I was instructed to fill my coolant tank with 50/50 coolant. Me not being a car guy, I FILLED it.. full. Is it going to be alright? Or do I need to find a way to get some of the coolant out of there so that its not well above the "Cold Fill" line.
 
Most coolant tanks are actually expansion tanks and often the cap isn't a pressure relief type. I suspect that you should get that level at least in the vicinity of the cold fill mark or you may be leaving tell tail puddles every where that you park for a short time.
 
Most of the time cars have an overflow so if you overfill it the excess with drain out.
