Well the most important parts of the video you skipped over what bolts to remove and fixings etc but still helpful maybe take time next time to do a more in depth video. Thanks though
Awesome video, im glad I found it! Just replaced the water pump 2 months ago and then this %)/'"%=/+" started to leak now... Straight to the point, thank you for the content!
Thank you very much for this. Been topping up my coolant for last couple months but couldn't see where it was leaking. Just took off the engine cover, looked down the side of the filter and can see the water sitting on the top of the manifold. Thanks again for your great videos. Cheers, Jon.
Great short yet very informative video. In my case the coolant was gushing out but with the help of this video i will soon be changing the housing on my sprinter.
Thanks for this info. Our Daily runner started with this problem one year after water pump was replaced. This can be the problem as I checked and saw some green coloring in the same area where yours had water. I might just go ahead and replace the damn thing next week.
After watching this last night and doing my sprinter today, You can do mine next time.... talk about frustrating. Especially the underside EGR cooler bolts. Even If the loom would move a little more, it would have been so much easier 🤣🤣 Thanks for the insight, made it so much easier
Thanks so much for the great video but how on earth did you remove the egr cooler bolt which is under the fuel filter housing?? The ff housing seems to prevent access for a socket to get to that bolt
Can you explain why the “new” housing has 3 fixing/ mounting holes while the original on only has 2? Are the bits interchangeable? Is this an upgrade? Or is a hole not used on the refit? Thanks
a very useful video really clear... Thanks for posting... But would have been so much more useful if you could have shown the actual mechanics of removal and reinstallation... Anyway.. thanks!
Happened to me with infiniti Q50 (same engine) but the upper house inlet was damaged. Another common issue with this engine is the plastic water pump, which can be replaced with aluminum pump 👍
i have use same this model. my question is. i found the oil leak come out from the hose beside the gearbox. had see with my tiny camera and the hose is attach to cylinder head. i dont know why it is there and oil come out from that hose. what is you opinion that i need to replace sir?
Where does that air filter housing sit on? I put the bolt back on that holds a cable in place and used a longer bolt and hit something. Me being a noob used an impact and kept trying to drive it in, until i figured out i used a long bolt instead of a short bolt. Not sure what I was driving into, and i still have a leak. not sure if i broke something, or if i just didn't put a hose back in right... Just wondering worst case scenario, what did i break (if anything). Where does that housing sit? any help is appreciated!
Great vid man replaced heaps of them in mb the part you fitted is an uprated one (re designed) also the water pumps have an update aswell the newer ones are aluminium instead of plastic never see one give trouble
Can you please try to explain to me how to get the bottom middle position bolt out on the EGR Cooler??? I have all the other bolts remove but can not comprehend how to get that one out. I feel so fucking stupid right now I’ve done engine swaps and whatever you can think of, but this job has me stumped.
If you can get your hands on a 1/4 drive e10 socket and a long 1/4 drive extension from the front of the engine it is pretty easy with a 1/4 drive ratchet.. all the best 👍
Good job man, just for info I had an issue with weeping from this area and water pump, but a split hose from this (fuel filter water block) housing to oil cooler which was leaking massively.
Hi, Thanks fo your comment. Before I go stripping my car - can you please advise which hose you refer to? And how did you identify it was the hose. Thank you.
Subscribed already! I have changed water pump with housing(aluminium housing), i had problem on it with coolat leak, so now it it new and it is ok. But i still can see coolant dissapearing, less a lot than before changing water pump, but it somewhere leaks. Could this be a problem, or something else? All pipes of water are "medium soft" temperature is always 90°... and i am dissapointed because all of this. Btw everything is great with car e250cdi, injectors, transmission,etc. No oil in coolant, and no coolant in oil. I hope so its not big deal? Best regards
Sehr gute Job 👌. Wie würdest du vorgehen genau bei diesen 2011 er Model um Ölkühler zu wechseln? Musst auch die Servolenkung behälter ausgebaut werden? Danke
@@mercmantips Maybe im sad but id 100% prefer to watch you unscrew bolts etc. Especially with jobs ive not attempted before, like to see exactly what you take out first
Can you change mine for me please? Also got a boost pressure warning mercedes says it needs new turbo 3 grand after replacing intercooler hose which was split!
