I would recommend replacing the radiator if you can afford it. At that age it's probably not worth trying to use stop leak, might be in worse condition than the stop leak can resolve. Could cost more in time to get the car hot, causing major engine damage. One tow would cost as much or more than the radiator. Make sure to flush the cooling system and check hoses.
