# 3804479 Base Engine Core | Genuine Volvo Penta Part

## 🔧 Product Description

Refundable core deposit raised against the exchange base engine on Volvo Penta part number 3801479, listed under Engine. It is an accounting line rather than a fittable part: the charge goes on when the exchange base engine is supplied and comes back off when the old base engine is returned, and nothing is shipped against the deposit itself. Five consecutive base engine deposits run from 3804476 to 3804480 with nothing in the record to tell them apart, so the paired unit number is the only safe guide.

## ⚙️ Key Features

-   Refundable core deposit, not a fittable part
-   Paired unit number 3801479
-   Nothing ships against this line
-   Credited back when the old base engine is returned
-   Listed under Engine

## 🔌 Function

Carries the refundable core charge on the outgoing base engine rather than doing any mechanical work itself. A base engine is the assembled engine supplied without the ancillaries that a particular installation adds to it.

## ⚠️ Common Signs of Failure

-   This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the base engine being exchanged
-   Compression low or uneven across the cylinders, with hard starting and heavy blow-by
-   Knocking or rumbling under load that does not clear with an oil change
-   Oil pressure falling away hot, with metal in the filter or sump
-   Coolant and oil mixing, or coolant pushed out of the tank when the engine is worked

## 🛠️ Service Notes

-   The charge is credited back once the old base engine is returned through the dealer; it has to go back complete and rebuildable, and a stripped, cracked or seized-solid base engine can be refused or the credit cut.
-   Ordering this number on its own supplies no part. It only makes sense raised alongside exchange unit 3801479, so confirm that unit is obtainable and check its exact designation before quoting.
-   This part of the block runs engine, base engine, longblock and shortblock deposits side by side; those are four different builds of exchange unit and the deposits are not interchangeable, so match the wording as well as the number.

## 📦 Condition

-   Refundable core deposit - not a physical part
