Muito util, obrigada e parabens❤
Showed this video to my severely autistic pet pigeon and he changed my water pump while I was asleep. That’s how good this video is.
Haha, that's funny!! Thanks for your comment, and thanks for watching : )
This video should be a model of how a repair video should be put out there. I can't thank you enough for your time to put this together. I'm fairly confident a wrench but please know that you still made my life so much easier. Thank you.
My ! My ! My! Wow! Wow! Wow! This was a SUPERB video in EVERY possible respect. Clarity of explanation, instructions of caution; clarity of video recording, no shortcuts everything was fully demonstrated, provision of torque specifications in different units, ( which is what I have been searching for from last night without success but finally found it here this morning). You can be very proud of your effort here. I am most impressed and especially so if this was done by a woman (It sounds like , forgive if I'm wrong) in this a man's dominate world from automobiles were invented. I must subscribe to your channel . Thank you ! Thank you !
Thank you - I appreciate your comment! Yes, I'm a woman, and yes, I will always include torque values whenever I can on my video!
Thank you for watching! : )
As always an OUTSTANDING, detailed instructional repair video. Absolutely the best on UA-cam BRAVO !
Thanks! And thanks for watching! : )
Wow, this is the best repair video I have ever watched on UA-cam. I don't typically comment but your video was just amazing. I look forward to more of your work in the future.
Thank you so much for taking the time to comment, and thanks for watching! : )
Holy cow, this video is next level, huge props and gratitude!
Thanks, and thanks for watching! : )
I just did the water pump on my 1999 ml 320. I watched your video several times and followed your procedure to the letter. VERY VERY helpful, your attention to detail had a very positive outcome for me. Mine had the rubber gasket. I was quite nervous about the gasket slipping, fortunately it didn't. The hour of cleaning made quite a difference in the way the gasket fit. Thank you for all the work you put into your videos.
Wow, that's outstanding!! Yes - cleaning that gasket surface is very important, and it always takes me a long time too!
Thanks for adding your note about the gasket difference with the '99 ML320 - and thanks for watching, and great job on your DIY! : )
@@L35inColorado You are my go to when it comes to my ML repairs. My ML seems to be following slightly behind the repairs you do. At 210,000 miles it has exceeded my expectations for reliability. next project is transmission fluid. plug and filter, transfer case fluid and front and rear differential fluid change. The transmission drain plug looks very angry so wish me luck.
OUTSTANDING VIDEO INSTRUCTIONS. IM a big fan just enjoying your tutorial. NOt everyone does work with this kind of care and thoroughness. I do almost the same as what you do with tape, markings, cardboards for the bolts and all print out of torque specs.
Really fun watching. I have a 113 engine on an S430 so this was good just to watch your technique
THANK YOU FOR MAKING THE VIDEO. This is a lot of work, videoing and explaining and also adding parts number in the edits. WOW. Wished all videos were like yours.
Wow, thanks for your comment! Yeah, I like details too : ) Thanks for watching and for sharing your tips on your S430!
I followed your instructions to the letter. You by far have the best video for the water pump replacement. Thank you. I have a 2002 CL500 and it works perfectly
Outstanding!! Great job on your DIY : )
Thanks for watching!
Absolutely the best video for this repair. GREAT!
Thank you, and thanks for watching! : )
Snap! Best auto repair video ever. Thank You!
Great video! I’ve used the cardboard trick for many years to keep varied length bolts organized. I have to do this to my 2001 E430 soon as I noticed some wobble in the fan/water pump and my tensioner pulley was starting to chirp on a 1000 mile trip in the latest Christmas arctic blast. I had never noticed any coolant leaks but an inspection of the frame showed a little coolant residue. Thankfully it warmed up by the time we drove back and it made it home without issue but I ordered a new pump and all of the pulleys and a new belt just to freshen things up. I am still amazed at how robust these cars were made and even with something on its way out, it still got us and the dog there and back without being stranded in the cold on the side of the road. I love the old car even more now and will replace any other parts that I find questionable and this video gave me a few tips to help make the job easier. Thank you!
Wow, that's a great story! I agree that these M112 and M113 engines were gems from MB - they are robust indeed. Thanks for watching, and Merry Christmas & Happy New Year! : )
A brilliant video that was so helpful. Just had to change my pump in a car park with minimal tools, thanks to the detail provided here (particularly tool sizes, as I had to buy the sizes I needed). As an additional note, I changed mine without dropping the radiator fan shroud, as the two bottom bolts on the shroud were corroded to round stubs, and I didn't have tools to remove them. It is just possible to get the pump out, but the edge of the shroud took the skin off my arm, so remove/drop the shroud if you can. Also, regarding pump failure, mine never leaked, but the rear bearing collapsed in a few minutes of running. Sounded like the engine was destroying itself, with pump pulley wobbling +/-5mm. Stopped the engine immediately and changed the pump where it stood aa a collapse like this can damage the pump back plate (timing chain cover?), which becomes a much bigger repair. Luckily, mine ate the pump body only, such that the pulley moved out 5mm. My pump was original and had done 450,000km.
