I have just bought my car used from a dealership in august 2008. A few months after there was something wrong with my starter so when I turned it in they said it was the battery. So I had it changed. This afternoon I couldnt start my car at all but it had been fine this morning. I got someone to jumpstart my car but when I brought it in again they tell my the battery is drained. So far its only been a month and my battery totally drained again. Do you know whats wrong with my car? Oh. And the coolant light has been lighting even if my coolant is on full.
