Great Video! I've just dropped my car to garage. Was losing coolant and oil leak. Replace Fuel Filter housing, Oil cooler, seals, oil filter and cylinder head rocker cover. £800 Inc labour. If you can do this yourself your better off!
Load shedding 😂😂, great work! Do delete that egr and do the liquimoli diesel intake cleaner , it was looking really gunky. If your egr is deleted unplug it , alot of tuners forget to inform owners that you need to unplug it 👍🏻
@@RicerBenz You can stop the EGR from working without disconnecting the plug. The software says unplug it ... you can do it without I did so ..... it works great .... So when you want to restore the operation just rewrite the ECU with the original file.
Yoh atleast it wasnt the head gasket, hahahaha that radiator black hole i discovered the hard way so i dont put tools on that piece anymore had to fish with a magnet🤭👍
Hello mate, It was a great job. I have a bit different question if you do not mind. Can you please tell me how did you refill all of the coolant fluid? I had to replace transmission oil cooler and I can refill only 5.5 litre antifreeze. Thanks in advance
There’s a neat trick with these I didn’t know when making this video. but there’s a coolant hose that you loosen to let the air out easily - 12:10 in this video I show this hose th-cam.com/video/-dqNQ1Rztd8/w-d-xo.html
Wow a great job, well done - it's not an easy one for sure. Very common failure on the OM651 - that oil cooler has very thin chambers inside that do corrode through. This engine has a tendency to leak coolant from a couple of spots like the water pump and fuel filter housing and I wonder if topping up with water over time leads to corrosion and failure of the oil cooler later on. How many miles did yours have on it when the oil cooler went? A demanding job for a DIYer!
Thanks for the great comment man! Very demanding job for someone like me indeed🤣 the car has 210k kilometers on the clock (130k miles) hopefully maintenance is up to date now and it’ll be a while before needing attention again 😅 great cars!!💪🏼
I am replacing the oil cooler + oil filter assembly right now, because of oil leaking at the O-Ring from the plastic filter housing to engine block. 730.000 km with a lot of water topping up because of other repairs. But i used blue MB coolant fluid (here he fills up the red one) + "normal" heavy chalky tap water. The Oil cooler itself didn´t corrode yet (i plan to cut it open), and wasn´t clogged. I read that sometimes the water side of the cooler get´s clogged, resulting in high oil temperature --> less lubrication (no oil film) and oil pressure --> crankshaft/connecting rod bearings can get fused. I also install a plug (A0019905317) in the oil pump instead of the oil pressure regulation valve to deactivate the "economy" 2bar mode of the oil pump to set it permanently @max. power =5bar. Afaik the oil pressure is regulated by rpm < 2000 = 2bar, above 2000 rpm = 5 bar, no oil pressure sensor is in the system. With my worn out engine i think that´s a good 8€ investment.
Hi First of all thanks for the nice video content. So I actualy attempt to replace the oil cooler my self but got stuck at the EGR pipe. Could you be so kind to provide some additional information about how you managed to unscrew the back/down bolt of the EGR pipe ?? Where you able to unscrew it from the top and which tool did you use for it??
hi, i should do the same job as you. I have the gasket kit. How many hours did it take to replace the oil cooler excluding washes. I only have external oil leak, the coolant is not contaminated with oil. I replaced it a few years ago with the red one .. it is less corrosive for the aluminum parts ... than the blue one.
@@RicerBenz i'm like you too .. i watch videos on youtube, before .. during and after .... so it takes me more time than it should ... Approximately how many hours did you spend changing the oil cooler? 🤔 (H...??))👍
@@RicerBenz I did your same job ... I just replaced the set of gaskets of the cooling unit and oil filter holder. I ask you for information. How did you screw in both screws of the EGR tube, EGR side? I only managed the one at the top, the other at the bottom was too close to the bodywork, my hand couldn't fit. Do you have the solution? I don't need it at the moment because I closed the EGR. Closing the EGR valve only via software without disconnecting the plug is possible and I have photos of the inside of the intake manifold clean as new, remained so after 25.000 km of travel.
Hi, I hope you will answer my question. I bought a 2008 C200 Kompressor with 124k km on the clock. The manual says this: The cooling system contains a lifetime supply which must be renewed after 15 years, or after 250, 000 km at the latest. Have the renewal confirmed in the Service Booklet. So my car was 15 yrs in January and has half less than 250k km. If I understand correctly I must drain out the old coolant and put 3,8l of new coolant with 50% mixture. Is that correct or is the manual referring to replacing the coolant system?(Which I doubt
My Maintenance booklet says at 150,000 miles OR 15 years to "Replace Coolant". So basically drain, flush, and refill the coolant. My oil cooler happens to have a small oil leak, oil leaking down the front of the engine block, so im about to replace all the gaskets, change the coolant, change the oil, and replace the thermostat while I'm at it. Think I'll replace the upper radiator hose also
Love you channel! When De Catting the 220, do you need to add a fooler sensor? Or re do mapping? I suppose it will have a engine light if you remove it.,thanks
Thank you!!! With this one I took it to a guy that apparently turns the sensor off in the ECU but I'm not entirely sure how that works and then while he was busy on in we did the mapping as well. Correct without that you will have a check engine light...
Hi my car has an oil leak and the mechanic thinks its the oil cooler. He recommended that we get an original part from Mercedes instead of one from Goldwagen. Did you have any other issues with this one you got from Goldwagen?
@@RicerBenz Yes I think seeing as you had an issue with the one you bought from Goldwagen I will stick with an original one. It is more expensive now (R3190 for the cooler), but will save money in the future.
@@RicerBenz Sorry just a last question, sorry for spamming you with comments 😁. Would you say replacing this oil cooler would take a mechanic 6 hours to replace?
@@francoisdevries1 no problem man🤣honestly it’s a very shitty job. I was curious what the hours labor would be for this. But yes I would believe it should take around 6 hours to complete 😅
Get an original Mercedes part, this is a weak point and I’d prefer R&D from OEM rather than low cost copy spares. When I bought one in Australia it was cheaper from Mercedes than copy parts.
Great clip, what did the cooler assembly cost? Have you removed the cooler from the rest of the assy? Just asking to hear if it was actually the cooler core that failed or as it’s most common the cooler seals, since there’s a higher pressure in the oil system it tends to push oil into the lower pressure cooling system.
Thanks for asking man. Yes I changed the entire cooler because it is really cheap. Under R1000 (here in South Africa). Might have been the seals but because I did it myself I saved a ton on labor so just went with a new complete unit👌😁problem is gone now so I’m happy eitherway🤣
I've just come across this same problem. How do I know its not the head gasket? is it a case of eliminating the cooler first and if there is still oil mixing then its the head gasket?
Hello mate, It was a great job. I have a bit different question if you do not mind. Can you please tell me how did you refill all of the coolant fluid? I had to replace transmission oil cooler and I can refill only 5.5 litre antifreeze. Thanks in advance
I’m sure some coolant stays in the system and doesn’t drain completely. Hence why I flush a couple of times and then fill it up. Probably not the correct way but not much I do is🤣Goodluck ✌️

