245-4324 Cylinder Head — Cat 3406

This is a replacement cylinder head for CAT 3456, 3406, 3406C, and 3406E engines, forming the top seal of the combustion chamber. It is manufactured to precise tolerances to ensure proper sealing of combustion gases and coolant flow, unlike a warped or cracked head which can lead to internal leaks. Operators may observe coolant loss, white exhaust smoke, or engine overheating when a cylinder head fails.

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

Common symptoms of a failing cylinder head include coolant loss without visible external leaks, white smoke from the exhaust indicating coolant entering the combustion chamber, or engine overheating. If left unaddressed, these issues can lead to severe internal engine damage, including hydro-locking or catastrophic component failure. Continued operation risks significant damage to the engine block and other critical components.

Installation Tip

Ensure the cylinder block deck is perfectly clean and flat before installing the new head gasket and cylinder head. Never reuse an old head gasket, and always follow the manufacturer's specified torque sequence and values for cylinder head bolts.

Service Note

Always replace the cylinder head gasket and inspect the engine block deck for flatness when installing a new cylinder head.
