8.4 liters says my repair manual for 6-cylinder engines.
If having one gallon of coolant it would make 45% coolant / 55% water mixture.
If you were in south i would say it's close enough, but in north that antifreeze function is important also.
Can get cracked engine, if coolant isn't strong enough.
