TGB Bellavita

Coolant capacity & service interval

TGB Bellavita coolant capacity ranges from 0,55 to 0,65 liters. Service intervals occur every 12000 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
Bellavita 125i (2012-2018)
  • Use: Normal
  • Capacity 0,65 liter (Radiator)
  • Capacity 0,55 liter (Reservoir)
  • Change 12000 km/ 24 months
Bellavita 300i (2012-2019)
  • Use: Normal
  • Capacity 0,65 liter (Radiator)
  • Capacity 0,55 liter (Reservoir)
  • Change 12000 km/ 24 months

Additional Notes

  • The TGB Bellavita carries a split coolant capacity across two separate volumes: 0.65 liter for the radiator and 0.55 liter for the reservoir, bringing the total system fill to 1.20 liters.
  • The radiator capacity of 0.65 liter reflects the active cooling circuit, while the 0.55-liter reservoir holds the overflow and expansion volume that cycles in and out as the engine reaches operating temperature.
  • Both the 125i (2012-2018) and the 300i (2012-2019) share identical radiator and reservoir capacities, meaning the cooling system volume does not differ between the two engine displacements.
  • The coolant change interval is set at 12,000 km or 24 months under normal use conditions, whichever comes first, applying equally to both the 125i and 300i variants.
  • A 24-month time limit alongside the 12,000 km distance interval reflects the chemical degradation of coolant additives over time, which occurs regardless of mileage accumulation.
