Coolant capacity & service interval

Toro Professional mowers use coolant with a capacity of 7,5 liters. Service intervals include checks every 10 hours and changes every 24 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The CT2240 (serial 314000001 and up) and LT3340 (serial 313000001 and up) both carry a cooling system capacity of 7.5 liters, which represents the total system volume including the engine block, hoses, and reservoir.
  • A check interval of 10 hours applies to both configurations under normal use conditions, reflecting how frequently coolant level and condition are to be inspected during regular operation.
  • The change interval for both cooling systems is set at 24 months under normal use, meaning the drain-and-refill cycle is time-based rather than hour-based for scheduled replacement.
  • The identical 7.5-liter capacity across the CT2240 and LT3340 suggests a shared or closely related cooling circuit design between the two Toro Professional mower configurations.
