Zontes 350 Series, ZT350

Coolant capacity & service interval

Zontes 350 Series and ZT350 models require coolant with a capacity of 1.4 liters. The service interval for coolant replacement is 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Zontes 350 Series ZT350-GK, ZT350-T, and ZT350-VX all share an identical cooling system capacity of 1.4 liters, which represents the total fluid volume the cooling system holds during a standard service fill.
  • A 1.4-liter coolant capacity is a relatively modest figure, consistent with the single-cylinder or small-displacement parallel-twin engine configurations typical of 350cc motorcycles, where cooling circuit volume is naturally limited by engine size.
  • The coolant change interval across all three variants is set at 24 months under normal use conditions, meaning the fluid is scheduled for replacement on a time-based cycle rather than a mileage-based one.
  • A 24-month change interval is a common manufacturer specification for ethylene glycol-based coolants, reflecting the rate at which corrosion inhibitors and pH stabilizers within the fluid degrade over time regardless of kilometers traveled.
  • The uniformity of both the 1.4-liter capacity and the 24-month interval across the ZT350-GK, ZT350-T, and ZT350-VX suggests all three variants share the same underlying engine and cooling circuit architecture for the 2023 starting year.
