If one of your radiator hoses is cold, it is a sign that your thermostat is not opening and allowing coolant to flow past it into the radiator. "Stronger" antifreeze will do nothing but change the boiling point of the coolant. Since your thermostat was changed, I would check that it is functioning and that it was put in in the correct direction (if it is backwards, it will not open properly).
