Honda S600 / S800

Coolant capacity & service interval

Honda S600 / S800 coolant specifications cover a capacity of 6 liters. The data includes two configurations for this model.

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

TypeSpecifications
S800 (1966-1970)
  • Use: Normal
  • Capacity 6 liter
S600 (1964-1966)
  • Use: Normal
  • Capacity 6 liter

Additional Notes

  • The Honda S600 and S800 share an identical coolant capacity of 6 liters, despite being distinct engine configurations separated by displacement and production years.
  • A 6-liter cooling system capacity is relatively modest, consistent with the small-displacement, high-revving nature of both engines in the S600 and S800.
  • Both the S600 (1964-1966) and S800 (1966-1970) capacity figures apply under normal use conditions, meaning standard operating environments rather than severe or high-stress driving cycles.
  • The S800's cooling system retains the same 6-liter fill volume as the earlier S600, indicating no significant redesign of the cooling circuit between the two generations despite the displacement increase.
