    Water cooled alternator install instructions

    I have 03 745i the alternator locked up have new parts but noticed oil leak at alt bracket I started down the road to replace the $5.00 O ring but have become stuck I don't know if I have drop or remove completely the sub frame. Also I don't want to break open any PS or Trans cooler lines. Is this possible? If so what is the best/shortest method. I have ordered a service manual CD. but don't want to waste any more time I have parts to replace water pump, alternator, all belts, tensioners, and idler pulleys. Also how much/type of Transmission Fluid will I need to acquire in order to change to Transmission filter/pan. It too is leaking and needs to be repaired. thanks for any guidance you could give.
