Great video. I have done the fan removal enough times that I can appreciate what a good job you did in showing how it works. A couple of things I want to add: 1) check the bolt to make sure the Allen hex is not damaged, it is possible to install a bolt that if damaged will be very difficult to remove 2) I welded an old 8mm socket that I cut down to some bar stock to make a long handled wrench, it makes the job easier. I practiced off the car with the torque 40 nm or so to get a feel for what it’s like- it isn’t as much as the torque often required to break the bolt free, I think mechanics overdo this bolt and it can make it very difficult for the next guy to remove. Finally this is a great time to change the belt because the fan is so hard to remove, also I remove the belt and check all the pulleys. The bearing behind the fan is often noisy. 5 cars 5 noisy bearings. Also there is an idler bearing that gets noisy. The replacement bolt Mercedes sold me was torx not Allen. The hardware store bolts are a little long but can be cut down. There are stories about how hard a badly damaged it to remove, imagine pulling the condenser and radiator to drill the bolt, I myself have never had to do it anyway. I love the m104, I’m glad I found your channel
Thanks! Helped me alot to change the fsn clutch on w124 m104. Managed to do it without taking off the aux belt. With the right light placement it's possible to see the hole where to insert the special tool without much disassembly.
UPDATE: Had to replace the fan clutch, the KOOLMAN fan clutch I got on Amazon.com didn't work well, it didn't modulate the fan speed. The car turned into a leaf blower, going on the hiway 120km/h I could not hear anything except the fan. Got a URO fan clutch (again from Amazon.com) much better, but not ideal, still noisy to my liking. My suggesion: get a good brand fan clutch.
AndyP Mercedes Channel hi there I changed my fan clutch using you video. Very good by the way. I used a top Mann brand but noticed the fan is rather t load would you say it's brand I used or are you supposed to hear it a bit ? Also how do you check its regulating the speed correctly? Thank you again for your great how to videos.
Based on my experience...yes, the fan will be a bit louder with a new fan clutch. Explanation - the fan pulls more air now since the clutch doesn't slip as much. To gauge how loud the fan is...if you driving on the hiway at 100-110 km/h do you hear the engine noise or just the fan? To tell if it works or not...try to spin the fan while the car is cold and after it wormed up to the operating temperature (after driving 15-20 min) and compare, there's noticable difference. I can't explain it, but looking at both my cars the clutch on cold car will have higher resistance then after it worms up. Eventually after a month or so the fan clutch wears out a bit and the noise comes down.
AndyP Mercedes Channel thank you I will see what's it's like when warm thank you once again other than a bit of fan noise it works great and your tutorial saved me $$$$$$
Thks Mr Andy for the video, my C280 start to do some noise when it's cool, I think that was the problem, but just when its cool, i try to made a video, and maybe we can solve that problem, thks again, greetings from Lima PERÚ. 🇵🇪🇺🇸
OK. Check, there's an air pump on the right hand side of the engine, it turns ON when you start a cold engine and pumps air into exhaust. It runs until the engine gets warmer. It does create some noise, it might be the pump.
It's been a long time since you made the video but maybe it's useful to some viewers. To me that new fan clutch looked way too tight. A brand new behr clutch is quite easy to spin. Just spinning it by hand doesn't really tell you that its bad. The cut in temp for this car should be 102+ degrees if I remember correctly. When it cuts in it literally sounds like a garbage truck and howls like a beast. When not up to temp it just idles silent at max 1000rpm I think it was. Sometimes old and cheap thermostats also don't open fully and people change the clutch out. Thermostat should start opening at 85 degrees and should fully open by the time the fan will cut in. When you have the correct thermostat and the engine is in good condition and the cooling system can get up to a good pressure then you can pretty much drive around with no fan. Only time it really cuts in is 30+ outside temp and city traffic or on big hills maybe. I used to drive a W124 OM603 automatic and it also had an 85 degree thermostat. The clutch was different spec but looked the same. I think the cut in temp was about 97 degrees. The fan almost never came on. But when it did you could hear it very clearly. So basically if you are not happy with your engine temps and it's not extreme weather you should always check your coolant cap and thermostat first. The clutches do go bad but it's certainly not always the first thing to look for.
