Patrolapart Cylinder Head Bolt Set TD42 - Nissan Patrol Y60 GQ & Y61 GU

Cylinder Head Bolt Set - Nissan Patrol Y60 GQ Y61 GU TD42

This complete set of head bolts is used to secure the cylinder head to the engine block of your Nissan Patrol's TD42 engine. Head bolts are critical for maintaining the integrity of the head gasket seal, containing immense combustion pressures and keeping vital oil and coolant passages separate. As TD42 engines are often pushed to their limits with turbochargers and heavy workloads, the original head bolts are subjected to extreme stress. They are single-use, 'torque-to-yield' (TTY) bolts that permanently stretch when tightened to specification, meaning they cannot be safely reused for any engine work. Replacing them is an absolute must during a head gasket change or engine rebuild.

Ignoring the need for new head bolts and reusing the old ones is a recipe for disaster. Old, stretched bolts will not achieve the correct clamping force, leading to almost certain head gasket failure. This can result in catastrophic engine damage, including coolant and oil mixing, severe overheating, loss of compression, and a warped or cracked cylinder head.