Took me 6 hours to complete on a C220 Amg 170, and i have an engine management light now on which ill have to inveastigate, the wiring is a pain in the neck and gets in the way making an easy job really tricky, access to several bolts is tricky without a decent socket kit. The video diagnosis is very good but its not a quick job.
thanks for the video. But as i can see the egr cooler needs to be removed. But it got several bolts that needs to be unscrewed. There is a bolt underneath it, isnt it hard to take those out?
I am having issues with my C220 Auto seems to have a coolant leak of some sort, Twice the bottom coolant hose has come off while stationary at just below 90 degrees engine temperature, giving off steam and immediatly warning me of low coolant, the engine doesnt overheat, heater controls work fine hot and cold. Another issue that might be related is i get alot of gushing liquid which seems to be water coming from the exhaust. (like a tap on full when reving/Accelerating) Can you (MercMan) or anyone reading this help me, thanks
Today I tackled this as it would appear I had coolant leaking from underneath the car and warning on dashboard and when you looked around by the fuel filter housing and the egr cooler there was a build up clearly showing however I've fitted the new redesigned model can only fit two bolts as isn't slots for all three. However I took it for a test drive after refilling with coolant and now it appears the dashboard warning has came back on yet again? Any ideas or suggestions to what's happening?
Once you change a part on the cooling system even when you fill the tank with coolant air can be trapped in the system and when you drive the air will be released and the coolant level will drop a little, so id just top up and see how it goes from there
I am watching your video because I had the same problem with mine, and the mechanic at the workshop whilst having a go at it, decided it would be a good idea to remove the Common Rail to gain acess. After reassemble it , wouldn´t start, and he cranked it till the battery was flat. He also used Easy Start. Injector were sent to a specialist and the result is all four are damaged. I am faced now with the prospect of having to spend 800 quid in four new injectors. And worse still, maybe a fuel pump. I Was told that the problem is because " this is a high mileage car" . I am very disapointed and frustrated. What would you do in my sittuation? Thank you for your video, I wish i had seen it sooner and had a go myself.
Hi Mike, sorry to hear your story, you do not have to remove the rail at all, the OM651 engines injectors do tend to ‘block up’ when removed or any high pressure fuel lines removed, when removing injectors or any fuel lines you have to block up the holes so no dirt gets in the system as it can damage the injectors.. i don’t think the fuel pump will need changing but I’m not sure what else the mechanic has done, in this case you need to change the injectors and take care even when installing the new ones so no dirt gets in them..
had this happen on a glk 250. i think the gasket/o-ring from manufacturer is bad. i took to dealer, they replaced water pump... $1200 out the window, after i told them this was issue. fixed myself took about 4 hours, wish you made this video 3 years ago
if it's anything like mine the collant will remove itself. You don't need to drain all of it, just as much as it takes to get down to the level of the leak. I put a pressure cap on the reservoir and kept it under pressure until it was empty and blew bubbles. pop a bucket underneath and catch the joice as it pours out. Strain it going back in and you're golden ;)
Hi man, I changed the oil filter housing with your help but them I noticed that I don't have the vacuum box on top of the EGR and I can't seem to find it anywhere. Can you please tell me how important it is and how could I find that part? Thanks!
Hi, thank you for your video - note that the new part has an additional hole !!! but useless as the additional hole is not on the Engine. Mercedes mugging people off.
Nice video! Thanks for sharing. How did you remove the lower-center screw of the EGR radiator? I think it is a problem to put it back in place. I am planning to clean my EGR but I am stuck a t this point.
