Product Overview
Circulates engine coolant on compatible Satoh tractors powered by Mitsubishi diesel engines. Proper pump flow protects the cylinder head and engine block from overheating during low-speed, high-load tractor work.
Coolant leakage from the pump area, bearing rumble, fan/pulley wobble or temperature rise under load are typical water-pump symptoms. Inspect the belt and radiator at the same time.
Key Features & Performance

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