Engine Coolant Water Pump Assembly With 3-Groove Pulley, Likely Caterpillar - Used, Untested

Belt-driven engine coolant / water pump assembly with cast-iron open-face impeller and three-groove V-belt drive pulley.

Application: Not verified. Styling, paint and construction are consistent with the Caterpillar belt-driven water pump family (reverse-image hints suggest the 3208 / 1160-3160-3204 group), but no legible manufacturer tag, casting number, or OEM part number appears in the photographs. May fit Caterpillar industrial or marine diesel applications; buyer must confirm. Sold by photographs, identifiers, and dimensions.

Condition: Used take-off, untested. Heavy surface rust and scale on the impeller, chipped paint, oily residue at the seal area, and light flange corrosion. No flow, pressure, or leak testing has been performed — treat as an untested unit or rebuildable core. Coolant passages will be drained and open faces protected before shipping.

The only marking readable on the part is a hand-written "15/16" on the pulley face, which is a shop marking and not an orderable part number.

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.