Brilliant.! Thanks. 😊 I’m so looking forward to doing it tho…seized pump this morning, belt cooked, destroyed the idler/ tensioner puller… oh the joys.
Ah, I'm sorry that happened! But I'm glad the video helps - good luck, and thanks for watching! : )
Thankyou ! 😊
Same thing happened to me! So grateful for this video
You do an excellent job every time.
Thank you, and thanks for watching! : )
I have to say I am so glad I found your channel I have a 2002 ML320 and so far you have everything I needed to do to it I am a mechanic as well but you make it so easy for me with torque and all and yes I am a torque mechanic lol if you know what I mean I see a lot of mechanics just tighten bolts I came from working on jet engines and prop engines to car now turbines lol so to me torque is very important and cleaning thank you for doing all of that❤
Buenas tardes desde Venezuela. Me quedo sorprendido de la capacidad del Señor para explicar con lujo de detalles la reparación. No existe mezquindad en impartir conocimiento ni en el uso de los recursos audiovisuales para transmitir sus conocimientos. Mil gracias.
Acá en Venezuela en muy difícil conseguir ayuda y soporte para mantener nosotros mismos nuestros vehículos. Gracias nuevamente. Cualquier información que pueda suministrar se lo agradecería. Mi vehículo es MB ML 320 1998. W163. Gracias por siempre y que tenga una vida larga y productiva.
Your detailed step by step instructions were spot on! Got me thru changing my water pump without a problem. Thank you! I plan to keep my 2004 ML350 as long as possible, so pls keep up the awesome videos.
Nice - well done on your DIY! Thanks for watching! : )
I can't thank you enough for your super detailed videos. I did the water pump on my 2008 ML550 (W164 with M273 engine) a few weeks ago, and am getting ready to replace the pump on my 2006 ML500 (W164 with M113) this Saturday. I went with a Graf pump for the M273 and got the Meyle for the M113. Outstanding work ! 🙂
Wow, you've been busy! Great work on your DIY's, and I'm glad you like the videos. I think you made a good choice getting the Meyle for M113. Thanks for watching! : )
Just say WOW! Really well done videos! Loving it!
Thank you! : )

hello madam, I am a new subscriber to your youtube channel that I like! indeed I have an ML320, and I liked your working method on the detachment of parts to change and others! thank you and good to you, from Gabon.
Wow! Thank you for being a subscriber, and thanks for watching - all the way from Gabon! : )
@@L35inColorado hello madam, lately I encountered two problems on my ML320 V6:
the first, following my wife's negligence to drain the gearbox, me not being there, the vehicle started to jerk when going from first gear to second, I do the oil change and cleaned the box but nothing has changed, in my research I had as information that it was necessary to change the gearbox plate, if you could advise me on this point please!
The second point is the boot error which has already happened to me twice, I am currently redoing the reprogramming of the key, if not the chip. if you could also give me the causes of this problem, otherwise I have the option of paying my ''ML Quick Start v 2.0'' to reprogram my chips, otherwise correct the error. thank you for answering me, good for you!
Very well explained,
Thank you, and thanks for watching! : )
Hello dear operator of l35 Colorado channel, I write to you from Germany, "home of the stars" that sometimes cause us worries and problems, but in the end we love them, maybe because we know that there is rarely better... I do not comment much but I wanted to tell you that your posts are among the best do it yourself channels I know. I have already learned a lot from you and so have been able to fix problems on my Alabama Trash Can through your informative and detailed videos.
I would be interested to know if you have already been affected by problems with the well known "AAM". If I could wish for something, then just by you a tutorial or explanatory video to remove, open, examine this cursed AAM control unit, which sometimes ensures that our MLs also wake up at night without ignition key to life. Also a tutorial on a professional Xentry diagnostic procedure would be great. Maybe you read this and now you also know that you have fans in good old Germany :) all the best for you and please forgive possible spelling mistakes.
I'm sorry I missed your comment! I am aware of the AAM and all the trouble it can cause, unfortunately. I am not familiar enough with the AAM to contribute much to the conversation, but I have learned a lot from reading the forums here:
www.google.com/search?client=opera&q=site%3Awww.benzworld.org+w163+aam&sourceid=opera&ie=UTF-8&oe=UTF-8
That is a site search of www.benzworld.org for the term "AAM". I hope one of those posts might help you! : )
Good teacher
Thank you, and thanks for watching! : )
I concur with you about the GRAF brand waterpump. I bought one for my R350 and was so disappointed, I trashed it and ordered a Mercedes OE from the dealer along with returning the core. The quality is much better to do Mercedes Original
Yes - the MB's are the way to go. It's too bad, because the GRAF's used to be practically indistinguishable from the MB's. I'm not sure what happened!
