Don't worry the 0.46 quarts left must be in the bottom of the radiator and your hoses (upper left one) and since you ran it with distilled water u probably have a mix 1.9 coolant + 0.46 water (which is ok) or a lil less (Air).
PS: Next time run the engine over 100°C to fully clean the...
Did u really flush the entire cooling sys (including the hoses)? if not... that's why.
U also need to run ur engine over 100°c to open the thermorstat and let the coolant running through the whole radiator... then u'll need to refill the reservoir. (same for air bleeding... u'll have to refill...
Main issue, to me, if u have any problem/leak u can't add water... pretty annoying if u are unlucky on a road trip.
They don't recommend more than 3% of water in a cooling sys filled with their coolant.
Not funny....at all... but why people are so... stupid... sometimes.
