Changing power steering fluid? - Page 2 - PeachParts Mercedes-Benz Forum

If you use a large drain pan and drop the hose all the way down near the pan it will not be messy at all.

Good luck,

What about turning the steering wheel a little, stoping, turning a little, stopping and so on?

Or what about turning the steering wheel very slowly?

The fluid comes out fast even with the wheels stationary because the pump is working. It simply comes out faster when wheels are on the ground from (I imagine) the backpressure. It's required to turn the wheel full motion from lock to lock to flush the fluid from all areas of the system. There's little benefit to turning the wheel just a little at a time. Your helper shouldn't have to race through this exercise with the steering wheel, just have him turn it normally.

The hose does not come off easily. Any suggestion?

The hose lost its elasticity at the metal clip area. That area stays compressed even after removing the metal clip.

I used a screw driver and I used a piece of cloth to blunt the end and used it to pry the hose loose.

what kind of pwr steering fluid can I use to use to flush my system? Is it ok to use any pwr steering fluid at my local pep boys? Then I just use MB pwr sttering fluid to fill it up? Can I use the pwr sttering flush I find in the stores?

Regular ole power steering fluid works fine, i've always just flushed it with power steering fluid, im not sure what power steering flush you're talkin about.

i have seen something or like a bottle of pwr steering flush fluid some time ago. Not sure if it still sells now. I was planning to just get the cheap pwr steering fluid for the flush and use the good stuff when filling up

Oh, so it is safe to use regular power steering fluid in a Mercedes system? If that is the case, I am assuming that "Dextron" transmission fluid is safe to use? I know that on American cars that a lot the manufacturers suggest transmission fluid for the power steering pumps.

My power steering fluid level is 1/2 way down and my pump will "growl" when it is cold (until it warms up), so I know I need fluid right away.

Thanks if someone can confirm this.

I've heard that transmission fluid harms the seals of the power steering fluid pump, this would also include the dextron stuff.

My car also started to develop a noise from the power steering pump when cold, I replaced the power steering filter and the fluid, now there's no noise and seems fine. I used power steering fluid from Wal-Mart and got the filter from an import auto store. In order to most of the fluid out I used a turkey baster and ran the engine at the same time. It's a very quick and easy task.

Don't use ATF in the power steering system.

If you want to be extra kind to your system, use the Mercedes power steering fluid.

It is excellent to change the power steering pump filter, I always use the Mercedes one.

I have never had to change a power steering pump except once in 14 cars. It was the one that ran ATF in it and started to leak like a pig. The filter looked like it had never been changed.

Where is the filter?

It should be at the bottom of the reservoir.

Well I noticed that if I park my MB with the front of the car uphill, then it will drip a couple of drips of PS fluid, but I have not investigated yet to see where it was coming from. When I park it level, it does not leak a drop of oil. Obviously it has been leaking for a while, because today I noticed that the PO had left two 1/2 bottles of PS fluid in the luggage compartment. One was "Tech" brand (Wal-Mart) and the other was "Snap" (PennZoil/QuakerState). I went ahead and used a little of that to bring it back the "full" line. It was not low at all. Actually, it was at the same level it was a month ago. He must have parked the car at an incline often. I am hoping it is just a loose hose. I will check those connections soon.
