That clip on the resivoir is the most properly cursed engineering choice I have seen in a while, I was enjoying myself until I got to that clip. Now I need a beer
Thanks for this awesome video! I have replaced several reservoirs on the W163s but now have a W164 needing the o-ring replaced and thought I'd look online first to see if there were any differences - same process with a different reservoir. You explained EVERYTHING exceptionally well, couldn't have done it better! I appreciate when someone takes the time to explain the details. Many thumbs up!
You would think that through all the years they would design something that doesn't break so often. They perpetuate the same flawed designs. Had a Nissan Armada and a w163. Nissan just required oil changes and nothing else to 100 K. w163 had a significant amount of repairs and maintenance almost every 6 months to do. I guess ML design their cars so their mechanics have something to do all the time.
Awesome. Really appreciated the extra attention you gave to the connections on the rear. Helpful to know what I am dealing when I cannot see it very well.
Super helpful video, thank you for taking the time to create and share it for us DIY folks. In my case, I had a local European automotive repair shop that I have been using for many years repair a leaking reservoir and within a very short period of time the leak had resurfaced. I dealt with the leak for a few years and the leak got progressively worse. Frustrated by this I decided to dig into it myself and I just completed the repair this afternoon. As I was buying replacement seals I was curious about the significant price difference between the URO brand and a genuine Mercedes Benz 000 466 1880 OEM seal so I bought BOTH. Once I removed the faulty one I cleaned it up and took some measurements of it, and both replacements, with my precision calipers. The results were surprising. The measurement I took was of the thickness of the seal rubber. In other words, I wanted to know, once installed, how much the seal would add in terms of diameter. The URO seal was noticeably shinier appearance and it measured in at 2.70mm. The genuine MB seal measured 2.77mm and the worn one that was removed measured just 2.22mm. The ridge that is present on the new seals was clearly compressed on the old one. I also observed something that I felt was a crucial distinction between the genuine MB seal and the others. The MB seal has three tiny nubs on one side of the seal. The old leaky one did not have this, nor did the URO seal. I decided to install the genuine part in this case. Generally speaking I am open to high quality parts from other brands but this is a case where I’d recommend spending the few extra bucks for the MB brand. In any event, I would not have been able to complete the job without your video. Thanks again!
FANTASTIC video. Really appreciate the effort you went to on making this most informative video. Very educational and you have helped me out tremendously. Appreciate you. Many thanks from New Zealand. 20/10.
Really wish I watched this video before I ended up cracking the plastic taking mine out. Not even the videos from FCP Euro was this thorough explaining how to remove and reinstall it. Thank you!
I always enjoy these videos. I had to remove this reservoir to swap a cam adjuster magnet. Your video of the intake manifold swap was great as well, although that was a much more time consuming job!!!
This video very helpful and I applaud the effort... However, I purchased the O-ring from Amazon as advertised by this video and it started leaking after just 2 days. I went to my local Mercedes dealership and purchased one from them. It was only about $3.50 plus tax from the Mercedes dealer. When I compared the Mercedes O-ring to the Amazon one, I did notice that it was more durable. Hope this helps.
Abe Gallegos glad the video was helpful and thank you for the tip on the part. Sorry you had to go back in. I will try and link to a better part. Thank you for watching!
Yesterday prior to reading these comments I installed the URO 1880 seal. Today I bought a new URO seal and a OEM Mercedes one and tried to compare them. The Mercedes one does have the three very tiny evenly spaced dimples. They’re difficult to measure because they’re rubber but I’d say they are almost identical in dimensions although they do look different. If my URO one leaks I’ll install the Mercedes one.
That little “C” clip is very hard to get back on BUT it can be done. Remove the small rubber hose from the reservoir before trying to get the clip back on. If you don’t you will have very limited access and you risk breaking the hose nipple off of the reservoir. On a ‘06 ML 350 the clip is never visible…taking it on and off is all by feel…a mirror helps a little. Before trying to put it back on I tied a long piece of dental floss to it so I wouldn’t lose it in the process. Excellent vid!
The aftermarket seal I bought at the local parts store so I installed it. We’ll see how it does. I wished I had read these comments before doing the job and I would have bought the MB one.
How did you bleed the system after you installed the new pump. Everyone says something different.. Should the car be on the ground and turned off when you cycle the wheels back and forth?
