🔧 Product Description

🚤 Compatibility

Typically suits:

• Volvo Penta TAD560VE
• Volvo Penta TAD561VE

• Engine Family: TAD

⚙️ Key Features

• TAD560VE cylinder-head application
• Four-cylinder, 16-valve heavy-duty diesel configuration
• Precision-machined combustion and coolant passages
• Supports the complete valve-train assembly
• Requires correct gasket selection, fastener procedure and installed-height checks

🔌 Function

The cylinder head closes the top of the cylinders, forms the combustion chambers, carries the valves and directs intake air, exhaust gas, coolant and lubricating oil through the engine.

⚠️ Common Signs of Failure

• Coolant pressurisation or loss
• Oil and coolant contamination
• Cracks between valve seats or coolant passages
• Valve-seat recession
• Warped gasket surface
• Combustion leakage at the head gasket

🛠️ 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
