Mercedes-Benz Cast Iron Coolant Water Pump Impeller - Used

Mercedes-Benz Cast Iron Coolant Water Pump Impeller — Used, Untested

Application: Cast iron backward-curved vane impeller for a diesel engine coolant / circulation pump. The reverse face carries cast 'MERCEDES-BENZ' lettering and the cast number 3522010207. The 352-prefix marking points to a possible Mercedes-Benz OM352-family coolant pump application; the exact application has NOT been verified and this number is a casting mark, not a confirmed orderable service part number.

Condition: Used, untested take-off. Cast iron with dark oxidized surface, light surface rust and scale in the vane pockets, and minor wear/handling marks on the vane tips. No visible cracks in the photographs; the part has not been crack-tested, measured, or balance-checked. Sold exactly as pictured — impeller only, no shaft, bearing, seal, housing, or hardware.

Approximate size: roughly 4.25–4.75 in impeller diameter, about 1.75–2.0 in tall (estimated from photos).

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.
