[@BenzAddiction]

M272 and M273 needs these to be done to make sure the front of the engine stays clean and also to make sure the belt, pulleys, tensioner, thermostat and serpentine belt are all in a good shape and this service plus the fluid changes, guarantees miles and miles of trouble free driving in your Mercedes with peace of mind, please like, share subscribe and give me your feedback and feel free to ask questions and I will respond as soon as possible, cheers Max, Brisbane Australia.

This is a great tutorial. Thank you for doing such a thorough job. I own a 2011 S550 with the M273 engine and this makes it much easier to own it.

[@BenzAddiction]

Thanks mate, enjoy every step of your Benz ownership :)

Excellent video explaining tear down and reinstalling cleaned parts. I have a 2011 E350 coupe. So this work would be the same on mine. I happen to keep a clean engine and bay area. I do my own work when possible . Has only needed a thermostat replaced which was under warranty years ago. I'm saving this vid for any future work needed. Thanks again Mate, for a fantastic vid.

@@richo5661 You are welcome, thanks Foe watching 👀

Great tutorial, every high mileage Merc with these engines is going to have these issues. Probably worth changing the cam shaft sensors and magnets while the accessories are unbolted.

[@BenzAddiction]

Yes, thanks, I have actually replaced the cam sensors and magnets too, video will come soon.

This engine generation family, M272/M273 are those engines that in comparison to M278 and M157 which sacrifice longevity and reliability for performance these two do the opposite. I was dying to get an M278, the turbos, and the horsepower were tempting, but once I started digging into the BENZ community, I realized it wasn't worth it. The M272/3 engines are more reliable than any other Mercedes V8 engine, and I'm not saying they are bulletproof, but in comparison with the M278, man... it's a heaven-to-earth difference. I declined a 2013 E550. 42K miles for a 2011 E550 with 90 miles. Yes, It's way more miles, but guess what? I won't be suffering from cylinder scoring, nor any turbo issue, no 4matic stuff. So, I'll have more peace of mind knowing that despite this one being older and with higher mileage, I know the problems that may pop up could be addressed, and unlike the M278 I won't have to be scratching my head because I need to get a new engine.

[@BenzAddiction]

@judsonwidmymerviluszabala378 I do agree, very good point, post made M272 and M273 can be a great choice, on any car more HP = more problems. M273 with 380ish HP is enough for any car.

[@timmyb1874]

There is a specific pattern you are supposed to torque the oil filter housing bolts down, start at the middle bolt, then down, upper right, left across, down to the right, then upper left bolt last. When I replaced my oil filter housing gaskets I didnt bother draining the coolant, just pull off the oil filter housing and it drained that way. Also no need to disconnect the coolant hose and thermostat wire, just unbolt the thermostat housing and lift out of the way. After the oil filter housing was removed I then drained the oil in case there was any coolant contamination.

Thanks mate for advice 👍

I wasn't happy with the fit of the Elring oil filter housing/cooler gaskets. Too loose, and I wasn't going to use rtv to retain them. You could get by with the oil cooler gasket a bit loose if the unit is off the engine, but the oil filter housing gasket snug fit is mandatory. The housing is held vertically to be installed, and you have to rely that gasket staying in place, especially because you can't really see behind the housing. I installed oem MB gaskets for the housing/cooler. More expensive but the fit was perfect, no leak issues.

[@nv1493]

Also, the three cam plug covers on the back of the engine and the oil separator housing can be prone to leakage.

[@BenzAddiction]

@@nv1493 Great tip, thank you. 😊

Terrific video and detail, thank you. Quick question if you don't mind. I have 2007 S550 that is has an oil leak I believe by the oil cooler gasket. I plan on ordering the Nissens oil cooler unless you think I should get a different manufacturer. Also, do you think I should order a seperate genuine mercedes gaskets? Any advice would be much appreciated. Thanks again

Thanks mate, I would buy what is available but Meyle or Elring, they are both good. Unfortunately living in Australia means limited options for German cars.

In thw beginning of the video you showed a 5w-40 oil, yet at the end tou used helix 5w-30?

@@BenzAddiction Ah I see. I see. Did you have a change of heart in the middle of your service? I've read that 5w-40 is better in older benz engines. That's what I use now in my M272

Do I need to burp coolant system I have m273 engine cls550

@Abu_Zooz if you mean bleeding the cooling system, no it is self bleed, but you need to leave the engine idling for few min and add coolant and check few times after.

[@BenzAddiction]

There is a coolant pressure tester on ebay that pressurises the cooling system with a gauge, buy one and test it yourself, instead of spending thousands on replacing random parts IMHO.

bro i just bought a beautiful 2010 s204 c300 wagon at 110k miles, i've just changed all the fluids. there aren't any leaks or problems i can identify yet but what are some preventive maintenance i should do on it? i'm planning to use this car to go on really long road trips so i don't want it to break down randomly. as far as maintenance history go, engine oil was changed around every 10k miles and not much else was done except for the spark plugs according to the previous owner. btw you are a legend if you reply after 2 month.

[@BenzAddiction]

Check the belt, always have 1 crankshaft sensor handy at least, diagnose and make sure there is no codes on engine and trans. Finally I suggest 5k miles oil change intervals. Good engine have a safe and fun journey.
