Water pumps help your engine keep from overheating by circulating water around a sort of " water jacket " surrounding the motor. This is due to BMW using an electric water pump in their cars rather than a traditional mechanical water pump. maximum pump working pressure ∆pWater Pump Failure One of the most common problems that BMW owners encounter is water pump failure. Criterial quantities providing the wear symptoms identification of tested pumps, were separated during the pump characteristics empirically obtained analysis. Relation of the occurring failure states and observed symptoms The gear pump failure states, that occurred most often, were identified in chapter 3.
