Additional Notes
- The Hyundai Sonata EF (EU) 2.0i 16V and 2.4i 16V share an identical cooling system capacity of 5.5 liters, which represents the total system fill volume including the radiator, engine block passages, and reservoir.
- The 2.7i V6 carries a noticeably larger cooling system capacity of 7 liters, reflecting the greater coolant volume demands of a six-cylinder engine compared to the four-cylinder variants.
- Both the 2.0i 16V and 2.4i 16V specify a change interval of 45,000 km or 36 months under normal use conditions, meaning whichever threshold is reached first triggers a coolant replacement.
- The 2.7i V6 specifies only a 36-month change interval under normal use conditions, with no distance-based threshold listed alongside the time-based figure.
- The time-based component of the interval, 36 months, is consistent across all three engine variants, indicating a shared maximum service life of three years regardless of engine displacement.
- A 5.5-liter cooling system capacity, as seen in the four-cylinder variants, is a moderate figure for inline four-cylinder engines of the late 1990s and early 2000s, consistent with engines in the 2.0 to 2.4-liter displacement range.
- The 2.7i V6 entered the specification range starting in 2001, while the 2.0i 16V and 2.4i 16V cover the full 1998-2005 span of the EF generation in the EU market.