Hi, i have a 1/4 E10 socket which i use for the screws on the cooler, the centre bottom bolt can be tricky but i use a long 1/4 extension with the 1/4 E10 socket and do it that way, when putting the bolt back on i put 1 layer of paper in between the socket and the bolt so its nice and tight and does not fall down whilst trying to get it aligned up with the thread hole.. hope this helps, please subscribe to the channel 👍
Cheers for the video... can I ask though, why did you use an E10 socket when the bolt head is E8? Did you end up ruining the head on the bolt underneath?? Cheers.
This looks like the trouble mine had. It's easy to see if you pressurise the system until it blows bubbles out of the failed seal, you can see and hear it then.
Which socket do you use to get that awkward Access bolt from lower section from inside the filter housing. Appears my e10 is a little to fat and awkward access
@@mercmantips I do like the new redesigned one has changed to normal bolts instead of the e socket and more accessibility for a socket to actually get into it. Odd that they created the third bolt access though. Guess easier to make a batch of all models instead of both models with a larger fixing point
Hi, thanks for this guidance video! I’m having a hard time removing the hoses that connect to the vacuum box. Do these need to detached in a specific way, or do you just use force to pull them off?
No just put in enough coolant, get the engine hot enough for the thermostat to open then it will bleed it self and coolant level will need topping up..
Thanks Mercman great video mate. I just replaced mine after suffering coolant lose and advise from Mercedes. When I stripped everything down I had the three bolt variant present already (with the horizontal bolt from frame) and everything looked quite dry. The bottom bigger bolt in the fuel filter housing is difficult to tighten due to the base plastic getting in the way of the socket and the bolt on the bottom left of the EGR cooler is a nightmare. With some trickery and blue tac to hold the bolts in the socket I have managed to get everything back together. Can I ask if you torqued these bolt on the fuel filter housing or EGR cooler or just tightened by feel till they felt tight enough? Also as mine is dry and water pump area is dry have you seen any other common areas that leak? I have noticed coolant sat on the belly plastics under the car close to the back of the engine when they were removed so I am assuming somewhere round the back.
There is one pipe that goes from the fuel filter housing to the heater matrix, where it connects to go inside the car is a plastic housing, that cracks and leaks too check that out
@@rudey7777 thanks mine turned out to be water pump seal. Caught mine when it was not as bad so not much discolouration on the engines metals from the leaking coolant which made me originally miss it. Replaced the pump and seems to have been fine since.
Hi, Thank you for your hard work and insightful solutions to the OM651 problems. I'm running out of coolant. However, when I look at the car from the front, I notice that on the right hand side, on top of the radiator, the hose leads to a metal housing that appears to be wet and rusty. Is this the most likely culprit? I'm not sure what the housing section is called. Please let me know. Second, now that I'm checking for leaks, when I turn off the engine, it makes a beeping sound. Could you please tell me what's causing this? Thank you very much.
Hey there. I'm going through this particular small nightmare right now. Where did you get the new part from? I'd like to avoid my local Merc dealer (they're temporarily closed now anyway thanks to the pandemic) and I can only find parts on eBay that are either S/H or from far off lands. Thanks.
Hi Bryan, to be honest i will only buy it from Mercedes because its not that expensive its around £40 and also the new parts are slightly modified so they don’t break again so i will not fit a second hand one if i were you.. some merc dealers are open it depends where you are located
Does this also allow coolant to leak down the oil cooler side of the block and to the floor, I recently did that oil cooler job and when I topped up the cars coolant (it came with virtually non in) I had a leak down that side. I initially thought I'd made an error fitting the new oil cooler so stripped it all back off and everything looked fine. When refitted again, leak was still there and after a check with an endoscope the leak seems to be coming from above the oil cooler.
