Additional Notes

  • The Hyundai Elantra GT PD (USA) 1.6 T-GDI carries a cooling system capacity of 6.2 liters, which is a service fill figure representing the total volume the system holds during a standard coolant change.
  • On the 1.6 T-GDI, the normal-use service interval calls for a coolant change every 30,000 miles or 24 months, whichever comes first, applying to both the 2017-2018 and 2018-2020 configurations.
  • A first-change-only interval of 120,000 miles or 120 months is specified for the 1.6 T-GDI, meaning the factory-fill coolant is rated to last significantly longer before the initial drain and refill is required under that condition.
  • The 2.0 GDI engine carries a slightly lower cooling system capacity than the 1.6 T-GDI, with the exact figure depending on transmission pairing: 5.8 liters with an automatic transaxle and 5.9 liters with a manual transaxle.
  • The 0.1-liter difference in coolant capacity between the automatic and manual transaxle variants of the 2.0 GDI reflects minor differences in cooling circuit volume introduced by each transmission type's integration with the engine cooling system.
  • The 2.0 GDI shares the same normal-use change interval as the 1.6 T-GDI, at 30,000 miles or 24 months, across both the 2017-2018 and 2018-2020 model year ranges.
  • Under the first-change-only condition, the 2.0 GDI is also rated at 120,000 miles or 120 months, consistent with the interval specified for the turbocharged 1.6 T-GDI variant.
  • The capacity figures remain unchanged between the 2017-2018 and 2018-2020 entries for both engine types, indicating no revision to cooling system volume across those model year spans.
