Maintain correct cylinder head clamping force and engine sealing with this Genuine Nissan Cylinder Head Bolt, designed for Nissan Patrol GQ Y60 and GU Y61 models fitted with the TD42 diesel engine. These OEM head bolts are critical fasteners that secure the cylinder head to the engine block, ensuring the head gasket remains properly compressed to withstand combustion pressures and maintain reliable engine performance.

Over time and repeated use, cylinder head bolts can stretch, weaken, or lose torque due to heat cycles and engine load. Re-using old or damaged head bolts increases the risk of head gasket failure, coolant leaks, compression loss, and engine overheating. Replacing them with genuine Nissan head bolts restores correct clamping force, helps maintain engine sealing, and supports long-term durability of your Patrol’s TD42 engine.

Manufactured to Nissan factory specifications, these genuine head bolts feature high-strength construction and precise threading for accurate fitment. They are direct replacements requiring no modifications for installation.
