I have a 98 328I with 233k miles. A few months ago the car overheated, replaced the thermostat, nothing, replaced the head gasket and the little hose on top that goes into the nipple of the radiator was glued and zip tied. Had to constantly every 2 days fill the antifreeze reservoir with coolant as it would empty. Other day the little hose that was glued popped off causing the car to over heat. Replaced the radiator same problem is occurring. Not overheating but coolant is emptying out. We put 3 gallons of coolant in today after replacing the radiator and tested it for at least an hour if not more. Drove a mile reservoir nearly emptied. Filled drove 40 miles home, coolant empty again? I'm being told perhaps the gasket was improperly replace--just 3 months ago...Thoughts?
