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. In this video, we're going to show you our methodology basically for replacing plug wires. We're doing this on a Ford Ranger, but really this goes for any vehicle where you're replacing the plug wires that run from the coil to the spark plugs. Replacing spark plug wires, this is a 4 liter Ranger, a couple of different options. What I usually like to do is I do them one at a time. I unhook the wire from the coil. The first thing I do is I follow the wires down and then I find things like this. This is a little clip that holds the wires. It's important. You don't want to just rip the wires out of here and break these clips. You want to keep these clips intact because they keep the wires from shorting out on anything. You want to make sure that you use them when you put it back together. Usually these clips, if you just get a little screwdriver in here, pry a little bit, you can pull them out. Once you've found any clips like that, then you can just go to the first wire. Like I said, I just do it one at a time. This wire, I do have another little clip right down here, undo, pull this wire out. When you get down to here to where it connects to the engine, you want to try and twist it. You twist and you pull at the same time. You pull the wire off. Take note of where it's routed. It's routed down in between here. Here I've got my new wires all lined up pretty much by size. This one is probably a little bit ... I'm going to take this medium sized one since it is the middle one and it had to go up to the coil. I'm actually going to switch over this armor because that protects it from heat and from shaping on metal. I've got my new one ready to go in. I want to make sure I feed my new one right down through the same way. Obviously, this is the time to change your spark plug if you want to change the spark plugs as well. Then plug it on at the top, push it on, pop it back in here, this back into this retainer. I'll repeat that for all the wires. Just do them one by one. Like I said, if you're looking to replace the spark plugs, that's a good time to do it while you have them apart. You will run into, on a car like this Ranger, this side. You can see it's pretty ... You can't get to the side of the engine. Really, what they intend for you to do is get to the plugs through the inner fender here. Let's see if we can see. You can see there's one of the plugs right here. That's one of the plugs right there. That's one of the plug wires. You can actually reach through down here. That's the best way to get to. You can see that big metal tube right there. That's the exhaust manifold. You obviously want to be doing this when the car is cooled down. You don't want to do it when the car is hot. We hope this helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393.
