I just replaced the washer tank in my father in law’s 2014 E 350. This video was very helpful. Like some others, I also had trouble getting the white cap that houses the coolant lines to seal against the new tank. After a couple of failed attempts, I slathered the tapered washer with liquid hand soap. That made it a lot easier to push the white cap on to the bottle and get it to seal. With the new tank bolted in place, I was able to reach one hand behind the tank ( the side nearest the front bumper ) to hold the rear of the cap down, that push the side of the cap nearest to the front tire down into the tank. I also found it easier to disconnect the wire on the front sensor, remove the old tank with the sensor in place and deal with changing the new grommet and sensor into the new tank on the bench. It’s a tricky job, but thanks to You Tube, I got it done 😊
As I mentioned in the original post, I tried to seal the cap twice and it leaked both times. Once I soaped the tapered washer, the cap snapped on and has not leaked..
Thanks for the video. I used it to replace the washer pump on my 2015 s212. Not sure I would have attempted it without your video. £10 part and 90mins in the shed versus £450 and a three week wait to get an appointment at the local dealer.
Thank you! I’ve been wrestling with this thing all day today You showed one or two steps I didn’t even think of. I keep remembering all these older Mercedes I had where the tank was visible in the engine compartment and we didn’t have to do all this stuff
Thanks for this in depth review. I wish you had showed us exactly the location of your leak on the tubes or reservoir so that we would have confidence that doing all the work you describe would actually solve the problem.
The leak came from the washer bottle itself, on the driver's side, approximately 4 inches up from the side. There was legitimately a hole in the side of the washer bottle. Other leaks are common from the seals around the pumps, and you can see the locations in the video! Hope this helps!
I found through experience they can leak in one of three places. The actual tank, the rubber grommet which is the most common where the pumps plug-in, or the actual pump. On my W-212 it was a pinhole leak right in the tank. Then I pull the pump out and it’s leaking out the bottom of the pump outside of the nozzle. I had that happen once with another car; I guess a sealed broke in there. So I just replace the pump today I’m glad this guy showed his video because this is a frustrating job that should be easy
Great video in replacing the windshield wiper reservoir tank. I tried to replace the tank once before, but never figured out how the tank sets into the body. We'll try again. This time I will buy the tank first to see how it fits. Has your cruise control ever not work. I have a 06 Mercedes E350 that has a message to take the car to the shop.
Ive in process of replacing one which is same and having a issue with the cap for the heater seating. I cant get it to snap in place. I have a brand new cap and bottle. How does the cap stay in place? It looks like it snaps over a ridge and cant get the cap to fully seat.
I replaced a new bottle but it leaks again. I used boat cement but it does not work. I coated inside the bottle with roof cement, it is simple and fast. I don't even needed to take out the bottle just use a long brush to paint the bottle inside with roof cement.
Outstanding video Michael. I'm in the process of doing mine and my leak is in the same place as yours (along the seam of the container). I was told you can also use 3M Marine Adhesive Sealant on the leak without having to replace the entire unit. Just want to get your thoughts. Thanks!
Hey Kenneth! I actually tried to re-seal the bottle with some JB Weld Plastic Epoxy before replacing the part. After two attempts and still having everything leaking, I just chose to replace it given how much of a pain it was to get in and out of the car. That being said, the 3M stuff could work better, or it's possible I just didn't do enough prep to make sure it would all seal. Best of luck!
@@heymigo Again, great video Michael and thank you for getting back to me! I'm probably going to play it safe and replace the unit. I'm having a heck of a time with that problem bolt you had mentioned. My car also has a metal bracket covering it with an opening on top that I can't really get into and get the bolt. Just my luck. Thanks again for getting back Michael!
@@kennethphillippe9239 That bolt was a pain in the neck even without extra stuff in the way. Others have suggested some other options in the comments that could work (like a ratcheting wrench), but I never got anything to fit and just had to keep fiddling a tiny bit at a time. It doesn’t show in the video, but the first time I did that bolt, it was a few hours of attempts (you know, work for 20 minutes, take a break for 20 minutes, work for 10 minutes, spend 20 minutes googling literally any car to replace it with…). I found that you eventually get a rhythm, but it’s no fun.
The side of the reservoir itself. There's a seam and it had started leaking out of the seam. I attempted a repair with a patch, but upon testing it still wouldn't hold water. I didn't want to risk it, so just replaced the whole thing.
Thanks Michael, I can see how the part numbers can be confusing, this is what Pelican Parts told me Part# 204-869-03-00-MBZ, curious if that's the same part? ...also for a W212 E63 wagon.
The most daunting part is getting that white lid snapped back on, it does not go on without a fight and it didn't look to me like you had it on correctly, I could be wrong but from what I saw it didn't look locked down.
I think I have the same problem - I cannot get it to snap into place or seal properly. I am unable to get sufficient force using my hands or adequate access once the bottle is fastened into place. I replaced all the grommets and seals(including the cap seal) and it still leaks from the top area - so assuming it's the white cap.
@@joejackson5156 I gave up and sent to a shop to complete the job for me. They replace the bottle.. still leaked and then replaced the pump (which I don't believe was the problem, but the new bottle and pump resolved the problem.).I might have persevered, but the frustration and scraped knuckles and 30 minutes each time to get the top bolt in place and loosened/undone each time was not good for my emotional health, and so I ended up paying someone else for the priviledge.
I bought mine straight from the dealership so they could tell me exactly which ones I needed based on my VIN, but my dealer sells parts at pretty reasonable prices, so it wasn't too bad.
Nice 👍 Signed up to MB Club here in Sweden and in the membership it included access to Benz EPC catalog so can look up all parts from home computer and order. Don’t have any Benz dealer here in arctic circle doing all order online from Germany! This video will help me to replace the grommets 👌

