My Hyundai Elantra 2004 car with 65000 miles started showing engine malfunction, I drove it for another 5-7 miles to see local mechanic. It stopped later on and I restarted again and after half miles it stopped. The mechanic after seeing it....said I overheated the car and engine is locked now because of heat and lack of coolant. after checking it he says I need to change the engine and radiator to run the car. I dont understand many technical terms, but I'm really wondering is that is there no solution at all?......Is there is a chance that a mechanic with better experience and knowledge can solve this problem......???
