I am having trouble finding a way to remove the fan because the gap between the pulley bolts and the fan is too narrow to allow off-the-shelf tools to fit. I have tried a large el cheapo adjustable wrench, and a Craftsman 32 mm metric open ended wrench, unsuccessfully (luckily, I walked back into Sears and got a refund when I tried their tool out in the car park -- I know I know, I could have asked for a refund even if it fit! Those suckers ain't cheap -- $25.99+ tax ouch). On my old 1990 e34 I could get the adjustable wrench in there, but on this 1991 model the gap appears to be slightly less, for some reason. Any advice, besides delegating the job of swapping out belts to my regular mechanic?
