In this video I show you how I fixed a 2000 ML320 Mercedes Benz that had a leaking power steering reservoir. Please refer to your shop manual for the proper procedure on fixing your vehicle.

    Great video. What are some signs that you have to change the steering pump as well?

    getting ready to do this on mine after 10 years of great service from my 99 ML430 . this era of Benz pretty easy and straight forward to work on and pretty solid ,now have a second one 04 clk 500.. simple fix

    Ain't nothing wrong with being a sucker and making that money Eric O I think all of us mechanics at some point just don't say no even if we should and we hate working on European vehicles good Work as Always Eric O we all have them stories lol 😆 🤣@SouthMainAutoRepairLLC

    European cars give you a challenge. 🙂 so your day isn't so dull. 😀 (kidding around)

    Very good video, helped me to identify the exact same problem on my ML. Thank you for sharing !

    There is a C clip on the reservoir

    I bought a 2–7 mercedes x164 this past year and I've been pleasantly surprised how easy a lot of the diy work I've been able to do on it has been. There's a lot of really good video tutorials out there.

    John, Before 1992 Mercedes made the best world class cars. Unfortunately after they appointed Mr. Shremp, (Yes it sounds like it looks), he decided that Mercedes AG would become a "mass" producer of cars instead or producing the best engineered cars of the day. As production numbers went up, quality and engineering went out the window. In the long past they required the design engineers to work on the assembly line for a year to instill the idea of building the cars bodies and mechanicals in such a way as to facilitate a non horrendous access to parts needing repair or replacement. As you is plainly evident, the the cars are difficult to work on and the interior trim is of substandard construction.

    Aftermarket parts?

    You should consider doing silent videos with captions. Thanks

    Thank you so much!

    Hi Eric, big fan of your channel – think I've watched just about everyone of your vids! Would be very grateful if you get time to get back to on this question: I've got an ML same as the one in your vid, and the power steering just does not work at all, no noise or kick back or anything, but just no assistance, have checked & topped up the fluid level – no difference, I suspect the pump, but was wondering if there's a way of confirming (with reasonable certainty) before changing? Thanks

    Thanks for the video!I was a little stumped with my job until this video because mine only leaked out overnite with the vehicle off.

  16. Avataaar/Circle Created with python_avatars Tom Hart says:

    Done this on my ML. Got to wonder about the engineers use of plastic. You are spot on with this. Thank you wish your shop was closer to me……… Still driving my last Mercedes. I am a big fan of your videos and troubleshooting. "just a bunch of nuts and bolts!!"

  17. Avataaar/Circle Created with python_avatars Hedonistic0Frog says:

    Mercedes aren't that bad to work on. It's bmw and audi that are a real pain to deal with, like $2000 valve cover gasket changes on late 2000s bmws.

  18. Avataaar/Circle Created with python_avatars Efrem Williams says:

    I own a VW and it has plenty of those metal clips on every kind of hose. They are a pain!!

  19. Avataaar/Circle Created with python_avatars Alex Jarman says:

    Incredible video. I was about to take my pump off, I will check that first. I wouldn’t have if you didn’t take the time to make a nice detailed video. Definitely a new subscriber!! Thanks man

  20. Avataaar/Circle Created with python_avatars Justin St. Lewi says:

    Those 41 dislikes must have been the MB stealership techs that watched the video.

  21. Avataaar/Circle Created with python_avatars Chao Gong says:

    This is a simple job, with no mechanic skills, I did it on my 1999 MB ML430 10 years ago just with a screw driver. Only the rubber O ring needs to be replaced and this topic has been discussed many times on MB forum. Of course I researched first before doing.

  22. Avataaar/Circle Created with python_avatars Persian Chris says:

    Thank you, I watched just now for the C Clip install

  23. Avataaar/Circle Created with python_avatars tv says:

    Started watching ur channel this year I'm a big fan saying that time to subscribe

  24. Avataaar/Circle Created with python_avatars Lebron Jordan says:

    Don't you have to bleed the power steering pump?

