A secure core plug is essential for containing coolant within the cylinder head. The genuine Nissan Cylinder Head Front Core Plug (part number 11052-D0102) is the threaded front core plug used on the Fairlady Z / 300ZX Z32, designed to seal the front coolant passage in the cylinder head.
This OEM threaded plug provides a reliable, serviceable seal at the front of the head. Over time original core plugs can corrode, loosen, or begin to weep coolant, especially on higher-mileage engines. Replacing a compromised plug with the correct genuine Nissan part restores proper sealing and helps prevent coolant loss in this critical location. The threaded design allows for controlled installation and future service compared with traditional press-in freeze plugs.
Whether you are addressing a weeping front core plug, performing cylinder head work, or completing a cooling system refresh, this is the correct OEM component for the Z32. At Terra Firma Automotive, we supply this genuine Nissan Cylinder Head Front Core Plug for Fairlady Z and 300ZX owners who prefer authentic factory sealing parts.
