Yamaha XTZ

Coolant capacity & service interval

Yamaha XTZ coolant capacity ranges from 1,2 to 1,7 liters. Service intervals occur every 24000 km 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

  • Change 24000 km/ 24 months
XTZ 750 (1989-1995)
  • Use: Normal
  • Capacity 1,7 liter
  • Change 24000 km/ 24 months

Additional Notes

  • The Yamaha XTZ 660 carries a coolant capacity of 1.2 liters for a full cooling system fill.
  • The XTZ 750 requires a notably larger coolant capacity of 1.7 liters, reflecting the greater displacement and thermal load of the 750cc engine compared to the 660cc unit.
  • Both the XTZ 660 and XTZ 750 share an identical service interval of 24,000 km or 24 months under normal use conditions, whichever comes first.
  • The dual-trigger interval structure, combining a distance threshold of 24,000 km with a time limit of 24 months, means a low-mileage machine still reaches a coolant change point after two years of calendar time under normal use.
  • Both models carry a normal use designation for the cooling system service interval, meaning the 24,000 km / 24-month schedule applies to standard riding conditions rather than a reduced severe-use interval.
