Maintain the correct clamping force and ensure a reliable cylinder head seal with this Genuine Nissan Cylinder Head Bolt, designed to suit Nissan Patrol GU Y61 models fitted with the TB48DE 4.8L petrol engine. This OEM cylinder head bolt secures the cylinder head to the engine block, applying the precise clamping load required to seal the head gasket and withstand the extreme pressures and temperatures generated during engine operation.

Cylinder head bolts are torque-to-yield (TTY) fasteners, meaning they are designed to stretch during installation and should not be reused. Reusing old head bolts can result in insufficient clamping force, leading to head gasket failure, coolant and oil leaks, compression loss and potentially severe engine damage. Replacing them with Genuine Nissan components during any cylinder head or head gasket repair helps ensure long-term engine reliability and correct factory performance.
