We did not replace the oil cooler, it was not disturbed throughout the
entire repair, which is part of the reason for my question. *Of course*
we did ground-run tests after the engine repair, and at 8 hours after
the repair when we replace the mineral oil with Aeroshell 100. No leaks
were present, either time. My question was, SHOULD the oil cooler have
been flushed/pressure tested since a major repair had been done, and/or
how often do mechanics generally recommend that this be done?

When Pacific Oil Coolers returned my after cleaning it out they
included a description of the flush and pressure test they did.
