Does anyone have any good ideas for removing the fan? My '88 535i has the single, large nut (24mm I believe)holding the fan to the water pump. Yesterday, I lost the fan belt & I'm trying to install the new one today. I can't get the new belt past the fan without damaging the radiator, and I can't get the pulley to stop spinning when I try to loosen the nut (reverse thread, correct?)in order to remove the fan. If anyone has any tips, I sure could use them right about now.
