Hope you are all out there, it's Sunday and dealership is closed. So it was an easy fix, you can replace the lower hose from top and without jacking car up and getting underneath. Found the leak!!!! It wasn't the hose!!! But I am glad I am replacing it anyway. The leak is coming from the temp sensor. I guess the green o ring has shrunk and failed. I put back together and filled with water and ran to flush the green antifreeze that must have been done from previous owner. I noticed the dripping coming from temp sensor, I wiggled it and I am certain. The problem is, it is Sunday, BMW closed, can I get an oring from local auto store that will fit and thick enough to seal?
