Additional Notes

  • The INFINITI JX, L50 cooling system holds 9.6 liters across both the AWD and FWD configurations for the 2012-2013 model years, indicating a uniform system volume regardless of drivetrain layout.
  • Under normal use conditions, the coolant change interval for both AWD and FWD variants is set at 75,000 miles or 60 months, whichever comes first.
  • A separate first-change-only interval of 105,000 miles or 84 months applies to both drivetrain configurations, reflecting a longer service window tied specifically to the initial factory-fill coolant charge.
  • The gap between the normal use interval and the first-change-only interval amounts to 30,000 miles or 24 months, meaning the factory fill is rated to last considerably longer before its first required replacement than subsequent refills.
  • The 9.6-liter capacity figure represents the full cooling system volume, a value typically associated with a complete system drain and refill rather than a partial top-off procedure.
