I have two Yanmar 6LYA2-STPs. I'm in the process of cleaning my raw water cooling system. Before I flush with Rydlyme, I'm taking apart the aftercoolers and cleaning / greasing / o-ring replacement. I've read that I should pressure test them, but I haven't found any good description of what that entails.
What I'm thinking of doing is to reassemble the aftercooler. Plug the raw water outlet. Pressurize (via raw water inlet) to about 20-25psi. Then submerge the entire aftercooler in to water and look for bubbles out of the air side of the system.
Does this sound ok? Am I missing something?
Thanks!
