Additional Notes

  • Across all three engine variants in the Hyundai Elantra MD/UD (USA) lineup, the cooling system capacity differs by transmission type, with automatic-equipped models holding 5.9 liters and manual-equipped models holding 6.0 liters.
  • The 0.1-liter difference between automatic and manual transmission configurations is consistent across the 1.8 MPI, 2.0 GDI (124 kW), and 2.0 GDI (129 kW) engines, indicating a small but uniform variation tied to transmission type rather than engine displacement or output.
  • Under normal use conditions, the cooling system change interval is set at 30,000 miles or 24 months, whichever comes first, and applies equally to all three engine variants.
  • A separate first-change-only interval of 120,000 miles or 120 months is specified for all three engine variants. In coolant service terminology, a first-change-only interval refers to the extended drain period applicable to the factory-fill coolant before the standard recurring interval takes over.
  • The 120,000-mile or 120-month first-change interval is exactly four times the length of the 30,000-mile or 24-month normal interval, reflecting the extended service life typically associated with long-life factory-fill coolant formulations.
  • The 2.0 GDI engine appears in two distinct output ratings, 124 kW and 129 kW, both covering the 2014-2016 model years. Despite the difference in power output, both share identical cooling system capacities and service intervals.
  • The 1.8 MPI engine covers the full 2011-2016 span, while both 2.0 GDI variants are specified only from 2014-2016, meaning the 1.8 MPI is the sole engine configuration represented in the earlier portion of the model range for this system.
