Nissan Fairlady/300ZX Z32 Coolant Bypass Tube
This OEM coolant bypass tube connector is used on the JDM Fairlady Z and USDM 300ZX to join the engine’s coolant bypass tubes at the front of the engine block. It routes coolant between hard‑pipe sections and ensures balanced circulation through the engine and heater system. Made to factory specifications, it resists corrosion and provides a leak‑free connection where aged OEM tubes often fail. Over time, heat and coolant exposure can cause leaks at this junction, so replacing the connector during cooling system service maintains proper coolant flow, prevents overheating, and supports reliable operation in both naturally aspirated and twin turbo Z32 engines.
- Fits 14053M Location
- USDM 300ZX (Z32): 1990–1996 (VG30DE & VG30DETT – NA or TT)
- JDM Fairlady Z (Z32): 1989–1996 (VG30DE & VG30DETT – NA or TT)
