Congrats on what seems like a cleaner radioator & water jackets.
I had a hot engine problem
I am not as handy
anyway my mechanic replaced the radiator
I suppose its best I didn't spend money haveing it flushed
may have been a waste
may have been ok
It seems even w a new radiator
a flush might be in order to clear water jackets
I have some scum on top od the coolant nowe after the radaitor change
anyway guess it just means I have good circulation now & its purging the system
I;d think a flush still could help my system
Anyway may all your efforts be fruitful!
