Carry out a reliable top-end repair with this Genuine Nissan Cylinder Head Bolt Set, designed to suit Nissan Patrol GU Y61 models fitted with the ZD30Di diesel engine. Supplied as a complete set of 18, these OEM head bolts secure the cylinder head to the engine block, maintaining the critical clamping force needed to seal the head gasket under extreme combustion pressure.

Cylinder head bolts are engineered as single-use, torque-to-yield fasteners on most modern diesel engines, including the ZD30Di. They stretch slightly during the initial torque sequence to achieve correct, even clamping load, and reusing old bolts after a head removal can result in insufficient clamping force. This risks a leaking or blown head gasket shortly after reassembly, undoing all the labour of the repair. Fitting a full set of new genuine bolts is essential whenever the cylinder head is removed, ensuring a reliable, long-lasting seal.

Manufactured to Genuine Nissan specifications from high-tensile steel, this bolt set is engineered to handle sustained combustion pressure and heat cycling. It's the correct replacement for head gasket repairs, top-end rebuilds, or any job requiring cylinder head removal on your Nissan Patrol ZD30Di.
