Additional Notes

  • The Yanmar YT118, YT120, and YT122 each share an identical cooling system capacity of 1.8 liters, which represents the total service fill volume for the cooling circuit.
  • A 10-hour check interval applies across all three models, meaning coolant level inspection is scheduled at a very early stage of operation relative to most other fluid service points.
  • The coolant change interval is set at 24 months for the YT118, YT120, and YT122, making the replacement schedule time-based rather than hour-based.
  • The uniform 1.8-liter capacity across the YT118, YT120, and YT122 suggests the three models share the same engine cooling circuit architecture despite carrying different model designations.
