Changing/flushing power steering fluid

I checked the fluid in the reservoir a few days later and it still looked brand new, hinting at the fact that I replaced the entire volume.

All you are doing is diluting the old fluid with new fluid so by the time you're done, most of the fluid in the system is new. This does not completely remove the old fluid from the system.

Next time will pour it into a container, then into the reservoir.

This link shows the fine print on the containers for CH11S and CH202. Both says they are compatible and can be mixed with the other.

What are the part numbers for the crush washers. Getbmwparts doesn't know and the local dealership isn't sure!

[VictorH]

I don't have the part numbers but I can tell you what the dealer provided as the replacement is slightly different size than what's on the car.

I've done the power steering fluid replacement twice now and have re-used the old washers both times with no leaks or trouble. As long you are reasonable with the tightness you should be fine (i.e. don't over-tighten).

Does anyone know the washer part numbers?

[jagman]

My brother in law flushed my power steering fluid but we cannot get it to stop leaking at the banjo bolt. Is there a recommended torque setting for tightening the bolt? This happens whether we use the new or old crush washers. Does anyone have a recommended technique? I'm just asking because the obvious isn't working .

Personally, I just stick with the baster method. It's quick and easy.

I just flushed my fluid and used lucas oils power steering fluid due to the fact that it has over a 100 degree higher flash point than the factory fluid ! Which I boiled at burnt at the track. The fluid is also available at pep boys for 8 dollars for 32oz.

I am about to do this baster method. How many times do you guys do it?

Until the fluid out of the baster started looking like fresh fluid from the bottle.

So my method:
- Suck old fluid out
- Pour new fluid in
- Start car and do lock to lock about 3-4 times
- Repeat

I went through about half a bottle of fluid before it looked clean.

Thanks Sounds easy and effective.

Just make sure you are careful because there's a little screen at the bottom. Don't go jamming that baster in there

[AP3X_FTW]

Nobody has the part numbers for the two crush washers for the top banjo bolt?

[pbonsalb]

Look them up on realoem

[squartus]

Yea I just use the baster method and do it every other oil change, fluid stays nice and new. Its prob overkill but its easy and the fluid is not much.

[pbonsalb]

There is a ps cooler so the simple drain or turkey baster method gets only what is in the reservoir.

[gatorfast]

Think I will try the turkey basted method. Is one can of fluid enough?

[squartus]

Yea the first time you do it a can is enouf, empty all out of the reservior refill turn steering wheel few times empty refill again until fluid is a nice pristine green.
I even took car on a nice spirited drive for the first time then did one final fluid swap when I got back.

[W Cole]

With the known problem of power steering fluid boiling over on these cars should we be replacing with a different fluid with a higher boiling point?

Here is the part number for the gasket ring:
