Help! Power Steering Failed Today....Fluid not low but very dirty...

As the title says, my power steering stopped working, the fluid was at the correct level but very dirty, it was dark and brown, not clean and red,, i siphoned off what was in the resevoir and replaced with fresh, not enough i guess because p/s still didn't. Do i just need to drain and replace with fresh fluid or has a pump stopped working ?! any way to test a pump?! Any ideas ? Thanks..

Yeah, if it stopped working you're going to need to do more than replace the fluid.

To totally get it all out though you'll need to do the siphoning exercise you mentioned about five or six times. Each time refill and run the car for 3 mins, and then repeat. That way you'll get all the gunk out.

Stop with the fluid. Too late.
More than likely your pump quit. Remove the drive belt and spin the PS pulley.
If it spins with no resistance or the shaft just pulls out of the pump, guess what!

Read the label on the pump if you must replace to get the correct model.

Empty your reservoir half way,if you don't see the fluid circulation in the reservoir you probably will need a new power steering pump. I bought a 330ci and the power steering was gone so i ordered a Meley pump, our e46 need the F20 pump. You can get the F30 which is more of a heavy duty one but you will need an extra hose for the connection because its not entirely compatible even though it will fit and work, the high pressure hose is a bit different. That being said,buy a new reservoir as well because it holds a filter inside and if you said the fluid was dirty. . .not a good idea to keep the same one. If you havent upgraded to a metal pulley purchase one because th original one is made out of plastic. Im not sure if we can use universal power steering fluid i need to figure that out before i do the switch. Ill let you know how mine went hopefully this was helpful.

WARNING-----PS does not take PS fluid. Takes ATF fluid. Says so on the cap.

the pump fluid has been badly neglected. Need to flush out your whole system when replacing the pump. Fluid should be changed frequently to keep it fresh. Helps keep the hoses healthy too.

Make life easy; replace the pump with the same model rather than trying to adapt the other model.

Mine is brown-red, and not transparent, since a few days when I turn my car engine on it makes an insane KRRGGRRGRRGG sound, the floor under the pedals shakes. After I turn the wheel a few inches the sound and shaking stops and everything goes back to normal. Since that has happened for the first time, the steering wheel feels much lighter :S I checked the power steering tank labeled ATF at the front rightof the engine and it's pretty full but brown red non transparent. Any ideas? The power steering is still on as the steering doesn't feel heavy and even lighter than before.

Maybe you can save things.
Do the fluid flush, including replacing the reservori/filter.
There are DIY's around for this.

Must work until fluid in reservoir looks like new out of bottle. Mine still does on my 96K miles car with all original equipment.

Thanks for the advice guys, will certainly be tested the pump impeller, car is 140k miles, and the ps system has been neglected... The system is not leaking at least, and i'll be flushing it and replacing the reservoir and pump with the same one so no need to buy those different hoses...! Dextron 3 is the right stuff for us i believe... Onto ebay!

Yes, Dexron III is correct.

And Dexron VI (six) is backward compatible.

DIY is short for do-it-yourself
plenty of them showing how to flush PS fluid along with reservoir replacement.

It is, but that's really for transmissions. It's a bit lower viscosity, so for the PS pump maybe stick with Dexron III (Dex/Mercon). Dexron VI will definitely be okay though. I wonder if it would make the steering feel a bit lighter.

Quite possibly. I think I'll give it a try next PS fluid change. Will let y'all know in about a year.

OK, then I'll throw in a prediction.
I bet minor differences in viscosity will make no difference. The steering effort is more a function of the hydraulic pressure that the pump is set to deliver than the free flow rate of the fluid used in there. The pump force will easily overshadow the viscosity.
