Komatsu Vibratory rollers, JV

Coolant capacity & service interval

Komatsu Vibratory rollers, JV models require coolant with a capacity of 24 liters. The service interval for the fluid is 6 months. The data covers 3 configurations.

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

Additional Notes

  • All three JV series configurations listed — the JV100A, JV100WA, and JV100WP — share an identical cooling system capacity of 24 liters, indicating a uniform engine cooling architecture across the drum and pneumatic-tire roller variants in the Komatsu Vibratory Rollers JV lineup.
  • The 24-liter figure represents the total cooling system fill volume, which typically accounts for the radiator, engine water jacket, and connecting hoses rather than a partial service top-up quantity.
  • Each of the three configurations carries a coolant change interval of 6 months under normal use conditions, meaning the interval applies to standard operating environments rather than extended-duty or harsh-condition service.
  • The JV100A series begins at serial number 10302, the JV100WA at 20077, and the JV100WP at serial number 30045, with each range representing a distinct production sequence tied to the same 24-liter / 6-month specification set.
  • A 6-month coolant change interval is relatively short compared to extended-life coolant schedules seen in some modern equipment, which can reach 2 years or more, suggesting the specification calls for conventional rather than extended-life coolant formulations.
