Additional Notes

  • The Dodge Hornet 1.3 PHEV carries two separate coolant capacities depending on which circuit is being serviced. The main cooling system holds 5.6 liters, while a combined fill covering both the cooling system and the high voltage system brings the total to 7 liters.
  • The 7-liter figure for the 1.3 PHEV reflects the additional thermal management circuit dedicated to the high voltage battery and associated hybrid components, which require their own coolant volume separate from the internal combustion engine circuit.
  • The Hornet 2.0 also splits into two circuits. The primary cooling system holds 6.6 liters, and a secondary low temperature circuit carries an additional 2.2 liters, bringing the combined system total to 8.8 liters across both loops.
  • A low temperature circuit, as seen on the 2.0 engine, typically manages charge air cooling or other heat exchangers that operate at lower thermal thresholds than the main engine coolant loop, which is why a separate capacity figure is listed.
  • Across all four rows, the change interval is identical at 150,000 miles or 120 months under normal use conditions. 120 months equals 10 years, placing all listed configurations on a long-life coolant service schedule.
  • The 1.3 PHEV specifications begin with the 2023 model year, while the 2.0 specifications begin with the 2022 model year, meaning the 2.0 engine predates the PHEV variant in the Hornet lineup by one model year.
