Additional Notes
- The Nissan 300 ZX (EU) coolant system spans two distinct chassis generations, the Z31 and the Z32, each carrying different capacity figures despite sharing the same service interval structure.
- Both the Z31 300 ZX and the Z31 300 ZX Turbo carry an 11-liter cooling system capacity, indicating a larger total system volume consistent with the engine bay layout of that chassis generation.
- The Z32 300 ZX Twin Turbo holds a 10-liter cooling system capacity, one liter less than the Z31-based configurations, reflecting a difference in system volume between the two chassis designs.
- All three configurations share an identical service interval of 40,000 km or 48 months under normal use conditions, meaning the drain-and-refill schedule does not vary between the turbocharged Z31, the naturally aspirated Z31, or the Twin Turbo Z32.
- The 48-month time limit on the coolant change interval is significant because coolant degrades chemically over time regardless of mileage, so the calendar threshold can trigger a service before the distance figure is reached.
- The Z31 300 ZX Turbo covers model years 1984-1990, while the naturally aspirated Z31 300 ZX covers 1984-1989, meaning the turbocharged variant continued one additional year within the Z31 production run according to the specifications.
- The Z32 300 ZX Twin Turbo entry spans 1990-1991, overlapping with the final year of the Z31 Turbo in 1990, indicating both chassis configurations were present in the specifications simultaneously during that year.
