Those clamps on the power steering hoses are crap. No wonder they leak. Managed to replace the clamps (.89c each) and a hose ($6.56 vs $180 dealer part!) in about an hour and half.
I just got my power steering hoses replaced and the bill reached $500.00!!! thats not the worst part of it, I drove my car this morning and I was damn near out of power steering fluid!! WTF I pay $500.00 for my shit to continue leaking I say this place is out... I'm taking it back tomarrow

Yup. I got an estimate of about $450 and I said no way I can fix it myself. I went to a supply shop where I bought the hose (same size but way overkill if you note the 300psi rating) and the clamps all for under 10 bucks! The dealers price for the hose parts is exhorbitant.
If you notice the stock part has the hose and metal coils permanently attached, I cut away the permanent clamp connecting these two pieces and used my own hose and clamp. The metal coils are least likely to fail and it doesn't make sense replacing this piece. I have no idea why BMW made this part one unit rather than allowing you to replace the hose alone (like what I've done).
It's a relief our cars are so easy to work on.
What may have happened to you is they filled the PS reservoir but didn't crank the steering wheel full left to right to get the new fluid in the system. To do it right add fluid, crank the wheel full right to left, then add more fluid, crank again and recheck the level.

This is a very common problem with e36's I've seen. Never thought off just replacing the hose though. I was thinking about replacing the metal lines and hose together but the part is still really expensive. Maybe I should give this a shot....what kind of hose did you use? (inner diameter?)
ps at the dealer all the mechanics use those screw clamps to replace the "permanent" ones, theyre just so much easier to work with and reuse
thanks

I really can't remember. The input and output hoses are different diameters. I cut a piece of the hose connected permanently to the coil to a hose supply store and they matched the hose dimensions (though a *much* stronger hose). I used sheet metal cutters to cut the clamp holding the hose to the metal coil and then replaced the hose along with the hose clamps.
It's a lot stronger than the original. As I'd mentioned, it makes no sense to replace the coil if its not broken. And I'm over $400 richer!
I'm pretty sure the reason those two parts are permenately joined is because of the high pressures they can experience. The reason it's metal and rubber is the metal parts and there shape (like some sort of musical instrument) actually function as an oil cooler.
I replaced one of these hoses my self not to long ago, and i believe the cost of the hose was not much over 100.00.
Not bad to save a couple bills
what are the metal coils you are referring to??? Do you mean the hose "ends" that are attached to the actual steering rack??
Funny this topic shoudl come up, because I was doing my oil change last night and I also noticed my PS hose was "seepy" and a little wet looking... I was thinking of just replacing the clamps, but if I can replace the hose as you did, that would be excellent.
Do you have the size of the hose that you did use for this procedure? About what length did you need to complete the job correctly?
Thanks for the help and the picture!

I'll look around for the excess hose if I have any and give you the dimensions. I really don't know exactly since I took the old busted hose to the hose shop and had them give me an equivalent. As far as length, just get it too long and cut it. I didn't measure it.
You can probably get away with replacing the hose clamps beneath the reservoir, but my problem was that the hose broke where it attached to the cooling coil so I had to address that hose to get it fixed.
It's actually a fun little project since you know you're saving yourself a couple hundred an hour to do it.
M3Nut can you give us a detailed description on how to cut the connection between the coil and the hose? and did you ever find the inner diameter of the hose?
Den
bump for more description and reason it took 1:30
Thank you very much.
Sinned: I used a pair of aviation snips, basically heavy duty scissors, to cut the hose and the metal clamp holding the hose to the cooling coils. Unfortunately, I didn't keep the excess hose or the original hose. I ended up having to take a piece of the original hose to a hose supple company and have them match it.
ImageDynamicsM3: It took 1 1/2 hours with most of that time twisting and tearing off all the POS BMW pinch clamps. This effort not onlly saved me over $400, but you'll see the hose I used is extreme overkill. The hoses were "sweating" oil before one finally burst, now they're dry as a bone.
this is very good solution compared to expensive dealer work.
Can you give more information on what kind-brand name of hose you purchased at the store, is it available at auto stores?
You are confident that it is stronger than original one but did you ask how it will perform under high temp ?
Thanks in advance,
Mark

M3C: It's not likely available at the autostore, or even if they did have it would I trust them to know exactly what was necessary. I looked up a few hose (hydraulic) supply companies from the yellow pages. When I went to the hydraulics company I gave them my hose and we went through a half dozen different adequate hoses of the correct size. Of course I opted for the most robust/heavy duty solution. They told me the hose was overkill. They were very familiar with the requirements of a powersteering supply hose. It helped I had a sample (the original) with me.
now i understand...hydraulics company.
Thank you for valuable and simple solution info.
Mark
M3Nut,
Do you happen to have the brand and part number of the hose you used? If not, the ID/OD? I'd like to do this mod, but don't want to have to leave my car appart when I go find a hose.
Thanks,
Chris
Gvl: Sorry I wish I could help you. My hose burst so I had the option, and little choice, to take that broken hose to the supply company. I'll dig around the garage later today and post the specs if I can find the scrap pieces, but definitely I will read the markings next time the car is lifted.
OEM hoses aren't TOO bad at bimmerparts.com -

If I'm reading the hose right, it says 1/2 INCH right before the 300psi. Is anybody else seeing that?
Seems about the right size.
My PS hoses just started leaking at ~80k miles, so this sounds like an excellent solution to an inherently flawed design.
Who is interested in a Power Steering Fix Kit...Im thinking about putting together the correct hoses with a lil more slack than the factory hose, so that it doesnt loosen, with necessary clamps(they are reinforced and have extra inner steel that wont puncture your hoses) and the correct pressure limits for the job, I have access to all the hoses and clamps and can get a kit together even with the correct fluid needed to fill the power steering reservoir after the fix...Im going to try to find a metal cutter so that the clamp can be cut off...
so the kit will include,
1. Correct Hose
2. 2 Reinforced Clamps
3. Power Steering Fluid
4. Metal Cutter (possibly)
5. Detailed Instructions (via email or hard copy)
Shipped Around $30-35 bucks...(way cheaper than $75 dollar part from BMW for the clamped coils with hose)
Let me know if you guys are interested,

okay okay... brb I'll lift the car and see what I can find...
I hate to burst your bubble but it will still leak but not from the hoses.
There is a vent in the reservoir cap at the end of one of the finger grips...take the cap of and look at it. That's why the reservoir stays wet.
Also I would at least flare the metal cooling line before clamping the hose. I believe the reservoir has a flare molded into the plastic nipples to prevent the hoses from poping off under pressure.

and it includes the cooling duct and HAS THE PRESSURE DROP ORFICE IN THE RUBBER HOSE which is a designed restriction in the system to reduce pressure before it gets back to the resevior! Just replacing the hose will result in the designed pressure drop being lost.
