Additional Notes

  • The Mitsubishi Endeavor (USA / CAN) 3.8 2WD cooling system holds 9 liters, a figure that reflects the total fluid volume of the cooling circuit under a standard service fill.
  • The 3.8 4WD configuration carries a slightly larger coolant capacity of 9 to 9.6 liters, compared to the fixed 9-liter figure of the 2WD variant, indicating a modest but measurable difference tied to the drivetrain layout.
  • Under normal use conditions, both the 2WD and 4WD configurations share the same change interval of 30,000 miles or 24 months, whichever comes first.
  • The initial service interval for both configurations is set at 60,000 miles or 48 months, which is double the normal use interval in both mileage and time, reflecting the extended service life of the factory-fill coolant before the first scheduled change.
  • The distinction between normal use and initial service intervals means the cooling system on the Endeavor 3.8 follows a two-phase maintenance schedule, with the first coolant change deferred significantly beyond what subsequent changes would require.
