Cylinder Head Bolt Set - Nissan Navara YS23 M9T

Cylinder Head Bolt Set - Nissan Navara YS23 M9T

These cylinder head bolts are critical components used to secure the cylinder head to the engine block on your Nissan's YS23 engine. This is a complete set of high-quality, single-use head bolts required for re-installing the cylinder head after repairs.

Modern head bolts, like these, are torque-to-yield (TTY) or 'stretch' bolts. They are designed to permanently stretch when tightened to factory specifications to achieve a precise and even clamping force. Because they are permanently deformed during their initial installation, they cannot be safely reused and must be replaced every time the cylinder head is removed, such as during a head gasket replacement or other major engine work.

Reusing old head bolts can lead to improper sealing of the head gasket. This can result in a catastrophic failure, including coolant and oil mixing, severe engine overheating, loss of compression, and ultimately, complete engine failure, leading to far more expensive repairs.
