| | Testing a water pump
I've been having a leaking problem somewhere from the coolant container to the radiator and I can't figure out where the hell its coming from. I've tested just about everything I can think of, except the water pump and the radiator plug. I have no idea how to test a water pump though. So could someone give me a quick crash-course in water pump testing on a '92 325i?
Any help is greatly appreciated.