  25. Avataaar/Circle Created with python_avatars ANTONIO Di DONATO says:

    That was solid! have exactly the same problem but on a ML500

  26. Avataaar/Circle Created with python_avatars Twisted Wrench says:

    These old videos are the absolute best of Eric O vids. He was just so much more willing to take time to show so much more. Now he’s still great just not as willing to spend the long hours which is understandable!

  27. Avataaar/Circle Created with python_avatars Drew Ross says:

    I used one of those mega screw drivers u line it up and push it on with the end of it

  28. Avataaar/Circle Created with python_avatars Bboy AWall says:

    This is the 5th time pulling the reservoir and the first video that put emphasis on the o ring, turns out place my mom took it just put a standard round one and it doesn't work. Kudos man

  29. Avataaar/Circle Created with python_avatars Robert T says:

    European cars the plastic breaks. American cars, everything breaks.

  30. Avataaar/Circle Created with python_avatars Tommy tommy says:

    Great complete video! I learned a lot from you. Great Job! Anyway Thanks!

  31. Avataaar/Circle Created with python_avatars Sher John says:

    Great Job buddy ! … your neighbor here from Ithaca wants to ask a question 😀 , did you notice any smoke coming from the engine bay when making a full turn left or right ( before fixing the leak of course )?

  32. Avataaar/Circle Created with python_avatars Jah Domination says:

    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?

  33. Avataaar/Circle Created with python_avatars Steven Lawrence says:

    The clip may have been easier if you had fitted the O ring to the inside of the reservoir instead of to the neck of the elbow, and used a light smear of grease.
    On the other end of the elbow, where it goes into the pump, there is another O ring, and they can leak from there too, just do the same method, the elbow pulls out of the pump body, the O ring is a standard type, so dont go paying main dealer prices.
    The S55 AMG has loads of extra pipes, and less room than this car, getting that reservoir retaining bolt out is a PITA.

  34. Avataaar/Circle Created with python_avatars Spencer Gordon says:

    in a small ontario town i got made fun of for having one of these, until the first big snow hit and i was pulling everyone out-and i mean everyone, foresters, tow trucks, chevs and fords dodges alike.

  35. Avataaar/Circle Created with python_avatars SnekuL_Xfire11 says:

    Thank you ! I have a Crossfire and its a very similar setup so this helped !

  36. Avataaar/Circle Created with python_avatars Phoenix G says:

    Jesus that car needs oil

  37. Avataaar/Circle Created with python_avatars Jacky Cheung says:

    So great your video! May I know the link of the parts so that I can rebuild my steering rack? Thx so much!

  38. Avataaar/Circle Created with python_avatars Mark B says:

    Thanks for the video showing that is very helpful and saved me money I knew It had to be a small issue. But I have to say I had 2 Mercedes from 2001 to 2011 and those are the most reliable cars ever and in all those model year the only thing that goes bad is that pump and leaking steering pump fluid no joke . I’m saying this because you were criticizing those cars and let me tell you the amount of problems you get with a GM car versus these being just a pump ring there is no comparison . I am pretty hard on my vehicles and don’t maintain them as good as I should and I have to say MB always started on me no matter what in the cold or hot heat one of the most reliable cars ever. Now BMW ,Porsche and Audi is another story ! Those are problem city. I would rate in reliability this way : MB #1 , honda #2 and Toyota # 3 on imports can’t go wrong !

  39. Avataaar/Circle Created with python_avatars D Wall says:

    Would it be smart to use a sealer on the oring when installing it?

  40. Avataaar/Circle Created with python_avatars uriel4377 says:

    how much power steering fluid is in a 2002 ml320 mercedes benz?

  41. Avataaar/Circle Created with python_avatars Tyler MacConnell says:

    Some of the German cars have very thoughtful and high quality designs; other areas are an expensive nightmare.

  42. Avataaar/Circle Created with python_avatars Donald Venema says:

    A Mercedes doesn’t need frequent repair like a GM bu8lt product

  43. Avataaar/Circle Created with python_avatars Magalie Augustin says:

    Happy to watch your video my power steering fluid is leaking went to a shop they charge me $3500 to replace all the part is it necessary? 2001 Mercedes ml55 amg