Just had an oil analysis showing a trace of coolant. Seems like this is the likely culprit. Probably will have it replaced as a preventative.

Good day I have a merc W204 need to replace the oil cooler for the gearbox is the a big repair.
Good work 👍🏻👍🏻👍🏻
Thanks man😁
the best part of this video is @7:23... I can't begin to count how many times this has happen to me. 😆 rotflmoa!
🤣🤣🤣
Hello dear . I can only change the rings ? Or change all ? Thank you
was that loadshedding 😂 great job 👌
Yeah it was😂Thanks man🙏
Hi, Great job - please advise - must I drain the all oil from the sump pan and then change this part - or can I leave the oil in?
Thanks man. I’m sure it’s fine to leave the oil in the engine. I just did the oil change while I was busy with all this😎
@@RicerBenz Thank you.
Hi i just got oil cooler replaced. But the system is not flushed properly. How to get rid of that build up oil. Thanks
I used a strong radiator flush and flushed it out about 3 times. You can also remove the coolant reservoir and give it a good clean. Goodluck 🤘
Dude great video! How did you unscrew the power steering pump so it’s out of the way? Doesn’t look like you completely unplugged it??
Correct didn’t completely disconnect. Just the main bolts and belt then it moves enough out the way👌🤙🏼

Hi I'm working on same car same problem, one question you had to move also the air compressor?
I removed it from the bracket.
I didn’t remove the hoses👌
😊
You do not show at what point you place the lifting jack? Or how to remove the plastic shield under the engine?
Was it easy refilling the coolant, any air in the system?

Hi bud. Would the oil cooler cause pressure as well in coolant tank
Hello there could I ask if the oil in the coolant is milky could it be leaking from the oil cooler gasket 😅?
I think it might be possible yes but replacing the oil cooler unit will be best👌

Bro how long did this take to do? Doing mine soon!
Did you used OEM cooler or aftermarket one?
Aftermarket👌😁
If I have just noticed that I have oil in the coolant(a lot of it) would it be okay to drive it to the workshop which is around 20 km from me?
If you’ve been driving it like that up until now another 20 km should not do any more damage than it already has😅🤷🏻♂️🤣
