Hyundai Sonata, EF (EU)

Manual transmission fluid capacity & service interval

Hyundai Sonata, EF (EU) requires manual transmission fluid with a capacity of 2,1 liters. Service intervals occur every 30000 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
Sonata 2.0i 16V (1998-2005)
  • Use: ->2005
  • Capacity 2,1 liter
  • Change 30000 km/ 24 months
  • Code: 5/1
Sonata 2.4i 16V (1998-2005)
  • Use: Normal
  • Capacity 2,1 liter
  • Change 30000 km/ 24 months
  • Code: 5/1

Additional Notes

  • Both the 2.0i 16V and 2.4i 16V engine configurations share an identical manual transaxle fluid capacity of 2.1 liters, indicating a service fill volume rather than a full overhaul drain, which typically requires additional fluid to account for residual passages and cooler lines.
  • The Hyundai Sonata EF (EU) 2.0i 16V carries a use condition noted as "->2005," meaning the listed 2.1-liter capacity and 30,000 km / 24-month change interval apply through the 2005 model year boundary.
  • The 2.4i 16V configuration specifies a normal use condition tied to the 30,000 km / 24-month change interval, meaning the interval reflects standard operating circumstances rather than a reduced schedule associated with severe or demanding driving conditions.
  • A 30,000 km or 24-month change interval, whichever comes first, applies across both engine variants, meaning time elapsed is treated as an equally valid trigger as distance accumulated for manual transaxle fluid replacement.
  • The 2.1-liter capacity figure is consistent across both the 2.0i and 2.4i variants despite the difference in engine displacement, reflecting that the transaxle unit rather than the engine itself determines fluid volume requirements.