@ I struggled to get mine to snap shut until I put soap on the washer. Once I did that, it went right on. I am not sure what other advice to give you…
@ thanks for the quick reply. I’m going to try that today after work. 👍🏼👍🏼👍🏼
@@billm4212 I should have done that.

I love you bro my BOTTLE IS LEAKING SO THIS DEF HELPS THANKS BRO BLESS UP
You've done a great job, Michael! Thanks for sharing.
thanks for doing this one, very, very helpful as my C300 has a leaking reservoir. With any labor intensive Mercedes task it pays to DIY... :)

Use Henry rubberized roof cement, cheap, fast, and reliable fixed.
Do you know how to change the driver side headlight washer nozzle ?

Thanks! I've been lucky that the cruise control has always worked just fine so far. Good luck with yours though!
Thanks for your informative video
Hi Michael. At 23:03 is that a check valve? Why don't I see it in any parts diagram for the W212?

Hi There.
Where was it leaking from? The pump gasket grommets or crack on the reservoir itself?
The side of the reservoir itself. There's a seam and it had started leaking out of the seam. I attempted a repair with a patch, but upon testing it still wouldn't hold water. I didn't want to risk it, so just replaced the whole thing.
@@heymigo thanks for sharing. Mine seems to stop leaking once the fluid gets below the pump level. Planning to take it apart and investigate.
The heating element inside the bottle is connected to car's cooling system. MB way to keep the "fluid" warm and not frozen.
Ha, clever. I had assumed the opposite (helping to cool things), but good to know! Thanks for the comment!
Thank you..excellent job
Great video, would you happen to know what the approximate cost (ballpark) for this repair would be at MB for parts and labor?
Thank you! Repairpal quotes it around $400, and I believe my dealer quoted >$500 all in
@@heymigo thanks !

Everything was spot on except the part, with the off the counter windshield fluid. Always use Summerfit, mixed with distilled water.

Nice work you got new subscriber!
Dam Mercedes, I replaced my C300 washer bottle two times already. The washer bottle of Mercedes all defective at the seal joint of the bottle parts.
thank you, very helpful video.
You're very welcome! Glad it helped!
I know this is late but that not transmission cooler lines.
use the ratcheting back wrench not socket wrench for the top bolt...
