1556600 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta cylinder head is a genuine OEM service component used in the complete cylinder-head assembly. It is manufactured to the original Volvo Penta dimensions and interface requirements so the adjoining assembly retains its specified position and operating geometry. Maintains the revised OEM service configuration. In service, it houses the valves, seats, ports and combustion sealing surfaces at the top of the cylinder block. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556600 against the installed assembly before ordering.

🔌 Function

The cylinder head seals the top of the cylinder bores to form the combustion chambers and houses the valve seats, valve guides and injector locations. It also carries coolant and oil passages that feed the valve train and manage heat away from the combustion area.

⚠️ Common Signs of Failure

• Coolant loss, white exhaust smoke or coolant in the oil indicating a failed head gasket seal or cracked head
• Combustion gases pressurising the cooling system, causing header tank bubbling or overflow
• Compression loss, hard starting or misfire on one cylinder from eroded or receded valve seats
• Visible cracks, corrosion pitting or erosion around the injector bores and coolant passages
• Warped or uneven head face preventing a reliable gasket seal after overheating

🛠️ Service Notes

• Check the head for cracks and check the head and block faces for flatness with a straight edge before assembly, and have any doubt about the face or the valve seats resolved before the gasket goes on
• Clean the gasket faces with care and without scoring them — do not attack an aluminium face with abrasive discs or scrapers, and keep debris out of the bores, coolant passages and bolt holes
• Always use a new head gasket, and tighten in the stages, sequence and torque-plus-angle steps given in the workshop manual for your engine, with the threads and mating faces clean and lubricated exactly as that manual specifies
• Head bolts on modern engines are angle-tightened and stretch permanently, so renew them wherever the manual calls for it rather than reusing them
• Refill and bleed the cooling system properly, then run the engine and carry out any retightening or valve clearance recheck the manual requires after the first running period
