242-1811 26 Pieces Bolt Cylinder Head — Cat C11 C13

This 26-piece bolt cylinder head set is essential for securely fastening the cylinder head to the engine block, ensuring a proper seal for combustion and fluid containment. Manufactured to precise specifications, these bolts provide superior clamping force and resistance to heat and vibration compared to worn or mismatched fasteners. Operators might experience engine misfires, coolant leaks into the combustion chamber, or loss of compression if these bolts are loose or broken.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial symptoms of failing cylinder head bolts may include subtle engine performance issues like rough idling or slight power loss. If the bolts loosen further, coolant may leak into the cylinders, causing white exhaust smoke, or combustion gases may enter the cooling system, leading to overheating. The ultimate consequence is a loss of engine compression and potential internal engine damage.

Installation Tip

Always use a calibrated torque wrench and follow the manufacturer's specified tightening sequence and torque values. Ensure bolt threads are clean and lubricated as per service manual instructions.

Service Note

Inspect the cylinder head gasket and the cylinder head mating surface for flatness and damage when replacing the cylinder head bolts.
