And to start, obviously we’re going to start with the battery removal, or disconnecting the battery at least, to make sure that we don’t have any power surges, power spikes, things like that, because we do have with the valve cover and harness installed, a connection going to each injector, so we’ve actually already removed the valve cover gasket, and we do have a video on how to replace a valve cover gasket if you need instructions on how to do that. • So we’re down to the injector itself, and now we’re going to show you the other steps involved in getting this injector out and putting a new injector back in, as well as all the torque specs that are going to be involved, because you will want to follow the torque specs to the letter on replacing the injectors, so again, our battery is disconnected, we have our cover and valve cover off already, so let’s get into this injector and show you what needs to be done. • With everything on the top out of the way, we’re going to go ahead and need to start removing some components to get to the injector, and to start, we’re going to start with the actual fuel line itself. Now, we have a connection at the fuel rail here for one side of the line, and then we have a connection on the other side of the line that feeds back to the actual feed tube for the injector. Now we’re going to use a 19-millimeter wrench to loosen those up, and once we have them loose, we can just thread those off. • Now, before I pull this line all the way off, one thing I will note, and I’ve already done it on this engine, you want to take some shop air or some brake cleaner, something to just kind of get some of the debris out of the way around the rail and around the actual insert for the feed tube. Any debris that finds its way into that tube, or into that channel for the tube, could find its way into the injector. • This is a common rail injection system, so any small amount of debris can actually get lodged inside of these injectors and cause them to stick wide open, or just fail completely in the beginning. Don’t want to have that happen, so at least try to clean this area out. We’re in a fortunate spot here because this engine is on the stand. I know it sounds a little bit harder when you’re thinking about it in the truck itself, but best-case scenario, if you can just get some shop air to this area, compressed air of some sort, or some way of cleaning out the area, just to make sure we don’t introduce debris into the system. • And so with that said, we’ll go ahead and remove the fuel line. Now we have a retaining nut that’s actually sitting on top and holding down the feed tube going into the portal there for the injector, and what we need to do is we need to get that retaining nut off first, and it’s a pretty tight spot here, so what I’m recommending, and what I’m using, is a short 15 16ths socket, because that’ll fit right in that little spot. It snugs up to the side of the head, so you’re actually going to have room to get an extension in there as well, then you can break that free and have a little bit more room to work. So in the case where you may be working with the engine in the truck, this actually gives you a little bit more flexibility to get an extension in, whether it be a six-inch or three-inch, and work that retaining nut off... • • For full transcript, visit https://www.knowyourparts.com/technic...
