OEM Cylinder Head Bolt for 1996-2002 Nissan Pathfinder models equipped with the VG33E powertrain.

Cylinder head bolts play a crucial role in securing the cylinder head to the engine block, creating a seal and maintaining proper compression in the combustion chamber. They are subjected to high temperatures, pressures, and stresses. 

Here are some scenarios where it may be necessary to replace a cylinder head bolt:

• Engine rebuild or cylinder head removal: When performing major engine repairs or overhauls that involve removing the cylinder head, it is common practice to replace the cylinder head bolts. This is because the bolts experience significant torque during installation, and their elasticity and clamping force may be compromised after removal.
• Over-torqued or stretched bolts: If the cylinder head bolts have been previously over-torqued or stretched beyond their limits, they may not provide adequate clamping force. This can result in compression leaks, coolant leaks, or loss of proper sealing between the cylinder head and engine block.
• Signs of damage or wear: Inspect the cylinder head bolts for signs of damage, such as visible cracks, deformities, or corrosion. If any bolts appear compromised or worn, it is recommended to replace them.
• Manufacturer's recommendation: Follow the vehicle manufacturer's maintenance schedule or guidelines. Some manufacturers specify a recommended interval for replacing cylinder head bolts, especially in engines that experience high loads or performance demands.
