Your car was running hot and it overheated you pulled it over and got towed to the garage What are the chances your engine is blown only could smell antifreeze?

If you stopped as soon as it overheated, you probably have no damage, unless the head gasket has blown. This would require replacing the head gasket and possibly resurfacing or replacing the head. Depends on why the gasket blew, if it indeed is blown. You may have nothing more than a stuck thermostat, bad water pump, low coolant level, clogged radiator, or a non functioning fan. 29s here, a mechanic once told me that the 2.5 motor could go through hell was gasoline panties on. just dont over fill or deprive it of oil.
