Part #: YLE500390 Replace / Install Alternator Demonstrated On Range Rover Sport Supercharged
Hi I'm Doug, your tech support representative here at Atlantic British. And in this video we're going to talk about alternators. Now something that I've seen come up on a pretty regular basis lately on some of the Sports and the LR3s is a failure of the alternator. Actually a failure of the diode in the alternator. And some of the most common systems of what I'm getting on the phone calls is an intermittent lighting of the battery warning light on the dashboard, and a sudden increase in the noise from the cooling fan. And essentially what happens is when the diode goes it induces an AC current into the system that the body control module basically interprets as energize the front fan. And so it will sound louder than you will normally hear it. So those are 2 of the symptoms that are starting to show up on a pretty regular basis. A lot of these vehicles are getting older. They're hitting the high miles. These alternators have seen 130 150 some of them 190,000 miles and it's starting to affect them. So what we're going to do is we're going to show you how to install an alternator on this from underneath. I know in the service manual the installation is a little more involved. We have some tricks to show you that will help you speed that up. And there's something else to look for while you're working in that general area. So let's get started. All right, so, right off the bat the first thing we want to do is disconnect the negative lead off the battery. Before I do that, and before you even get started, I did want to show you a tool that you're going to need to be able to release the belt tension you got to take off in order to be able to access to alternator. And this is similar, there are other models out there, but it's similar design, basically just a long thin bar with a 12 point cut out on the end of it. They'll come with different sockets for the sizes. You'll need a 15 mm on this. This particular application is going to basically apply to both the Sport and the LR3. Same design as the 4.4 engine. And then on some vehicles, and we may find we need to do it on this, there's essentially a plate that adapts to different angles on this and then is held in place by a bolt. That will give you an access angle that will get up to the tensioner to slip the belt off. We're not going to take the belt off completely. All we need to do is get it off the alternator. All right, we're going to start with disconnecting the negative lead off the battery. You have 2 tabs in the front that hold this cover down. Pop that out of the way. Simply pull that out. Negative lead is going to be the one closest to the back of the vehicle. It's a 13 mm. You can do it with a pair of pliers if you want. You just need to loosen that a turn or 2.
As you can see you have 1 up there. You have the idler in the back. And on the power steering pump. And on the AC compressor. That all looks really good. So, we release the tension. Pop all this out. Make sure you get your tool out of that tensioner. Most times as I say I pop it out and sure enough it leaves that little extension in there. Always check that. Make sure you don't leave any under the hood. So essentially at this point your alternator is in. And all we're going to do now is put back the side cover that has the 4 plastic rivets, the front panel here. And the splash pan. And what I probably suggest you do at this point before you go putting all that back on, drop it down and start it up and make sure everything is working right and also make sure, put a volt meter across the battery. Make sure that unit is charging. But you should be good at this point. And this should take care of both that intermittent battery light and that noisy front fan. So when you're ready to install the alternator on your Sport or LR3, and I will say that the LR3 and Sport without the Supercharger is a little bit easier because there isn't so much plumbing in the way, just give a call to any of our knowledgeable salesmen at 1-800-533-2210. And thanks for watching.
