Product Overview

Circulates coolant through compatible small Yanmar industrial diesel engines used in compact equipment. The engine model is the strongest starting point because John Deere and Komatsu used multiple Yanmar engines across similar machine families.

Overheating, coolant seepage around the pump body, noisy bearings or visible shaft play are typical reasons to replace a water pump. A clogged radiator or failed thermostat can create the same overheating complaint.

Key Features & Performance

  • Restores coolant circulation through the engine and radiator.
  • Addresses leakage, bearing wear and reduced coolant-flow concerns.
  • Model/engine and hub or bolt-pattern checks help avoid similar-looking pump mismatches.
