No - you still need a pulley to drive the pump regardless of the fan you use. PCD's need to match.
There are, from my experience 3 different pulley sizes. The Centre hole changes diameter, and there are 3 PCD sizes. There are 2 common pumps, the third, as far as I can tell, appears to only be on the KE1x's
The location of the pulley on the shaft also varies, so you need to make sure your fan belt is in line with your crank pulley.
I think (but not certain) that the issue with heater hoses is mainly to do with the thermostat mount, not the water pump. Different versions of this have heater hoses coming out in various spots, as well as emissions gear.
