Cylinder Head Bolt Set - Nissan Patrol GU Y61 ZD30Di Direct Injection

Cylinder Head Bolt Set - Nissan Patrol GU Y61 ZD30Di Direct Injection This Cylinder Head Bolt Set is a crucial component for securing the cylinder head to the engine block in your vehicle. These high-tensile bolts are designed to be tightened to a specific torque setting and then stretched a further amount, a process known as torque-to-yield. This creates the precise and powerful clamping force required to seal the head gasket effectively. Because these bolts are designed to stretch permanently upon installation, they are strictly single-use and must be replaced any time the cylinder head is removed. This is essential during major engine work such as replacing a blown head gasket, servicing the cylinder head, or a complete engine rebuild. Product Features High-Tensile Steel Construction: Manufactured from premium-grade steel to withstand extreme pressures and temperatures, ensuring reliable and consistent clamping force. Torque-to-Yield (TTY) Design: Engineered to stretch upon installation, providing the superior, evenly distributed sealing pressure required for modern multi-layer steel (MLS) head gaskets. Complete Engine Set: Includes all the necessary bolts to service one complete cylinder head, saving you the hassle of sourcing individual components. OEM Specification: Designed as a direct replacement for the original bolts, guaranteeing a perfect fit and straightforward installation process.
