While the radiator and main hoses are generally near the front of the car, that is only a part of the car's cooling system.Included in that system are the heater lines and heater core. Look for smaller diameter hoses (about 3/4 to an inch in diameter) leading back to the firewall of your car, and inspect them for leaks.Hope this helps!
