Vessel Name: S.S. Short End - 2005 Sabre 42 Express
Engines: Cummins 8.3 QSC 490hp x2
Location: Seattle, WA
Country: USA
Hey everyone, I have twin 2005 QSC 8.3 engines on my 2005 Sabre 42 Express and I’m doing the aftercooler maintenance on them. One of the cores has some bent vanes that may have happened before or during transport home to my shop to clean. Doesn’t look that bad but wanted to know if I should just leave as is or try to do something about it. Leaving for a 3 week trip to The Broughtons Archipelago in BC Canada on 8/2/23 so hoping to get this resolved before we leave.
Also, other than removing the end caps for the heat exchanger, replacing the gaskets and cleaning out the visible areas, is there anything else I should be doing for heat exchanger maintenance?
Thanks in advance! Willie

I would not worry about those air fins but a pressure test would probably make you sleep better.
As long as the heat exchanger is clean and not starting to get a coating / clogging of the arteries you should be good to go.
