Hi I am Mike Green. I am one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I am 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.

In this video we are going to show you how to replace the serpentine belt idler pulley on this 2001 Ford Taurus with a 3.0L. The only tools you will need are a 15mm wrench and a little bit larger wrench for leverage and also an 8mm wrench to unhook your battery.

The squeaking noise is a bad idler pulley; pretty common symptom. First you want to disconnect your negative battery cable. You will probably need to use an 8mm wrench to loosen it. Right here is your idler pulley and right down and below is your belt tensioner. What you want to do is take a 15mm wrench and put it on to that belt tensioner. You are going to push it clockwise to loosen the tension on the belt. What I am doing is using a larger wrench to hook on to that 15mm wrench to give it some more leverage. I am going to pull that idler pulley over and as I push you might be able to see the tension give on the belt and I flip the belt right off the idler pulley. I can pull the belt up and out and the wrenches up and out.

Put your 15mm wrench on there. Now I am going to do the rest of this by hand and then pull the idler pulley up and out. You can see there, and what I am going to do is take that washer and I am going to remove that washer so that I can take the bolt out of the pulley. Here we've got the new pulley with the bolt in it, down and in; belt out of there, bolt started.

Now I am going to put the serpentine belt back on. Here is a diagram of how it goes on, on this 3.0L with AC. Right now I am working it down onto the belt tensioner, around the water pump and the belt tensioner, and then I am going to have it up and I am 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. I am going to put my 15mm wrench on my tensioner. I am using the larger wrench; I am going to hook it on there for more leverage. As I pull on the tensioner to release tension on the belt, I will pull the belt up and on to the alternator.

Release the tensioner and the belts all pretty much routed. I am just doing check, look down in there and check and make sure that everything is on correctly. Now running the engine it is nice and quiet. No more squealing, squeaking, or screeching.
