When driving on the highway for a short road trip the engine warning light and bell came on saying that the engine was overheating. Pulled over on the side of the road and popped the hood to find the radiator wet and smelling sweet. I limped the car the few miles and had the car towed to the local dealership. The dealer ship stated that the radiator fan was loose causing the blade to rub a whole in the radiator causing a hole to form. They also replaced the oil in the car to ensure that the oil was not compromised after getting so hot. Replaced with havoline synthetic.
