Great video lot of learning. Also recently mercedese covered the head of all those 2.0 engines produced in 2021 and 2022 check with your dealer you might qualify for an extended 15 y/150k miles warranty on those heads. I also had the same issue which they covered 100%
Thermostat! The original Thermostat has a wire filter which gets a lot of dirt collected and don't let coolant pass through. You have to replace the Thermostat. The new Thermostat doesn't have that filter in it. So make sure it's off when you get the old one out.
Yes, if the Thermostat hasn't been replace. But once the new one is in, it will last more than the original, due to the elimination of that dirt collector filter
Hei man, really great video, thanks a lot. Btw, my glk 300 v6 also has tapping noise at the passenger side, there is no any tapping at cold start, but as soon as the engine warms up in a few minutes the tapping noise comes up. Is it the same case with your issue in this video or something else? Really appreciate your kind advise before i take any action.
Hey bro, I hope all is well. Answer is no, this engine is for older mercedes like 1991 to 2000. Depending on the year of your GLK, you either have a 272 engine or a 276 engine. Tapping noise at warm up on this engines could be camshaft adjuster, bad oil pump. But I would need a video to hear the noise and from what area
@@nelynel83 thanks bro, It's 2011 GLK 300 (204), M272. engine is good, no burning engine oil, here is the exact same noise that I have: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kEp2iLBMCu4.html
@@nelynel83 thanks a lot bro. I tried to send you video and replied to you, seems the messages are blocked or removed as I don't see my reply. mine is 2011 glk 300 (204) and 272. i don't know how can i send you the video.
You have to take it to the Mercedes-Benz dealer and they will diagnose the vehicle and if they verify that this is your issue. They will give you an estimate if your car is out of warranty, but if it's still under 5 years or 40,000 miles or additional CPO warranty they will repair at no charge.
Hello thank you so much for your help and video very good explanation I am sure this is going to help me out a lot Got a question for you I’m getting this tapping noise from the engine 4.6 L v8 any idea what this is or where is coming from I am digging for air right now but my codes are p0016 / p0017 Please if you got any advice I will really appreciate it
I have a GLB 250 (2021 model and 22k km). The engine check light has turned on. Service said it is because of fuel system. But no exact reason. Then I made them turned the check light off 3 days later it came back on Then 1 week after it turned off by itself. I used the for 200km and full the tank. After 2 weeks light came back again. The average consumption is 17liter / 100 km. Isn’t it too much? What could be the issue?
Why you didn’t send to workshop ? It’s not possible for this head to be fixed in workshop? I have this problem in my car in cylinder 4 also m260 engine, shall I?
Ok cause I was told when you change a part on a gl450 you have to hook the car up to a computer or else it won't go in to gear or work because it wont be able read the new part
@marioarreaga4359 that's no correct. If you're replacing the ISM module which is located on the driver side of the transmission then yes, you need to program and code it. But you are not doing that.
What is the bolt tightening sequence on the m260? I’m in the middle of doing the head on my a35. I’ve seen alot of diagrams online for 4 cyls that show to start from middle of head and work your way outwards. Is this correct for this engine?? Thanks
No timing tool needed. Just set the crank to OT and take cam sensors out to see that intake has a the timing mark facing up, the exhaust will have mark looking like a U
Hey boss, great job. I have a 2021 GLB 250, 31k. Check engine light, took it to the dealership. Burned valve. Asked me for proof of receipts that I changed oil. I am assuming this is the same issue? This is what the dealership will need to do?
@@nelynel83 crazy indeed, made me very disappointed in MB. I purchased this make because of their durability especially with engines. I read that you said once it is changed it is all good, so that’s a relief. What causes this problem? Which part is defective? Also, y r the GLB so jerky when stopping and driving? Thanks mate!
Mainly the valves, intake /exhaust valves. But meecedes so far is changing the complete cylinder head. And about the jerking, if you're talking about while braking, that would be the brake rotors been warped/ burn causes pulsation. If your talking about talking off and while driving that could be the rear differential, we been changing them for this issue also.
@@nelynel83 Nope not while breaking. Like when coming to a slow "almost" stop and then pressing on gas, it like jerks instead of a smooth acceleration. Is that rear differentials as well?
I have 1, I could sell it to you for $50. I could post it on my Ebay account and you can buy it from there. Or you can venmo or zelle and I can ship it to you
Well, sometimes the cylinder head comes with the intake, exhaust valves and valve stem seals in it and head gasket. But sometimes the cylinder head comes naked just the block. I guess it depends on the model. Ask before you order it.
My brother has a 2021 GLB 250 4Matic ... does this car have this type of issue? If so, how many miles will it take to start showing this problem? Will this issue be still under warranty? Thanks.
Yes, this vehicle will eventually have this problem. As long as the car is under the warranty, which is 4 years, 50,000 miles, which ever comes 1st. It will be 100% cover.
@@nelynel83 Believe it or not, he has only 10K miles on it. One more year for the factory warranty. When will this type of issue start happening? Please advise. Some comments below say the warranty is extended to 15 years/150k miles to cover this issue. True?
