I trusted the auto parts guy. I asked "are you sure this is for my BMW". He assured me it was. Obviously, he was wrong; hence, I should not have listened to him.

There's not much here about power steering fluids (PSF); mostly it seems people go with:
- Mobile 1
- Any Dexron III ATF

Based, at least, on these sporadic PSF ATF threads:
What type of ATF to use for PSF?
Dexron II for older BMW PSF
Dexron II or Dexron III for PSF in 3-series

UPDATE: I did call Red Line and spoke to technical support who told me they'd recommend Red Line D4 ATF (which was supposed to meet the Dexron IV proposed specification but GM skipped to a later number but the D4 moniker stuck). When asked about the difference between Dexron II and Dexron III, they said it wasn't a big chemical change ... mostly it was two things, (a) anti-wear chemistry and (b) constant-over-time slipperiness (mostly for use in manual transmissions with low-offset gears).

Strangely, they don't recommend their PSF for manufacturers (such as BMW) who recommend ATF as PSF even though their PSF container (and spec sheet included above) clearly says it meets the Dexron specifications; they told me, quite nicely, that theiir PSF and ATF oils are definitely different.

What I'll do is buy a few quarts of Red Line D4 ATF and do a quickie ad hoc power steering flush DIY

This is pretty much what I did when I flushed my PSF.

Yup, ATF only. The outside of the reservoir will get mucky, no matter....the reason is there is a vent in the cap. You can replace the o-ring on the cap, but it will make little difference. I even installed a new reservoir, and then was explained about the vent, and that it is normal. So don't get to "anal" about it.

Yeah ... the only "solution" to the psf muck from the cap venting I saw was on the utube video previously alluded to.

I love the shampoo bottle idea!

Muuuch better than my coke bottle and turkey baster approach (on my ATE brake fluid flush).

PS: But ooooh. The towel shows much nicer than ... um .... than ... those whites!

Bad news. It's hard to describe noises but upon subsequent inspection, the noise doesn't seem to be coming from the (now full) steering fluid pump. It's "down there" somewhere.

It's subtle ... but discernible.

I think I need to research those mechanics' stethoscopes ... as I don't own that in my tool repertoire. Depending on cost and usefulness, I generally don't mind purchasing the tools I need ...

Need to dig for recommended debugging tools for hard-to-find noises in the engine bay ...

I don't have a video camera but I can borrow one. I'll see if I can do that to get a clip of the noise ... but it's subtle ... amongst the ambient engine noise ...

To prevent the power steering cap from leaking your new Dexron III ATF fluid, apparently replacing the O-ring works better than an M5 gym sock.

Thanks bluebee,

I just did exactly this: replacing the PS Reservoir O-ring and the outside of the PS Reservoir is nice and clean.

+1 on having crud on power steering reservoir. Next fix is new hoses and replace any old rubber O-rings.

I did think for a while it was the power steering; but now I'm not so sure since I've replaced it with Dexron II (by mistake); and now twice with Dexron VI (which is compatible with Dexron III).

I bought new belts and twice replaced the power steering fluid with Dexron VI ATF ... and the cold-start squeal seems to be vastly diminished ... but still there.

So I bought a mechanic's stethoscope to see if I can further pinpoint the noise.

I've never used one of these, so, it will be interesting to make sure I don't get wrapped up in it like spaghetti!

I just now ran into this thread again, while researching links for a newbie when I realized I broke a cardinal rule ... which is to follow up on any thread that I start (as a common courtesy to all that tried to help).

Sorry for that faux pas ... Here's an update by way of thanks for your help!

The "noise" I had upon cold startup was finally "cured" six months later when I replaced ALL the drive system components which was "forced" upon me when the alternator suddenly failed on me (leaving me stranded in the middle of the road on a hill, rolling backward to find a safe place to park it to wait for the tow, much to my embarrassment and chagrin).

In hind sight, I should never have waited six months for something to break to finally figure out what was wrong, but, I have a pig-headed way of not replacing things until I can positively diagnose that they are indeed bad.

As requested in this thread, I posted a video clip of the noise here ...

As suggested in this thread, I replaced all the drive system components:
- the alternator (the pulley, when spun by hand, had a clicking sound)
- the idler roller (which was very dry and barely spun by hand)
- both mechanical tensioners (both of which seemed dry when spun by hand)
- both belts (the upper serpentine belt was cracked in zillions of places so it was long overdue for replacement)

And, as suggested in this thread, I had previously replaced the o-ring in the power steering reservoir cap so no leakage was coming from there, but, while I had the power steering reservoir bracket unbolted, I performed the cn90 retrofit fix of the leaking power steering hose on the bottom.

I think that's it by way of update. I did have a series of mishaps ... but we won't embarrass me further by delving into that, will we!

- Specific question: How to get the viscous fan clutch nut on straight (it's crooked)
- Specific Question: How do you safely remove the upper radiator hose with u-pins?
-WANTED: An ingenious method of removing radiator nipple
- What is the most likely cause of this oil leak above the lower radiator hose?
- How to make your own BMW special cooling system & drive belt counterhold tools
etc.

And then ... a couple of months after the belt-drive system overhaul ... the cooling system blew up!

Luckily, I had a complete set of cooling system replacement parts from OemBimmerparts in my garage ... lying in wait!

In case anyone needs to know what power steering fluid to use, what coolant, what brake fluid, etc., see the VERY best of E39 Links:

Another method (old school) is to use a long-handled screwdriver - set the tip of the screwdriver where you want to listen, and cover the handle end with your thumb, and put you ear on your thumb.

You can hear bearings/bushings going bad or just isolate sounds to a specific area. HTH
