Video: Power Steering Pump Replacement On Discovery Series II
Watch Doug, our Land Rover Master Technician, show you how to access and replace the power steering pump on a 1999-2004 Discovery Series II . The power steering pump, which is part # QVB500080OE is a common replacement item, and it is recommended that the hoses related to this installation be replaced too. Power Steering Hose Kit # 9397D2 , includes the pump to box, reservoir to pump, and low pressure hoses. Doug also covers the power steering reservoir (QFX100371) discussing issues that develop over time with this item. You will also need the ACE and Power Steering Fluid. Doug shows the genuine fluid STC50519 in the video. There is also now an excellent aftermarket alternative for this fluid now from Rock Oil that we recommend (and will save you a few $$.)
Kit # QVB500080OE Installing Power Steering Pump & Hoses and Fluid on Discovery Series II, 1999-2004, 8-Cylinder Gasoline, North American SpecificationsHi I'm Doug and I'm your tech support representative for Atlantic British, and in this video we are going to touch base on another very common repair, mostly on the Discovery 2s, Discovery 1s, P38s, any of the 4.0 or 4.6 engines, is power steering pump. You'll find that over a period of time there's several reasons why these pumps can fail. You may develop a bad power steering leak which is a wearout of the seal. Could be bearing failure, or an actual internal failure of the impeller or the drive unit internally. All right, so this is the pump that's going to be used on your vehicle. And essentially what you have here is most of your hydraulic system which is the pump, this is the gravity feed line that would run from the reservoir down to the pump, from the pump to the cooler, from the cooler to the power steering box, and then from the box back up to the reservoir. Now what happens is these can fail internally, you could have a leaky seal, or you can have a bearing failure. If it's an internal or a bearing failure I would generally recommend not only do you replace the hoses, you're going to take a good look at them when you take the system apart, but inside the reservoir, and I don't know how well you're going to see it on the video, but straight down inside you actually have a filter built into these reservoirs. If you have a pump failure or a hose failure, and these hoses can wear internally, they're just strictly rubber hoses. That material will build up on that filter. And that's basically there to keep those contaminants from going through the system. Eventually that filter can get plugged up to the point where you won't get sufficient flow from the reservoir down to the pump and create a whining, or an erratic steering. So if you've got 100,000 miles on it and you're replacing the pump due to a failure, or you've had a hose collapse internally, you want to get that reservoir as well. Make sure you have a good clean filter in there and it will help the system operate. And also importantly is the fluid that's used in the system. This is fluid supplied and made by Land Rover called Active Corner Enhancement Power Steering Fluid, or short ACE Fluid. And what will happen is if you use regular power steering fluid or Dexron 3 in these pumps, over a period of time it will cause internal damage. They're not made to be used with that fluid. This is the fluid that is specially formulated for the system, that can make a world of difference on how long it last you after you do a replacement. So what we're going to do now is going to show you how access and replace the pump, how to access the hoses and then do some visual inspections to give you an idea if you should be replacing other components as well. You'll see some bubbling in the top fluid, because we know we definitely pushed some air through there. Now we're just going to let it sit for about 15 or 20 minutes, let that air bleed out of the system, And then you can cap it off. And you should be ready to go. What I suggest is take it for a test drive. When you get home shut it off. Let it sit for a few minutes. And then double check your height. You may use a little bit more fluid. You may need to add just a little bit to get it to the full line. As of that, you've replaced your power steering pump, saved yourself a lot of money and ready to go for another 100,000 miles. So, when you're ready to change over your power steering pump or any of your hoses, just call any of our knowledgeable salesman at 1-800-533-2210. Thanks for watching.
