Daihatsu Sirion 2

Coolant capacity & service interval

Daihatsu Sirion 2 uses coolant with a capacity range of 0,6 to 3,5 liters. The service interval for coolant is 24 months. The data covers 2 configurations.

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

TypeSpecifications
Sirion 2 1.0 12V DVVT (2005-2010)
  • Use: Normal
  • Capacity 3,3 liter
  • Capacity 0,6 liter (Reservoir)
  • Change 24 months
Sirion 2 1.3 16V DVVT (2005-2010)
  • Use: Normal
  • Capacity 3,5 liter
  • Capacity 0,6 liter (Reservoir)
  • Change 24 months

Additional Notes

  • The 1.0 12V DVVT cooling system holds 3.3 liters, while the 1.3 16V DVVT takes 3.5 liters, reflecting the larger displacement engine's greater thermal mass and cooling demand.
  • Both the 1.0 and 1.3 engine variants share an identical reservoir capacity of 0.6 liters, indicating a standardized expansion tank design across the Daihatsu Sirion 2 range for 2005-2010.
  • The 0.6-liter reservoir figure represents the overflow or expansion tank volume, which is separate from the main cooling circuit capacity and accommodates coolant expansion as operating temperature rises.
  • A 24-month change interval applies to both engine variants under normal use conditions, meaning the coolant is replaced on a calendar basis rather than a mileage-driven schedule.
  • The 3.3-liter main circuit capacity on the 1.0 12V DVVT represents the total system fill volume, which is the amount used when performing a full cooling system drain and refill rather than a partial top-up.
