Hey guys anyone know whats different between the water pump found in a 02' X5 and the pump found in our 02' 745?? The part numbers are all over the map and some sellers say one pump fits all N62's with the water cooled alternator wether it be for an X5 or 540.. Or do you know what changed between the 02' pump and the late 03'? Thanks in advance for any help.

Well after doing my water pump I can see what the difference would be and it has to do with the water cooled alternator. On the bottom of the pump there is a small gauge water pipe going from the alt housing to the pump odiously not need ed on a car without a water cooled alt. Thought I would share just incase other were wondering.
