You have told us so little about your car and your problem, i have no answers, just questions. What “little hole” are you talking about? Under what conditions does the car overheat? Has this just happened or has it been running hot for a while? Is the check engine light on? Has the engine been loosing coolant before this. What engine and how many miles? Answer everything I asked, and I’ll try and help further. ---

If you can’t answer Mustangmans’ questions, I suggest you have it towed to a mechanic. If you have not been servicing the cooling system on schedule, do not be surprised if you need a new radiator along with thermostat and hoses. ---

Running hot can ruin an engine. Can you drive it to a good mechanic without another overheating incident? The symptoms are consistent with a leaking head gasket: combustion gasses overpressurize the cooling system. It could be something less serious. Hope for that, but prepare for a new head gasket or a new or used engine. Good luck and please let us know. ---
