Hi, I'm Don 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 on this 2001 Ford Escort ZX2 with the dual overhead cam engine. It's a little involved but not that complicated of a project. You will need a 10 millimeter socket and ratchet, as well as a 13 millimeter socket and ratchet.

The first thing you're going to want, before you do this repair, is a belt diagram. We have a nice one made up for you right here. It should give you a pretty good representation of how the belt is routed. Starting with the top left, that's the alternator. Then going to the right, that's an idler pulley. That goes to the power steering pump, then down to the A/C compressor, then over to the crankshaft, then to the tensioner pulley, then to the water pump, another idler pulley and up to the alternator.

In the lower front and right front wheel area, there's seven 10 millimeter bolts that hold the splash pan in place. In this case in our car there's only four and you're going to remove all of them. Actually what we find is we take off one, and the pan bends down and we try to remove the other ones, but the clips in behind were so rusted that we decided we didn't want to break all them, so we just left it that way and just let the pan or the splash guard hang down out of the way. I've got a 13 millimeter socket on the end of my ratchet and I'm going to put it on the bolt that goes through the pulley, the tensioner pulley, and I'm going to turn it clockwise to remove the pressure on the belt, and then slide the belt off the crank, and the rest of the pulleys. Now the rest of the way, it's a matter of just pulling it down, twisting it a little bit to get it off some of the pulleys. Then you could also pull it off from the top as well.

You're not really going to be able to see me doing the belt, but sneak it back in, follow the diagram for routing it. That first step that Don just did was, he just got the belt down, down below the A/C and the crank pulley preliminarily. What Don just did there was that there's just some clearance issues getting by the water pump and those tensioner pulleys, so he just twisted it at the side and got it over on its way to the alternator. The top part it's pretty much done. It's around the alternator, underneath the idler and over the power steering. Now, I want to get this belt on the other side of this pulley, the ribbed pulley here, so I'm going to twist it and try not to have it fall off the alternator pulley, which is right above it. All right, good. Now what we've done here is we pulled a loop across and you can see I'm helping him out a little bit just holding the belt off of the A/C pulley so he can pull the loop from that tensioner on the backside of the motor towards the front and put it onto the tensioner in the front of the engine. In order to get the wrench in there it's better to have the pulley off of the crank rather than the A/C pulley, so he just transfers it, takes it off the crank so he has enough room to get it on.

I'm using a 15 millimeter here, which is what the new one came with and turning it clockwise. I have to release the tension on the bearing and I've got to make sure too that all my belts are on the pulleys, because if they're off a little bit it's not going to give me the room I need. So everything is on except for the crank pulley. As I do this it's going to give me more room. I'm going to hold it tight. You can see Don, is working the wrench with the right hand and then using his left hand to push the belt up onto the crank pulley. Make sure they're all on. Make sure all of them are on and the belt is lined up with the teeth on your pulleys and plug you're A/C back in if you took that off to gain more flexibility getting in there. I'm just going to give it one more look up top and below. I want to make sure the tooth belt is seated correctly on the power steering, alternator, water pump, and below this idler pulley. Once you've done that just put the splash pan back up and bolt it back in place.