@@mercmantips I think so too, the oil in the coolant system seems to have damaged the water pump seal and I think it's pushed this filter housing seal to break further too. 😳 A lot of faults for such an expensive and fairly new car... Glad i don't own a merc lol
The housing is plastic usually what i find the the parts where the hoses connect onto just crumble and break so its most likely the housing mate, the part is only around £40 so go for that
Hey!!,quick question for you...would really appreciate help if you could? There is a wiring harness that runs on top of that engine and a plug that comes off on the middle right side,the plug seems to sit around the front of the fuel filter housing and goes down to the left side front of the egr cooler,do you know what it goes to? Its just a little short wire and plug on the right of the wiring harness and only one in the middle on top of the fuel rail. Ive just done the waterpump and fuel filter housing on this and lost to where this plug goes unless it doesnt on some of these engines?
If its what i think it is, it plugs onto a sensor which is connected to a fuel line, the sensor is probably trapped under the egr cooler somewhere hence why you cant see it, msj me on my instagram with photos and il try to help
Hi Mercman, iv been watching your vids for a while and like to do my own car DIY. I have a om651 and found that my serpentine belt had come off? there seems to be oil substance coming from around the water pump pulley, possibly coolant but looks a dark colour could this be coolant. do you know about any common issues with this problem? Thank you so much
@@mercmantips I have just posted a video please could you take a look at it , I have taken the serpentine belt off and checked the pulleys the pump pulley is loose and making a noise, when I start it up no more oil/water is coming out just a high pitch noise from the pulley..
Thank you very much great video! Do you know if the fact that the new filter housing has three bolts instead of two (like the old one) creates issues? Thanks man :)
Hi Matteo, the new fuel filter housing is modified with 3 bolt holes and is slightly thicker, but not all engines have the 3rd thread for the 3rd bolt, most of the ones i have fitted have 2 threads, also the new housing comes with modified bolts which are longer 10mm bolts, as long as you use the modified bolts there will be no problem...
Thanks Callum, mercedes cooling systems self bleed, just top up to max put the heating on to hot go for a 5 min drive then wait for it to cool down and the coolant level should have dropped abit, top up again job done 👍
Hi! Can you teach me how to remove car parts just by putting a hand on them? I need this skill! It took me almost 2 hours to replace the air filter on the E92 325D 😫😫😫😫😢😢😢😢
Good job dude! :) I couldn't help but notice, that the new fuel filter housing has 3 mounting bolts on the end part, where the actuall leak was, while the old one had 2. Does it mount without any problem? No leaks? :) thanks in advance
Hi, yes some models have 3 screw holes, for example i done a vito few days ago and that had 3 bolt holes on the cylinder head so i used 3 bolts for that one, but on most other models they have 2 and only used 2 bolts had no problems..
@@mercmantips Thank you serviced my 13 plate Sprinter this weekend with the same engine, it's been losing about 300ml of coolant a month and i thought it was going from the header tank but now i have noticed a small amount of coolant in the bottom of the fuel filter housing and thought i would research and found your video, thank's again Mark

Did you replace with the 2 pins or 4 pin part on the housing outlet
Any tips on how to get 3rd bolt out from under wire loom?
Can I removed EGR cooler and block inlet and outlet hose? I deleted EGR via software.
Hello Guys,
I'm just wondering when you removed the fuel filter housing, will you possibly get some space as well to replace the glow plugs?
Hey, question do you remove the coolant first or not?
Can you explain why the “new” housing has 3 fixing/ mounting holes while the original on only has 2? Are the bits interchangeable? Is this an upgrade? Or is a hole not used on the refit? Thanks

@@mercmantips I do like the new redesigned one has changed to normal bolts instead of the e socket and more accessibility for a socket to actually get into it. Odd that they created the third bolt access though. Guess easier to make a batch of all models instead of both models with a larger fixing point
Crazy question, but, is this part also on the ML420 4.0 litre V8 diesel engine as I have an unsolved water leak? Like the filming technique too.
No this is only on 220 cdi and 250 cdi
@@mercmantips Okay, thanks MercMan. Back to the drawing board lol
Hi, thanks for this guidance video! I’m having a hard time removing the hoses that connect to the vacuum box. Do these need to detached in a specific way, or do you just use force to pull them off?
