Hyundai Bayon, BC3 (EU)

Clutch fluid capacity & service interval

Hyundai Bayon, BC3 (EU) clutch fluid capacity ranges from 0,36 to 0,8 liter. Service intervals include checks every 15000 km or 12 months and changes every 30000 km or 24 months. The data covers 4 configurations.

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

Additional Notes

  • The Hyundai Bayon BC3 (EU) 1.0 T-GDI carries a clutch fluid capacity of 0.36-0.42 liter, which is a relatively small reservoir volume consistent with a compact hydraulic clutch actuation circuit rather than a full overhaul fill.
  • The 1.2 MPi variant, covering model years 2020-2023, specifies a noticeably larger clutch fluid capacity of 0.7-0.8 liter compared to the 1.0 T-GDI, indicating a meaningfully different hydraulic circuit volume between the two engine configurations.
  • Both 48V-Hybrid variants of the 1.0 T-GDI engine do not carry a stated numeric capacity figure. Instead, the specification references a fill level between the minimum and maximum marks on the reservoir, meaning the service procedure relies on visual level inspection rather than a measured volume.
  • All four configurations share an identical check interval of every 15,000 km or 12 months, whichever comes first, under normal use conditions.
  • The fluid change interval across all listed configurations is set at 30,000 km or 24 months under normal use, meaning a full drain and refill is due at twice the frequency of a routine level check.
  • The 1.0 T-GDI (88 kW) 48V-Hybrid covers model years 2020-2024, while the 74 kW 48V-Hybrid variant shares the same starting year of 2020, and both carry identical service intervals and reservoir-level-based fill specifications.
  • All configurations across the Bayon BC3 (EU) lineup are noted as hydraulic clutch systems, meaning the clutch actuation is fluid-operated rather than cable-operated, which is why periodic fluid condition and level maintenance is specified.
