Product Overview
Coolant leaking from the pump weep hole, bearing growl, pulley wobble, or overheating with poor circulation can indicate water-pump failure. Belts, radiator airflow, thermostat, cap, hoses, fan, coolant level, and head-gasket condition should be checked too.
The belt-driven pump circulates coolant through the engine and radiator. It cannot correct a plugged radiator or trapped air, and a misaligned belt can quickly damage the new bearing.
Match the engine model and serial number, pump casting, hub and pulley offset, bolt pattern, hose connections, gasket, and original references. Several Deere engines use similar-looking pumps.

Frequently Asked Questions
Q: Can a water pump fail without leaking? A: Yes. An impeller can be damaged or a bearing can fail before an obvious leak appears.
Q: Does the pulley come installed? A: Only the components shown are included; compare the product photos and reuse specified hardware.
Q: Will it fit every John Deere 328? A: No. Match engine, serial number, casting, hub offset, and original pump number.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
