3803306 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head, weighing 90.718 kg and listed for 21 applications across the TMD, TD, AD, TAMD, MD and KAD31 and 32 families. The reman catalogue funnels three separate engine groups into this one number - the AD31, AQAD31, MD31, TAMD31 and TMD31; the AD31D, AD31L-A, AD31XD, TAMD31D, TAMD31L, TAMD31M and TMD31D; and the AD31P, KAD32P and TAMD31P. It is supplied ready for installation with valves and springs fitted, and camshaft-bearing housings included where applicable. It also consolidates three earlier numbers, 3581552, 3583896 and 3803307, all catalogued as cylinder heads. Supplied on an exchange basis: core deposit 3806306 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

🔌 Function

Seals the top of the cylinders and carries the valves, ports and injectors that control gas flow and fuel delivery.

⚠️ Common Signs of Failure

• Coolant disappearing with the header tank under pressure
• White smoke or steam from the exhaust once warm
• Bubbling in the expansion tank from combustion gas in the coolant
• Cracks around the valve seats or injector bores found on strip-down
• Head face out of flatness or sunk valve seats

🛠️ Service Notes

• At better than 90 kg this needs a hoist and pallet freight - it is not a two-man lift and not a parcel, so plan the handling before it arrives
• Three older numbers now lead here, so an old parts list quoting 3581552, 3583896 or 3803307 is pointing at this head
• Renew the head gasket and head bolts, have the block face checked for flatness, and sort out the cooling fault that took the old head first
