Mitsubishi 3000GT (USA / CAN)

Coolant capacity & service interval

Mitsubishi 3000GT (USA / CAN) requires coolant with a capacity of 8 liters. Service intervals occur every 30000 miles or 24 months. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Mitsubishi 3000GT (USA / CAN) carries a coolant capacity of 8 liters across all listed trims and model years, from 1990 through 1999.
  • An 8-liter cooling system capacity is relatively substantial for a production sports car of the era, reflecting the thermal demands of a high-output engine layout.
  • The base 3000GT, the SL trim, and the VR-4 trim all share the same 8-liter cooling system capacity, indicating no variation in coolant volume across the trim hierarchy.
  • The 3000GT SL spans the widest documented year range in the specifications, appearing in both a 1990-1996 entry and a 1997-1999 entry, while the base 3000GT appears only from 1997-1999.
  • The VR-4 trim is listed across two overlapping year ranges, 1990-1993 and 1993-1999, which suggests a specification revision or production change occurred at the 1993 model year boundary.
  • All rows carry a normal use condition, meaning the 30,000-mile or 24-month change interval applies to standard operating environments rather than severe-duty cycles such as extreme temperatures or heavy towing.
  • The 24-month time limit on the coolant change interval runs independently of mileage accumulation, so whichever threshold is reached first would govern the service point under normal use conditions.
  • A 30,000-mile coolant change interval was a common industry standard for the 1990s, aligning with the general service cadence of ethylene glycol-based antifreeze formulations used during that period.
