One of the most common oil leaks on an E39 is the Power Steering reservoir lines. When I first saw the leak I though I may have to replace the pump or something more major. But problem ended up being a simple fix of replacing the 2 low pressure lines that come off the Power Steering reservoir.
We partnered with Ryan from E39Source for the video. Make sure you check them out.

Great write up! Love Ryan and his channel...if it wasn't for him and his diys i would have never had the courage to buy and work on my M5

@KeepItDirtyOffRoad 2 года назад

Totally agree. He’s a wealth of knowledge and experience with these cars

It is. It’s just a pain to do

@@KeepItDirtyOffRoad removing the hoses would definitely be the annoying part. It’s always the simple stuff that makes it hours longer 😂

Nice work. Is there a reason you didn't do all the lines? What brand hoses did you go with?

@KeepItDirtyOffRoad 4 года назад

notimeboy high pressure lines require removing the subframe support to access them. Those lines were not leaking so no need to replace them.

Thanks, This is very helpful! I need to replace my hoses too. I ordered an original set, but it didn't came with the O-ring for the nozzle into the cooler (behind the keeper). Do you have the O-ring part number or a description? Also, I am going to follow your recommendation by change both of the nozzle rings. Does both of the nozzles have the same dimentions, so also samen O-ring size? Oh, and how much ATF oil do I need to order after draining the system?

@KeepItDirtyOffRoad 2 года назад

The o ring should be included with the hose. I don’t think you can order separately. As for amount of fluid, I don’t know how much we used. I think Ryan used about half a gallon (2 quarts), but I could be wrong.

@sirmo667 Год назад

Part number for the o ring? Mine didn’t come with one

@cparente7 3 года назад

Nice video thanks! Can you please confirm part number of the hose Ryan called "lowest point" in system, the first hose he removed? Hard to tell the difference between the two hoses on RealOEM diagram. TIA.

@KeepItDirtyOffRoad 3 года назад

Part numbers are in the description. Lowest point is the one to the pump I think.

Just found this vid. I know you did not replace the line from the cooler to the steering box. Mine is leaking. On my car, the flexible section is crimped to the hardline on both ends. On yours, it is crimped to the end closest to the cooler but has a hose clamp on the other end, attaching to the hardline going to the steering box. Can you point me to a part number that would allow me to retrofit this version into my car? It would make future replacement much easier, when the flexible part of the hose goes bad again. Thanks!

@KeepItDirtyOffRoad Год назад

I don’t know all those part number but here is the website I and e39 source uses to find part numbers www.realoem.com

@kwstine1 Год назад

@@KeepItDirtyOffRoad Thanks, I searched RealOEM extensively for anything like I see on your car but only found a complete crimped line for all years of E39 M5. I've contacted Ryan as well and we'll see if he has any input. Thank you though for your reply!

Hi! According to the ETK catalogue the power steering hose (32412228873) is supposed to be connected to the pump using a banjo coupling + washer + rubber seal and a banjo bolt . On this video it seems the hose is just secured with a hose clamp right onto the pump nozzle? Is this because of difference in year models of the M5 or could it be that the previous owner of this car has somehow taken a shortcut and not been using these parts?

@KeepItDirtyOffRoad 4 года назад

Torqen V I actually asked about this. For this year (03) the hose came with crimp connectors for both hoses. These have to be replaced every few years so having a hose clamp works out much better.
