pushing the e30 kinda hard, and it started to smell funny. then the engine coolant light on the check panel lit up so i took the next exit and pulled over to check it out. found some spray under the hood, around the radiator/coolant hoses but couldn't pinpoint the leak in the dark. i drove to the nearest gas station and bought a gallon of coolant, figuring worst case scenario i just keep pulling over and topping her off on my way home. at the gas station i noticed the coolant was leaking out of the radiator. filled up the reservoir and started driving. every time i noticed the coolant light, i would pull over and top her off again. it happened every five miles until the last ten or so miles. the coolant light didn't come on again that drive, and when i checked the reservoir, it was full. i parked her for the night and when i woke up this morning checked under the car for a puddle, drips, etc BUT there weren't any. i drove my car to my parents' house (25 or so miles) with no problem. no leaks, no lights, and the heat works fine. also, no bad smells coming from the vents. i think it was just her having a mechanical period. i'm not that concerned with it but its fuckin weird, so tell me mechanical geniuses of GC, what the fuck happened?
