If you remove the banjo bolt for the rack-to-cooling-coil hose, you'll drain the reservoir and the coil, but there will still be fluid in the U-shaped pump-to-rack hose, the reservoir-to-pump hose, and the rack itself. You could remove both banjo bolts and drain the system through both hoses, then turn the steering wheel from lock to lock several times to force the fluid out of the rack. Make sure to have replacement crush washers on hand for both banjo bolts - they have different thread diameters.

A siphon pump drains the fluid from the reservoir with less mess than a turkey baster.

Phamine, before you buy the tool, you might want to try what this guy is suggesting. Sounds like it worked for him. Looks like he is referring to something like this:

Hey Starless, Great write up!
Although Starless is kind enough to let us barrow his tools (BMW5346) I just used two pairs of channel locks to remove the hoses from the cooling coil. Had them off in no time! But it's great that people share tools on this site. Who knows..... Ya just might need it some day.

Tackling this in the next couple weekends. Alex, I did you find this hose to leak as well:

Number 3:


Here at Autohauz #32416750156
Power Steering Hose; Power Steering Pump to Steering Rack

I am replacing all the hoses as well as this one. I took a look under my car and sure enough there was some a good of ATF saturated on it. I will try to snap some pics.

Do you have any idea it this sucker is pretty straight forward to take out?

Thanks.

That's the pressure hose from the pump to the rack. It's easy to remove and replace. Be prepared to catch plenty of fluid from the pump outlet and the rack when you disconnect the hose ends.

Make sure to get new crush washers for the banjo bolt connection at the rack. Torque to the value found in the Bentley manual.

There is also a little green O-ring for the fitting that connects to the pump. The threaded fitting does not necessarily bottom out on the pump body; the O-ring is what makes the seal. Use a flare nut wrench on this fitting.

If you are changing from the LF-20 pump to the LF-30 pump, the pressure hose is not the same for each. Make sure you get the hose that's particular to the pump.

Burdell,

Does this green 0-ring come with the new hoses or is it another item I will need to add to my basket. I am not seeing it anywhere listed at Autohaus, would you by any chance have the p/n or a link to Realoem on which part it is? Thanks for the help! Really sucks a special tool is needed to remove one of the lines though. $30 for a little piece of aluminum, dam.

I think the O-ring is part number 4 on the RealOEM diagram you posted earlier. The new hose I bought at the dealer did not include the O-ring.

The $30 AST tool for the quick release couplings is well worth the price for the convenience it offers. Plus, they're good people over at AST.

Another great Starless DIY!

I did all four hoses + reservoir today. Went surprisingly well, and I managed not get everything soaked in ATF. I had a leaky pressure hose and decided to replace the other three while I had the system open. Bought the AST tool for the connections to the cooling loop, and it worked like a champ.

If you do the pressure hose, you'll also need a 19mm socket for its banjo bolt at the rack end, and IIRC, a 17mm flare nut wrench on the pump end, as G. P. Burdell mentioned. This was for the hose for an LF-20 pump, YMMV with an LF-30 hose.

The bracket/isolator assembly at the end of the loop in the Codan pressure hose (okay, so I wanted to save a few $$$) was a little different than my old hose, but it fit okay after finagling the angle of the connection to the pump.

I was able to get at the hoses without the removal tool but its was quite frustrating and took a bit of tinkering. The bottom one gave me the most difficulty. I got it loose using two vice grips, or you could try some adjustable pliers.

As far as I remember just a socket wrench. But I do recall the space was tight there.

In addition to the Amazon link genuity posted, you can also call AST and place an order directly. They're very friendly people.

Same here. No special tools required.
