Nissan Fairlady/300ZX Z32 Radiator Overflow Cap & Gauge

This Nissan Cap‑Reservoir Tank is a genuine OEM coolant reservoir cap used on the Z32 Nissan 300ZX and its Japanese counterpart. It seals the coolant overflow tank and helps the cooling system maintain proper pressure, which is essential for preventing boil‑over and ensuring efficient heat rejection during operation. This cap isn’t specific to a particular engine type — it’s the same design used whether the Z32 has the naturally aspirated VG30DE or twin‑turbo VG30DETT — because both variants share the same coolant reservoir layout. As such, it fits USDM 300ZX models from 1990–1996 and JDM Fairlady Z (Z32) models from 1989–1996, making it a versatile and correct replacement for maintaining proper coolant system function.