Great video…. I may have to do the same on my 2008 GL 320. FYI I had a power steering leak that was leaking on the rack bushing which eventually rotted out and the car was making clunking sounds every time the steering wheel was turned 😕
You can do an old school flush by filling the res w/ new fluid, turn on car & turn wheel lock to lock, turn car off, pump out fluid, refill and repeat til it's clean. Then there's the other more thorough method: disconnect return line and feed it to a bucket, plug the spot on the res where return line connects, (so fluid doesn't drip out), jack up front end, turn ignition on (don't start car), and turn wheel lock to lock while constantly pouring in new fluid as old stuff is flushed out, not letting the level get too low. 2 ppl make that method easy. Leave enough spare fluid to drain res again in order to reconnect the return line, or try and be slick and get that hose on before you make a mess!
Great video. I went and replaced the filter housing thinking the leaking was there only since the car was burning few ounces of oil. Than I checked the power steering fluid there I realized I have a leak there too. Thank you again. You got a new member.
hi Brian thanks. mi car ml350 2008 is making a strong noise . it look like the steering wheel pump pulley. i can buy the pulley alone. or i does come all together with the steering wheel pump? thanks a lot..
Javier L If the pump is making noise make sure that there’s no leaks in the system. The pulley itself usually does not make noise it’s usually going to be this pump or it’s leaking causing the pump to meet us.
thank you So much for this video! i look forward to doing this on my car as soon as the o-ring comes (fingers crossed that is the cause of the leak). Two questions for you. 1. i have read that it is important to bleed the air out of the system. You do not seem to do this in the video, is there a special procedure for this? 2. i topped the fluid with fluid i was sold at local shop but its not oem (it was claimed to be oem recomended). is there a way i can empty the current fill completely to reload it with oem stuff i ordered when i do the repair? thank you again for such a great video!!!
Pyotr Bagration there's no special trip to bleeding power steering on this car. Just fill it up and let it idle for a few minutes double checking the fluid level then after a couple minutes you can turn the wheel from lock to lock and that's pretty much it. So it would be pretty hard to get all the old fluid out. When you change the reservoir you swap out about 60% of the fluid. There are flushing machines out there but I don't recommend doing those
The power steering fluid from my w164 constantly leaks from the point were the pressure hose and the pump meet despite several attempts to correct this problem. Do you have any useful tips on how to fix this problem once and for all. Thanks.
Have a 2000 55. My steering is very stiff been that way for a while. Its steerable once moving. Its not smooth at all. Anybody has an idea what it can be?
Do you have to drain the fluid if all you are doing is removing to replace the CAM Magnet? or can you just remove the power steering reservoir with the fluid in it?
The C-clip is over-designed. It is easy to push in at assembly line when reservoir and pump are in one piece together, difficult for maintenance. Without it, the 3 threaded bolts at the front will hold the reservoir firmly as this C-clip does.
I replaced my power steering pump and the reservoir also the return line then lifted the front end to get the air out of the rack and it worked perfectly with no problem. Don’t try to get rid of the bubbles with the car on the on the ground. It will not work.
eric chen hi Eric to get the rest of the air cleaner off he'll pull the snorkel on the opposite side off. Then at the very back of the air cleaner or via metal clip your push it towards the firewall. Then you'll grab the air cleaner assembly on the left and right side and pull straight up there's no bolts holding it on. Then to get to the air filters you just flip it over and there's screws on the left and right side that you will remove to get to the actual air filters. I do have a video on my website at www.howtoautomotive.com for Mercedes air filter replacement. You'll just have to search my video page. I'm not near a computer to send you a direct link but if you would like me to in a couple hours I may be able to.
I might as well put my .50 on here too. Whoever the engineer is that designed the E12 bolt to go in the back side of the power steering pump is a real piece of work! Either you need to get with the yeawho that put the aluminum ballon on the A/C line or they need to get you and discuss project completions before you sign your reputation to the document that will make you look stupid for the next 15-20 years! Is 2” to much to ask?
Late on this reply, but I'd say he means mechanics are going to lose their jobs because you do such a great job of explaining these repairs we can all diy now! I definitely appreciate that. (Not that I want mechanics to lose their jobs of course).

