I never fill the radiator with what I think is 50% of the capacity with coolant. If you think it is 9 gallons, get 9 gallon milk jugs and fill each with a 50/50 mixture. Then start filling the radiator with them. If the actual capacity is 7...you still have a 50/50 mixture in the radiator. If the actual capacity is 11, keep making gallons of 50/50 until it is full. What ever you have left, which isn't much, carry as extra in case you need it, and the radiator has exacty a 50/50 mixture.
Sorry if I made this confusing. The bottom line is that if you don't really know how much coolant it will take, even though you may know the capacity as stated in the manual, this is a good way to insure your radiator is full and you have it full with a 50/50 mixture. The other way is do it one gallon at a time...make a 50/50 mixture, put it in the radiator and keep doing that until it is full.
This avoids situations where the manual says your capacity is 9 gallons, so you drain it and add 4 1/2 gallons of undiluted coolant. Then you fill it with water, but the radiator is full at 3 gallons of water. Now you have a mess which is a pain to get to the correct 50/50 mix, BTDT.
