Additional Notes

  • The Mitsubishi Diamante (USA / CAN) 3.5 carries a coolant system capacity of 9.5 liters, a figure consistent with a full cooling system service fill rather than a partial top-off volume.
  • The 30,000-mile change interval for the 3.5 applies under normal use conditions, meaning standard driving patterns without the added thermal stress associated with severe service classifications.
  • The 24-month time-based interval runs alongside the 30,000-mile mileage interval for the 3.5 across the 1997-2004 model years, so whichever threshold is reached first would govern the service timing.
