32mm wrench and a small hammer always works wonders for me.

There are three common approachs:
1. Use the belt friction to hold the clutch while whacking the 32 mm wrench. (see the Beisan DIY)
2. Use the fan clutch holder tool (~$20) to hold it in place and a 32 mm wrench.
3. Use a screwdriver and wedge it into the clutch to hold it. (This is a cn90 trick)
I find the fan clutch tool works easiest with lowest risk of causing damage. Put a dab of anti-seize on the threads when you reassemble for easier future removal.

This one takes a little bit of finese but it is a great tool. I think I paid around $20 for it.

I tried for what seemed like hours to loosen mine with all sizes of screwdrivers, along with anything else I could think of, with no success. Got the fan clutch tool and it came off in seconds. Facing the car, turn the nut clockwise.

- All you need to know about BMW cooling system overhaul fan clutch nut counterhold tools (1)

For example, this is me using the tool on my M54:


But, others use varying approaches:


I guess the trick is to get enough mechanical force:

People try all sorts of things:


But 'this' is the counterhold tool set to die for!

That has worked for me several times too. I would also add that I hold the pulley with my gloved left hand, and whack the wrench with a hammer with my right hand.

Call around for a shop that will do this for a small fee.

I had this problem in October 2 years ago. the special BMW Clutch Removal tool didn't help me ... I was about to cause some collateral damage or brake/bend a few fan clutch (water pump) bolts.

I drove the car without the cooling fan, going below the speed limit (40 mph) for 4 miles to a shop, waited for 20 minutes, and heard the mechanic working on it for ~60 seconds using some type of air tool. They charged me a cheap $20. Of course, I called them before driving there.
