Radiator kills the water pump
We have a 2010 e60 with a N52k.
Any owner removing the radiator for any reason, pulls out the radiator and the bottom 33% of the radiator is blocked from leaves and dirt. When the radiator is pulled there is a massive amount of leaves that come out with it.
If the bottom 33% of the radiator is blocked, is it logical to think the electric water pump now has to work 33% harder to cool the engine?
If the electric water pump is overworked, is this the key reason that the majority of BMW electric water pumps fail prematurely?

The pumps are designed to handle coolant at the temperatures that are present. The area of the radiator does not affect the performance of the pump but the temperature of the coolant. When the area is not large enough to cool the coolant sufficiently, then the temperature rises, but not higher than the design temperature of the pump. The pump will, however, be pumping at maximum flow, but the pumps are designed for that too. Non electric pumps always run at max flow and the temperature is controlled by bypassing the radiator. I believe that the electric pump motors are probably under sized electrically and suffer electrical failure because of that.
