I was changing the zincs on the heat exchanger, which (as far as I know) only are on the top of the heat exchanger. Since I wanted to drain the heat exchanger as well to be able to open it in order to take a look at the condition of the heat exchanger, I took away one of the bolts on the bottom, but no water or cooling liquid came out. What did come out was this bolt and it looks like there used to be a zinc in there as well. However, since no liquid (water or cooling liquid) I am wondering what the purpose of a zinc would be.
Anyone has an idea what this bolt is for ? It is on the bottom of the heat exchanger and it is the bolt closest to the left side of the heat exchanger. I have searched for a schematic depiction of this heat exchanger, but cannot find it anywhere. The heat exchanger was taken out last year for a pressure test, then the zincs were replaced, but not by me,
