Buyer's checklist
What to check before buying a used water pump
- Spin the pump pulley flange by hand to check for smooth bearing operation, grinding noise, or shaft play (a new pump is usually recommended due to low cost).
- Inspect the weep hole on the pump body for blue/green coolant residue, crusty mineral buildup, or active leakage signs.
- Check impeller vanes (plastic vs stamped steel vs cast iron) for corrosion, missing fins, or detachment from the shaft.
- Verify housing bolt patterns, thermostat housing integration, and belt pulley hub offset relative to engine accessory drives.
