Cast Iron Dual Thermostat Housing / Water Outlet Manifold - Used, Untested

Cast iron DUAL THERMOSTAT HOUSING / water outlet manifold, twin-bore design with bolted cover flange, upper angled water outlet elbow, second side outlet pipe, cast "VENT" boss and brass vent fitting.

APPLICATION: Not verified. No legible manufacturer name, data tag, or orderable OEM part number is present — only partially legible raised casting marks, which are foundry casting numbers and not service part numbers. The brass vent fitting and copper-salt staining suggest a marine or heat-exchanger-cooled diesel installation, and the twin-thermostat layout is typical of older marine/industrial diesel water manifolds, but no specific engine has been confirmed. Sold by photographs, identifiers, and dimensions. May fit a vintage marine/industrial diesel cooling system; buyer must confirm.

CONDITION: Used, untested take-out. Heavy surface rust and oxidation, scale in the outlet bores, verdigris on one face, old paint remnants. No cracks observed in photos, but the casting has NOT been cleaned, pressure tested, or magnafluxed, and the thermostat elements in the bores are unverified. Recommend cleaning, pressure testing, and new thermostats and gaskets before service.

Item holds coolant and has open ports — it will be drained and all ports capped before shipping.

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

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.
