Plate-type oil cooler / heat exchanger core, removed from service.

Application: Oil-to-coolant cooler of the type used on medium and heavy-duty diesel engines and on transmission/hydraulic circuits.

Condition: Used, untested take-off. Plate stack appears complete and undamaged with no crushed or torn plates visible. Surface rust on the cast port elbows and mounting bosses, staining and residual paint on the top cover. Not cleaned, not flow tested, not pressure tested. Core only — no O-rings, gaskets, housing, brackets, or hardware included. Internal condition and leak integrity unknown; we recommend cleaning and pressure testing prior to installation.

Approximate size: 12 in x 6 in x 5 in core, roughly 8–9 in tall over the port elbows. Drained and ports capped for shipping.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.