Thanks for watching and for sharing your tip, too : )
bravo. very detailed!
Thank you! And thanks for watching : )
Excellent -- so thurough.

@@leone390987 Thanks! : )
insane video
Thanks for watching! : )
Awesome video as always! The attention to detail in your videos has made intimidating jobs much more approachable and less stressful :) Did you use any threadlocker for any of the fasteners? Some of them look like they might have had some remnants of blue threadlocker
No, I did not use any threadlock. Sometimes I do find threadlock on that long E14 alternator mounting bolt, but there are no notes in the WIS regarding the use of threadlock on any of those bolts. I hope that helps - thanks for watching! : )
@@L35inColorado got it, thank you!
I’m planning on tackling this job next weekend and had one more question. Would you recommend cleaning the sealing surface on the water pump and the engine with brake parts cleaner? It seems like it’d be a good way to remove the residue from the gasket remover
@@Charbley Yes, that's fine - I used a little brake cleaner on a shop towel after cleaning up the Permatex to get the surface residue-free.
(I just noticed that I put "Permatex 86045" on the video, but the correct number is "80645". I do recommend having that on hand, if you can!)
Depending on how easily your gasket comes off, you might be able to get everything cleaned up with brake cleaner alone (in my case here, that didn't work, but I have done these pumps in the past without so much trouble cleaning the surface).
If you have some brake cleaner, gasket remover, and some scrapers on hand, you'll be able to get it clean - though expect that it could possibly take a lot longer than you'd think! As mentioned in the video, just don't use any brushes/tools/scrapers that will create scratchess in the aluminum.
I hope that helps - good luck! : )
@@L35inColorado Awesome, thanks for the in depth response! This will be my first water pump job but I’m fairly confident that it’ll go (relatively) smoothly thanks to your tips and super thorough video. Thanks again!
You are great of teaching. Thank you
Thank you! And thanks for watching : )
1. Love the channel so far! EXCELLENT videos. Question though. W163 V6. Ihave the needed tools but the clutch nut wont budge. To boot, it is rounding. I do have the appropriate wrench. Thx to my local parts store loaner that is how i started down the road of the nut rounding off. ANY ideas as im really in need of fixing this..Not sure if i can at this point.
Ah man - that's so frustrating, and I have been there too. If you haven't reviewed this video, I show some options - if you're not using a pulley holder, you will need to do that, and possibly add a shim between the wrench and the nut, if the nut is rounding/rounded:
ua-cam.com/video/Ols8w3zSTMM/v-deo.html
If you have access to an air hammer, this kit might be the solution, because impact is highly effective in getting that nut to budge:
www.harborfreight.com/pneumatic-fan-clutch-wrench-set-58526.html
Those are my best tips, as far as tools - something to hold the pulley well, and something to impact that nut. Be sure you're turning in the correct direction (especially if you're using the air hammer kit). There's always the (last) option of cutting (but hopefully you don't need to go there!). I hope that helps! : )
Thx so much for the reply. I have the holder. May have to go to air. Or maybe heat.
I think there should be a way to replace just a bearing on water pump and leave the old casing. I would not trust that Graf water pump. It does not look quality made. The content is as always great. Great job.
You know, I still have the old MB pump - I might try that as a little experiment! The housing is aluminium and the bearing is steel, so I bet I can slip that bearing out with some heat on the aluminum. If I do that, I'll make a video.
As I mentioned in the video, I was quite disappointed with the Graf pump out of the box - I have never, ever had any issues with Graf before. But also as I mentioned in the video, I emailed Graf pictures, and they confirmed that it is indeed theirs. It has only been a few thousand miles since the repair (it's my sister's ML), and there haven't been any issues - bu I'll certainly update, if needed.
I have noticed now on some webpages that this "new" Graf style (as seen in the video) is showing in pictures (compared to their old style, which looked identical to MB). Here's an example:

Thanks for your comment and suggestion about the bearing, and thanks for watching! : )
@@L35inColorado Thanks for the reply. I have 2003 ml350 almost 6 years already. 125k miles, never had any issues with thermostat or water pump, but you never know what is in future :). So I am watching all of videos very carefully and gaining theoretical experience :), although I have already changed breathing hoses and valve cover gaskets on both sides.
Weird I have a 2007 V6 ML350 and it has the oil cooler.
I just ordered a new water pump so hopefully it is the correct one lol.
