Additional Notes

  • The Mitsubishi Montero 3.5 carries a cooling system capacity of 9.5 liters, which is 0.5 liters more than the 3.8 engine that replaced it in the 2000-2006 model years.
  • Both the 3.5 and 3.8 engines share a normal-use coolant change interval of 30,000 miles or 24 months, whichever comes first.
  • The 3.8 engine in the 2000-2006 Montero has an initial service interval of 60,000 miles or 48 months, which is double the standard normal-use interval of 30,000 miles or 24 months listed for the same engine.
  • The 9.5-liter cooling system capacity on the 3.5 engine reflects a full cooling system service fill, meaning the figure accounts for the total fluid volume across the radiator, engine block passages, and reservoir.
  • The 3.8 engine's 9-liter capacity applies consistently across both the normal-use and initial service rows, indicating the physical fill volume does not change between service schedules.
