3804357 Cylinder Head Core | Genuine Volvo Penta Part

🔧 Product Description

Cylinder head core deposit, listed under Engine. It carries the refundable charge raised against the worn cylinder head you send back when an exchange unit is bought, and it is an accounting entry rather than a part - nothing ships against the number. The matching line is part 3801357 - order that for the cylinder head.

⚙️ Key Features

• A deposit line, not a shippable part
• Refunded on return of the old cylinder head
• Pairs with part 3801357

🔌 Function

Books the refundable deposit on an exchange cylinder head and closes it out on return of the old one.

⚠️ 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
• 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
• Cream or mayonnaise-coloured emulsion under the oil filler 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 3801357.

📦 Condition

• Refundable core deposit - not a physical part
