So i had a similar issue of a coolant leak on my CLS. Just a bit of advice perfoming this service yourself; replace both sides of the actual hoses and just go ahead and replace the actual control valve that the hoses plug into. If anyone needs part number i can post them, dont have them with me right now but it was a pretty simple job. Definitely not worth paying Mercedes-Benz or any other shop $1600 when the parts are less than $200
Thanks for your comment and support. Yes please post the part numbers, additional insight and valuable information goes a far way in helping solve issues more easily.
Wow, how does your hand fit in to remove that firewall/bulkhead/heat-sound-shield ? The screws are located down low and with your V8, the available space for your hands would be like near zero. Amazing. Great video. Thank you.
😂It’s pretty tight, but was able to get it done. I was unable to video when I fully removed the silver heat shield which provided a little more work room. Thanks for your comment, happy the video is helpful & being well received.
Was it very difficult to remove and reinstall the heat sheet? It was hard to remove hoses and you needed to order new one. How about, was it easy to put new ones back? Thanks.
Thanks for your support & comment; it was a tedious process as the video documents, the heat shield was removed entirely and it requires a good degree of patience to remove all the obstruction and slowly work the shield up & out from side to side & keep in mind it is very sharp around the edges. To replace the hoses was pretty simple especially since I had lubed the area in order to remove the old ones that wedged in over time.
Great video. Thank you for sharing/teaching. Someone did this very same replacement by taking whole intake out. Your method is easier and more logical approach. What was the mileage of this car when this leak happened? Could you also share parts numbers you have used for this work? Thank you for your time.
Thanks for your support & comment; happy the video is helpful & is being well received. I believe the mileage was a little past 105,000. The part numbers are A 2128300496/ZGS001 for the part closest to the firewall & A 2128302300/ZGS001 for the part directly connecting to the engine. I believe the video catches the part numbers as well briefly, but you would need to pause to get them. Again I thank you very much for your response.
It’s tricky to diagnose a problem that I can’t analyze. It’s possible this could be the solution, but it’s also possible your issue may be due to other circumstances. I suggest that you get a good mechanic to give you a diagnosis or second opinion and then you’ll approach solving with the most knowledge. This particular problem I solved though is unfortunately too common on Mercedes.
Me? Yard man, me glad fi you, but personally, me would a neva buy any of these German cars; the parts that make them are inferior, and these are the headaches you have to live with. Thats why it no mek no sense own them out of warranty. Glad fi you still, you know how fi fix them.
I really don't remember how many bolts hold the heat shield, but if I had to guess I would say 4. 2 10mm to sides & 2 to the back. Finesse is definitely required to get the shield out; I couldn't video everything because needed both hands. The shield is sharp so be careful; maneuver the wires & hoses out of the way then gently guide it up.
Take the heat shield out entirely after disconnecting the two pieces; take out the retainer clip and use a little lubricant to soften the rubber seal through the retainer groove, then wiggle and pull gently. Good luck on it, use a magnet to help remove the retainer clip so you don’t drop it. Watch the whole video so you don’t miss anything.👍🏾
Thanks for your comment. Watch from the 23 to 25 minute mark on the video where I show more details about the clips. The dealer only provides retainer clips with the female connections.
I wonder if the E class has the same firewall seeing as they are platform mates. I need this done on mine. I already had the turbo coolant lines, radiator, thermostat and water pump. I am in N.FL Where are you located? Edit: BTW got a sub for just showing this "hidden panel".
Happy you liked the video & subscribed, your support is greatly appreciated. Extremely pleased that my work & video is proving helpful to others. I am in South Florida, but that job I did in SW Florida. Remember that heat shield panel is very sharp so be extra careful when maneuvering it. Good luck on your repairs 👍🏾
The control valves should be a maintenance item they get brittle in 5 years +- and always crack and leak. You only find out later because its hidden. Wish they were metal not plastic
When I saw all the plastic integral cooling parts from so many of the newer vehicles, I remembered that employment security which modern economies are dependent on, is paramount to automotive engineers and manufacturers over durability. Clearly metal is the best material choice for these kinds of hard to access parts, yet we get the inferior plastic; it's a deliberate design sabotage and it's not only happening in auto parts.
Yes unfortunately; manufacturers decide that job security for dealerships & the parts industry is more essential than quality products for consumers. This is how we use physics now to maximize profits; as soon as many things are out of warranty, failure occurs. Easily this problem would not exist if the part was metal.

@@turbotoyzrus6286 Thanks a lot for the information. Again, your video is very helpful and unique.
My turbo coolant hose on my 2016 cls550 keeps bursting. You think this could help ?

How many bolts on the firewall shield? And what tools did you use to get them out?
I really don't remember how many bolts hold the heat shield, but if I had to guess I would say 4. 2 10mm to sides & 2 to the back. Finesse is definitely required to get the shield out; I couldn't video everything because needed both hands.

Mine just burst today , how did you get to the plastic piece that connects to back of engine ?
Take the heat shield out entirely after disconnecting the two pieces; take out the retainer clip and use a little lubricant to soften the rubber seal through the retainer groove, then wiggle and pull gently. Good luck on it, use a magnet to help remove the retainer clip so you don’t drop it. Watch the whole video so you don’t miss anything.👍🏾
@@turbotoyzrus6286 I’m just seeing your response , but that’s exactly what I did yesterday , thanks for posting this vid it showed me the way
Didn’t the new hoses come with those clips??
Thanks for your comment. Watch from the 23 to 25 minute mark on the video where I show more details about the clips. The dealer only provides retainer clips with the female connections.
No
I wonder if the E class has the same firewall seeing as they are platform mates. I need this done on mine. I already had the turbo coolant lines, radiator, thermostat and water pump. I am in N.FL Where are you located?

@@turbotoyzrus6286 what is that 90 elbow called at the 13:31 mark? I need that piece it actually corroded/rusted off!
@@turbotoyzrus6286 I like your definition "it's a deliberate design sabotage" It is straight to the point :)
👍🔥🔥🔥🔥🦾
These car makers insist in making plastic parts on everything
Yes unfortunately; manufacturers decide that job security for dealerships & the parts industry is more essential than quality products for consumers. This is how we use physics now to maximize profits; as soon as many things are out of warranty, failure occurs. Easily this problem would not exist if the part was metal.
