So did you change the radiator and your refilling the coolant system or just typing off the coolant level? There are no specs on how much coolant it takes to refill the radiator if you replaced it. There is only a total cooling system capacity which does not apply for that.because there is coolant left in your engine hoses heater core etc. I would get two gallons of 50/50 coolant it will probably take At least a gallon and most likely a some of the other gallon as well. If you do not open the other gallon of coolant then you can always return it.
