Hi, I need to replace the heater core on this car. The manual I have (on CD) has hard to see pictures, and I can't really see what's going on. Does anyone have, or know where I can get, a clear step by step procedure on how to do this? Thanks, Dave

Make sure your problem is the heater core - I had poor heating due to malfunctioning water valve (part 15 in this realoem diagram - I chose an April production month for '92, make sure to choose for your own car), and there is an additional water pump as well (part 1) - http://www.realoem.com/bmw/showparts.do?model=HD53&mospid=47404&btnr=64_0114&hg=64&fg=18 The following is one person's fix when, apparently, their heater valve is buzzing - http://bimmer.roadfly.com/5series/messages/archive/msgsy1998w38/4551.html
