2003 540i Coolant Leak
Hi all,
Just replaced the radiator with an OE Mahle/Behr as I thought my previous one either had a small crack on the side or at the drain plug due to some drops from the plug.
I replaced the rad and got a new plug from BMW but it seems like I still have the same drop? Doesn't seem to occur when cold, only after a drive, could there be too much pressure in the system from an overfill maybe and cause it to leak out of the plug or something else entirely?