You can check your part numbers at FCP Euro (for example, and other sites) - but this video is for the first generation of the ML engines (M112/M113). Your '07 ML350 has a different engine than the M112/M113 shown in the video.
Here's what FCP Euro shows as the water pump for an '07 ML350:

Please be sure to double-check that, because I'm not familiar with the '07 ML350 engine. But I hope that helps : ) Thanks for watching!
@@L35inColorado Yes I ordered one here in Canada from a place in Ontario. Should be here next week. After replacing the intake manifold myself on my V6 this looks to be a heck of a lot easier lol. Cheers for the reply.
Hi L35 Do you have to remove the thermostat housing to remove the water pump? or can it be removed leaving it in place. Thanks for the great video awesome as alway's.
No, you don't need to remove the thermostat - you can work around it. The thermostat is often replaced during this job simply because you have to drain the coolant to replace the water pump, so people often swap in a new thermostat while everything is empty. I hope that helps! Thanks for watching : )
Great, thanks for the info, I was told the thermostat was replaced around 6 months ago, shame they didn't do the water pump too! 🙄
I've watched 6 videos on the Idler pulley for the M113 and I've got multiple different torque values. 25 Nm, 20 Nm, 35 Nm, gut feeling Nm. What the actual hell? Why is this idler pulley torque value SO difficult to figure out?
I'm not sure about the other values, but the value I posted is from what's in the Mercedes WIS (MB's factory service manual program).
What application is your M113 - year/model?
Hi :)
You are fantastic... Your videos help me a lot for my ml500 :) I have one question... in this video you show one pictures from anonym book at 24:50... can you tell me what is this book or where can i ordered this ? Thanks and i wish the best for you!
I'm sorry I missed your comment! The pictures shown at 24:50 are from the Mercedes WIS, or Workshop Information System. You can buy access to the WIS through a few different means, but it is VERY expensive! I got the information shown from the www.benzworld.org forum. There are some very helpful MB techs on that forum who post tips, WIS info, and lots of other great stuff. For example, here's a page on the water pump replacement that includes some WIS pdfs (this is just for an example - the particular WIS page shown might be out-of-date or NA):
www.benzworld.org/attachments/w210_water_pump-pdf.162963/
that's from this thread:
www.benzworld.org/threads/diy-water-pump-wis.1362156/
That forum is one of the best places to find WIS info. I hope that helps - good luck! : )
So, the alternator bolt is stuck, like galled. I can do two quare turns in, two guater turns and a tiny but out, I'm not going to live long enough to get it out, what to do?
So I got it out, had no anti-sieze or anything, after midnight, found some sliding door silicon lube and without any regard for future belt slippage problems I might cause, or whatever, sprayed some in, half a turn in, half a turn out, then straight out all trhe way without more than little severe force.
Came out with last 1.5cm of thread encased in galled aluminium, so not sure what was going on, I suspect I should have made more effort on cleaning it than a quick wire brush before putting it back in (I already had the bolt out, fit the new pump, put it back in, but f*cked up the gasket and was taking it back out second time to redo the gasket).
I will comment again if there is silicon consequences, but I think not.
I'm so sorry I missed your comment! But I'm so glad you were able to work it out, and especially that you shared you tips!
How do you know you need to change the water pump ?
It's a good question - in this case, I noticed that the pulley was slightly wobbling, which is typically caused by failed bearings. When the bearings fail, coolant will usually (not always, but usually) leak past the bearings, and you'll see the residue shown at 38:36. If you see that, the water pump needs to be replaced.
Another reason people change the water pump is if they find metal shavings in the coolant, which is a sign that the pump internals have failed.
I think also people replace the water pump at about 150K miles as a preventative measure, since they often replace the thermostat preventatively at that time, and they have the coolant drained, so they just replace the water pump while in there.
I hope that helps! Thanks for watching : )
I would buy that book (phisically) what you use from 51:30 .... Can you send me link or address,name where can i buy taht ? Thanks a lot
That image is from the Mercedes WIS (Workshop Information System), which I don't think is available in print. I think it is only available online, on CD-ROM, or through the MB subscription service. If you check the forums (such as www.benzworld.org) you can sometimes find pages from the WIS posted by forum members who have access to the WIS. That is how I got those pages. I hope that helps - good luck! : )

Mercedes design is even more idiotic, and even the fan is driven by an engine.
Mercedes is garbage , What a bad design this car is,only see bunch of different screwdrivers and screws, you know this car is garbage.
Yes, it is often required to have specialized tools to work on MB's. Personally, I prefer 4-cylinder Toyota engines, but I will say that these MB M112 and M113 engines are actually pretty reliable and easy to work on, especially when compared to other "performance" engines. So - it is what it is! Thanks for watching : )
