Extremely helpful video. I think you saved me at least three days of messing around trying to figure out how to get that out.

Thank you so much for convincing me not to replace this. That is soooooo much more work than anticipated.

One of the best, if not THE best videos I've watched on Mercedes repair. Great detail end explanation. Exactly what I was looking for. Thank you, and please keep up the good work...

You are a complete rock star. My daughter inherited my 99 and the reservoir of course was brittle and cracked. I could not figure out how to get the new one into location and after watching your video.. boom it's done. Thank you and God bless!

I was ready to give up until I viewed your video. Purchased a fluid reservoir from a junk yard for $12.95 (used) for my 2003 Ml 320. Works like new. Thanks for your video.

I agree that this is one of the best How to Videos for the ML Class. Your descriptions and Cautions are on the money. Mercedes engineers are great in F1 but they botched this up. You have saved the day however!. THANKS!

Thanks for the Video. What an effort to change the reservoir…. Crazy

Your videos are absolutely fantastic. Very clear description of tasks, required parts and tools. The arrows that you use to point to bolts, fasteners are also a tremendous help. Thank you so much for doing this, it is incredibly helpful.

Good camera stability, nice circling of the fasteners in question, very clear on things that could break and descriptive on exactly what needs to be done to get parts out. Very good instructional video. I wish everyone could be this good.

Omg. You weren't joking!! This explains why the ML55 I just bought came with a busted tank. They weren't gonna go to all of the effort, haha. Thanks for another great video! I'll come back to this when I take on the job

Perfectly filmed and detailed instructions .... VERY well done thank you for sharing

Hi, watching your great video again! My tank became very brittle, so had no choice but change out for a new one. I followed your instructions, also loosened the bolts at the electrical fuse box. After all it wasn't as hard as I thought it would be. Taking out the old tank, I didn't have to remove anything, since I wasn't concerned about damaging the tank. Thanks a lot!!!

GREAT video! Walked me through getting the new reservoir in and it was a breeze, albeit ridiculous how much is in the way :D loved all the finer detail pointers as well. Thank you!

Thanks for your work. I struggled with the washer bottle change over for hours until I saw this. On bolting the fuse housing gave me enough wiggle room to get it in with no problems at all. Well done 👍🏻

BEST demonstration that I have seen! Thank you for your hard work in putting that together!

Excellent tutorial, I'm half way through dismantling. You are right about that corner lol.

Great video for replacing the window washer tank. So appreciate the detail instructions. Thanks a lot👍 11:06

What a wonderful video - thanks for showing the installation as well. Normally just saying to do it all in reverse and leaving us hanging... the reverse never works out well. Awesome vid

This is one of the best DIY videos I have ever seen, love the details in it. I noticed that my ml270 2002 had 2 mornings in a row a small pond bellow the car...I traveled to work, checked it during the day...no leak, next morning...pond appeared again. All I know that it will just get worse and honestly after seeing this cursed disassembly(no offence, this one goes to mercedes designers), I ll just sell the car for spare parts...I changed so much things and drowned so much money in it, that at this point that car is just laughing at me. Every month just more ridiculous things broke down 😢

When you come to Western Australia for holiday, dont worry about the tools as i have them already. Amazing video tho!

You are a super star love to watch your videos as very detailed this one amazed me on how mutch you had to do just to replace a water container which I have to do thanks❤

Thank you so much!!! Best regards from Germany

I can almost hear the conversation between Marketing and Engineering on this one. We must have an 8L tank! No, it won't fit. Do it or you're all fired! Ah, the Mechanical Engineers said we can do 7.6L but Production is throwing a fit about assembly and repair! Haha, they lose. DO IT!

Beautiful presentation! Thanks for the videos.

Great video... thanks for all the careful instructions

Very good video. No muss no fuss, just the procedure and ALL of it. Thank you. Thank you. Thank you. One question. It appears in the after market there are tanks with 3-Holes and Tanks with 4-Holes. Comments?

Brilliant presentation and video best I've seen on the web.

Excellent demonstration, very helpful 👍

Hi, thank you so much for this video! Worked perfectly!

Thanks. Going to replace my leaky reservoir for the 3rd time now. Seems to leak at about 5 years. They could have used the same plastic as the coolant reservoir!

Amazing presentation Lady !!!

Proper demonstration thanks n blessed time

What would be ideal is if some BRILLIANT aftermarket supplier would create a "retro-fit" smaller Washer Fluid tank that would fit easily & remove easily - yes it would need to be a smaller capacity than 7.6 litres but that'd be ok to eliminate this hassle. On this point, the early MLs were better !

Excellent vid. Thank-you!👍😄

Thanks so mucho for this video so worked for others

Michael, is that you? Didn’t know you were an awesome mechanic! Great video

Great video

MB keeps many screw companies in business, for sure

sadly Mercedes seems to have used plastic material that is inadequate. i was unable to find an unbroken reservoir in any of the scrapyards i searched. mine is so brittle it crumbles at the touch.

Excellent video. Should not be this difficult, but how else are engineers gonna get their jollies? Probably use videos like this at their conferences to get laughs, the slugs. One piece of tech advise to all car owners, Never use tap water in windshield washer systems, the minerals build up in pumps and nozzles clogging them up. You say you don't use tap water? If you go to a fast lube oil change place, you have tap water in your reservoir. A solution of Dawn and water cycled through the system will eventually clear it out. If you use the blue stuff, don't dilute it, if you use MB solution, get a gallon of "Distilled Water" from Walmart or Costco and use that. Also use Dielectric grease on electrical connectors and around the fittings on the ABS lines to help prevent corrosion. Kudos to you L35, was hard enough doing the job, adding the video aspect tripled your efforts. Does not go un-noticed.

great vid

You are awesome thank you!!!

I’ll probably do it without taking out the fuse box. I’d suggest using a water pipe black insulation foam for that sharp corner

great video, thanks for sharing!!! where was your leak? somehow I couldn't make it out in the video

Use Henry rubberized roof cement, cheap, fast, and reliable fixed. The same price of a 3M tube can buy a ONE gallon can of rubberized roof cement from Home Depot or eBay.

thanks was quite helpful

So... My top frame isn't lining up and im a little stressed out. Not sure what to do at this point but i am taking a break to regroup

Thank you so much

Great video, thank you very much. I had so bad reservoir that i simply destroyed it and dragged out in pieces :D Don't you know part number for the lid? I've lost mine.

awesome job! subscribed!

I am looking for the older version of the winshield water tank (show at time 0:18 of your video) for my 2001 ML320. Do you (or you know any website) have one for sale?

Wow what does Mercedes charge for the bottle replacement?

Wow! where were you all my life? Borovooo.

Awesome

Where can I get that little clip for holding in the headlight molding/trim? Thanks!

All that work for the fluid reservoir. Mine can stay broken

very Nice!!!

You don't need to remove the front top support I got mine out no problem it's right but not too hard but if you can't loosen up the fuse box it's easy I hard to replace my esp4 ABS module tank went back in easy

It's definitely not that hard to remove on the 2000 ml320. Just unhook all the connections remove nut holdin reservoir to frame and then just pull up and wiggle. Comes out every time.

where at in colorado are you? do yo u want to work on my ML350? :)

Too much work… I just removed the first screw on the left side and then I pulled the whole box out of the piece very easily, all in all it took five minutes

Bendede aynı araçtan var takip ediyorum sizi ama dilinizi anlayamıyorum türkçe alt yazı olsa çok daha iyi olur sizin için zor olmazsa teşekkür ederim saygılar

Wow Mercedes fucked that up.

Michael Jackson is that you?
