My 18 year old was driving on the Interstate. She said that the Sebring lost power, wouldn't go above 55 then she smelled something and saw steam. She pulled over. The car had gotten so hot that the cap on the coolent tank melted. All of the other hoses are fine, there is coolant in the reservoir and water in the radiator. We could see where the water was leaking out, after the radiator, but before the thermostat, the hose was not busted. The car will not turn over, it acts as if the battery is dead, drags when turning the switch. We tested the battery, it is fine, but the car will not start. Would a timing belt cause this?
