Hello gents, It is my understanding that the cooling system capacity is 32 quarts or 8 gallons. I drained the radiator, pulled the two block plugs left and right, flushed the whole system with a hose. When adding the 50/50 coolant, it took 6.5 gallons or about 26 quarts. Is this normal or did I not get it all out? I ran the heater as well thinking that might help. The truck is a 1965 2500 Panel. Thanks in advance.
