3804334 Cylinder Head Core | Genuine Volvo Penta Part

🔧 Product Description

This is the cylinder head core deposit from the Engine group. It is the refundable charge on the cylinder head you return when buying the exchange unit, and it ships nothing on its own. It pairs with part 3801334, and that is the number that supplies the cylinder head itself.

⚙️ Key Features

• A deposit line, not a shippable part
• Refunded on return of the old cylinder head
• Pairs with part 3801334

🔌 Function

Carries the refundable charge on an exchange cylinder head, and is credited back when the worn cylinder head comes in.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the cylinder head being exchanged
• Valve seats sunk into the head, losing compression and making the engine hard to start
• Gasket face corroded or bowed beyond what a skim can recover
• Coolant disappearing with no external leak, and white smoke that will not clear once warm
• Combustion gas pushed into the coolant, pressurising the header tank and lifting the cap

🛠️ Service Notes

• The charge on this line is refunded on return of the old cylinder head.
• Ordering this number on its own supplies no part - the cylinder head comes from its paired line, part 3801334.

📦 Condition

• Refundable core deposit - not a physical part
