# 3806309 Cylinder Head Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core deposit for a cylinder head, from the Engine group. It is the refundable charge raised against the old cylinder head when the exchange unit is bought, and it comes back once the worn cylinder head is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3803309, which is the number to quote for the component itself and the number to check availability against. It carries a published weight of 53.07 kg, which is the mass of the cylinder head itself and is what to plan the return leg around, since nothing goes out against the deposit. No other cylinder head core in this listing of 18 shares its published weight, but the lines are otherwise identical in name and group, so the paired unit number stays the reliable identifier.

## ⚙️ Key Features

-   Core deposit line, not a cylinder head you can fit
-   Belongs with the exchange unit, part number 3803309
-   Refunded when the old cylinder head is returned
-   Published weight 53.07 kg
-   Only cylinder head core here at this published weight

## 🔌 Function

As a line item it carries the refundable core charge on the exchange; the head itself closes the top of the cylinders, carries the valves, ports and injector seats, and holds the combustion pressure against the block.

## ⚠️ 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 disappearing with no leak to be found outside the engine
-   Bubbles rising in the header tank, or coolant pushing back when the engine is worked
-   White smoke and a sweet smell at the exhaust once the engine is hot
-   Cracks between the valve seats or around the injector bore, or a face pulled beyond the permitted skim, found on strip-down

## 🛠️ Service Notes

-   The charge is refunded when the worn cylinder head is returned, so keep the old unit and send it back rather than scrapping it
-   Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3803309
-   At 53.07 kg the old cylinder head is a lifting job and goes back as freight rather than as a parcel, so book the return leg when the exchange unit is ordered
