Most european cars have plastic water pump impellers. It is so when they fail you don't have a big chink of metal floating around your cooling system. Also if a bolt breaks on the pump housing the pump won't grind away the block ruining the entire motor. I have changed probably 20 BWM water pumps and they all had plastic impellers.Originally Posted by sjettav
