Thanks, for this very descriptive exposé on changing the oil and antifreeze!
If you were to ever update this narrative you might consider adding that the
antifreeze drain bolts are 10 mm (6.5 mm brass washers) and it takes less
than one gallon of 50/50 diluted antifreeze to fill empty radiator system.
I used less than one gallon of distilled water to flush the entire system.
