1990 320i bmw. Filled up the coolant overflow tank with 750 mils (filled up to cold level line when engine was cold) about 2 weeks (220 kilometers ago). Drove 20 or 40 k's that night and about 500 or so mils had disapeared when I checked it in the morning. 190 kilometers later the rest of the 250 remianing mils of coolant has disapeared. Car has new radiator. Car only smokes white smoke out the exhaust when engine is cold and when the engine was COLD a few days ago there was water coming out of exhaust tip. I cant see any leaks around the radiator pipes. I cannot see any evidence of water in the oil.
