some more leverage.
Now I'm going to pull that idler pulley over and as I push you might be able to see the tension give on the belt and then I flip the belt right off of the idler pulley. Now I can pull the belt up and out and the wrenches up and out. Now you're going to want to remove your idler pulley to allow you easier access to the belt tensioner, so that's just a 15mm bolt and then again I use the larger wrench on there for some extra leverage. I'll speed it up. You just pull that 15mm bolt right out of there. Now I'm going to do the rest of this by hand and then pull the idler pulley up and out. Now with the idler pulley removed you can see that your tensioner's right down there and that's a T47 Torx screw. You'll need a T47 screw bit to get in there and I'm just going to fast forward taking that off, because it's kind of boring just turning your wrench. And then you'll see it comes right up and out.
You can see here on the left is the new one and on the right is the original. Now, the new one has a little different look to it, but it's going to fit and function the same, just need to swap the bolt over and then we're ready to install it back in the engine. Now you're going to with the bolt in it lower it down into place and there is a pin on the back of it that keeps it from turning and you basically mount it a little bit further counterclockwise than you think you should and get the bolt going and then that pin will hit up against the engine block as you turn it clockwise. I'm going to fast forward through this, because you really can't see what I'm doing, all is I'm doing is putting it down in there and getting that bolt going and then making sure that I push it against the engine block, and make sure that it hits the stop on that pin when you turn it clockwise.
Now when you tighten up this bolt you want to get it pretty tight, probably about 35 to 40 foot pounds and here they are. Now we can reinstall our idler pulley and it's a good idea to replace these both at the same time. If you want to see just the idler pulley we do have a video for just that part, and then I'll speed it up a little bit and then we'll put the belt back on.
Now I'm going to put the serpentine belt back on. Here's a diagram of how it goes on this three liter with A/C. Right now I'm working it down onto the belt tensioner around the water pump and the belt tensioner and then I'm going to have it up and I'm actually going to work it down underneath the idler pulley. Now I have a loop that goes up next to the alternator in my left hand there and I'm going to put my 15mm wrench on my tensioner and then I'm using the larger wrench, I'm going to hook it on there for more leverage. Then as I pull on the tensioner to release tension on the belt, I'll pull the belt up and onto the alternator. Release the tensioner and the belts are all pretty much routed. I'm just going to look down in there and check and make sure that everything is on correctly. Now running the engine it's nice and quiet, no more squealing, squeaking or screeching.