Truly one of the most detailed tutorials available for the MERCEDES ML models. Great job!!
Thank you!
Man the level of detail, and explanation, you sir are a God send. Ive been putting this off for months, thinking how hard it would be. thank you!
I wish you luck with the job and thank you for watching!
It's nice to see a video about working on ML350's without a lot of cursing and swearing, finally.
Angry Cat Owner glad you liked the video. Thank you for watching!
Hi Brian. Thanks for the PS reservoir pump o ring fix. Tight script, good camera work and very informative.

Glad the video was helpful. Thank you for watching!
Wonder if you have a video on replacing power steering high pressure hose ? Thanks
Just used this video to guide me on the repair.... excellent instructions!!!

One of the best videos on ML. Thank you.
Only one that shows how to get the c-clip out👍
Thank you for a great DIY ! Question- Don't you need to bleed air from the p/s system?

Personally I find it hard to believe that one of those seals is superior to the other but I will report if I discover differently.
Great job, straightforward explanation, awesome images. Super job from start to finish... Thanks 👍🏼👍🏼
Totally excellent video - thanks!! Do I need to worry about air getting in the system?
Sighclone No the air bleed itself out.
Very helpful, very detailed, great video, thank you so much!
Much appreciated. Really informative and just the right level of details.

cp Lam thank you very much .I'm glad the video helps. If you should ever need any more Mercedes repair videos be sure to subscribe to check those out.
Thank you so much!! Just wondering how much the pump cost
Any chance i could get the power steering system to stop leaking using a “Stop Leak” product
Great video. Good tips and good photography
Thank you! Did everything go smooth for you?
Thank you. You saved me a lot of Trouble. Great job!
This video was a life saver.
Koshon Mitchell glad the video helped. Thank you for watching and writing!
Great video….
I may have to do the same on my 2008 GL 320.
FYI I had a power steering leak that was leaking on the rack bushing which eventually rotted out and the car was making clunking sounds every time the steering wheel was turned 😕
Is their way if getting the old fluid out to start a fresh? Opening a pipe or drain plug? Steering rack

How many bottles of power steering fluid do you need to get to fill it back up?

Where can I find this o-ring? The place I normally buy parts doesn’t seem to know. Great video and tips!
Mrchevyman208 there's links in the description of the video for all the parts.
The power steering fluid from my w164 constantly leaks from the point were the pressure hose and the pump meet despite several attempts to correct this problem.
Do you have any useful tips on how to fix this problem once and for all.
Thanks.
Be enlightened there are two copper washers mounting the hose to the pump change them out.
Thank You. Its a very good and helpful video :)

My book of approved fluids for 2006 ml350 says MB BQ146001 or approved Dexron III atf is recommended. Is this not valid anymore?
D Wall do not put Dexron lll in it! I don’t have the part number or brands in front of me to tell you the exact one but I would check your resources.
This is in the Mercedes book that came with the car, Order No. S-0473-06C (07/05) page 17
Dexron III is recommended for the old recirculating ball systems, which mine is.
D Wall If the fluid that came out of your vehicle was not read do not use the dexron . If the fluid was red then I would say it’s OK
Did it cause a whining noise?
Thanks for the video.
Great video!
Thanks for the valuable informations!!!
Thank you for watching!
Thank you very much .add two wraps of teflon tape under gasket and the silicone you suggested. RUclips is the best
Glad to help. Thank you for watching!
I had my pump and reservoir replaced, but I lose my power steering during turns. What is going on ? The dealership says I need anew coupling.
What happens if you don’t put the C clip back?
Nice walk through & good tips!

Over-designed but under-designed because it’s prone to fail.
what a pain....
Awesome video, but it seems like it would have been easier to just remove the pump and the reservoir together.
Great Video. Thanks!
