Additional Notes

  • The Suzuki Alto cooling system capacity is listed at 3.6 liters across both the 1979-1985 and 1985-1989 model variants, a figure that reflects a total system fill rather than a partial service top-up.
  • The 1979-1985 Alto carries a coolant check interval of every 10,000 km or 6 months under normal use conditions, whichever comes first.
  • A coolant change interval of 40,000 km or 24 months applies to the 1979-1985 Alto under normal use, meaning the fluid is expected to remain serviceable for up to two years before a full replacement is due.
  • The 1985-1989 Alto shares the same 10,000 km or 6-month check interval under normal use conditions as the earlier variant.
  • At 40,000 km or 24 months under normal use, the 1985-1989 Alto coolant change interval mirrors the specification carried by the preceding generation, indicating no revision to the drain-and-refill schedule between the two production periods.
