Cylinder Head Bolt Set - Nissan Navara YD25

Cylinder Head Bolt Set - Nissan Navara YD25

This cylinder head bolt set is used to fasten the cylinder head to the engine block in your Nissan's YD25 engine. These bolts are a critical component responsible for maintaining the seal created by the head gasket under immense pressure and temperature variations.

As cylinder head bolts are a 'Torque-to-Yield' (TTY) design, they permanently stretch when tightened to the correct specification. This means they are a single-use item and must be replaced every time the cylinder head is removed for any reason, such as replacing a head gasket or performing an engine rebuild.

Failure to replace old head bolts can result in an improper seal between the cylinder head and the engine block. This can quickly lead to a blown head gasket, causing coolant and oil to mix, loss of compression, severe overheating, and ultimately catastrophic engine failure.
