Thanks for clarifying. My original inquiry was about doing a flush with Barnacle Buster as I am on a mooring without any way to have a fresh water flush set up.
I am now convinced that I need to service the after cooler. Is this done by just removing the end caps or does the after cooler need to be removed from the engine.?
In Tony’s last reply it shows the heat exchanger what is the suggested maintenance for it?

So is the solution to not remove and service the after cooler as suggested and go ahead with the planned Barnacle Buster flush?

Thanks for the reply. I was planning to have the after cooler serviced next season. Can that be done on the QSB 6.7 without removing from the engine?
