citrus flush causes all this hard white chalk in my cooling system?
good evening,
i am replacing my coolant pump that failed in the midst of a citrus flush. most concerning to me is that the pump is covered in white chalky deposits. the monovalve was also clogged with this stuff. just caked on.
its not citric acid powder - it must be a precipitate or byproduct of the citric flush.
anyone experience this? or is this normal and what the flush is cleaning out?
i put in food grade pure citric acid, and followed the same steps as posted here a while back. im perplexed.
many thanks,
dd
