397-1559 Complete Cylinder Head With Valves — Cat M315D2 M317D2

This is a complete cylinder head assembly, including pre-installed valves, springs, and guides, which forms the top seal of the engine cylinders. It is precision-machined from high-grade cast iron or aluminum to ensure optimal combustion chamber sealing and heat dissipation, unlike a cracked or warped head that can cause internal leaks. Operators may experience symptoms such as coolant loss, white exhaust smoke, rough running, or overheating when a cylinder head begins to fail.

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 signs of a failing cylinder head often include coolant loss without visible external leaks or persistent white smoke from the exhaust. If left unaddressed, the problem can escalate to coolant mixing with oil, leading to engine overheating and severe internal component damage. This poses a significant risk of complete engine seizure.

Installation Tip

Always use a new cylinder head gasket and ensure all mating surfaces on the engine block and cylinder head are perfectly clean and flat. Follow the manufacturer's specified torque sequence and values meticulously during installation.

Service Note

When replacing the cylinder head, inspect the engine block deck for flatness and check the condition of the pistons and liners.
