My Ride: Old fart E46 sedan
You should consider investing in a pressure pump so you can do a pressure test whenever you do a work on the radiator. E46s are vulnerable when it comes to fluid leaks, at least in my experience. I have replaced the expansion tank 3 times, the whole hose assembly once, even the cover thingy at the back of the engine and the water pump too. Have you replaced the oil and tranny cooler? You dont want the coolant or tranny fluid to go inside the engine
