How To Replace Serpentine Belt 2000-04 Ford Focus

Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the internet. Hi. I'm Mike with 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 remove and re-install a serpentine belt on this 2003 Ford Focus. This has the 2L dual overhead cam V-tech engine. It is pretty easy. The tools you need are jack and jackstands because you do have to access it from down below, 10mm socket with a ratchet and extension and a 15mm wrench as well as a pipe for some extra leverage. I do use lights in the video, so probably a flashlight additionally would help as well.

Here's a good tool here. This is the belt diagram. This will help you get the belt back together. I'll show this again later when we're about to put the belt on. In the passenger side of the engine compartment, there's a 10mm bolt right here. Use a wrench socket and extension. If you look back in here, you'll see a little clip. What I'll do is get a screw driver down here and pry out on the water bottle a little bit. Lift it up and then off. Pull this out of the clip and remove your water bottle out of the way and then right here is your power steering reservoir. Lift that up and move it out of the way as well. When you look out from underneath, you'll find two bolts that hold this cover on. They're 10mm as well.

Now I'll just fast-forward here as I remove those two 10mm bolts. If you look right up in here, this is your belt tensioner. Put a 15mm wrench on there. I like to use a nice big piece of pipe. It helps to get some extra leverage, okay. As you go clockwise on that, it actually loosens up the belt and you can pull the belt off of you're AC compressor down here. Slowly let your wrench go. Now, I just removed your belt off your lower pulley so you could pull it up from the top. Now, from up here, take the pulley off your power steering pump and then the alternator and I just take and pull the belt out in front here, you've got to reach down, make sure it comes in front of your tensioner pulley.

Basically what I'm doing here is just reaching down and twist the belt and pull it between the front of the pulleys and the body of the car. It's ready to come out. We have the belt off and pretty soon here, I'm going to get to put the belt back on, but again here's a look at the diagram. This will help you a lot as you try and get the belt back on correctly. To re-install your belt and you can see, I am putting the old belt on there. It's still in good shape. One of the reasons I took it off, you can see I've got a nice new alternator on there. Check out the other videos to see that, but take a loop and go from the front. We're going to stick this loop underneath this engine mount.

You'll have to pull a little bit with your finger here somehow. I'm almost getting through, okay and you put that loop on the alternator there. Take the belt and feed it down between the body and your tensioner pulley and then I'll force this down between the body and your water-pump pulley. You pretty much just force the belt right down. It should be on top of your power steering pulley here, okay so from the top, you can see we've got the belt pretty much forced down. We've got it on top of our alternator here and we've got it on top of our power steering pump here and below this idler pulley.
The belt comes down and you take this loop and need to twist it and force it up and onto the water pump. Then this loop comes down. You have to by-pass your AC compressor right now and put that into the crank. Pull it as tight as you can. Take these 15mm wrench again. Put your pipe on there. Loosen that tensioner and you pull your belt down make sure it's on there. Let it go, and we see one little problem here. Its not clipped on my crank correctly. I'm just going to fast-forward here, and of course I don't do a good job of filming it but just check your pulley.

I noticed that it's not, it's one groove off from the crank, so I loosen it back up, take it off the AC compressor pulley and get it on to the crank pulley correctly and check all the rest of the pulleys. Make sure it's on there right and then put it back on again. I think it's confirmed belt's on the alternator well and on the power steering pump correctly. I'm going to continue to fast forward as I put that dust and rock shield back in place and use the two bolts. Bolt it back in place and you can see I'm their tools now just to kind of get it done quickly. I'll just continue through fast-forward as I put that power steering reservoir back in place. It just pressed into place with the rubber grommets and then put the coolant reservoir back in place and put the 10mm bolt in place to hold it.
