Product Overview
The water pump circulates coolant through the Mitsubishi S4S engine and heat exchanger/radiator circuit. A leaking shaft seal, noisy bearing or loose shaft can reduce coolant level or circulation and cause the engine to run above normal temperature.
Exact matching listings identify 32A45-00040 on S4S, S4S-61SD, S4S-Y262SD and related S4S industrial configurations. The included gasket and exact pump number make this a more precise match than selecting a pump by engine displacement alone.

Frequently Asked Questions
What are common signs of a failing S4S water pump?
Coolant leakage, bearing noise or play, overheating and visible wobble at the pulley/hub are common signs.
Should the thermostat also be replaced?
Only if testing or service history points to it, but it should be inspected whenever overheating is being diagnosed.
Compatibility can vary by engine, serial number and equipment configuration. Match the original part number and physical configuration whenever possible before ordering.
