My Low Coolant light came on this morning, checked it out, and the reserve was pretty much empty, so i filled it back up. I checked the oil, and it's clean. There haven't been any leaks or puddles that i've noticed. I just got this car, so it's possible that it could've just been low. Are they any other possible things to look out for if there was a cause to drain it? Or does the radiator fluid just get used up over time? thanks.
