Additional Notes

  • The Opel Agila A 1.0 12V produced from 2000-2004 carries a coolant capacity range of 4.3 to 5.0 liters, which reflects a variable fill volume rather than a fixed figure. A range like this typically accounts for differences in how much residual fluid remains in the system during a service drain versus a full overhaul refill.
  • All Twinport variants, both the 1.0 and 1.2 engine sizes, share a fixed capacity figure rather than a range. The 1.0 12V Twinport holds 4.7 liters and the 1.2 16V Twinport holds 5.2 liters, regardless of the model year sub-range within the Twinport period.
  • The 1.2 16V engine fitted to the 2000-2004 Agila A requires 4.9 liters of coolant, which is notably higher than the 4.3-5.0 liter range of the smaller 1.0 12V engine from the same period. The larger displacement engine generally has a greater block volume and a correspondingly larger cooling jacket.
  • Twinport engines introduced from 2004 onward show increased coolant capacities compared to their pre-Twinport counterparts. The 1.0 Twinport holds 4.7 liters versus the earlier variable 4.3-5.0 liter range, and the 1.2 Twinport holds 5.2 liters versus the earlier fixed 4.9 liters.
  • The 2004-2006 Twinport variants, covering both the 1.0 and 1.2 engine sizes, specify a 24-month check interval alongside the 30,000 km distance interval. A 24-month interval is longer than the 12-month interval applied to the other configurations, meaning coolant condition is assessed less frequently on a calendar basis during that specific production window.
  • The 2006-2008 Twinport variants revert to a 12-month check interval, matching the interval used on the pre-Twinport 2000-2004 engines. Despite sharing the same coolant capacities as the 2004-2006 Twinport versions, the later sub-range operates under a more frequent calendar-based inspection schedule.
  • Across all six configurations, the distance-based check interval remains constant at 30,000 km. The only variation in service scheduling between configurations is the calendar interval, which alternates between 12 and 24 months depending on the engine variant and production year.
