A complete fan shroud system is essential for directing airflow and maintaining cooling efficiency on the Z32 platform. The genuine Nissan Lower Fan Shroud (part number 21477-40P00) is the factory lower section that attaches to the upper radiator shroud and surrounds the cooling fan. This panel helps seal the airflow path and allows the radiator and fan assembly to be serviced without full disassembly in many cases.
Original lower shrouds frequently crack, break at the clip points, or become lost during radiator or fan work. Installing the genuine Nissan 21477-40P00 restores the correct lower seal and helps maintain proper cooling performance. Catalog sources confirm this shroud fits Fairlady Z32 and 300ZX models from approximately 1990–1996, including Twin Turbo applications (and certain NA configurations depending on the specific cooling setup).
Whether you are replacing a damaged or missing lower panel, refreshing the cooling system, or completing an engine bay restoration, this OEM lower fan shroud provides the factory fit and function required. At Terra Firma Automotive, we supply this genuine Nissan Lower Fan Shroud for Fairlady Z32 and 300ZX owners who prefer authentic cooling components. Choose Terra Firma Automotive for correct-fit Nissan parts that support reliable temperature control on the Z32 platform.
