Yup, I have had the same, slow coolant leak for a long time. Tone mentioned a while back it is because of a worn O-ring that is difficult to get at. Mine has been leaking like this for at least 25-30k. I just watch all my fluid levels and wipe up the drips of coolant off the garage floor. See this thread:
