Additional Notes

  • All six manual transaxle configurations in the Hyundai Sonata Y2 (EU) carry a fluid capacity of either 2.5 or 1.8 liters, both of which are typical service fill volumes for a front-wheel-drive manual transaxle unit combining the gearbox and differential in a single housing.
  • The 2.0i 16V (1991-1994) stands apart from the other variants with a notably lower transaxle fluid capacity of 1.8 liters, compared to the 2.5-liter figure shared by the 1.8i, 2.0i, and 2.4i engines across their respective model year ranges.
  • The 1.8i and 2.0i variants produced between 1988-1992 include a fluid check interval at 20,000 km under normal use conditions, in addition to a full change interval of 40,000 km or 24 months, whichever comes first.
  • The 2.4i (1988-1992) follows the same service schedule as the 1.8i and 2.0i from the same period, with a 20,000 km check interval and a 40,000 km or 24-month change interval under normal conditions.
  • For the 1.8i and 2.0i variants from 1992-1994, the change interval was reduced to 30,000 km or 24 months under normal use, tightening the mileage threshold by 10,000 km compared to the earlier 1988-1992 specifications for the same engines.
  • The 2.0i 16V (1991-1994) shares the 30,000 km or 24-month change interval with the later 1.8i and 2.0i variants, though no separate check interval is listed for any of these three configurations.
  • The 24-month time limit appears consistently across all change intervals regardless of engine type or model year range, meaning a calendar-based service trigger applies in parallel with the mileage threshold throughout the entire 1988-1994 production span covered by these specifications.
