So the thread title says it all. I need a new fan clutch for my M110 280SL. New Behr or Sachs which I am inclined to trust are just astronomical so unless I get lucky and find one at a super deep discount, I'm looking at the rest of the market. Some like URO I will not buy, but hope there is some recent experience on the board for other aftermarket suppliers.

Thanks!

Finding a good fan clutch seems to be a real touch and go thing. I would think they could build a consistently reliable unit, but apparently not. Many do not work correctly right out of the box and then a noticeable number only work for a few months. Sad point is they all look about the same on the outside. Leaks are common. Weird. In general, I tend to stay away from Meyle (many complaints and I also had a Meyle on a W113 that was dead and leaking on arrival) and Uro as well as any odd branded units. Factory MBZ, Behr (there are some Chinese made Behr's which have been touchy), and Febi are probably more likely to work out.

I was fortunate to be given a brand new clutch for my car. Just checked and it is still in original Mercedes box. Clutch itself say Richter & Sachs so presumably Sachs were the OE supplier.

And here I was thinking Meyle might be a suitable choice...!

Behr from M-B or even any of the go-to discount OEM suppliers is just silly- $750 - $1000 USD! I simply don't understand this when a Behr clutch for virtually anything else is $200 or much less.

Every fan clutch i've ever purchased has been around $30. Considering how easy it is to bolt and unbolt, I don't mind being cheap here.

For my recent fan clutch purchase, I bought one on Ebay for around the price I mentioned before. Probably Uro and MTC, either way, if you go this route I have a heads up for you. When I got mine, I was worried the clutch itself wasn't working right. Turns out, if they're stored improperly they won't clutch out and just keep spinning.

This manifests itself as a continuous roar at high speeds and the engine sort of acts funny because the whole thing is battling it out with the fan and airspeed. Hard to explain until you have it happen.

Eventually, the gel inside the clutch will start to work as it moves out into the right places. Mine did this and now cuts out properly.

Ive been suspicious of the clutch in my 84, as the temp has been a little higher than I would expect- No problems, but around 90 - 95c rather than the 80 - 90 it usually would be. Checking the clutch the other day, and I detected a very slight wobble- there should be none. I can't risk that big aluminum fan coming up through my freshly repainted hood, so time for a new one.

I just like to use good quality parts, and it really galls me that for a stupid fan clutch on a 6 cylinder M-B the price for Behr or Sachs is so out of line with everything else. At least I now have all winter to track one down.

There is an aftermarket one for sale on Ebay for $29. Item number 271903187116. It is made by Topaz and is marked Germany for what it's worth. The part number is 000 200 04 22. I contacted seller (GermanPartsSaver) with my VIN and confirmed it to be correct for 107 280SL. There are other Topaz manufactured fan clutches for sale on Amazon but not this PN. All reviews were good but limited in number. I ordered one today. Will see what it looks like when it arrives.

I'll try to post a link to it.

Considering mine is 34 years old and has 210,000+ miles on it....I'd say that is pretty reliable.

OEM:)

Ahh but it's the consistency part-!

I agree with the 30+ years old part, hard to complain about that. But my OE Behr unit only has 70k miles on it and it's failure mode could really do some damage to the car.

I prefer OE as well, but Nobby, $750 for a fan clutch??:eek

Thanks for the heads up on this Don- Never heard of Topaz, hard to believe it's made in the fatherland! I'll look into it, let me know what you think hen you get yours.

Thanks!

Interestingly, (t me, anyway) is that this clutch is the same one that fits most of the old 4 and 5 cylinder diesels. It's not like it's a low production piece. Why the ridiculous price for a name brand?

The part number is only same for up to 617 engine 39531 (about 79?) After that those engines had part 0002001922 . At OE Discount $232 instead of about $765 for earlier one. Some of the aftermarket clutches claim to fit many models. Could be just a difference in fan bolt layout or something????

I noticed that a number of the on-line vendors offer Meyle. They probably wouldn't do that if they had a lot of returns. Most of the cheap units are probably made in same shop in China and just sold under different names. Uro, Koolman, etc Meyle & Febi probably also from China, but maybe with some quality control?

Saw this on a European site. Don't know if current, but perhaps OE are a bit cheaper there?

Clutch radiator fan

A0002000422 (355 EUR)
MEYLE 0140200050 (118 EUR)
FEBI 18142 (112 EUR)
DASIS 128050N (39 EUR)

BTW, doing this research partly for myself! Just in case I need a clutch for my W123 one of these days (440k km so far)

Did you get the clutch yet? Any initial observations?

Thanks!

For the V8 equipped cars they are cheap. For the M110 6, not so much.
Chief I don't have a dog in this hunt but here's a couple of thoughts.

Will the V8 fan clutch fit the M110? Or adapted?

Also have you considered doing away with the fan clutch altogether and adding a fan/relay setup? Definitely cheaper, readily available and they do work well IF you don't overload the alternator. A friend of mine tried a dual fan setup on his 560SEC. It worked great up until the point the alternator said "F%#K THIS"...:laugh He switched to a single fan setup with no problems...

Just some thoughts...

Don't really have a way to determine if a V8 or later I6 clutch will work, no way to compare short of having them in hand to measure or trial fit. Not really interested in using electric fans, I like keeping everything stock under the hood. But who knows, I guarantee I won't spend ridiculous money on what should be a $50 part!

Not urgent at this point, now that winter is settling in. Gives me a little time to figure it out.

Just to close the loop, I found a Meyle that is at least labeled Made in Germany, for $70. Less than 10% of what a Behr is available for!

I did receive the aftermarket fan clutch. It arrived in just a couple of days. There are no markings on it of any kind. It is identical in every appearance to the OEM Behr. There are no finish flaws. I doubt if it is German made. I am not sure my original clutch is bad. It tests out OK but the engine still wants to run a little over 100 at idle in hot weather traffic so the fan clutch is the only thing I haven't tried. The new clutch is a little stiffer to spin than my old one so maybe it will help. I have installed it but I am doing other work on my car and I haven't driven it on the road yet and the weather is cool. I have run it quite a bit in my shop though. It "sounds" like it is moving more air at idle than the original one so perhaps the old one was a little weak. I will have to see as far as longevity.
