My Cummins coolers go to a radiator shop for pressure testing and
cleaning every 3 years, so I had always wondered how my
heat exchanger for the Seakeeper Gyro
heat exchanger was doing. I ended up
buying a second heat exchanger that I put on, and will swap it out with the original every few years.
Overall, the tubes looked good, no blockage. I am going to cut new end cap gaskets and clean this one up.
So my question, what would you suggest to clean the internals of the
raw water tube bundle?
-I was thinking of CLR?
-CLR dilution?
-How long should the solution stay inside?
Any other ideas welcome.

BTW, I realize I could have pulled the end caps and checked it, but there are other reasons why I bought a new one and they are not very $, well in
boating terms that is.
