So I was driving in Colorado recently and it looks like I've sprung a puncture leak in the core of my radiator. I'm aware that I'm going to have to get the thing recored but I'm about 1000 miles from an auto shop I trust. I've used some heavy duty copper stop leak and that seems to have stopped it. I'm not super keen on this idea but I might have to drive it across Utah on the stop leak. Should I be super freaked out about this?
