Hyundai Stellar (EU)

Coolant capacity & service interval

Hyundai Stellar (EU) requires coolant with a capacity of 6,5 liters. Service intervals consist of 40000 km or 48 months, and 40000 km. The data covers 6 configurations.

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

Additional Notes

  • All six configurations across the 1.4, 1.6, and 2.0 engine variants share an identical cooling system capacity of 6.5 liters, indicating a uniform cooling circuit volume regardless of engine displacement.
  • A 6.5-liter figure for a cooling system fill represents the total capacity of the circuit, including the radiator, engine block passages, heater core, and expansion reservoir, rather than a partial or top-up quantity.
  • The Hyundai Stellar (EU) 1.4 and 1.6 variants produced in 1984-1986 carry a dual-condition coolant change interval of 40,000 km or 48 months, meaning whichever threshold is reached first triggers a change under normal use.
  • The 48-month time limit paired with the 40,000 km distance interval on the 1984-1986 1.4 and 1.6 variants reflects the degradation behavior of coolant additives over time, which can occur independently of mileage accumulation.
  • The 2.0 engine variant across both the 1984-1986 and 1986-1990 periods specifies only a 40,000 km interval with no accompanying time-based limit, in contrast to the dual-condition interval seen on the earlier 1.4 and 1.6 variants.
  • From 1986 onward, the 1.4 and 1.6 variants also drop the 48-month time condition, aligning with the distance-only interval of 40,000 km already applied to the 2.0 across all years.
  • All six configurations are designated under normal use conditions, meaning the stated intervals apply to standard operating environments rather than more demanding or severe duty cycles.
