In this clip we're going to talk about the proper way to remove and replace the EGR valve or exhaust gas recirculation valve on a 1997 Ford F-150. In this step we're going to talk about the proper method for locating your engines EGR valve. The EGR valve is going to be located under the hood as you can see I have it open here. I know just from experience that this is the EGR valve. It's the little space ship looking device, and the reason why it's round and flat is because it has a diaphragm in it. It also has a control solenoid so what we're looking for is this vacuum line. You can see it's green and it runs over here to the control solenoid. There's actually two components to this, if you take a look underneath your hood there's going to be an array of stickers. You can see all these on here, this is specific engine information. And what I want to point out to you is that on this schematic you can see it has the label EGR right there. And it has that green vacuum line on for it. What I want you to do to locate your EGR valve is first refer to this sticker, locate the component that says EGR solenoid, find the vacuum line on it that goes to EGR valve and determine what color it is. Right there you can see that it's green so you know it's on the top of the engine. This is going to be on the driver's side and this is going to be on the driver's side in the rear of the engine. So what you do is you go from here, you locate the green vacuum line in the front of the driver's side of the engine which is here. You follow it through its conduit, there's green again, all the way up to the top and green again. That's going to indicate the location of your EGR valve. That's the proper way to read your vacuum line schematic and find the valve.
