Application: not verified. Coolers of this type are commonly fitted as marine transmission, engine oil, or hydraulic oil coolers, but no manufacturer name, model, or part number is legible on this unit. Sold by photographs, identifiers, and dimensions only.

Condition: used, untested take-out. Paint is scuffed and chipped with surface rust staining and exposed copper at the brazed seams. The unit has not been pressure-tested, flow-tested, or cleaned, and the internal tube stack and zinc anode have not been inspected. Drained and ports capped before shipping.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.
