I have taken off the fan, and radiator, and ect, and i'm down to this silver circle thing-the fan clutch i believe and black circualr piece that connects to the actual water pump. I need help getting the quot;fan clutchoff. I tried using a wrench and wrenching on this peice between that and the black piece, but i cant stop the black piece from moving. I tried this site called pelican or w.e, but they dont tell u how to do that. I'm stuck, plz help!
Usually there is a notch, slot, or hole in the housing into which you can insert a screw driver or punch to prevent it from turning and then you can use the wrench on the bolts.
You need a viscous cooling fan spanner (32mm) and something to hold the water pump still. The cooling fan has a left hand thread by the way and will need a sharp blow with a rubber mallet to shift it. BMW have special tools for this job which are 11 5 030 and 11 5 040. Viscous cooling fan spanners are available in shops and I dare say you can find or make something to brace the water pump bolts. A large screwdriver or breaker bar have been known to work. Whichever method you use watch your knuckles!
