Detroit Diesel-style gear-driven fresh water (coolant) pump with cast number 5145089 on the housing. Application: possible fit for Detroit Diesel 71-series V-configuration engines (commonly referenced to 12V71); the exact engine application for this unit has not been verified, and 5145089 is a casting number, not a confirmed orderable OEM service part number.

Cast iron housing in chipped white paint, surface rust on both coolant port lands and inside the bore, blue silicone hose sleeve still on the upper port, drive gear and hub present, temperature sender fitting installed. No rotation, flow, pressure, or leak testing has been performed — recommend reseal and bench check before service use. Drained and ports capped before shipping.
