This is a complete cylinder head assembly, pre-fitted with a full gasket kit, designed for Volvo D6E engines used in various excavator models. It ensures proper sealing of the combustion chambers and efficient gas exchange, manufactured to precise tolerances, unlike a warped or cracked head that can cause leaks and performance issues. Operators may notice coolant loss, white smoke from the exhaust, or a drop in engine compression when this component fails.
Always verify with serial number before ordering.

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.
A failing cylinder head may initially present as coolant loss without visible external leaks or white smoke from the exhaust. As the issue progresses, engine performance will degrade due to loss of compression, and oil may mix with coolant or vice-versa. If left unaddressed, severe internal damage can occur, leading to complete engine failure.
Ensure the mating surfaces of the engine block and cylinder head are meticulously cleaned and free of any debris or old gasket material. Follow the manufacturer's specified tightening sequence and torque values precisely for the head bolts.
Inspect the pistons, connecting rods, and crankshaft for any signs of damage or wear when replacing the cylinder head assembly.
