Does the car have A/C?  With A/C, it's a bit difficult to install an
electric fan (or at least one that is larger than the one that is already 
there), but without A/C, then it's pretty simple.  I installed
an electric fan and removed the engine driven one (which was not only
the noisy 400mm one, but also chipped) on a non-A/C equipped '73tii.  I used 
the electric auxiliary fan and brackets from a non-A/C 320i.  Requires
that 4 holes be drilled, but otherwise is a very clean installation.
This, BTW, is in front of the radiator.

It works well, keeping the engine temp in check while idling.  If the
car is moving at all, then the fan isn't needed.  My only gripe is
that it's a bit on the noisy side.  The reduction in noise and increased
smoothness is a big plus.

Interesting that Metric Mechanic sells a smaller pump pulley (overdrive).....
Probably not a good idea for any sort of high revving applications.
