# 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
