Radiator leak in '01 e53 X5
Hello all! My '01 e53 X5 has a coolant leak. I've removed the shroud below and the airbox/snorkel above and all the hoses seem to be in working order. Also, the radiator is barely a year old (new installation spring '12). My research leads me to believe it is a separation between plastic and aluminum somewhere internal, but a 1 year old radiator shouldn't have that problem yet right? Can anyone tell me if there are more diagnostic techniques I might employ to sort out this issue? I shudder to imagine buying a new radiator at this juncture. Help!!!
