3804255 Cylinder Head Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an exchange cylinder head, listed under the Engine group. It raises the refundable charge on the worn head you return and supplies no part when ordered on its own. Under Volvo Penta's core numbering it pairs with part 3801255.

⚙️ Key Features

• Refundable core deposit, not a fitted part
• Pairs with part 3801255
• Engine group

🔌 Function

Carries the refundable core charge on an exchange cylinder head; the head it covers closes the cylinders, carries the valves and injectors, and forms the combustion chambers.

⚠️ 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
• Coolant loss with no external leak, or bubbles in the header tank
• White smoke and a sweet exhaust smell once the engine is warm
• Misfire and low compression on one or two adjacent cylinders
• Cracks between the valve seats or into an injector bore found on strip

🛠️ Service Notes

• The deposit is refunded when the old cylinder head is returned; ordering this line on its own supplies no part
• Return the head complete with its valves and studs and the faces protected, since a stripped or damaged core can reduce or void the refund
• Check the block face for distortion and fit new head bolts rather than reusing stretched ones

📦 Condition

• Refundable core deposit - not a physical part
