Hyundai Trajet, FO (EU)

Coolant capacity & service interval

Hyundai Trajet, FO (EU) coolant capacity ranges from 6 to 9,4 liters. Service intervals include checks every 15000 km or 12 months, and changes every 30000 km or 24 months, or every 36 months. The data covers 6 configurations.

Additional Notes

  • The two diesel variants of the Hyundai Trajet FO, the 2.0 CRDi 16V in both 83 kW and 92 kW outputs, share an identical cooling system capacity of 9.4 liters, which is notably higher than the petrol engines in the same model range. A larger coolant volume in a diesel application is consistent with the greater thermal load diesel combustion places on the cooling circuit.
  • Both CRDi diesel variants carry a time-based change interval of 36 months under normal use conditions, with no distance-based interval specified. A purely time-based interval reflects the degradation of coolant additives over time regardless of mileage accumulated.
  • The 2.0 CVVT variants, available in 103 kW and 104 kW outputs from 2004-2008, specify a capacity range of 6-7 liters rather than a fixed value. A stated range typically accounts for variation introduced by residual fluid retained in the system during a service fill versus a full drain.
  • The CVVT petrol engines carry a two-stage service schedule under normal use: a check interval at 15,000 km or 12 months, followed by a full coolant change at 30,000 km or 24 months. The check interval allows for top-up and condition assessment without a complete fluid replacement.
  • The 2.0i 16V, covering the 2000-2004 period, specifies a fixed 7-liter capacity and a 36-month change interval. The fixed capacity figure, as opposed to the range given for the CVVT engines, suggests a more straightforward drain-and-fill procedure with less system variability.
  • The 2.7i 24V, spanning 2000-2008, also specifies 7 liters and a 36-month change interval, matching the 2.0i 16V in both capacity and service timing despite the larger six-cylinder displacement. Equal coolant volumes across different engine sizes can reflect differences in block design, circuit routing, and reservoir sizing rather than displacement alone.
  • Across the petrol engines, the 2.0i 16V and 2.7i 24V share the 36-month time-based interval used by the diesel variants, while the CVVT engines use a shorter 24-month change cycle paired with an intermediate check. The 24-month interval on the CVVT engines represents a more frequent replacement schedule relative to the other petrol and diesel entries in the range.
