Fan Clutch Info

How old is the radiator?

Original radiator, newer hoses, temp sensor, and expansion tank.

I replaced my original leaking fan clutch with a Mahle-Behr part from FCP and noticed an improvement in temps. Now, some say the SACHS is the better part. I will also say, I originally installed my new fan backwards on the new clutch! A forum member caught it in a photo I posted, so, are you sure your fan is installed correctly?

I'm pretty sure...I didn't think I could put it on the wrong way, but I guess anything is possible.

My car was diagnosed as having a bad fan clutch. Car was overheating in stop and go traffic in 90+F temps in central Florida. I ordered a new OE fan clutch made by Mahle-Behr, installed that and a new fan blade and I'm still having the same overheating issues in traffic. Now, I'm being told that sometimes these other "OE" manufacturers aren't as good and the shop is recommending a Genuine BMW OEM fan clutch. I'm reluctant to spend almost $400 for something that may or may not actually fix the issue by going from an the first/original fan clutch to an OE and back to an Genuine OEM fan clutch. Do you have any recommendations for my situation? Thanks in advance!

If the dealer is still supplying original equipment good quality fan clutches, I would say that would be the way to go. Unfortunately I cannot say what they are currently supplying, hoping someone else can. I think that'd be a great data point.

Any updates on this on which is the right part to order as an upgrade from oe/oem?

Bimmerworld might actually be selling 11521737489.

So while this number doesn't directly tie to anything in RealOEM. However, on various different retailers it says its for 5-6-7 series. Which would tie it to 11527502804, which is a 92C version.

Some great info here brother! Do you have a link for the SACHs fan as I would love to order one to try when our weather gets extremely HOT again

As stated, the Sachs are being discontinued unfortunately. So finding a distributor that still has it or NOS on Ebay is the way to go with the Sachs part number.

I believe I might have bought the last one on RockAuto. https://www.rockauto.com/en/moreinfo...t=6812&jsn=472

"When it fails, it can either stay disengaged (causing overheating) or remain fully engaged (causing excessive fan noise and drag)."

A good working efan should prevent the overheat issue even with a disengaged clutch fan.

"Behr fan clutch will engage at around ~93-98C and will shut around at ~85-88.."

I wonder if the stock M3 cfan would engage at lower T than the generic cfan for the non-M cars. These cfans are not totally enaged (locked up) nor completely disengaged. They are always partially engaged proportional to the T on the bi-metal element.
