no no no. people are just going at this the wrong way. stop. breathe. relax. no need to beat on anything. this is not a brute force job. be calculated and careful how you position your tools.
you'll need two things:
long screwdriver (heavier duty the better) and a 32mm sears wrench (sears seems to be the only place that sells/offers this)
position 32mm wrench. position screw driver blade in between two of the water pump nuts.
now just hold the nuts as you push the fan nut the other way (clockwise)
just push. no bang, no beat. if stubborn you can soak nut in penetrating oil prior.
banging on things is just going to cause problems especially if not careful.
I'll be doing this this weekend on my friends M3. maybe i'll make a video
