Randomly my titan will over heat and dump all of the damn coolant out, and this only happens when I'm sitting still not driving around. And it seemed to start doing this right when I re charged my ac. Not sure if that has any connections with this. I know the radiator has to keep a certain pressure and also in the over flow, is that a common thing that if it getting too much pressure it dumps all the coolant out? But that doesn't make any sense to me cause it only happens when I'm sitting still. I've looked for cracks and leaks and there are none. Probably a pressure problem somewhere just don't know where or how?? Advice and feed back will be helpful thanks guys
