My fiance's 2017 F150 with the 5.0L is due for a coolant change. It has the old orange coolant which is no longer available so I will use the new recommended yellow coolant. The system holds 15.9 quarts. From everything I have read, a radiator drain only gets out about 1.5 gallons.
If I do a flush where I drain and refill with distilled water and run it up to temp and then keep doing that until what is drained from the radiator is clear, I will end up with more water in the block and other places than I can put back into the radiator so my percentages will be off from 50/50.
What do you guys do in a situation like this?
