6bta Aftercooler core

[larman]

Pulled out my starboard after cooler disassembled and the core literally slid right out. Anyway I’m concerned with the core. I have had the boat for three years and this is the first time I have serviced this unit. Let me know what you think.

Clean it up and put it back on. Aside from a few bent fins, looks good.

Great info here about servicing your after coolers. See details about greasing it for easy removal next time. Since you don't know the history and the fact it has visible damage I would have it pressure tested. If it fails you might have to rebuild the engine so fairly cheap and more peace of mind.https://www.sbmar.com/tonys-tips/

Yes have read all of that. I was shocked that it just slid out with my hand. No tools needed.

Well, the PO must have serviced it at some fairly recent time. Mine took 13 tons of pressure to get the core out of the housing. My PO never serviced it. I would clean it up and reassemble it. Then pressure test it and make sure it will hold about 25PSI or so overnight. If it doesn’t hold pressure try reassembling it and retest. If it still doesn’t hold pressure it may be bad.
