3804133 Cylinder Head Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an exchange cylinder head, listed under the Engine group. The line raises the refundable charge on the worn head you send back; it is not a part and supplies nothing when ordered by itself. Under Volvo Penta's core numbering it pairs with part 3801133.

⚙️ Key Features

• Refundable core deposit, not a fitted part
• Pairs with part 3801133
• 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 rising in the header tank
• White smoke and a sweet smell at the exhaust once warm
• Misfire or 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 and head bolts before fitting the exchange head, and renew single-use bolts rather than reusing them

📦 Condition

• Refundable core deposit - not a physical part