I use a pick to break the seal on them and force down with a thick screw driver taking care not to split or damage the pipes
Hi, do you have to bleed the coolant system after fitting?
No just put in enough coolant, get the engine hot enough for the thermostat to open then it will bleed it self and coolant level will need topping up..
Thanks Mercman great video mate. I just replaced mine after suffering coolant lose and advise from Mercedes.
When I stripped everything down I had the three bolt variant present already (with the horizontal bolt from frame) and everything looked quite dry.
The bottom bigger bolt in the fuel filter housing is difficult to tighten due to the base plastic getting in the way of the socket and the bolt on the bottom left of the EGR cooler is a nightmare.
With some trickery and blue tac to hold the bolts in the socket I have managed to get everything back together. Can I ask if you torqued these bolt on the fuel filter housing or EGR cooler or just tightened by feel till they felt tight enough?
Also as mine is dry and water pump area is dry have you seen any other common areas that leak?
I have noticed coolant sat on the belly plastics under the car close to the back of the engine when they were removed so I am assuming somewhere round the back.
There is one pipe that goes from the fuel filter housing to the heater matrix, where it connects to go inside the car is a plastic housing, that cracks and leaks too check that out
@@mercmantips thanks mate I know which pipe you are referring to. I will wait and see if my levels drop and post back in a few weeks :).
There is a gearbox cooler which can cause this also, i replaced mines thankfully the coolant did not contaminate the gearbox fluids
@@rudey7777 thanks mine turned out to be water pump seal. Caught mine when it was not as bad so not much discolouration on the engines metals from the leaking coolant which made me originally miss it. Replaced the pump and seems to have been fine since.
Torque to 20 Nm
Wish you shown us how to remove the egr cooler I'm currently struggling to get it off
1/4 socket is the way forward
Hi thanks for the video. But do you remove coolant off the system beforehand?
No you won’t lose much coolant doing this. Do it while car is cold and top up expansion tank after the repair is complete.
Hi Mercman, what antifreeze should I be using?
Hi, Thank you for your hard work and insightful solutions to the OM651 problems. I'm running out of coolant. However, when I look at the car from the front, I notice that on the right hand side, on top of the radiator, the hose leads to a metal housing that appears to be wet and rusty. Is this the most likely culprit? I'm not sure what the housing section is called. Please let me know.
Second, now that I'm checking for leaks, when I turn off the engine, it makes a beeping sound. Could you please tell me what's causing this?
Thank you very much.
From the right side of the radiator the hose should be connecting to the thermostat housing, the beeping im not sure about
@@mercmantips Thank you so much. Much appreciated.
Hey there. I'm going through this particular small nightmare right now. Where did you get the new part from? I'd like to avoid my local Merc dealer (they're temporarily closed now anyway thanks to the pandemic) and I can only find parts on eBay that are either S/H or from far off lands. Thanks.
Hi Bryan, to be honest i will only buy it from Mercedes because its not that expensive its around £40 and also the new parts are slightly modified so they don’t break again so i will not fit a second hand one if i were you.. some merc dealers are open it depends where you are located
@@mercmantips Thanks man. That makes a lot of sense. I'm in Perthshire and the dealerships are currently closed. I'll hang fire until they open again.
All the best 👍
Hello
Whereabouts are you based as I’ need my car looking at
Does this also allow coolant to leak down the oil cooler side of the block and to the floor, I recently did that oil cooler job and when I topped up the cars coolant (it came with virtually non in) I had a leak down that side. I initially thought I'd made an error fitting the new oil cooler so stripped it all back off and everything looked fine.
When refitted again, leak was still there and after a check with an endoscope the leak seems to be coming from above the oil cooler.
It most likely is this fuel filter housing
@@mercmantips I think so too, the oil in the coolant system seems to have damaged the water pump seal and I think it's pushed this filter housing seal to break further too. 😳
A lot of faults for such an expensive and fairly new car...
