Ok, I give up. I seem to be adding coolant about every week. About a pint or two is all it takes. The car runs cool, no apparent leaks. I even had it pressure tested! But the low coolant light comes on every week! Checked the oil, no water there either. Is it the start of a head gasket problem? Any ideas or past experience would be appreciated.
