This OEM coolant bypass hose is used on the JDM Fairlady Z and USDM 300ZX to connect the heater core to the thermostat center engine water pipe in early Z32 models. Made from heat-resistant, flexible material, it helps direct coolant flow during engine warm-up and supports proper thermostat operation. Over time, hoses can crack or swell from heat and coolant exposure, so replacement is recommended during cooling system maintenance. Using the correct early-year hose ensures proper fit, leak-free connections, and reliable engine temperature control for both naturally aspirated and twin turbo Z32 engines.
