My take on this is the fact that you said you added coolant. Where I come from, we always mix our coolant half and half with water. I'm not sure if this would trigger a low coolant light though. I would actually myself take it to the shop, and have it flushed, and refilled. and I also do know that there should be an overflow hose somewhere, and that its not a good idea to over fill your coolant. Also make sure that when your adding coolant, your not just adding it to the overflow tank. try checking the level of coolant directally in the radiator. There might be a bad hose between your tank, and radiator. Who knows. Good luck