Glad i don't own a merc lol
The housing is plastic usually what i find the the parts where the hoses connect onto just crumble and break so its most likely the housing mate, the part is only around £40 so go for that
@@mercmantips yeah I will bud thanks again for the advice!!!
Hey!!,quick question for you...would really appreciate help if you could? There is a wiring harness that runs on top of that engine and a plug that comes off on the middle right side,the plug seems to sit around the front of the fuel filter housing and goes down to the left side front of the egr cooler,do you know what it goes to?
Its just a little short wire and plug on the right of the wiring harness and only one in the middle on top of the fuel rail.
Ive just done the waterpump and fuel filter housing on this and lost to where this plug goes unless it doesnt on some of these engines?
If its what i think it is, it plugs onto a sensor which is connected to a fuel line, the sensor is probably trapped under the egr cooler somewhere hence why you cant see it, msj me on my instagram with photos and il try to help
@@mercmantips Hey have added you on Instagram,and sent a message really appreciate your help
Hi Mercman, iv been watching your vids for a while and like to do my own car DIY. I have a om651 and found that my serpentine belt had come off? there seems to be oil substance coming from around the water pump pulley, possibly coolant but looks a dark colour could this be coolant. do you know about any common issues with this problem?
Thank you so much
It could be your rocker cover gasket check where the injectors are and see if there is a puddle of oil near your fuel injectors
@@mercmantips I have just posted a video please could you take a look at it , I have taken the serpentine belt off and checked the pulleys the pump pulley is loose and making a noise, when I start it up no more oil/water is coming out just a high pitch noise from the pulley..
Just curious what funtion the vacuum box does.
Seems to be missing from mine.
I just replaced filter housing
It stores vacuum pressure, the newer models don’t have it
@@mercmantips ah Cool,
Mines a W204 2013 C200 CDi.
Thanks for your help
Thank you very much great video! Do you know if the fact that the new filter housing has three bolts instead of two (like the old one) creates issues? Thanks man :)
Hi Matteo, the new fuel filter housing is modified with 3 bolt holes and is slightly thicker, but not all engines have the 3rd thread for the 3rd bolt, most of the ones i have fitted have 2 threads, also the new housing comes with modified bolts which are longer 10mm bolts, as long as you use the modified bolts there will be no problem...
@@mercmantips Really appreciate the time you spent for my answers. All the best, Thank you
What is the Part Number on this part?😅
Subscribed mate! Any tips of bleeding cooling system after doing this?
Thanks Callum, mercedes cooling systems self bleed, just top up to max put the heating on to hot go for a 5 min drive then wait for it to cool down and the coolant level should have dropped abit, top up again job done 👍
@@mercmantips your a diamond mate!! Thank you
Great video how long did it take, was there any special tools needed.
Patience and hot tip is to reinstall the EGR cooler with the middle lower bolt on the tool else you will struggle to locate it
Hi! Can you teach me how to remove car parts just by putting a hand on them? I need this skill! It took me almost 2 hours to replace the air filter on the E92 325D 😫😫😫😫😢😢😢😢
Good job dude! :) I couldn't help but notice, that the new fuel filter housing has 3 mounting bolts on the end part, where the actuall leak was, while the old one had 2. Does it mount without any problem? No leaks? :) thanks in advance
Hi, yes some models have 3 screw holes, for example i done a vito few days ago and that had 3 bolt holes on the cylinder head so i used 3 bolts for that one, but on most other models they have 2 and only used 2 bolts had no problems..
Hi MercMan great video is there a gasket that is best replaced on the egr cooler.
There is one gasket inbetween the cooler and the EGR but i never replace it because it never gets faulty, never had to replace one before..
@@mercmantips Thank you serviced my 13 plate Sprinter this weekend with the same engine, it's been losing about 300ml of coolant a month and i thought it was going from the header tank but now i have noticed a small amount of coolant in the bottom of the fuel filter housing and thought i would research and found your video, thank's again Mark
No problem mark, glad its helped 👍
