Yanmar GK

Coolant capacity & service interval

Yanmar GK coolant capacity ranges from 2,9 to 3,3 liters. Service intervals include checks at 10 hours and changes at 1000 hours or 24 months. The data covers 2 configurations.

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

TypeSpecifications
GK160 (2013-2020)

  • Capacity 2,9-3,3 liter
  • Check 10 hours
  • Change 1000 hours/ 24 months
GK200 (2013-2020)
  • Use: Normal
  • Capacity 2,9-3,3 liter
  • Check 10 hours
  • Change 1000 hours/ 24 months

Additional Notes

  • The Yanmar GK160 and GK200 share an identical cooling system capacity range of 2.9 to 3.3 liters, which reflects a service fill volume rather than a full overhaul drain, as the range accounts for residual fluid retained in the system during a standard refill.
  • A 0.4-liter spread between the minimum and maximum capacity figures across both engine variants suggests minor variation in fill level depending on bleeding procedure or system orientation during servicing.
  • The coolant change interval for both the GK160 and GK200 is set at 1,000 hours or 24 months under normal use conditions, with whichever threshold is reached first serving as the service trigger.
  • A separate check interval of 10 hours applies to the cooling system on both variants, indicating that coolant level verification is expected at a much higher frequency than the full fluid exchange.
  • The 24-month calendar limit on coolant changes means that even low-hour equipment reaching the two-year mark under normal use conditions falls within the same replacement schedule as higher-utilization units approaching 1,000 hours.
