Mercedes Sprinter Van water leak repair rooftop Air Conditioning

Torx T27 inside the van.
Torx T30 upper rooftop cowl.
Torx T25 lower rooftop cowl.
Cross member has 4- 13mm bolts, and requires a T30 and a 10mm socket to remove condenser support bolt.
I replaced the T30 bolts which were 6.0 mm x 1.0 pitch and were 12mm long with stainless steel bolts that were 16 mm long and had a 10 mm head. I also added a stainless steel, larger fender washer....
I used GE silicone 100% 2+, in a standard tube. Recommend smaller tube for getting it into the tight bits.

[@albertovaldez8882]

Thank you! Your video was a lot of help

[@rziegelbauer]

This is very helpful!

[@naluryder]

Thanks for sharing!! Did you have to evacuate the refrigerant? Now after watching I have more confidence to fix my leak👍👍👍🤙🏾🤙🏾

[@marcram01]

Wondering the same thing

[@kienanmaxfield6288]

No, you can leave that in tact.

Several forums discuss the difficulty of repairing this leak. The mechanical steps are simple enough, the real challenge is creating a lasting seal. Has the silicone continued to work for you? Any updates after several months of use?

[@kienanmaxfield6288]

I’m wondering the same thing. I am going to be using a product I have use for many other things. I think is really spectacular. It is made by ChemLink and it is called “M-1 Universal adhesive & sealant.” I will be very surprised if it ever leaks, but if it does, I will certainly post an update… The only problem is that I doubt that I will be able to lift this plastic piece once it dries.
My alternative idea is to use Dicor self-leveling lap sealant. It is used for trailer roofs. It never hardens, and it would be easy to remove later, I just don’t know how permanent the seal would be…

​@@kienanmaxfield6288 No problem since, not one leak and it’s 2022….
Bead has lasted beautifully, so 3-4 years…

Thank you!!!!!!!!!!

[@bouis007]

thank you . just did mine

[@aktechstack]

Thanks! How did you know it was leaking? Where did you notice the water?

[@williamgauthier8460]

Great video. I was wondering, do you know the dimension of the hole? I was wondering if I could remove the AC unit and fit a Maxxair fan in there...

[@oregonbigfoot4877]

No the hole is too big Maxx air fans are 14x14

[@surfmarko]

Thanks!

What year is this van?

[@YFCao]

Is it necessary to empty the refrigerant?

[@kienanmaxfield6288]

No

Did Mercedes Benz fix this problem on 2016 models or should I start putting some silicone beads on mine before it starts leaking?

[@tylerdallas8927]

My 2016 is leaking and the dealer wants $1600 to reseal it. I had a 2011 with the same problem and it took a class action lawsuit to get their attention and have them fix their know issue. Very disappointed the leaks continue.

[@idabeauty]

@@tylerdallas8927 Any luck with the law suit? My 2017 leaks. Dealership have tried fixing this twice and the problem remains.

[@stevemaglior9522]

My 2018 is leaking. Does anyone know if what years the recall include??

[@norseman6899]

'14 is leaking.
