22334537 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta cylinder-head assembly or service casting for a heavy-duty diesel engine. It forms the combustion-chamber roof and contains the valve, injector, coolant and lubrication passages. Supply content can vary by service specification, so valves, camshaft, injector sleeves, plugs and hardware must not be assumed included unless listed on the package.

⚙️ Key Features

• Genuine Volvo Penta cylinder-head component
• Precision-machined combustion, valve and gasket surfaces
• Original coolant and oil passage geometry
• Designed for the specified injector and valve-train arrangement
• Requires the correct head gasket, bolts and tightening sequence
• Confirm whether supplied bare, semi-complete or complete before installation

🔌 Function

Seals the top of the cylinders, houses the valve train and injector locations, and routes intake air, exhaust gas, coolant and lubricating oil.

⚠️ Common Signs of Failure

• Coolant loss, combustion pressure in the cooling system or overheating
• Low compression or cylinder imbalance
• External oil or coolant leakage
• Cracks between valves, injector bore or coolant passages
• Warped gasket surface
• Valve-seat, guide or injector-sleeve damage
• White smoke or coolant entering a cylinder

🛠️ 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
