No clue how to remove both these lines.
Is that a bolt in the middle?

Yes, it's a bolt. Remove it.

That's on your E39, right?

Yea, E39.

I can't even get my hand down in there.
Do you use a socket or wrench on that bolt?
Oh, take off the airbox.

So, once I remove the bolt, that block will just come off, and unplug the 2 lines?
I will just replace them both, right? Those are both PS lines?

Yes on all questions.

Use a deep socket with a 6" extension and ratchet. I just did my E39 last month. One bolt removal and the block and two hoses just pull right out. Way easier than the E46 with those wicked plastic disconnect fittings.

Both hoses are PS. I would order the whole set of hoses and do them all at once; that helps get most of the old fluid out.

I just did those on a 530i last week, pretty straight forward. E39's blow through power steering hoses super quick for whatever reason. Sure enough the next week the transmission cooler blows out and it's in the shop with a $1200 bill. Glad that's not my car.

Also, any explanation as to why the connections on the bottom of the reservoir appear wet already? They're tight but not over-tight, and the clamps are new OEM. Hoses are Rein CRP.



sure is a sexy car though but I digress



As far as the bolt I went in from the side facing inward with a socket and short extension. Kind of pushing the upper hose up a tad to get the socket in there.

The PS cap has a vent hole and the fluid will slowly make its way down to the hose fittings.

^Great tip Bali. Almost every car I've had the PS reservoir has had some level of film on it. Always bugged me.

orb, that's a stunner of an E39. Love Style 66s. Shame it's not a Sport. Is it yours?

Thanks Bali, makes sense since I kind of overfilled it when re-filling.

And spannerhead it's my fathers. I do whatever little stuff I can such as the lines when home from school. Great car, lots of issues though, probably just due to not being driven much as it's not even at 100k. Drives amazing though, essentially a sport+ now as far as suspension. Just had the suspension upgraded to Koni FSD and Eibach Pro, along with every single piece of hardware down to the dust caps. (see where my OCD comes from).

Sorry for the massive threadjack OP lol

How can you tell it's doesn't have the sport package? I usually tell by the sport seats and 3-spoke steering wheel, but that photo shows neither. Tell me your secrets...

Are you saying the wet PS reservoir is not caused by the cap gasket leaking? My PS reservoir is not overfilled but it's always wet. I just keep wiping it off.

I don't think that's shadow line trim as the side window trim is chrome as opposed to black. It looks just like my non-sport package 2002 530i.

That's what I was saying. orb's dad's 530's window trim is not shadowlined, hence no Sport package.

GREAT TIP, I just replaced my two hoses connected to the reservoir and the reservoir including the cap. I go and check under the hood two days later and there is a small amount of fluid on the reservoir right under the vent hole (not overfilled). I am going to try this today!

Shadowline trim.

Don't be so hard on yourself! No time was wasted. I think your positive contributions to the forum far outweigh any "inconvenience" caused by a misunderstanding.

When you take out the center bolt.
Do both hoses just detach by pulling away?
What is the point of the carved out hooked block?
I need to get an o-ring for both hoses, right?