I would like to ask a question related to the matter. My W202 fan clutch seems to be not working properly, as it feels like it's always spinning the fan 1:1 no matter how hot/cold the engine is. I can hear the noise the fan makes, pulling the air through. But, and that is interesting, the engine coolant temperature, after starting the engine from cold, gets pretty quickly to about 90°C (above 80°C, maybe 85°C) and stays there no matter how fast/slow I drive regardless to the ambient outside temperature. By the temp. readout I can tell the cooling system, the fan included, works fine, but it is a bit annoying to drive a leaf blower around. Or is this completely normal?
In my personal opinion.....i don't think your clutch works correct and i'll explain why i think so. On other hand your thermostat works perfect. If you think the cooling system consists of 4 main elements: engine (hot side), radiator (cold side), thermostat (flow control) and a coolant pump. Your car is "overcooling" the coolant that passes thru radiator and when this "cold" fluid hits the thermostat it causes it to reduce the flow in order to keep the engine at operating temperature. Essentially your car is wasting power to overcool the coolant. This is what I've noticed after i've installed the new clutch on my W202. 1. My W202 also turned into a leaf blower, going on the hiway 120 all i can hear now is the fan (engine is at 3000 rpm). As I can tell it never sounded like that. My S320 that has same engine - i can't even hear the fan at all. 2. I did a comparison with how the clutch works on my S320. The engine temperature is very stable which leads me to believe the cooling system works OK. .....cold engine - i can feel significant resistance on the clutch .....engine at operational temp - the clutch resistance has dropped .....i assume as the engine temp increases, the resistance should increase to keep up. 3. I don't feel any change in the new clutch resistance as the engine heats up. From info I’ve gathered, there’s a max amount of air the fan can pull, this limits fan RPM as the engine RPM goes up. This rpm limit is built into the fan clutch; it’s the slip in the clutch (or clutch resistance). So if the clutch resistance has changed the amount of air it can pull in will change. From what I can see there are 2 failure modes: clutch has lost the resistance therefore the engine overheats in stop-n-go traffic and clutch is stuck, essentially becoming a rigid element and robbing power from the engine. It feels like you have a second failure. The clutch I got is a KOOLMAN fan clutch from Amazon, I will be returning it. I got another clutch made by Uro, should be here in few days. Hope Uro clutch works as should..
I think so. For what ots worth... 50$ and 1/2 hr of your time I'd stay away from the KOOLMAN clutch, the one i have didn't work. Check Pelican Parts, FCP or Autohaus AZ, I've bought parts from them before and it seems they sell OK staff, at least I recognise the manufacturer names, like Uro, Febi etc
AndyP Mercedes Channel I already had a poke around and found a Febi Bilstein clutch for only about $42. Sachs for about $50 and we can go up to $180-$190 for the top notch stuff. I'm gonna go with Sachs, as I used their products before. I live in Europe, so I can get all the parts quite cheap. Now, I just have to find a spanner big enough, to actually take the clutch off. On the M111 engines, the clutch is actually the nut and you screw it on the pulley.
Yea..Sachs is a good brand, I think its OEM cause the original clutch that i pulled off is Sachs, I can tell its original it has a stamp 95, same as my car year. One thing...at Rockauto.com i've seen some clutches listed as thermal and other non-thermal. Pay attension when buying. www.aa1car.com/library/cooling_fan_clutch.htm Im not sure, the nut might be 32mm. Good luck. Let me know if new clutch will fix your issue.
Hi Mr. Andrew; today I need some help, we’ll remember the noise from my C280, well that coming from the Fan Pulley, I change the belt a few months ago, and change the alternator, but the noise persists, the question is...

I think i'll get the correct thermostat and will replace, it's only 23$.
You know, it's an interesting question, I don't know.. It might be that for different markets MB would install different thermostats. I know that I enter my serial number into the parts book and the thermostat PN comes out and it indicates 87degC. Why would MB indicate this unless there are other options available, but since my car was made for Canada part book shows only one option. I can't imagine that a car shipped to middle east or Africa would have same cooling system heat rejection capacity as the one made for Canada.
