Marine Diesel Aftercooler / Charge Air Cooler Assembly - Used

Used marine diesel aftercooler (charge air cooler) assembly removed from a marine engine. Cast housing with integral finned core, two large cylindrical air ports, an open air flange, and small raw-water/vent stubs. Application: not verified — visually consistent with a Cummins marine aftercooler family (QSM11 / QSC style); a Volvo Penta D-series charge air cooler cannot be ruled out. No data plate or legible OEM number was found, so no part number is claimed. Condition: used take-off, untested. Exterior soiling, dirt, and paint chipping consistent with engine-room removal; internal tube-bundle condition and seawater-side corrosion are unknown and not warranted. Recommended to be pressure-tested and serviced/re-cored by a qualified shop before use, and best considered a rebuildable core. Unit will be drained and ports capped before shipping. Estimated shipping weight approximately 40 lb; approximate size 24 x 12 x 11 in. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
