Additional Notes

  • The Nissan 240SX S14 cooling system holds 6.6 to 6.9 liters of coolant across all listed model years, a range that reflects minor variation in fill level rather than a difference between service fill and full overhaul capacity.
  • For the 1994-1996 240SX, the normal use coolant change interval is set at 30,000 miles or 24 months, whichever comes first, following a time-and-distance dual-limit structure common in factory maintenance schedules.
  • A separate first change only interval of 60,000 miles or 48 months applies to the 1994-1996 configuration, doubling both the mileage and time thresholds relative to the normal use interval for that same period.
  • The 1996-1998 240SX carries the same 30,000-mile or 24-month normal use coolant change interval as the earlier 1994-1996 configuration, with no difference in the service schedule between the two overlapping year ranges.
  • The first change only interval for the 1996-1998 240SX is likewise 60,000 miles or 48 months, matching the extended initial service threshold specified for the 1994-1996 model years.
  • The 6.6 to 6.9 liter capacity figure is consistent across both the 1994-1996 and 1996-1998 configurations, indicating no meaningful change in cooling system volume between the two production periods covered in the specifications.
