Kia Opirus / Amanti, GH (EU)

Coolant capacity & service interval

Kia Opirus / Amanti, GH (EU) requires coolant with a capacity of 8,7 liters. Service intervals include checks every 15000 km or 12 months and changes every 45000 km or 36 months. The data covers 2 configurations.

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

TypeSpecifications
Opirus / Amanti 3.8 V6 (2006-2010)
  • Use: Normal
  • Capacity 8,7 liter
  • Check 15000 km/ 12 months
  • Change 45000 km/ 36 months
Opirus / Amanti 3.5 V6 (2003-2008)
  • Use: Normal
  • Capacity 8,7 liter
  • Check 15000 km/ 12 months

Additional Notes

  • The Kia Opirus / Amanti 3.5 V6 and 3.8 V6 share an identical cooling system capacity of 8.7 liters, which represents a full system fill volume including the radiator, engine block passages, and reservoir.
  • Both engine variants specify a check interval of 15,000 km or 12 months under normal use conditions, whichever comes first.
  • The 3.8 V6 (2006-2010) includes a defined coolant change interval of 45,000 km or 36 months under normal use, a specification absent from the 3.5 V6 entry.
  • A 36-month change interval on the 3.8 V6 aligns with the typical service life of conventional ethylene glycol-based coolants, which degrade in pH and corrosion inhibitor effectiveness over time regardless of mileage accumulation.
  • The 3.5 V6 covered model years 2003-2008, while the 3.8 V6 entered the specification range from 2006, meaning a two-year overlap period existed where both engine options were available within the same generation.
  • Despite the difference in displacement between the two V6 engines, the shared 8.7-liter cooling system capacity suggests the engine bay and cooling circuit architecture remained largely consistent across the platform.
