Additional Notes

  • The Jeep Gladiator JT (EU) 3.0 Diesel carries a cooling system capacity of 13.7 liters, which reflects a full system fill volume typical of larger turbodiesel engines with extended coolant circuit routing.
  • The 240,000 km service interval applies under normal use conditions for the 3.0 Diesel cooling system, placing the Gladiator JT (EU) among vehicles with extended-life coolant schedules rather than conventional shorter-cycle replacements.
  • The 120-month time limit runs alongside the 240,000 km distance threshold for the 3.0 Diesel, meaning whichever limit is reached first governs the coolant change interval under normal use conditions.
  • The 2020-2021 and 2022 onward 3.0 Diesel configurations share an identical cooling system capacity of 13.7 liters and the same 240,000 km / 120-month change interval under normal use conditions, indicating no revision to coolant service specifications between those production periods.
